I would like customers to be able to pay their invoices online. They receive their invoice by printed mail.
I need to add a surcharge to the invoice if they pay online.
So i need them to enter the amount of the invoice, and then I need to automatically add a service fee, to come to a total that they agree to pay via paypal.
How would I do this?

You can do this by (1) having a Number field on your form where users would enter their amount manually, (2) having a Form Calculation where you would calculate a total amount based on what they entered on the Number field, and then (3) pass this calculated amount to PayPal for payment.
Step 1: We add a Number field.
Step 2: We create a form calculation, and set it to calculate the number field plus our service fee.
Step 3: We pass the calculated total to the payment field:
