2. 'Bill on Invoice Generate' - customer will receive invoice at the same time as the invoice for his hosting account.
3. 'Bill Each 1st Day of Month' - will generate invoices each first day of month.
4. 'Autogenerate Invoice' - this is important feature, if enabled, it will automatically send previously generated invoices directly to your customers.
5. 'Create Invoice Each' - when you set that field to e.g. '14' , all your customers will be billed exactly each 2 weeks after account creation.
6. 'Due Date' - the number of days in which your customers will have to pay the invoice.
7. 'Auto Apply Credits' - automatically apply any available credit when invoice is created.

1. 'Enable Credit Pay' - this option enables/disables credit billing for this module (if credit billing is enabled, standard billing will be turned off).

6. 'Due Date' - the number of days that your customers will have to pay the invoice.

If it is unmarked and credit balance reach 0, account will not be suspended and invoice will be generated according to number of days set in 'Create Invoices Each' field.

Here you can set Application Manager (Softaculous/Installatron) and cPanel theme. Default value of theme is 'x3' .
To use different theme you have installed simply enter its name as shown on the screen below.

'Free Limit' field is used to set amount of usage records for which customer won't be charged.
In our example, customer won't be charged for 1GB (1024MB) bandwidth.
'Price' defines how much your client will have to pay for specyfic resource. Note that we provide two types of charging: units per hour and units used since last cron run.
For example, user pays for subdomain quantity each hour, but when he generates traffic, he will pay only once for bandwith he used since last cron run.
'Displayed Unit' category defines how record usage will be displayed. It do not affect free limit and pricing, they are calculated in basic unit.
So, if you select 'GB' , free limit will be still 1024 MB, and price will be MB/hr, not GB/hr.
'Status' allows you to enable/disable billing for this resource.
To proceed, choose your usage records, units, status, set up the prices and free limits. Afterwards, press 'Save Changes' .

Each cron run will create an item for each customer if it does not exist at the moment and add new records to existing ones.

You can enable hourly billing for any product type.
Regardless of whether it is a server, web hosting account or other, customer will be billed for each hour of using the product.

As in the case of hourly billing, you can enable ticket billing for any product type.

1. Go to 'Addons' → 'Advanced Billing 2.0.1' and select your product from 'Enable Advanced Billing 2.0 for:' .

Afterwards, enter '1' into 'Create Invoices Each ', ' 20' into 'Minimal Credit' and '50' into 'Low Credit Notify' .
With these settings your client will be billed from credit balance as soon as payment for resource usage reach 20$.
He will also recive email if his credit balance fall below 50$.
