Installation of Resellers Center For WHMCS requires a few simple modifications of the template files.

No worries, we will guide you step by step through the entire installation process.

Note: If you still use any of Resellers Center For WHMCS previous versions prior to v3.x, read about it here.

Important: If you are updating Resellers Center For WHMCS from the 3.8.0 version (or prior to 3.8.0) to the 3.9.0 version and later, you need to reconfigure your API settings.
Please refer here for the detailed instruction.


1. Log in to our client area and download the module.
R3 1 new.png
2. In the downloaded file you might find one or two packages that support different PHP versions.

In the most recent versions of the module, you will find only one package that supports PHP 7.4 and later.

PHP74 81.png
Previous updates of the module may contain two packages dedicated to various PHP versions.

The first one supports PHP 5.6 up to PHP 7.3, and the second one addressed to PHP 7.4 up to PHP 8.1.
Note: Keep in mind that PHP versions 5.6 up to 7.3 are no longer officially supported and their security issues are not fixed or released any more. Find more info here.

PHP56 74 81.png
Note: You can check the current PHP version in your WHMCS. To do so, proceed to 'Utilities' → 'System' → 'PHP Info'.
3. Extract the package and upload its content into the main WHMCS directory.

The content of the package to upload should look like this.

R3 2 1.png
4. When you install Resellers Center For WHMCS for the first time you have to rename the 'license_RENAME.php' file.

The file is located in 'modules/addons/ResellersCenter/license_RENAME.php'. Rename it from 'license_RENAME.php' to 'license.php'.

R 3.png
5. In order to configure your license key you have to edit the previously renamed 'license.php' file.

Enter your license key between quotation marks as presented on the following screen.
You can find your license key in our client area → 'My Products'.

R 4.png
6. The next step is setting up the 'storage' and 'config' folders as writable.

They are located in: 'your_whmcs/modules/addons/ResellersCenter/'.

8. In the next step, you need to permit access to the module.

To do so, select the admin roles which should have access to the module.
You might as well enable hooks to ensure that all the module's functions work as intended (recommended).
Optionally, choose whether you want to allow your reseller's end-clients to perform orders in your main store or to make them purchase products only through the reseller's store.
Finally, decide whether the services ordered by clients via the reseller's store should be shown or hidden when a client logs in to the administrator's main store instead of to the branded reseller's store.

Press 'Save Changes' when ready.

R3 7 new.png
9. Afterward, go to 'Addons' 'Resellers Center' 'Integration Code' and follow the instructions.

Note: Please keep in mind that WHMCS versions prior to V8.4 are no longer officially supported by the module.

Note that this payment gateway is required if you are going to use any of the following module features:

  • Deferred Payments
  • Consolidated Invoices
R3 10 0.png

Management and Configuration

Management of Resellers Center For WHMCS is very convenient. You can supervise everything from the addon.

What is more, the module extends possibilities of both your resellers and their customers.
Let us find out what our product can do!


In this section you can find more information about a global configuration.

Additionally, here you can also read about the details of migration.

Global Configuration

In the 'Configuration' tab you can set up global settings of the module. You can define 'General', 'Billing' and 'Email Templates' settings.

Please note that these settings are default for all resellers. Read this section through to find the details of configuration per each reseller.

