Short answer: Flat-rate pricing charges one blended rate on every card, simple to read but often more expensive for businesses with many debit or basic-card sales. Interchange-plus passes through the card networks' interchange cost and adds a disclosed markup, so the statement is longer but you can see what the processor actually earns.

Two ways of charging for card processing. One is simple to read; the other shows you the real cost of each card. Which is cheaper depends on your sales.
With flat-rate pricing, every card sale costs the same percentage, sometimes plus a small fixed amount, regardless of the card type. It is easy to understand and easy to forecast.
With interchange-plus pricing, you pay the actual network cost of each card, which changes with the card type and how it was accepted, plus a fixed markup from the processor. It is more detailed to read but shows exactly what each part costs. For many established businesses with steady volume it can work out lower, while for very small or irregular sellers flat-rate is often simpler.
New businesses, low volume and owners who want one predictable number.
Businesses with steady volume who want to see each cost and negotiate the markup.
Lots of debit and card-present sales tend to favor interchange-plus; many keyed or premium rewards cards change the math.
Divide total fees by total sales for each option to compare like with like.
| Flat-rate | Interchange-plus | |
|---|---|---|
| How the cost is set | One rate for most cards | Network cost plus a fixed markup |
| Easy to read? | Yes | Takes a little practice |
| Shows the true network cost? | No | Yes |
| Typical fit | Small or irregular volume | Steady, growing volume |
A coffee shop with mostly small tap transactions compares three months of statements under both models. It calculates an effective rate for each by dividing total fees by total card sales, then compares those effective rates rather than the advertised headline numbers, and asks about the markup and monthly fees before deciding.
A device or pricing decision looks bigger on paper than it is in practice. Most owners are well served by choosing for their busiest ten minutes, keeping the first setup simple and adding pieces as volume proves the need.
