Restaurant Payment Processing Explained (2026)
Every time a card runs at your register, three companies take a slice. Here's who gets paid, and why.
Most restaurant operators pay 2–3% on every card sale without ever understanding what that fee actually buys. Below is the plain-English version: who gets paid, why, and how a cash discount program works.

1. The three-party split: interchange, assessments, markup
When a customer pays with a card, your processing fee splits across three places:
- Interchange (~70–80% of the fee): paid to the cardholder's bank (the bank that issued their Visa or Mastercard). Set by the card networks; non-negotiable for merchants. Varies by card type — basic debit is cheapest, rewards/corporate cards are most expensive.
- Assessments (~5–10%): paid to the card networks themselves (Visa, Mastercard, Discover, Amex). Set by the networks; non-negotiable.
- Markup (~10–25%): paid to your processor (Square, Toast, Clover, PalomaPOS, etc.). This is the only part that's negotiable.
When you "negotiate a lower rate," you're negotiating the markup. Interchange and assessments are fixed.
2. Two pricing models: flat-rate vs interchange-plus
Flat-rate (Square, Stripe, PayPal): one rate regardless of card type. Simple. Predictable. Usually the most expensive at scale.
Interchange-plus (most merchant accounts): you pay actual interchange + assessments + a fixed processor markup. Typical: ~0.20% + $0.10 over interchange. More transparent. Cheaper above ~$15K/month in card volume.
Most U.S. food businesses doing more than $20K/month in card sales save money on interchange-plus.
3. How a cash discount program works
With a cash discount program, your posted menu price is the card price, and guests who pay cash receive a discount at the register. Card-network and state rules on signage and pricing apply, and we review them with you before you turn it on.
4. The fees you didn't know you were paying
Beyond the percentage and per-swipe fee, your statement may include:
- PCI compliance fee ($5–$25/mo)
- Statement fee ($5–$15/mo)
- Batch fee ($0.20–$0.30/day)
- Non-qualified tier surcharge (0.5%–2% on certain card types)
- Chargeback fee ($15–$25 per dispute)
- Early-termination fee ($300–$500+)
Ask any provider for a written quote that lists every one of these. PalomaPOS quotes processing from your current statement — see /pricing.
5. Funding speed: when does the money actually arrive?
"Settlement" (the network → processor step) takes 1–2 business days. "Funding" (processor → your bank) is the controllable part:
- Same-day funding: PalomaPOS includes it, with an instant funding option; some providers charge extra for faster transfers
- Next business day: many merchant accounts
- 2–3 business days: most legacy POS without explicit fast-funding setup
For food trucks and cafés running on tight cash flow, funding speed often matters more than the processing rate.
Bottom line
Restaurant payment processing in 2026 has three levers you can actually move: pricing model (flat-rate vs interchange-plus), Cash Discount enablement, and funding speed. Pull all three and your effective cost drops dramatically — often by $1,000+/month for a typical operator.

FAQ
What's the difference between flat-rate and interchange-plus pricing?
Flat-rate pricing charges the same regardless of card type — simpler but more expensive at volume. Interchange-plus charges actual interchange + a fixed markup — more transparent and typically cheaper for restaurants over ~$15K/month in card volume.
Is interchange-plus always cheaper?
Usually yes for U.S. restaurants over $15K–$20K/month in card sales. Below that volume, the simplicity of flat-rate may not be worth the savings. Start by checking your effective rate with our calculator.
What's the lowest possible processing rate I can pay?
Your rate depends on card mix, ticket size, and pricing model — compare written quotes on your effective rate. A cash discount program is another option: the posted price is the card price, and guests who pay cash get a discount.
Why do my fees go up some months even though my sales don't?
Two common causes: card mix shifted toward more rewards/corporate cards (higher interchange), or you got hit with a non-qualified tier surcharge. Pull a recent statement and look at the 'non-qualified' line item.
