Arrêtez de payer trop cher pour le traitement des paiements – Réduisez vos coûts de 20 % ou plus

Most business owners I talk to know they pay too much for card processing. What they don't know is how much, or where it's going. Processor statements aren't written to make that easy.

I've spent more than 15 years in banking and payments, and the pattern hasn't changed. The rate you were quoted and the rate you actually pay are two different numbers. This guide shows you how to find the real one and what to do about it.

You're Probably Paying Too Much. Here's the Proof.

Card fees keep climbing. According to the Merchants Payments Coalition, citing Nilson Report data, U.S. merchants paid $198.25 billion in credit and debit card fees in 2025, up 5.9 percent from 2024. The average Visa and Mastercard credit card rate rose to 2.36 percent, up from 2.02 percent in 2010.

That's the average. Many small businesses on flat-rate plans pay 2.9 percent or more on every sale, no matter what card the customer uses. The difference between what the card actually costs and what you pay is your processor's margin.

Merchants are pushing back. J.D. Power's 2026 U.S. Merchant Services Satisfaction Study found 35 percent of small businesses now surcharge credit cards. But 32 percent of merchants say customers sometimes walk away when a surcharge is added. Before you pass the cost on, make sure it's the right cost.

What Card Processing Actually Costs in 2026

Every card transaction has three layers of cost. Your processor only controls one of them.

Interchange. Set by Visa and Mastercard and paid to the bank that issued the card. Consumer credit cards often run about 1.5 to 2.5 percent, depending on the card. Debit cards from large banks are capped at 21 cents plus 0.05 percent, plus a 1 cent fraud adjustment. Not negotiable.

Network fees. Assessments and per-item fees paid to the card brands, usually around 0.13 to 0.15 percent plus small fixed fees. Not negotiable.

Processor markup. Anywhere from about 0.15 percent to well over 1 percent, plus monthly and per-item fees. This is the only layer you can negotiate.

Here's what a 0.7 point gap between a 2.9 percent flat rate and a 2.2 percent effective rate looks like:

Your actual gap depends on your card mix and average ticket. But at $100,000 a month, $8,400 a year is real money, and it comes straight off your bottom line.

How to Calculate Your Real Processing Cost

Pull your last three months of statements. For each month, run this formula:

Then sort your fees into buckets: interchange, network fees, processor markup, per-item fees, and monthly or annual fees like PCI, gateway, terminal, and statement fees. If your effective rate is above 2.5 percent, there's likely money to recover. Above 3 percent, have the conversation this week.

Flat Rate vs. Interchange-Plus: Which Fits You?

Flat-rate pricing is simple. Interchange-plus is transparent. Here's a rough guide by volume:

Here's why. On a 2.9 percent flat rate, you pay the same on a $50 debit sale that really costs about half a percent as you do on a premium rewards card that costs more than 2 percent. Your debit customers are covering your processor's margin on the expensive cards. With interchange-plus, each transaction costs what it actually costs, plus a markup you can see. IntelliPay's interchange-plus pricing shows every fee on every transaction.

The Hidden Fees Draining Your Business

Most merchants watch the percentage and miss the fixed fees. These are the ones I see most often.

The "free" terminal. A terminal typically costs $150 to $300. When a processor gives you one free, it often gets paid back through a higher rate. An extra 0.10 to 0.15 percent on $40,000 a month is $40 to $60 a month, or $1,440 to $2,160 over three years. Buy your own equipment and negotiate a rate without the subsidy.

Terminal leases. A terminal you could buy for $300 can cost thousands over a non-cancelable lease, and you still don't own it at the end. Read the lease before you sign, or skip it.

Chargeback fees. Most processors charge $15 to $25 per chargeback, and high-risk accounts often pay more. That's on top of losing the sale.

Slow funding. If your deposits take two or three days, that's your cash sitting in someone else's account. Ask how fast you're funded and what next-day funding costs.

Monthly and annual fees to check:

Statement fees, often $5 to $15 a month

Gateway fees, often $10 to $25 a month

Batch fees, often $0.05 to $0.15 per batch

PCI compliance or non-compliance fees

Annual fees and vaguely labeled "regulatory" or "network" fees that aren't in your contract

Six Ways to Cut Your Processing Costs

1. Switch to Interchange-Plus Pricing

If you process more than $15,000 a month on a flat rate, this one change usually saves more than anything else on this list. It also makes your statement checkable, so you can confirm every month that you're billed what you agreed to.

2. Offer Dual Pricing

Dual pricing shows two prices before the customer pays: a card price and a lower cash or ACH price. Customers who pay by card, including debit, pay the card price, which covers your processing cost. Customers who pay cash or ACH pay less. It's legal in all 50 states when both prices are clearly posted. Puerto Rico is the exception.

Say you run $40,000 a month in card sales at a 2.9 percent effective rate. That's $1,160 a month in fees. With a card price that covers the cost, most of that $13,920 a year comes back to you. IntelliPay's Consumer Choice dual pricing program shows a "Total Price with Card" and a "Total Price with Cash/ACH" before the customer clicks Pay Now.

3. Move Large Payments to ACH

ACH has no card interchange, and the cost is usually a flat amount per payment no matter how big the invoice is. On a $2,000 invoice, a 2.9 percent card fee is $58. ACH typically costs a fraction of that. Businesses are already making the shift: Nacha reports 35.2 billion ACH payments in 2025, an average of 141 million a day. Here's how ACH payments work.

4. Send Line-Item Data on Business Cards

If you take corporate, purchasing, small business, or government cards, this changed in 2026. Visa retired Level 2 interchange for small business and commercial credit cards in April 2026. Only the fleet fuel program is left. The lower rate now requires Product 3 under Visa's Commercial Enhanced Data Program (CEDP), which means sending verified line-item invoice data.

The savings are smaller than they used to be. On a Tier 2 small business card, Product 3 Verified runs 2.55 percent plus $0.10, plus the 0.05 percent CEDP fee, compared with 2.70 percent plus $0.10 with no data. That's about 10 basis points, or roughly $150 a month on $100,000 in that card volume. We break down the numbers in Visa's January 24 small business card rate change. Ask whether your system sends complete, accurate data, because placeholder values won't qualify.

5. Keep Disputes Under Control

As of April 1, 2026, Visa's VAMP "excessive" threshold dropped to 1.5 percent for U.S. merchants, and merchants above it pay $8 per dispute on top of normal chargeback fees, according to the Merchant Risk Council. Use a clear billing descriptor, send reminders before recurring charges, and make cancellation easy. Our VAMP compliance guide covers the details.

6. Negotiate With Data

Processors negotiate. Most merchants just don't ask. Bring your monthly volume, average ticket, card mix, and effective rate. Ask for interchange-plus with a stated markup, and ask to drop fees that aren't doing anything for you. A competing quote or a free statement review gives you leverage. Request yours here.

Dual Pricing vs. Surcharging

People mix these up all the time, and the difference matters legally and at the register.
