Dual pricing vs cash discount vs surcharge: what's the difference?
All three let a business pass along card fees instead of absorbing them, and all three are legal in Washington, NWPB's market. Surcharge legality varies by state, so if you operate outside Washington, check your own state's rules before you set one up (Washington's rules are here for reference). The difference between the three is which cards each one covers and how the price is framed. Dual pricing posts two prices up front and covers every card, including debit. “Cash discount” is the older name for the same goal, and we install it as dual pricing so it gets that same coverage. Surcharging keeps one price and adds a disclosed, capped fee only on credit cards.
Dual pricing: two prices, every card
Dual pricing posts a cash price and a card price on the shelf, the menu, or the invoice, before the customer pays. The customer picks. Because the two prices are posted rather than added at the register, the program covers every card type, including debit, which is the one card surcharging can never touch. That makes dual pricing the fit for businesses with a lot of debit or mixed-card counter traffic, like retail and food service.
The tradeoff is visibility: both prices are on display everywhere, all the time, so signage and menu design matter more than with a surcharge.
Cash discount: the same goal, installed as dual pricing
“Cash discount” is the older name for this idea: post the card price, then knock a discount off it for cash. Done that way, it's compliant. What gets flagged is a different setup a lot of providers switched to: post the lower cash price instead, then add a fee for cards at the register. Customers get surprised at the point of sale, and card brands flag programs built that way. We install a cash discount request as dual pricing so there's no ambiguity either way: both prices, cash and card, posted before the sale. The savings a customer was searching for under “cash discount” are the same savings dual pricing delivers, just built the way the card networks accept.
Surcharging: one price, a capped fee on credit only
Surcharging keeps a single posted price and adds a disclosed fee only when the customer pays with credit. The fee can never exceed the actual cost of accepting the card, and it is capped at the network limit regardless: Visa caps credit surcharges at 3%, Mastercard at 4%. Debit and prepaid cards can never be surcharged, full stop, even if the terminal reads the card as credit. That is the rule most DIY setups get wrong. Surcharging fits best where credit is most of the volume, like B2B and professional services. See the Washington surcharge rules for the full compliance list: capped, disclosed before payment, and itemized on the receipt.
The compliance basics that apply across all three
Debit is protected
No program can add a fee to a debit or prepaid transaction. Only dual pricing's two-price structure reaches debit at all, and it does so by posting the price, not adding a fee.
Disclosure comes before payment
Every model requires the customer to see the pricing or the fee before they commit. Dual pricing and a cash discount request satisfy that with a posted sign, a menu, or a screen prompt at the terminal, since both prices are already on display. Surcharging has a stricter bar: [Washington rules](/washington-surcharge-laws) require a posted notice at the entrance and another at the point of sale before payment, plus the receipt line item. One terminal prompt alone doesn't satisfy it.
The receipt has to show it
Surcharges are itemized as their own line. Dual pricing, including a cash discount request (which we install as dual pricing), shows the price the customer chose. None of the three can bury the number after the fact.
The cap is real
A surcharge above the network limit or above your actual cost is a compliance problem, not a pricing choice. Terminals should be configured to hold the cap automatically.

Fair questions
What's the simplest way to tell dual pricing, cash discount, and surcharge apart?
Look at what's posted and what's covered. Dual pricing shows two prices for every item before the sale and applies to all cards, debit included. “Cash discount” is the older name merchants search for the same idea; we set it up as dual pricing, so it works the same way. Surcharging shows one price and adds a disclosed, capped fee only when a credit card is used; debit is never touched.
Which one covers debit cards?
Dual pricing, which is also how we install a cash discount request. Network rules ban surcharging debit and prepaid cards outright, even if the terminal reads them as credit, so surcharging never reaches debit. If debit is a big share of your volume, dual pricing (whether you call it that or ask for a cash discount) is the one built to reach it.
Is a credit card surcharge legal in Washington?
Yes. Washington has no state law against it, and the card networks allow it under their own rules: credit cards only, capped at the network limit, disclosed before payment, and itemized on the receipt. See the full Washington surcharge rules for the current details.
How much can each program actually save a business?
It depends on your card mix and ticket size, but the pattern is consistent: businesses that switch keep real money that used to go straight to card fees. Send a recent statement for a free rate analysis and get your specific number instead of a guess.
Which one is right for my business?
Mostly card mix and counter style. Heavy debit or grocery/retail traffic tends to fit dual pricing. B2B and professional services with mostly credit volume tend to fit surcharging. If you came looking for a cash discount, dual pricing is what we install for it, so it fits the same businesses dual pricing does. A free rate analysis settles it against your real numbers.
Can I switch from one model to another later?
Yes. None of these lock you in permanently, though switching means new signage, new receipt language, and a terminal reconfiguration. Most businesses pick once after reviewing their statement rather than trial-and-error at the register.