General Settings

  • Store Branding - Allows resellers to set up a custom logo, company name and domain.
  • Allow Products - If enabled, resellers will be able to sell properly configured products in their own stores.
  • Allow Domains - Gives resellers the possibility to sell domains in their own stores.
  • Allow CNAME - It enables the support for CNAME record pointing from the customer's domain. A new field named 'Domain' should appear in the 'Configuration' section of the 'Reseller Area'
  • Log In As Client - If this option is enabled, the resellers can log in as the client.
  • Place Orders - If this option is enabled, the resellers can place orders on behalf of the client.
  • Suspend Services - If this option is enabled, the resellers can suspend the client's services.
  • Allow Promotions - If enabled, the reseller's end-clients will be able to use promo codes in the reseller's store configured by the resellers in the 'Promotions' section.
  • Show Hidden - If enabled, the hidden products and groups will be visible to resellers' clients.
    Thanks to that functionality, there is a chance to configure special products destined for resellers exclusively. These will not be accessible in the main Administrator's store.
  • Hide Delete Client Option - If enabled, the reseller will not be allowed to delete a client from the reseller area.
  • Configurable Options Commissions - If enabled, resellers will receive commissions from configurable options. This feature can be used with the following 'Calculation Methods' :
    • Percent Rate,
    • Administrator Percent With Fixed Rate,
    • Reseller Percent With Fixed Rate.
      Important: 'Configurable Options Commissions' feature is not available if the 'Reseller Invoice' option is enabled in 'Billing Settings'.
  • Redirect Emails - If enabled, all emails received by the client will be also sent to the reseller.
  • Change Mail Settings - If enabled, the reseller can set custom email settings.
  • Change Date Format - If enabled, the reseller can set a custom date format which will be displayed on their clients' pages.
  • Hide Single Sign-on - If enabled, Single Sign-on featured is hidden in the reseller's store.
  • Global Search - If enabled, the "Search" section will be visible in the Reseller Area.
  • Ticket Departments - Allows you to choose ticket departments available for end clients as they will contact resellers.
  • Templates - Allows you to select client area templates of the reseller store.
  • Order Templates - Allows you to select order templates set for a cart view in the reseller store.

  • Default Reseller Documentation - Select the default documentation to show for new resellers.
R3 11.png

Billing Settings

  • PayPal Auto Transfer - Enables automatic transfers to a reseller's account.
  • Invoice Branding - If enabled, resellers can brand the number and basic information on the invoice.
  • Reseller Invoice
    • When the 'Reseller Invoice' option is off:
      When end clients place orders in the reseller store, the invoice will be created by WHMCS with the admin details (provided earlier in 'General Settings' ).
      Once the invoice is paid, the module calculates the profit in accordance with the product configuration in the reseller group.
      The calculated amount goes to 'Payouts' where the admin can transfer it via PayPal or credits to the reseller account.
      Find out more about calculation and pricing methods here.
    • When the 'Reseller Invoice' option is on:
      There are two invoices generated after placing an order in the reseller store. The first invoice is created by the reseller and sent to the client
      while the other one is generated by the admin and delivered to the reseller. The amount invoiced is taken directly from the admin charge for the product (reseller group configuration).
      In this case, calculation methods are not included and the reseller earns on price differences between invoices.
      Moreover, this option also permits resellers to use their own configuration data in payment gateways settings.
      Once they do it, end clients are able to make payments directly to the reseller account and the reseller settles debts with the administrator using prepaid WHMCS credits.
      Important: When you enable this option and any invoice is created in the meantime, you will not be able to disable it anymore!
      Note: 'Configurable Option Commissions' option is unavailable if the 'Reseller Invoice' option is on.
  • Deferred Payments - If enabled, your resellers will be allowed to define limits for deferred payments for their clients
  • Gateways - Allows you to select gateways that resellers can enable in their own stores. This option is only available if 'Reseller Invoice' is disabled.
  • Sequential Invoice Number Format - Required if 'Reseller Invoice' is enabled.
  • Deferred Payments Limit - Set the limit of deferred payments for your resellers. If you leave 0, the feature will be simply disabled and settings taken from the Pricing Group used.
    To use this option the 'Reseller Invoice' option must be enabled.
R3 11 1 new.png

Email Templates Settings

Here you can enable/disable numerous options that a reseller can customize later on.
These templates are related to emails regarding issues like:
  • General
  • Product
  • Domain
  • Support
  • Invoice
  • Invite
  • User
R3 11 2.png

Single Reseller Configuration

Global configuration settings, enumerated and explained above, can be also defined for particular resellers. You may alter them for a single reseller, the global settings will be overwritten by these ones.
Go to the 'Resellers' tab and press the marked button to continue.
R3 11 3.png
Here you will find the details related to the chosen reseller. In the 'Configuration' section you can select preferred 'General', 'Billing', 'Miscellaneous' and 'Email Template' settings.
Under the first tab, you will find exactly the same options to configure as in the global settings.
R3 11 4 new.png
The 'Billing Settings' section includes global and some additional configuration details per reseller:
  • Turn Off End Client Invoices - If this option is set to enabled, the end client will not receive the created invoices.
  • Credit Payment - This option, when enabled, gives the reseller's clients the possibility to pay using credits.

