In this section we will present to you a sample workflow of the module.

In a basic workflow 3 characters take part:
Provider – a person with Domains Reseller For WHMCS installed in their system.
Reseller - a person with a client account in the provider's WHMCS system.
Additionally, the reseller has its own system with registrar generated by Domains Reseller For WHMCS.
End-Customer – a person with a client account in the Reseller's system.

Additionally, there also must be a product, which in this case will be domain '' .

Provider Part
Let's start from the beginning. Provider installs Domains Reseller For WHMCS in the system.
He or she already has a few TLDs in the offer and wishes to allow the reseller to offer them from their systems.
Now, the provider configures Domains Reseller For WHMCS through enabling its API and enabling .com TLD for API.
Afterwards, he or she proceeds to API Users, enables Reseller and generates API key for them.
Additionally, he or she assigns a 10% discount for Reseller under API Users tab.
From this moment, Reseller is able to access API details from the client account in the Reseller area.
Additionally, he or she receives an email form the Provider with registrar module and instruction on how to install it .
Reseller installs the registrar in the system according to the instruction received.
He or she also sets up .com TLD in the system and assigns the previously installed registrar to it.
Now, there is one step that separates them from offering the domain from their system.
Reseller top-up his credit balance in the provider system.
Provider creates an invoice for the Reseller, the Reseller pays the invoice and then again the Provider manually adds the same amount to Reseller's credit balance.
Form now on, any .com domain can be ordered.
End-Customer orders '' domain from his or her client area in the Reseller system.
They are now able to fully manage the domain.

Last Word About Payment
Payment goes to the Reseller while, during registration process, credits from Reseller balance are withdrawn.
It is worth mentioning that the amount a customer paid is defined by a Reseller.
Credits withdrawn are equal to a domain price in the Provider system minus the promocode assigned to the Reseller.

Extended TLDs Management - Integration With Domain Orders Extended For WHMCS

Domain Orders Extended For WHMCS allows quick and easy management of multiple TLDs and lets you offer these TLDs to your resellers at hand!
In this part we are going to present how fluently these two modules may work together to let you gain the most from the integration.
Open your Domain Orders Extended For WHMCS addon module, move to 'Predefined TLD Sets' section and install one of the TLD groups of your wish.
DR 54 1.png
Come back to the 'TLDs Configuration', find your group with newly assigned TLDs and define pricing for each of them. To make it faster, select all TLDs and use a mass action button.
DR 54 2.png
It is time to set up the pricing. Save the changes once ready.

You can find more information about the pricing in Domain Orders Extended For WHMCS here.

DR 54 3.png
Select all TLDs the same way you did earlier and 'Edit TLDs Configuration'.

There, find 'Overwrite Registrar' option and toggle it. A dropdown menu with available registrars will appear. Select the one used in Domains Reseller module.

DR 54 4.png
It is time to go back to 'Domains Reseller' module. Move to the 'Configuration' section to enable the previously configured TLDs.

Your TLDs are now ready to be offered by your resellers.

DR 54 5.png
Your resellers, who also own Domain Orders Extended For WHMCS, can quickly update their offer by installing the very same gTLD category.

The next steps are exactly the same as those you have just performed: setting up the pricing and assigning the TLDs to the Domains Reseller For WHMCS registrar module generated by you.

DR 54 6.png
Most importantly, the offer can be now extremely client-friendly due to a high range of selection of Domain Orders Extended domain registration forms including:
  • Lagom theme
  • General Category View
  • Multi Category View
  • List View
DR 54 7.png
There is surely a solution for resellers who do not own Domain Orders Extended module yet.

They will simply have to add and set up each TLD separately at the 'Setup' 'Products/Services' 'Domain Pricing', which may be time consuming.
That is why we highly recommend using the modules together to manage your time optimally.

DR 54 8.png
As you can see, integrating of Domains Resellers For WHMCS with Domain Orders Extended For WHMCS allows you to offer vast array of TLDs with ease.

A win-win situation with benefits for all: you expanding and perfecting your offer, your resellers managing the TLDs and surely for the end-clients enjoying the final outcomes!

Simply generate the module with the same name and save what you forgot to save the last time.

2. If your reseller gets an error 'Unable to register domain, please contact administration (license problem).' , that means your license is invalid or expired.
DR 55.png
