Interchange Plus Pricing, Explained in Plain English

Most business owners never chose a pricing model for their card processing. It came with the account, and nobody explained it. That is fine until the monthly fees start to feel bigger than they should, and there is no easy way to tell why. This guide walks through interchange plus pricing in plain terms: what it is, how it compares with flat rate and tiered pricing, and how to tell whether it fits your business.

What interchange plus pricing means

Every card sale carries three kinds of cost. The name of this model simply describes how they are billed: the actual interchange cost, plus a separate markup you can see.

• Interchange goes to the bank that issued your customer's card. It is set by the card networks, not by your processor, and it changes with the type of card and how the sale was taken.
• Card brand fees go to Visa, Mastercard, Discover, and American Express. They are small, but they show up on every statement.
• The processor markup is what your provider charges for its service. It is usually a percentage, a small per-transaction fee, or both.

With interchange plus, the first two are passed through at cost and the markup sits on top as its own line. Nothing is blended together. You can see what the card networks charged and what your provider charged, side by side.

How it compares with flat rate and tiered pricing

There are three common ways a processor can bill you. None of them is wrong on its own. They just show you different amounts of what is going on underneath.

Flat rate

You pay one rate on every card, every time. It is the easiest model to budget around and the easiest statement to read. The tradeoff is that interchange still varies underneath. A basic debit card costs far less to accept than a premium rewards card, but a flat rate charges both the same. The difference becomes your provider's margin, and you cannot see it.

Tiered pricing

Your processor sorts each sale into buckets, usually called qualified, mid-qualified, and non-qualified, and charges a different rate for each. The catch is that the processor decides which sales land in which bucket. Two statements with the same card mix can look very different depending on those rules, and they are rarely written down for you.

Interchange plus

The real interchange cost of each sale passes through, and a fixed markup is added on top. When interchange is lower, you pay less. When it is higher, you can see exactly why. Your markup stays the same either way, so comparing one provider with another becomes a simple question: what are you adding on top?

Why the markup is the part that matters

Interchange is the same no matter who processes your cards. Nobody can negotiate it away. So when a provider says they can lower your costs, what they can really change is the markup, plus how your transactions are set up.

That setup piece is easy to overlook. Some sales qualify for lower interchange than others. A card tapped at the counter usually costs less than the same card typed in by hand. Business and purchasing cards can qualify for lower interchange when the right invoice data is sent with the sale. A good provider helps your transactions land in the best category they are eligible for, and interchange plus is the model that lets you actually see that happen.

What this looks like for a healthcare practice

Dental offices, medical practices, and specialty clinics tend to have larger tickets than a coffee shop and a wide mix of cards. Some patients pay at the front desk. Others pay later through a payment link or a card on file for a payment plan. Each of those can carry a different interchange cost.

On a flat rate, all of that disappears into one number. On interchange plus, you can see which kinds of payments cost more and decide whether anything about your checkout should change. For a practice collecting large balances every day, that visibility is often where the conversation about fees starts.

Is it always the cheapest option?

Not always, and it is worth being honest about that. A business with low volume and small, simple sales may be happier on a flat rate, where the statement is short and nothing moves month to month. Some businesses would rather pass the cost of credit cards to the customer, which is what dual pricing is built to do.

Interchange plus is one of the pricing models we offer. We do not pick one for you in advance. We run your real volume, average ticket, and card mix through each model and recommend whichever one costs you less.

Questions to ask about any pricing model

Whatever you are on today, these questions will tell you most of what you need to know.

• Does my statement show interchange, card brand fees, and your markup as separate lines?
• If I am on tiered pricing, what decides which bucket a sale lands in?
• Is my markup fixed, or can it change during the agreement?
• Are my sales set up to qualify for the lowest interchange they are eligible for?
• What monthly or annual charges sit on top of the per-sale costs?

Start with the statement you already have

You do not need to learn the whole card system to get a clear answer. Your most recent processing statement already holds it. If you want to read it yourself, our guide on how to read a merchant statement walks through each section. If you would rather hand it off, send it to us for a free fee audit. We will lay out what you pay today under your current model, show how the same volume would look under interchange plus pricing and our other models, and send you the side-by-side breakdown. You keep it either way.

We do not publish rates, because volume, ticket size, and card mix change the math too much for a number on a web page to be honest about your business. Most merchants see meaningful savings once their pricing is laid out clearly, though every statement is different.
