No it does not. Our fee is on top of any fees that your payment processor (PayPal/Stripe etc...) charges.
We recommend using Square or Stripe as your main payment processor as the customer experience is the best, and most customers have a credit/debit card, whilst only some customers have a PayPal account.
How to pass fees onto your customers
If you wish to pass on our fee to your customers, you can opt to do so.
