Our fee is listed in the Merchant Agreement that is signed upon applying with Sezzle. If for some reason a different fee rate applies to your store, our approvals team will let you know your specific rate. Our fee covers all fraud and repayment risk, as well as the cost of processing all four installments for the shopper.
You can see the fee that has been deducted from your orders right on the "Orders" page - it's clearly shown on all orders. We automatically deduct the fee when we process the order, so you never have to worry about paying us back or sending in a bill at the end of the month!
