A cash discount program lets a business recover some or all of its card processing costs by giving customers who pay with cash a lower price. Done right, it can cut processing costs a lot. Done wrong, it can break card brand rules or California's pricing laws.
The terms get mixed up constantly, including by the people selling these programs, so let me start with what each one actually means.
Cash discount vs dual pricing vs surcharging
The difference is not just wording. A discount lowers the price customers saw. A surcharge raises it. That direction matters for both the card brand rules and California law.
- Cash discount: your posted price is the regular price, and customers who pay with cash (or another non-card method) get a discount off it.
- Dual pricing: you show two prices side by side, a card price and a cash price, so customers see both before they decide how to pay. It is really a cash discount made fully visible.
- Surcharging: your posted price is the base price, and a fee is added when a customer pays with a credit card.
How a cash discount program works at the register
Your prices are set to cover the cost of card acceptance. Signs at the entrance and the register tell customers that a discount applies when they pay with cash.
When a customer pays with a card, they pay the posted price. When they pay with cash, the POS takes the discount off and the receipt shows it. Because most customers still pay by card, the posted price does the work of covering your processing costs.
With dual pricing, menus, shelf tags, and the screen show both numbers, and the receipt shows which one the customer paid. Your POS has to be configured to calculate both correctly, including tax and tips.
The trap: a "discount" that is really a surcharge
Some programs post the lower cash price on the shelf and then add a fee at the register for card payments, labeled something like a non-cash adjustment or service fee. Whatever the receipt calls it, a charge added on top of the posted price for paying by card works like a surcharge.
That matters because surcharges come with their own rules. The card brands do not allow surcharging debit or prepaid cards, and they have caps, notice, and disclosure requirements. A program that adds the same fee to every card, debit included, can put your account at risk.
What the card brands allow
Federal law protects a business's right to offer a discount for paying with cash, checks, debit cards, or credit cards, and the card networks cannot stop you from doing it (15 U.S.C. 1693o-2). A true cash discount is the simplest option from a card rules point of view.
Surcharging is more restricted. Visa's U.S. rules, for example:
- Allow a surcharge on credit cards only, never on debit or prepaid cards.
- Cap the surcharge at the lower of your actual cost of accepting the card or 3%.
- Require you to notify your processor at least 30 days before you start.
- Require signs at the point of entry and point of sale, and the surcharge shown as a separate line on the receipt.
Other card brands have their own rules and caps, and card brand rules have been changing. Confirm the current limits with your processor before you set a surcharge.
California rules for cash discounts
California Civil Code section 1748.1 specifically allows businesses to offer discounts for cash. According to the California Attorney General, a discount for paying by cash, check, or debit has to be available to all customers, and businesses cannot mislead customers by advertising a lower price than they actually charge.
Since July 1, 2024, California's hidden fees law (SB 478) has required advertised prices to include all mandatory fees. The Attorney General's guidance says a card processing fee is generally not mandatory if the customer can avoid it by paying another way, such as cash. But if a business accepts only cards, the fee is mandatory and has to be built into the advertised price.
A true cash discount fits these rules well, because the price customers see is the most they will pay. I cover the surcharging side, the restaurant exception, and the details of SB 478 in my California surcharging and dual pricing guide (listed below under More guides).
Pros and cons
- Pro: it can offset a large share of your processing costs.
- Pro: with a true discount or dual pricing, customers never pay more than the price they were shown.
- Pro: it covers debit card payments too, because the card price simply applies to every card. A surcharge cannot be added to debit.
- Con: your posted prices go up, which customers comparing you to a competitor will notice.
- Con: signs, menus, receipts, and your POS all have to be set up correctly and kept that way.
- Con: tips, refunds, and partial payments need careful handling so the numbers stay right.
How customers react
What tends to bother customers is not the price itself but surprise: a fee they did not see until the receipt. Clear signs, a short line on the menu, and staff who can explain it in one sentence go a long way.
Some owners keep things simple by building the card price into everything and simply offering cash customers a little off. Others prefer showing both prices so nothing feels hidden. Both can work.
Who a cash discount program fits
It tends to fit businesses with thin margins and steady card volume: restaurants, auto repair, salons, and many service businesses. It is a harder sell for businesses competing mainly on posted price, or where customers rarely carry cash.
