Processing is one of the biggest line items most restaurants never audit. Here’s how card fees actually work — and where the padding hides.
July 13, 2026
Ask ten operators what they pay to accept cards and most will quote the headline rate from their processor’s website. Almost none can say what actually left the bank account last month. That gap is where processors make their money. For a restaurant doing solid volume, card processing is routinely a top-five expense — bigger than the software line on your POS bill, often bigger than repairs and marketing combined — and it’s the one big cost most owners have never audited line by line. The fees hide in plain sight: a statement written in industry jargon, a “rate” that only applies to some transactions, and a stack of monthly extras nobody mentioned at signup. This guide walks through how card fees actually work, the three pricing models you’ll be offered, and how to find out what you’re really paying.
Every card transaction splits its fee three ways. Interchange goes to the bank that issued the customer’s card — it’s set by the card networks, published openly, and varies by card type: a basic debit card costs far less to accept than a premium travel-rewards credit card. Across a typical restaurant mix, interchange lands somewhere in the range of roughly 1.5% to 2.5% of the sale. Assessments are a much smaller slice that goes to the networks themselves — Visa, Mastercard, and the rest. Everything above those two layers is processor markup: the only negotiable part, and the only part that differs between providers. When two processors quote you different “rates,” interchange and assessments are identical for both — you’re comparing markups, whether the quote makes that visible or not.
Processors package those layers in three main ways, and the packaging matters more than the headline number.
| Pricing model | How it works | Watch out for |
|---|---|---|
| Flat rate | One blended rate for every card, e.g. a fixed percentage plus a small per-transaction fee | Simple to predict, but you overpay on debit and other low-interchange cards — the flat rate is set high enough to cover the expensive ones |
| Interchange-plus | You pay actual interchange at cost, plus a disclosed markup | Usually the cheapest at volume; the statement is longer and takes more effort to read |
| Tiered / bundled | Transactions are sorted into “qualified,” “mid-qualified,” and “non-qualified” buckets at different rates | The processor decides which bucket each sale lands in — quoted rates apply to the cheapest bucket, real cards mostly land in the dearer ones |
As a rule of thumb: flat rate suits low or seasonal volume where predictability beats optimization; interchange-plus tends to win once volume is steady; tiered pricing is hard to audit by design and is the model most worth walking away from. Whatever you choose, get the markup in writing, separately from interchange — that single demand tells you a lot about the processor you’re dealing with.
The percentage is only part of the bill. Statements pad out with fixed and semi-hidden charges that add up fast at restaurant ticket sizes:
Not every transaction costs the same. A card tapped or dipped at the counter is card-present: lower fraud risk, lower interchange. An order typed into a website is card-not-present and prices higher — that’s the network’s rule, not your processor being greedy. This is worth knowing when you look at your channel mix, but keep it in perspective: the difference between card-present and online interchange is a fraction of a percent, while a third-party delivery marketplace takes a double-digit commission on the same order. Moving guests from marketplaces to commission-free direct online ordering saves you the commission and costs you only the card-not-present premium — the math, worked through properly, is in our delivery commission breakdown.
The pattern is consistent. A restaurant signs up at a promotional rate, the rate creeps upward through “notice of fee adjustment” inserts nobody reads, and new junk fees appear over time. Nobody reconciles the statement because it’s twelve pages of codes. Meanwhile the processor is a separate vendor from the POS company, so when a terminal drops a payment or a deposit goes missing, each side points at the other — and you’re the one on hold. Separate processing also means separate reporting: your POS says one number, your processor deposits another, and someone has to reconcile tips, refunds, and batches between them every week. The overpayment isn’t only the rate — it’s the hours.
Passing fees to guests is increasingly common, but it’s regulated. Surcharging credit cards is permitted in most US states and, since the card-network settlements, in most of Canada — Quebec is the notable exception — and the networks cap how much you can add and require disclosure before payment. Debit cards generally can’t be surcharged at all. Cash discounting — posting card prices and discounting for cash — is the alternative many operators prefer for guest experience. Rules change and vary by province and state, so verify the current card-network requirements and local law before posting signage (this reflects publicly available information as of 2026 — confirm with your processor). And weigh the guest-experience cost honestly: a 3% line at the bottom of a date-night check has a way of showing up in the tip and the review.
Novaryq bundles payments into the platform rather than bolting on a third-party processor, which changes the experience in three ways. Reconciliation disappears — sales, tips, refunds, and deposits live in the same system that rang the order, so the numbers match by construction. Accountability is single-source: one support line owns the terminal, the software, and the money. And the bill is one bill — transparent pricing, a month-to-month option, and no per-order commission on direct online orders, for restaurants in both the US and Canada. However you take payments, the advice above stands: know your effective rate, get markups in writing, and audit the statement once a quarter. It’s an hour of work that tends to pay better than most shifts.
Most restaurants land somewhere between roughly 2% and 3.5% per transaction once all fees are counted, depending on card mix, channel (card-present vs online), and pricing model. The more useful number is your own effective rate: total monthly processing cost divided by total card sales.
Interchange is set by the card networks and paid to the customer’s bank — every processor pays the same rates. Markup is what the processor adds on top, and it’s the only part you can negotiate. Interchange-plus pricing shows the two separately; flat and tiered pricing blend them together.
Often, yes — via a credit card surcharge or a cash discount program. Surcharging is allowed in most US states and most of Canada excluding Quebec, with network caps and disclosure requirements, and debit generally cannot be surcharged. Rules change, so confirm current network and local requirements first.
Card-not-present transactions carry higher fraud risk, so the networks price their interchange higher. The premium is small — a fraction of a percent — which is why direct online ordering still beats third-party marketplaces that charge double-digit commissions on the same order.
