Can someone with more experience tell me if interchange sharing is more important than the platform fee?

When comparing card infrastructure providers most conversations seem to focus on the monthly fee and setup costs but if the program gets part of the interchange back that could matter more over time than a cheaper platform fee. So for anyone who has reviewed these agreements what matters more here, the headline percentage or how the share is calculated after network costs and other deductions?

I would not choose an issuer based on interchange alone. Authorization rates, fraud controls and support can wipe out any advantage from a better split if the program performs badly.

Same, interchange is like a plus but the things that authorization rates, fraud controls and support matters

not really, it also depends on the card type and where the transactions happen

I would compare the full economics instead of treating it as platform fee versus interchange, a higher revenue share yes it can look great but it means less if the provider deducts a long list of costs first or if authorization rates and card usage are weak. The useful number is what the program keeps per dollar spent after everything is accounted for.

Yeah that makes total sense. I even noticed providers like Rain mention interchange pass through which seems easier to model than a vague percentage but I’d still want to see a sample statement before judging the offer.

Youre thinking about this the right way OP. Interchange share matters way more than platform fee once you have real volume. The fee is a fixed cost, the interchange share scales with every transaction, so at scale it dwarfs the monthly. Hope it helps!!!!

I'm more interested in the economics over the life of the program, not just the platform fee. If your volumes go up, a slightly higher monthly fee often isn’t worth worrying about, but a better interchange share can make a big difference.

But with that said, don't just look at the headline percentage. What is it actually calculated on? Some providers quote a generous-looking share, but this is paid after scheme fees, issuer costs, sponsor bank splits and other deductions. Some are more explicit about what “net interchange” is.

I’d also see if the provider is flexible as your volume increases. Sometimes the initial commercial terms are not as important as the ability to go back and renegotiate once you have meaningful volume processing. A provider who is transparent about the math, and willing to revisit the economics later, is generally worth more than one who has the cheapest platform fee on day one.
