The short answer
A cash discount program is a pricing model where your posted/menu prices are the "credit-card price," and you offer a discount (typically 3-4%) to customers who pay with cash or PIN-debit. Economically, the customer paying with credit is absorbing your processing fees; legally, the model is a posted price with a discount for non-card payment, not a surcharge on card payment. That legal distinction matters because cash discount programs are not subject to the Visa/Mastercard 4% surcharge cap, the state-level surcharge bans in CT/MA/ME, or the card-brand registration requirement.
How it differs from surcharging
- Surcharge program: Posted price is the base price; customers paying credit see a line-item surcharge added at checkout. Capped at 4% or cost. Requires card-brand registration. Restricted in some states.
- Cash discount program: Posted price is the credit-card price; customers paying cash see a line-item discount subtracted at checkout. Not capped. No registration. Legal in all 50 states.
- Dual pricing: Two prices posted side-by-side (cash price and credit price). A hybrid with elements of both.
What operators need to know
- Posted prices must reflect the credit-card price. The IRS/FTC and most state AGs require that the advertised price be what credit-card customers actually pay. You can't quote $20 in advertising, charge $20.60 on credit, and call it a cash discount — that's deceptive pricing.
- Clear disclosure is still required. Sign on the door, sign at the register, notice online at checkout. The customer needs to know in advance that cash payment earns a discount.
- Receipts must show the discount as a separate line. Not bundled into the subtotal, not disguised as a "service adjustment." Your POS or e-commerce platform must support a separate discount line.
- Online implementation is harder than retail. Retail: one price on the menu, discount at the register. Online: every product page shows credit-card price; cash payment method requires a dedicated flow (usually ACH, Zelle, or wire). For e-commerce, dual pricing is usually a cleaner UX than cash discount.
- Debit treatment varies. The networks require you to include PIN-debit in the "cash" side (debit cards get the discount). Signature-debit rules are murky — most compliant programs include both.
Economics in practice
On a $100 sale at a merchant with 3% effective processing cost:
- Surcharging: Customer pays $103 on credit, $100 on cash. Merchant nets $100 either way (3% surcharge covers 3% processing). Capped at 4% max.
- Cash discount: Customer pays $100 on credit, $96.25 on cash (≈ 3.75% discount). Merchant nets $97 on credit, $96.25 on cash. Slightly worse on credit, slightly better on cash — but the 4% cap doesn't apply so you can target true-cost recovery.
When cash discount makes sense
- Card-present retail + restaurants. The channel where customers expect posted prices and discounts, and where cash remains viable.
- B2B payments with ACH as an option. ACH is the "cash" side; credit-card customers pay the posted price.
- High-risk verticals where surcharging is awkward. Peptides, kratom, and other reserve-heavy categories often benefit from the more flexible pricing structure.
When it doesn't
For typical consumer e-commerce, a cash-payment flow is rare and awkward. Most operators who want fee recovery online should use dual pricing or the checkout-native surcharge flow instead. See also zero-fee processing.