There are also features related to the deferred payments and consolidated invoices specific settings:

  • Deferred Payments - Enable to allow resellers to restrict the orders placed by end clients to the total amount defined in the 'Deferred Payments Limit' setting (defined by the reseller per end client).
    Keep in mind that the end client will still be allowed to choose if he wants to make instant payments using:
    • standard methods (gateways, credits, bank transfer, etc) or
    • postpone the payment ("Deferred Payments" payment gateway) but only if the order amount is lower than the limit
  • Verify Reseller Limit - When activated, this feature enhances order validation by considering both the end-client's and the reseller's deferred payments limit. If the reseller's credit is insufficient, a notice will suggest contacting them.

Services ordered with the deferred payment option enabled will be immediately activated. To be allowed to place further orders with deferred payment, the end client has to first pay all the existing invoices.
In case the consolidated invoices feature is turned on, the client cannot pay the order right after completing it. The consolidated invoices can be paid manually once generated.

  • Deferred Payments Limit - Define the limit for deferred payments for the reseller. If "0" is entered, the feature will be disabled. The logic is the same as in described above option for end clients.
    ("Reseller Invoice" option must be previously enabled)
  • Consolidated Invoices - ('Reseller Invoice' - enabled) All ordered items will be packed into one bundled invoice generated once a month, these include the invoices created for the resellers with purchased by them items (Reseller-Admin relation).
    When consolidated invoices are used, there is no possibility to make payments for ordered services with traditional payment methods right after completing the order.
    • Enabled
    • Disabled
    • Pricing Group Settings - settings defined in the reseller's pricing group are used.
      All resellers who belong to the same group will have the same settings related to consolidated invoices (Enabled/Disabled).
  • Consolidated Invoices Generation Day - Select a day of the month when consolidated invoices (Admin - Reseller relation) will be generated.
    In case the day of generation is set to a greater one than there are days in the month, the invoice will be generated on the last day of the month.
    If you enter "0", the pricing group settings will be used.
  • End Client Consolidated Invoices: - allow your reseller to use the consolidated invoices feature in their stores.
    The end clients will not be allowed to pay the order instantly after placing the order as the dedicated invoice will not generate. Only one bundled payment is allowed once a consolidated invoice is generated.
    • Enabled
    • Disabled
    • Pricing Group Settings - settings defined in the reseller's pricing group are used, all resellers who belong to the same group will have the same settings related to consolidated invoices.
      The generation date of consolidated invoices between the end client and the reseller is defined in the reseller's area.
  • Remove Zero Invoices - if enabled, invoices with zero amount (total amount on the invoice) will not be published.
    Note that already existing invoices will not be removed, only the ones generated after turning on this option will be checked and deleted if they fulfill the requirement.
  • Disable Consolidated Zero Invoices - if enabled, consolidated invoices with zero amount (total amount on the invoice) will not be published.
    Note that already existing invoices will not be verified, only the ones generated after turning on this option will be checked and if the requirements are met, such invoices will not be generated.
R3 11 6.png
Under the 'Miscellaneous' tab you will find these options available per reseller:
  • Turn Off Login To Main Brand - If this option is enabled, the reseller's clients will not be able to log into the main WHMCS store.
  • Turn Off KnowledgeBase - This option allows you to disable access to the KnowledgeBase for the reseller's clients.
  • Allow Promotions - This option enables the promotions in the reseller's store.
  • Allow Mail Wrappers Change - If this option is enabled your resellers will be able to change a global mail header, footer and CSS for their email messages.
    Important: If enabled, please inform the reseller that the fields are obligatory. If left empty the module will use the WHMCS default settings.
    Exemplary settings can be found in 'WHMCS System Settings' → 'General Settings' → 'Mail'.

