Dual pricing and surcharges
Dual pricing or surcharge programYesSource: Helcim (opens in a new tab)Fee Saver is a credit card surcharge. Its terms say that in person it currently works only on the Helcim Smart Terminal (Helcim's help center also lists the newest card reader). Helcim can adjust the customer's fee for some card brand and cross-border costs, and can change, suspend or end Fee Saver at any time, with or without notice. Card network rules and state laws apply.YesSource: Square Support Center (opens in a new tab)Credit card surcharging, in open beta in the US: in person only, credit cards only, up to 3% and never above your cost of acceptance, and not available in Connecticut, Maine, Massachusetts or Puerto Rico. Square publishes no dual pricing program. In our estimate, card processing on in-person credit card sales costs your restaurant $0 with the surcharge and your customers pay it; debit and online sales keep Square's rate. In practice part of that cost stays with you: Square charges its fee on the whole sale, including tax and tip, tips can't be surcharged, and the 3% cap can fall below Square's fee on small tickets (2.6% + 15¢ is about 3.03% of a $35 ticket). Card network rules and state laws apply.
