The amounts are calculated based on the US Stripe fee of 2.9% + $0.30 per transaction. Unlike other invoice solutions, Indy Invoices doesn't charge additional fees on top of those from the payment processor.
When you know the total amount you’ll be receiving, simply put it into the calculator to determine how much the online transaction processing fee will be should you use Stripe.
We take your original invoice total and add in the US Stripe processing fee (2.9% + $0.30 per transaction). If you choose to have your client cover the cost of this processing fee, this number reflects the total amount you should invoice.
