Key Takeaways

• Interchange Plus pricing passes the actual card network cost directly to the merchant, then adds a fixed markup on top
• Unlike flat-rate pricing, Interchange Plus gives you full visibility into what you are actually paying and why
• Small businesses processing more than $10,000 per month in card transactions often see lower overall costs with Interchange Plus
• PaymentCollect offers both flat-rate and Interchange Plus pricing so you can choose based on your card mix and volume

If you have ever looked at a processing statement and had no idea what you were paying or why, you are not alone. According to the Federal Reserve Payments Study, card payments now account for more than 50% of all non-cash payments in the United States, and most small business owners are paying for that volume without fully understanding what drives their costs. Interchange Plus pricing is one of the clearest ways to fix that.

What Does Interchange Plus Pricing Actually Mean?

Interchange Plus is a pricing model where your payment processor charges you two separate, visible line items: the wholesale interchange rate set by Visa, Mastercard, or Discover, plus a fixed markup the processor adds on top.

The interchange rate is not set by your processor. It is determined by the card networks based on factors like card type (debit vs. rewards credit), how the card is presented (chip, swipe, or keyed), and your business category. According to the Nilson Report, interchange rates across all card types in the U.S. range from roughly 0.05% for regulated debit cards to over 2.5% for premium rewards cards.

The processor markup is where Interchange Plus gets its name. If your processor charges “interchange + 0.25% + $0.10,” that 0.25% and $0.10 is their fee on every transaction. Everything else goes to the card network and the issuing bank, and you can see both numbers clearly on your statement.

How Is This Different From Flat-Rate Pricing?

Flat-rate pricing bundles every cost into one visible percentage. You pay the same rate whether a customer taps a basic debit card or hands you a premium airline rewards card. That simplicity has a cost: your processor pockets the difference between what they actually pay the card network and what they charge you.

For businesses with a high volume of debit card transactions or basic credit cards, that spread can be significant. A flat rate of 2.6% on a transaction that carries a 0.9% interchange rate means your processor keeps a 1.7% margin on that sale.

“Flat-rate pricing is predictable, but predictable is not the same as inexpensive,” says Ben Dwyer, founder of CardFellow, a payment processing comparison platform. “For merchants with consistent volume and a favorable card mix, Interchange Plus almost always wins on total cost.”

For businesses where customers frequently pay with basic debit cards, corporate accounts, or standard Visa/Mastercard consumer cards, Interchange Plus can produce meaningfully lower effective rates. The PaymentCollect point of sale system supports both pricing models, so you are not locked into one structure.

Which Type of Business Benefits Most From Interchange Plus?

Not every merchant is a good fit for Interchange Plus. The model rewards businesses that process higher volumes and have predictable card mixes.

You are likely to benefit from Interchange Plus pricing if:

1. You process more than $10,000 per month in card transactions
2. Your customers frequently pay with debit cards or standard consumer credit cards (rather than premium rewards cards)
3. You want full visibility into your processing costs rather than a simplified single rate
4. You are running a retail or service business where volume trends are consistent month to month
5. You have the time or a bookkeeper who can read a more detailed monthly statement

You might prefer flat-rate pricing if your volume is lower, if you want maximum simplicity, or if your customer base skews toward premium business and travel rewards cards where the interchange rates are already high.

The QuickBooks Online plugin from PaymentCollect posts transactions automatically, which means your accountant or bookkeeper gets the data they need regardless of which pricing model you choose. That eliminates one of the traditional arguments against Interchange Plus: the more complex statement.

What Drives Interchange Rates Up or Down?

Understanding what affects interchange can help you make smarter decisions at the point of sale.

According to Visa’s published interchange rate schedule, the following factors affect the rate applied to any given transaction:

• Card type: Rewards cards, business cards, and corporate cards carry higher interchange than standard consumer cards or regulated debit cards
• Card entry method: Chip (EMV) transactions generally qualify for lower rates than manually keyed transactions
• Business category: Certain MCC (Merchant Category Codes) receive preferred interchange rates, particularly grocery, utilities, and government payments
• Transaction size: Some rate categories include a per-transaction cap that benefits merchants with large average ticket sizes

This is why accepting chip cards and tap payments (Apple Pay, Google Pay) through a certified payment terminal matters beyond just security. It also affects which interchange tier your transactions qualify for, which directly affects your cost on an Interchange Plus plan.

PaymentCollect’s PAX terminals support EMV chip, NFC tap payments, and PIN debit, giving your transactions the best possible chance of qualifying at the lowest applicable interchange tier.

