I understand, but we don’t have a product price. This is a form for Customers who have an invoice to pay to go and submit a payment. The Customer inputs the amount (price) they want to pay, specify an invoice number to apply it to, and we receive the payment and manually reconcile that.
So what we need is for the Plugin to have an option to markup the price by a percentage, like it’s able to currently do with Tax.
That said, on this page, it’s not currently calculating correctly using the tax option:theidealelectric.com/payment/
$100 x .029 = $2.90 // but the calculated result is $105.88
If you go through the transaction, the amount it says to pay Stripe is correct – 102.90
