Payment processing in South Dakota.
VitaPay serves merchants in South Dakota, as it does in every US state. Below is a plain guide to how a cash discount and a surcharge differ, and how South Dakota treats surcharges, plus the official offices worth knowing before you take your first card payment there: the sales-tax agency and where the business is registered.
How the rules differ in South Dakota.
A cash discount and a surcharge are not the same thing. With a cash discount, the posted price is the card price, and customers who pay cash get a discount from it. With a surcharge, an extra amount is added on top of the posted price when a customer pays by card. State rules and card-network rules treat the two differently.