  • Hide Delete Client Option - If this option is enabled, the reseller has no access to the Delete Client feature in the Reseller Area.
  • Hide Log In As Client Quick Action - If enabled, the reseller has no access to the 'Client Details' page in the Reseller Area.
  • Hide Client Details Action - If enabled, the reseller has no access to the 'Login As Client' feature in the Reseller Area.
  • Send Default Emails - If enabled and the email template is disabled in the 'Emails Templates' tab, the standard WHMCS email is sent for it. Otherwise, the email is not sent at all.
  • Change Mail Settings - If enabled, the reseller will be allowed to manage the custom e-mail settings.
  • Change Date Format - If enabled, the reseller will be allowed to configure the date format, display on their clients pages, individually.

Note: Once the configuration of your brand is complete, your reseller will still need to set up a CNAME DNS record if domain is used.
This record will point from the branded domain towards the reseller main domain used by WHMCS.

  • For example: if 'Reseller Invoice' is disabled there will be an option to provide reseller PayPal emails but resellers will not be able to configure available payment gateways on their own:
R3 30 new.png
  • However if 'Reseller Invoice' is enabled there will be an option to configure payment gateways by resellers or enable 'Auto WHMCS Invoice Payments' .
R3 30 0.png
  • Should you decide to enter the URL to your 'Terms of Service' page, an additional field will appear during the ordering process.
R3 30 10.png
Email Templates
'Email Templates' is a place where you can view and edit email templates sent to your clients.

Provided the option 'Allow Mail Wrappers Change' has been enabled for the reseller, empty fields to edit the CSS Styling, Header and Footer will appear.
Important: If this option is available, you must fill in these three fields correctly or otherwise issues with email formatting are sure to occur.
You may use and alter general WHMCS settings available under: 'WHMCS System Settings' → 'General Settings' → 'Mail'.

To edit an email template, press the 'Edit' button next to the template you wish to alter.

R3 30 1 new.png
Finally, edit the email template to suit your needs and press the 'Save Changes' button.

Note: During this step you can easily add merge fields using dropdown menus visible on the following screen.

R3 30 2.png
Payment Gateways
'Payment Gateways' - this tab is only available if the 'Reseller Invoice' option in the admin area is set to 'Enabled' .

In this section, the reseller can set up their own payment gateway ('PayPal', 'Stripe', 'Bank Transfer', '2Checkout, Authorize.Net Aim', '', 'Payflow Pro', 'Billplz'and 'WePay' gateways are currently available).
Thanks to this, all payments made by end clients are transferred directly to the reseller's PayPal account or bank institution.

A payment gateway named 'Deferred Payments' is dedicated to the module features "Consolidated Invoices" and "Deferred Payments" features. It is available only if at least one of them is enabled.
The payments between the reseller and the administrator are settled through the reseller's previously supplied credit balance.

R3 30 3.png
Email Settings
The Email Settings section allows the configuration of your own email mailbox. Enter the SMTP details to send messages.
Remember to test the connection and send testing email messaged to ensure everything works correctly before saving the whole configuration.

Important: Please bear in mind that "gmail" mail provided is not supported for reasons that are currently beyond our control.

R3 32.png
Consolidated invoices settings:
  • Enable Consolidated Invoices - enable the option to create one bundled invoice once a month with all ordered by the end client items in your store
  • Consolidated Invoices Generation Day - choose the day of the month when the consolidated invoice will be generated.
    If you set it to, for example, 31, the invoice will be generated on the last day of the month (if that is shorter than 31 days).
  • Default Credit Line Limit - this value limits total deferred payments per customer, it will be applied by default in cases where the limit is not specified for a given customer manually.
R3 32 0.png
Data Export
Export data to CSV files and via API:
  • Customer Details
  • Products
  • Product Addons
  • Domains
  • Invoices
  • Transactions
R3 32 1.png


Here is the detailed list of end clients' all invoices together with their status.
  • If the 'Reseller Invoice' option in the admin area is 'Disabled' , the listed invoices are generated between the end client and the site administrator.
  • If the 'Reseller Invoice' option in the admin area is 'Enabled' , the listed invoices are issued between the end client and the reseller directly.
R3 46 new.png
Using the 'Action' button on invoices list resellers can also view and manage the invoice details, similarly to how it is done in the admin area.

