best credit card processing for small businesses in 2026
Selecting a Pricing Model
One of the most straight forward ways to lower your credit card processing fees and optimize it for your business is simple by selecting the right pricing model for you. There is no single "correct" model; the right choice depends on your volume, the cards your customers use, how you that capture card data, and whether you want to absorb costs or pass them to your customers.
Below is a breakdown of the three most popular payment processing services to help you decide.
There are plenty of pricing models in the industry, but these are the main three used by businesses. Each has it’s pros and cons and is best suited for different businesses based on industry, size, and predictability. We’re going to look at:
and a Comparison of the three.
What is Interchange?
Interchange is part of the fees you pay when processing a credit card. They are like the toll fees for using the card networks. They are comprised of a percentage of the total sale plus a per transaction fee. Example: 1.4% + 10¢
Interchange Fees are non-negotiable fees set by the networks (Visa/Mastercard/etc.) but paid to the Issuing Bank. They vary mostly based on card type (example: a "Rewards" card costs you more than a "Debit" card). Here’s how the card types affect interchange.
Debit - Interchange on debit card is federally regulated by the Federal Reserve's Regulation II which limits interchange fees charged by large banks worth over $10 Billion (think Bank of America, Wells Fargo, etc). There are smaller banks that have exemptions (think Uwharrie Bank, local credit unions, etc.) but they still charge less than credit cards.
Regulation II "Covered" Debit Cards:
These are cards issued by large banks with over $10 billion in assets (e.g., Chase, Wells Fargo). Under the Durbin Amendment (Regulation II), these fees are strictly capped to ensure they are "reasonable and proportional" to the bank's actual costs.
They account for a small percentage of issuing banks, but over 61% of debit card transactions.
Exempt Debit Cards:
These are issued by smaller "community" banks and credit unions with under $10 billion in assets. Because they are exempt from federal caps, they can charge higher "market" rates to stay competitive with larger institutions.
Standard Credit Card:
These are basic consumer credit cards that do not offer high-tier rewards (often referred to as "Core" or "Traditional" cards).
Historically the interchange rate has been around 1.5%, however following a 2025/2026 anti-trust settlement, card networks are likely to have to cap interchange at 1.25% some time after the settlement terms are approved by the U.S. District Court for Eastern District of New York.
Rewards/Premium Credit Card:
These are "Super Premium" cards (e.g., Visa Signature Preferred, Mastercard World Elite) that offer extensive points, miles, or cash back. These were largely excluded from the 1.25% cap to allow banks to continue funding rewards programs.
NOTE: Interchange varies by more than just “card type”. Although that is the biggest factor, things like card network (Visa vs Amex), or issuing bank (Chase vs Wells Fargo) or account type (student checking vs business checking) and other such factors also can have minor influences on interchange rate.
Below is an assessment of different card types with examples of fairly typical interchange rates for various card types, along with the cost a merchant with a monthly volume of $10,000 and an average $50 transaction value might pay in interchange fee. The card mix is based on the percentage of total card transaction in the US according to the Federal Reserve. ¹ ² ³
Actual card mix will vary by customer demographic within a given timeframe.
| Card Type | Average Interchange | Card Mix | Per Transaction Fee | Number of Transactions | Total from $10,000 Volume |
|---|---|---|---|---|---|
| Covered Debit | 0.47% | 28.67% | $0.23 | 57 | $29.91 |
| Exempt Debit | 1.21% | 18.33% | $0.51 | 37 | $28.90 |
| Standard Credit | 1.5% | 13.25% | $0.10 | 27 | $23.39 |
| Rewards Credit | 2.5% | 39.75% | $0.10 | 80 | $130.98 |
| Total: 200 | Total: $213.18 |
Flat Rate Pricing: One Consistent Fee
1. Flat Rate Pricing: Simple and Predictable
Flat rate pricing is exactly what it sounds like: you pay one fixed percentage for every transaction, regardless of the card type used.
How it Works: The processor combines the wholesale rate (interchange) and their processor markup into a single fee. Common examples include Square or Swipe, often charging around 2.6% + 15¢ for in-person "card-present" transactions. Those are the transactions taken in the store.
Is Flat Rate’s Simplicity Right for your Business?
Pros:
It is highly predictable and makes merchant statement reconciliation simple.
You can also accept "elite" cards with high fees (like American Express) without paying extra because their average rate is already factored into the cost of every transaction.
Cons:
It can be less transparent and often more expensive long-term for especially for high-volume businesses.
You don't benefit from lower-cost cards, such as debit transactions.
If you take in too many high-cost cards, your rate and fees will be adjusted to compensate for processor losses.
Interchange Plus: Transparent & Fair
2. Interchange Plus Pricing:
Often called the most honest model, interchange plus pricing separates the non-negotiable interchange fee (set by Visa, Mastercard, etc.) from the processor's markup.
How it Works: You pay the interchange ("at-cost" price) from the card network plus a small, fixed markup fee to your processor. For simplicity, lets say your mark up was 1% with your business for in-person "card-present" transactions (the ones taken in the store). That’s the “Plus”.
Pros:
This offers the highest level of transparency. If card networks lower their fees, those savings are passed directly to you. It is frequently the cheapest credit card processing option for growing businesses with high transaction volumes.
Cons:
Your credit card processing statement will be much more complex. Because costs fluctuate based on the specific card used, monthly expenses are harder to predict.
Dual Pricing: No-Cost Processing
3. Dual Pricing (Cash Discounting): Protecting Your Margins
For many, the best credit card processor for small business is one that eliminates processing costs entirely. Dual pricing and cash discount programs have recently become the "big opportunity" for merchants to protect their bottom line.
How it Works: With Dual Pricing, you display two separate prices for every item (one for cash and one for card). Like a gas station, which displays both card and cash price.
Cash Discount: A subset of dual pricing, You list just one price: the "card price", and provide a discount if the customer pays with cash.
Pros: This model essentially results in zero fee credit card processing for the merchant, as the card-paying customer covers the cost of acceptance.
Cons: It requires clear, compliant signage and specific terminal setup to avoid issues with card brands like Visa. However this is what we can help you with so that you have a smooth transition.

Which Structure Is Right for You?
If you want a no-cost credit card processing solution to combat rising inflation, dual pricing is your strongest bet. However, if you prefer to absorb the fees as a standard operating expense and want the most data-driven breakdown, interchange plus pricing is the industry gold standard for transparency.
Regardless of the model you choose, remember that card-not-present (online or keyed-in) transactions will always carry higher rates due to increased fraud risks. Always compare providers based on your specific total processing volume to find the most cost-effective path.
