Gateway fees module

[AffordableDomainsCanada]

So ive come across this module that is open source and thought I would share it and if anyone can improve the code that would be awesome!

 

[h=1]Gateway Fees Plugin for WHMCS[/h] Version: 1.0.1

This is an open-source version of the Gateway Fees plugin for WHMCS, it will allow you to set percentage fees on prices of your product in WHMCS.

To install this addon module, upload the gateway_fees directory to /modules/addons/.

Go to Setup -> Addon Modules, active and configure price ($ and/or % per transaction).

Your activated payment gateways will be automaticly shown there. You can set fixed fee or/and some percent of the total.