Press the marked button to download the invoice in a PDF format.

R3 46 2.png
Add a custom invoice. This option is available only for branded invoices between the reseller and the client.
  • Create - press to create the invoice draft, the invoice will not be available for the end client yet
  • Publish - an invoice is created, it is available for the end client instantly
  • Publish and Send Email - an invoice is created and an additional email is sent to the client
R3 46 3.png


This section allows you to view all of the orders with their chosen payment method and status.
R3 31.png
Apart from the general section with all orderes listed, you may view a list of ordered products, addons and domains separately.
Use visible filters to seach for specific orders only.
R3 31 1.png


In the 'Promotions' section resellers can generate fully customizable promo codes in order to apply a promotion for products, addons or domains of your choice.

Note: You must first enable them in your 'Configuration' section of a specific reseller.
Resellers can use the promo codes created only via the module itself, default WHMCS promotions cannot be applied.

R3 498.png
Click on the symbol, marked on the screen below to create one.
R3 461.png
Now you should see all fields required to properly configure a promotion.
  • Promotion Code - You need to create a new code, your customers will need it to receive a discount.
  • Type - Choose one of the available promotion types.
  • Recurring - Once set, a discount will apply to renewal invoices. If the field's value is set to 0, all future renewals will be discounted.
    Enter a different number to specify the exact sum of cycles the discount will last for.
  • Value - Provide the amount of the discount.
  • Start Date - Optional. In case a date is selected, the promotion will start working after the set date.
  • Expiry Date - Optional. The promotion will stop working at the end of the chosen day.
  • Max Uses - Optional. By proving a number you can define the number of allowed uses.
  • Uses - Current usage of the promo code.
  • Applies To - Select what products/addons/domains are eligible for the promotion.
  • Requires - Choose products/addons/domains that are required for the promotion to be applicable.
  • Billing Cycles / Periods - Decide which billing cycles and periods are required for the promotion to apply.
  • Lifetime - In that scenario, a discount will be preserved even if clients upgrades/downgrades their service in future.
  • Apply Once - In case of ordering multiple qualifying products, a discount will be applied once.
  • New Sign Ups - The promotion can be used by new clients only.
  • Once Per Client - When a client has already an existing active order a second use of the code will not be possible.
  • Existing Client - The promotion can be used only by existing clients with 1 or more active orders.
R3 462.png
By toggling the 'Upgrades / Downgrades' section, you will have a few extra fields to configure.
  • Upgrade Type - Select a suitable type of the upgrade the promotion applies to.
  • Discount Type - Choose a type of the upgrade promotion.
  • Discount Value - Enter a rate of the discount.
  • Upgrades Of Configurable Options - Provide an amount of the discount.
  • Notes - Any notes will be visible for you and for administrators exclusively.

There are two ways to add a product to an end client account, we will show you both of them below.

Assign Product by Reseller

Your resellers can place orders for their own customers as if the orders were for themselves.
R3 34.png
Both your reseller and the end client will receive an order confirmation email.

Afterward, when an end client logs in to the WHMCS client area, he/she will be able to view and manage previously ordered products.
End clients can also list and pay invoices or create tickets (if these options are checked in the addon module).

R3 35.png

Access Order From The Client Area

Your reseller's clients can view the order form with the list of products configured by their resellers.

Therefore, your reseller's clients can place orders on their own, using order forms in the client area.

R3 37.png
If 'Deferred Payments' is enabled for end clients, a dedicated payment gateway is available to select.
If the client has not reached the imposed limit, the payment can be postponed in time.
R3 37 0.png

Tickets Management

If you have not disabled tickets in your addon, your resellers will be able to reply and forward tickets created by their clients.

It is only available for tickets department set in the Resellers Center For WHMCS configuration.

R3 38.png
On the screen below you can see a list of all the tickets created by a reseller's clients from the client area.
R3 39.png
You can easily reply to them.
R3 39 1.png

Client Area - End Client

An end client sees a branded client area.

Since version 3.x of the module end clients are treated as regular WHMCS clients.

