The short version
Pros: Cut card fees by 50–90%, boost cash flow. Cons: Guests hate it, compliance is tricky, and it can hurt sales volume. Only worth it if 30%+ of your payments are cash already.
The real math: how cash discounts work
You list "cash prices" on the menu, then add 3–4% for card payments. It's not a surcharge—it's a discount for cash. But guests see it as a fee either way.
- Typical savings: $500–$2K/month on $50K card volume at 2.5% fees.
- Break-even: Needs 20–30% cash adoption to offset any sales drop.
- POS setup: Most systems like Toast or Square support it, but you need clear signage.
Example: $100 check. Cash: $100. Card: $104. You save the $3 processor fee, but if the guest tips less or doesn't return, it's a net loss.

Cons that kill it for most operators
The drawbacks hit harder than the savings for many:
1. Guest backlash
- Feels like a hidden fee—reviews drop 10–20% in early months.
- Loses price-sensitive regulars to competitors.
- Confuses delivery/app orders where cash isn't an option.
2. Compliance and legal risks
- Illegal in CT, MA, ME—fines up to $500/transaction.
- Must disclose everywhere: menu, door, receipt.
- Tax implications: Discounts affect sales tax base.
3. Operational headaches
- More cash handling = theft risk and bank runs.
- Staff training on explanations and disputes.
- POS glitches or manual overrides eat time.

FAQs
What is a cash discount program for restaurants?
A cash discount program lists "cash prices" on your menu, then adds 3-4% for card payments. Legally it's framed as a discount for paying cash rather than a surcharge for cards. You're shifting the processing cost to the guest, saving yourself 2-3% on every card transaction.
Is a cash discount program legal for restaurants?
Yes in 47 states as of 2025. Connecticut, Massachusetts, and Maine prohibit them. You must clearly disclose the program with signage at the entrance, at the register, and on receipts. Mislabeling it as a "surcharge" instead of a "cash discount" can violate card network rules and state laws.
How much can a restaurant save with a cash discount program?
Typically $500-2,000/month on $50K in card volume, depending on your effective rate (usually 2-3%). You won't save on cash transactions—only on cards. If your customers are 90% card, you're passing the fee to 90% of guests, which creates friction even though savings are high.
Will customers get angry about cash discount programs?
Many will—reviews often drop 10-20% in the first few months. It feels like a hidden fee regardless of how you frame it. The program works best when you already have 30%+ cash customers or your guests are price-insensitive. Test signage and staff scripts carefully before full rollout.
