We need to integrate the norwegian payment gateway BBS with WHMCS ([url removed, login to view]).

The docs for creating a payment gateway with whmcs can be found at [url removed, login to view]
The docs for the BBS gateway can be found at [url removed, login to view]
We will provide you with a fully setup whmcs system to test with and a test account with the BBS gateway.