R3 40.png
Start New Billing Period - end clients when upgrading their services are given the possibility to start a new billing cycle for the upgraded service.
Keep in mind that the price for the upgrade is then recalculated adequately to the remaining, unused period of time.

This option is available if the "Consolidated Invoices" feature is enabled in the Reseller Area.

You may also force this feature to be always available for end-clients by replacing the "upgradesummary.tpl" template with a new one (available since version 3.13.0).

Find the below listed files:

  • 'upgradesummary.tpl' and rename it to upgradesummary_old.tpl (or delete it)
  • 'upgradesummary_rename.tpl' and rename it to upgradesummary.tpl

From now on, the "Start New Billing Period" feature will be always available regardless of the "Consolidated Invoices" feature status.
The end client will see a notification if they have an insufficient credit limit to proceed with the order (related to deferred payments only).

Note: "Start New Billing Period" feature is not available in the admin store, resellers upgrading their services are not permitted to use it.

General Relations

Relations between Provider, Reseller and Client
Payment system:

In general, Reseller receives a product from the Provider and then provides it further to the End Client.
Since the release of v3.0.0 the payment between the Reseller and Provider will be regulated by WHMCS credits but it can be also regulated manually or automatically to the Reseller's PayPal account.

Invoicing system:
  • If the 'Reseller Invoice' option in the admin area is Disabled, the invoices are generated between the end client and the site administrator.
  • If the 'Reseller Invoice' option in the admin area is Enabled, the invoices are issued between the end client and the reseller directly.
    Note: A separate invoice is created directly between the reseller and the provider in this scenario. That is why recurring payment automation is not supported and the generated invoices must by paid manually

Branded Domains & Aliases Configuration

In this section you will find guides on how to create branded domains and aliases in popular control panels.
Please keep in mind that there are multiple combinations, that may occur. Take a closer look to find a perfect solution for your case.

Apache2 / NGINX

If there is no cPanel/DirectAdmin/Plesk panel on your server, then all you need to do is modify the current configuration:
  • for NGINX - add the additional domain name in the server_name line (read more)
  • for Apache - add the additional domain name into the ServerAlias line (read more)

cPanel / DirectAdmin / Plesk Servers

Same Server + One Account/Subscription

This configuration of Same server + One Account/Subscription assumes that all domains are added within one account/subscription on a given server.
In this case, simply add an additional domain so that it points to the same directory as the WHMCS main domain points to. If a given panel has 'Aliases' option in its offer, you can also use it.

Same Server + Multiple Accounts/Subscriptions

Such scenario (Same Server + Multiple Accounts/Subscriptions) is not feasible.
This is due to the way web panels work (separation of users), not the module limitations.

Separate Server

A separate server - in this situation the branded domain is added to other DNS server. It might be added to, for example cloudflare, or it is added and used on another server, for example cPanel or DirectAdmin.

Take a look at the exemplary situation. Let's say there are two domains:

  • domain on server 'X'
  • domain on server 'Z' ('Z' can be a 'cPanel' server or a 'DNS' service)

In order to process it correctly, follow the below steps:

  • add an addon domain or an alias with the domain to server 'X', so that it points to the main domain, that is in our case
  • add a DNS record to the server 'Z' (note it can be e.g. cPanel or DNS service)
    • add a record 'A' pointing to the server 'X' IP address
    • or add a CNAME record pointing to the main domain, that is' in our case

SSL Certificate

If reseller branded domains or your WHMCS main domain use the SSL connection, they should also support selected certificates.

The supported types of certificates:

  • Dedicated SSL Certificate - handled separately for each domain.
  • Wildcard - if all brands and main WHMCS use the same domain.
  • SAN - if your brands and main WHMCS use different domains.

This is the way WHMCS works. It is not the limitation of our module which uses the 'WHMCS System URL' scheme.


