What is surcharging?
Adding a fee on top of the price when a customer pays with a credit card. It is regulated by state law and by the card brands: it is capped, it must be disclosed, it can only apply to credit (never debit), and it must be registered with the networks.
What is dual pricing?
Showing two prices: a cash (or ACH) price and a card price. The customer picks. Because you are offering a discount for one method rather than adding a fee for another, it is treated differently by the card brands and is generally easier to run correctly.
Is surcharging legal in Arizona?
Arizona does not ban credit-card surcharges, but the card-brand rules still apply: registration, disclosure at the entrance and point of sale, a cap on the amount, and no surcharging on debit or prepaid cards. Getting any of that wrong is a compliance problem.
Is dual pricing legal in Arizona?
Yes. Dual pricing and cash discounting are permitted, and they avoid most of the surcharge-specific rules because the card price is simply the listed price.
Which one should a small business use?
For most Arizona businesses, dual pricing. It is simpler, it applies cleanly to debit and ACH, and it does not require network registration. Surcharging makes sense mainly for businesses that want a single price and only take credit cards.
How is dual pricing displayed?
Both prices on the menu, quote, or invoice, with the payment method clearly labeled. Your terminal or invoice software should do the math automatically so staff never have to explain it.

A worked example on a $500 invoice
Surcharging: the invoice says $500, and a 3% surcharge is added only if the customer pays with a credit card: $515. Debit and cash must stay at $500, and the surcharge cannot exceed your actual cost or the network cap.
Dual pricing: the invoice shows a cash/ACH price of $500 and a card price of $515. The customer picks. There is no "fee," just two prices, which is why it is simpler to stay compliant.
The customer pays the same $515 either way; the difference is the rules you have to follow to get there.
Mistakes that create real risk
- Surcharging a debit card (not allowed under network rules)
- Not posting the required disclosure at the entrance and the point of sale
- Setting a surcharge higher than your actual cost
- Calling it a "convenience fee" or "service fee" when it is really a card surcharge
- Applying the card price only after the customer has chosen to pay
What good disclosure looks like
Both prices visible before the customer decides, the payment method named plainly, and the same rule applied to everyone. Your invoicing software should print it automatically so nobody has to remember.
The short version
Both are legal in Arizona if done correctly. Dual pricing is simpler, works with debit and ACH, and skips network registration. For most small businesses it is the better choice.
