I'm looking for a script to allow customers in WHMCS to pay their bills in full. This is the page they will see :
(PM me for the link)
This page needs to lookup their IP address against the IP address in the WHMCS product database and display the balance due. Once the customer pays the total balance their service needs to be unsuspended and the payment needs to be marked off in WHMCS.
If their IP address is not in the WHMCS database then the customer needs to get a custom error page which we will provide.
If the customer is making a once off payment then they need to be charged an extra €5, otherwise their credit card details needs to be updated in the WHMCS database for future payments.
