Short answer: No, it does not.

Our fee is on top of any fees that your payment processor charges you.

However, in most cases, this is generally irrelevant as you only pay payment processing fees once, either on your gift voucher sale or when they come in and buy the product/service directly from you without a voucher. You never pay it twice in reality.

If you wish to pass on our fee to your customers, you can opt to do so.