Installing the SSL certificate for domains managed from cPanel consists of the following steps:
1. Log in to your cPanel and press 'SSL/TSLS Manager' under the 'Security' section.
2. Click on 'Manage SSL sites' under 'Install and Manage SSL for your site (HTTPS)'.
3. (installing the certificate) Select the domain, paste certificate and the private key, and save settings.
4. (using the already installed certificate) Select it from 'Browse Certificates' , and save settings.
You can also consider enabling the AutoSSL solution, which should automatically installs domain-validated SSL certificates. Go here for more information.

Note: AutoSSL function will rather not work for CNAME entries so you should use virtual hosts (vhosts) instead.


1. If your WHMCS is installed in a subdirectory, your resellers using CNAME record must provide their links with it.

For example, instead of
You can change that behavior through adding the below code to .htaccess file:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^$ [NC]
RewriteCond %{REQUEST_URI} !^/whmcs-directory/
RewriteRule ^(.*)$ /whmcs-directory/$1 [R=301,L]

Result: If hostname is not and path is not whmcs-directory', then redirect to resellers domain with /whmcs-directory.

2. When it comes to our Resellers Center For WHMCS and Social Media Login For WHMCS modules, they are compatible and work faultlessly unless your reseller uses a branded domain.
3. If you enable the 'Reseller Invoice' option and any invoice is created in the meantime, you will no longer be able to disable this option.
4. If you would like to use Google reCAPTCHA for brand storefronts, you need to add the domain addresses of those brands to the reCAPTCHA configuration.
To do so, please proceed here.
MB2 41 1.png
5. Consolidated invoices logging system - the module offers the possibility to extend the log entries related to consolidated invoices creation.

If you need additional information to be logged after every cron execution and generating a consolidated invoice, please:

  • find and open file 'config.json' located at: modules/addons/ResellersCenter/config/config.json
  • in the section "consolidated" change the "debug" parameter from false to true

Note: Please bear in mind that this option is not suggested for the production environment as it might significantly slow down the process of generating consolidated invoices and increase the number of logs.

MB2 41 2.png
MB2 41 3.png
6. Hiding gateways for resellers - you may permanently hide single payment gateways for all resellers regardless of their billing settings.

To do so:

  • find and edit file 'config.json' located at: modules/addons/ResellersCenter/config/config.json;
  • include the names of the gateways you would like to remove from your reseller under the "bannedGateways": [ part (see the screen below).

As a result, in the Reseller Area configuration, the reseller will not see these payment gateways, meaning there will be no way to enable them or modify their settings.

RC3 Tip 1.png

Update Instructions

An essential manual through the process of updating the module is offered here.

When you upgrade the module from a version older than 3.5.0 to 3.5.0 or newer, please remember to set writable permissions to the 'config' directory, as described in step 6. of the installation guide.

Before upgrading your WHMCS to version 8.9.0, it is strongly recommended to execute the following command, for instance, via phpMyAdmin:

 ALTER TABLE `ResellersCenter_BrandedInvoices` DROP FOREIGN KEY ResellersCenter_BrandedInvoices_ibfk_1;


Migration tool allows you to upgrade Resellers Center For WHMCS module to the latest version.

Note: Version 3.x currently supports migration from version 2.5.x of the module and it will only transfer data on resellers, resellers' clients and resellers' groups.
Therefore, the other settings of the module need to be reconfigured manually.

To perform the migration simply overwrite old files to the latest version of the module and refresh the addon page in the admin area.

External API Configuration

From the 3.9.0 version of Resellers Center For WHMCS, the module uses External API instead of Local API.
To begin with the configuration, please navigate to 'Configuration → WHMCS API Connection Settings' . Now, click on the link as presented below.
R3 40 1.png
Once you are in the 'Manage API Credentials' section, go to 'API Roles' and press 'Create API Role' .
R3 40 2.png
Enter your 'Role Name' and decide which API actions will be allowed. Do not forget to save the changes.