How to Read an Interchange Plus Statement

One common objection to Interchange Plus is that the statement looks more complicated. That is true, but it tells you exactly where every dollar went.

A typical Interchange Plus statement will show:

1. Total volume processed
2. Interchange fees paid to card networks (broken down by card type)
3. Assessment fees from Visa/Mastercard
4. Processor markup (your negotiated rate)
5. Total effective rate (a useful benchmark for comparing months)

Your effective rate is your total processing cost divided by your total volume. Tracking this number month over month is far more useful than staring at a flat-rate percentage, because it reveals how your card mix shifts over time. If you notice your effective rate creeping up, it usually means more customers are paying with premium rewards cards, and that is actionable information.

For businesses that use the PaymentCollect all-in-one payment solution, QuickBooks Online captures the transaction data automatically, which makes it easier for your accountant to reconcile the statement without a separate manual process.

What PaymentCollect Charges: Transparent by Design

PaymentCollect publishes its processing fees directly on the point of sale product page, which is unusual in an industry where rate opacity is the norm. You can choose between plans where processing fees are paid by the merchant or plans where a surcharge is passed to the customer.

For businesses that want custom pricing using Interchange Plus, PaymentCollect offers that through direct conversation with their sales team. There are no middlemen determining your rate at a corporate level; the discussion happens with the same U.S.-based team that handles your support calls.

That is a structural difference from national processors. When you call PaymentCollect with a question about your statement, you reach the same team that set up your account and understands your business. According to a BrightLocal survey, 59% of consumers prefer businesses that offer personalized service, and the same logic applies when business owners are choosing who to trust with their payment infrastructure.

Summary

Interchange Plus pricing gives small business owners full visibility into what drives their processing costs. It passes the actual card network wholesale rate directly to you and layers a clear, fixed processor markup on top. For businesses processing meaningful monthly volume, particularly those with customers who frequently use debit cards or standard consumer credit, the total cost is often lower than flat-rate alternatives. PaymentCollect offers both pricing structures and publishes its fees openly, so you can make an informed decision rather than a guess.

Frequently Asked Questions

What is the difference between Interchange Plus and flat-rate pricing?

Flat-rate pricing charges one bundled percentage on every transaction regardless of card type. Interchange Plus separates the wholesale card network cost from the processor’s fixed markup, giving you visibility into both. Businesses with higher volume and a favorable card mix often pay less overall with Interchange Plus.

Can small businesses qualify for Interchange Plus pricing?

Yes. Interchange Plus is not exclusive to large merchants. PaymentCollect offers Interchange Plus options for businesses of various sizes. The model tends to provide the most benefit at volumes above $10,000 per month, but it is worth discussing with the sales team based on your specific card mix.

Does using a chip card terminal lower my interchange rate?

In many cases, yes. EMV chip and NFC tap transactions often qualify for lower interchange tiers than manually keyed or swiped transactions. Using a certified terminal like the PAX A80 or PAX A920Pro ensures your transactions meet the card network requirements for preferred interchange qualification.

How do I know which pricing model is right for my business?

The answer depends on your monthly volume, card mix, and how much time you want to spend reviewing statements. PaymentCollect’s sales team can review your current processing history and help you compare what each model would have cost over the past several months. Contact the sales team to start that conversation.

Is Interchange Plus harder to reconcile in QuickBooks?

Not with PaymentCollect. The QuickBooks Online integration posts transactions automatically, so your bookkeeper works from clean data regardless of how your pricing is structured. The statement is more detailed, but the bookkeeping side is handled for you.

What are assessment fees and are they included in Interchange Plus?

Assessment fees are separate from interchange and are charged by Visa, Mastercard, and Discover directly for the use of their networks. On an Interchange Plus statement, these appear as a line item between the interchange and the processor markup. A transparent processor shows all three components clearly.

Can I switch from flat-rate to Interchange Plus later?

Yes. Pricing structures can be adjusted based on your evolving business needs. If your volume grows or your card mix changes, it is worth revisiting which model produces a lower effective rate. PaymentCollect’s U.S.-based support team can help you evaluate that at any point.

Conclusion

Interchange Plus is not the right fit for every business, but it is the right conversation for any business owner who wants to understand what they are actually paying for. Transparency in pricing is one of PaymentCollect’s core commitments, and that extends to helping you choose the structure that makes the most sense for your operation, not the one that benefits the processor most.
