Adds surcharges and extra fees as named lines, online, at the till and on draft orders.

The problem

Wharfage keeps your fee rules: fixed or percentage, on the whole order or on tagged products, by channel, payment kind, order size, country and state.

The two incumbents carry 328 reviews between them (re-opened 2026-10-16: Upcharge Surcharge Fee Tariff, 4.7 stars from 197, Basic $9.99/mo with payment- and shipping-method fees on a $29.99 Plus plan; Magical Surcharge + Extra Fees, 4.9 stars from 131, $9/mo). Neither page says a word about draft orders or the card-surcharge rules. Wharfage's pitch: one price, the same fees on all three ways an order is made, a card fee that cannot quietly break the card rules, and a list of the orders where a fee was missed or doubled.

• adds each fee as its own named line, with its working, online, on the till (POS) and on the orders staff type up (draft orders);
• checks every card fee against the rules a shop gets fined for: at most 3%, credit cards only (never debit or prepaid), not to buyers in Connecticut or Massachusetts, and named to the buyer before they pay;
• checks the rules against each other and the catalog: a fee on a tag no product carries, two fees under one name on the same product, a fee bigger than the item, a fee with no name for the buyer;