The API requires a minimum set of permissions, which include:

  • Orders: AcceptOrder
  • Addons: UpdateClientAddon
  • Domains: UpdateClientDomain
  • Products: UpdateClientProduct
  • Billing: AddCredit, ApplyCredit, UpdateInvoice
  • Service: ModuleTerminate, ModuleSuspend, ModuleUnsuspend
  • Tickets:AddTicketReply
  • System: SendEmail
  • Client: AddClient, UpdateClient
  • User: UpdateUser, ResetPassword
R3 40 3.png
Next, navigate to the 'API Credentials' section and click the 'Generate New API Credential' button.
Provide a description and choose the previously created API role. Finally, press the Generate button.
R3 40 4.png
You will find your new 'Identifier' as well as 'Secret' . Copy them and paste to a safe place because you will not see them again.
R3 40 5.png
Now, come back to the configuration section of the module. Provide your 'Identifier' and 'Secret' .
You also need to complete 'Base Auth Login' and 'Base Auth Password' if your site uses them.
R3 40 6.png
The final step is to navigate to 'General Settings' of your WHMCS admin area. Find the 'Security' section there and scroll down to the 'API IP Access Restriction' feature.
Enter your IP address here to make sure that the configuration will work properly.

Upgrade Guide

Seeking a solution that offers greater flexibility, customization tailored to your precise needs, and unrestricted availability?
There is an option that not only proves to be cost-effective in the long run but also includes prioritized support services, making it a truly valuable investment.

Opt for the Open Source version of your Resellers Center For WHMCS module to unlock these benefits.
Simply click on either the Get Source Code or Upgrade To Lifetime button found on the product's page in our client area to complete the one-step upgrade process, with a dedicated discount already applied.

Follow a comprehensive guide covering the transition process, the advantages it brings, and step-by-step instructions on what to do next after the order has been successfully finalized.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. If you use HTTPS, remember to implement a redirect from HTTP to HTTPS on the reseller's domain.

Otherwise, WHMCS will route visitors to the main WHMCS and not the reseller store. Keep in mind that when WHMCS creates the redirection, the domain is changed as well.

3. We do not recommend using Resellers Center For WHMCS with:
  • Multibrand For WHMCS
  • SMS Center For WHMCS (due to e.g. separate email templates used)
  • Discount Center For WHMCS (due to e.g. not branded invoices)
  • Quotes Automation For WHMCS (due to e.g. not branded emails or invoices)
  • Hosting Quota Notifications For WHMCS (due to e.g. not branded emails)
  • Zendesk For WHMCS and Freshdesk For WHMCS (due to e.g. not branded ticket messages)
  • CRM For WHMCS (due to e.g. not branded emails)
  • Payment Gateway Charges For WHMCS (due to e.g. interference in the invoices by both modules which causes conflicts)

Integration between these modules is hampered due to specific features of each one of them and their individual work flow.
That is: separate email templates used or common hooks that override one another (Multibrand and Discount Center), etc.
We are continually working on eliminating these limitations wherever possible.

  • Domain Orders Extended For WHMCS - the module integration is slightly limited for reseller clients who use the Allow CNAME option.
4. Please remember that Resellers Center For WHMCS is guaranteed to work smoothly with 'Six', 'Twenty-One' And 'Lagom' templates.

If you are using some custom template, please be mindful that the module may not combine well with it out of the box, which may result in unexpected errors.
In this case, you can take advantage of our Template Integration service and have all interface elements carefully harmonized by our team.
You can order Template Integration together with the module as well as, at any time later on, in the client area - in the "Services" section of your product's page.

5. The Lagom Client Theme missing integration:
  • If you experience difficulties with displaying the available billing cycles selection on the review & checkout page, consider either changing the template in use or adjusting the Lagom Theme settings.
    To address this, enable the 'Hide product billing cycle dropdown' option. This will utilize the standard WHMCS form, eliminating the need to change your template.
  • Note that unexpected issues may arise when using both the Lagom Client Theme and the Stripe payment gateway. In such cases, it is advisable to switch to another supported template.
6. If you are using other language than English in the client area, note that some strings might be still in English, e.g. billing cycles or invoice status.
Note that this issue is not related to our module, but to WHMCS itself and we have no influence on these occurrences.
7. The available in the client area option "Add Funds", which allows adding extra cash reserve to the client balance (see: Client Area → Billing → Add Funds), is not supported by the Resellers Center module.
It is highly advised for the administrators to turn this option off to avoid errors: Admin Area → Genera Settings → Credit → Enable/Disable.
