I like your Payment Gateway Charges For WHMCS Module, but I have a feature request and hope that this will be implemented.
Actually the client see on the Checkout Page only the Box like "Paypal 2,5% + 0,50 USD". The amount of the payment fee will be shown on the invoice, after he has submitted the order. The client would have to calculate the amount itself, to see what he has to pay total (cost of the product + fee). That's not fair.
In some countries it is even rule that the customer must see the amount of the fee during the checkout and not only after submitting the order.
Can you make an option that the Customer can see the amount of the Fee on the checkout page, so that the amount is displayed in the pricing table on the checkoutpage and that the amount is added in the "Total Due Today", Just as it makes the module on the bill already.
This is better for the customer and also meets the requirements in some countries.
Thanks.
