Paystack/WHMCS Integration

[naijagene]

Problem/Motivation

Unable to pass the payment charges to the customer

Proposed resolution

The plugin is working perfectly on our whmcs app, but as an average programmer, i don't know what needs to be done to ensure that at the point of checking out, the system calculates the total charges of paystack and ad it to the total amount due

I wouldn't mind a step by step guide to assist me to resolve this issue
