The Invoisure Field Notes
How to differentiate beyond interchange, build software revenue, and grow your portfolio. Written by Ryan Meo, founder of Invoisure.
Interchange is set by the card brands, not by you. So the strategic question for an ISO in 2026 is no longer how do I sell processing cheaper — it's how do I sell something the processor on the other end of the table can't take from me.
Across early-access conversations with ISOs adding software residual, five patterns keep showing up. Two of them are working consistently. Two are mistakes that recur enough to flag. One is a sleeper that nobody's optimizing for yet.
Most ISOs lose the software pitch in the first sentence. Not because the merchant doesn't want the software — they actually do — but because the pitch sounds like an upsell from a rep who's trying to hit a number.
If you searched 'white-label invoicing software' and landed on Akurateco, this is for you. Akurateco is a white-label payment gateway — the plumbing. Invoisure is white-label invoicing — the workflow software your merchant actually sees. These aren't alternatives; they're complementary layers.
The wholesale price is $25 a merchant. What ISOs charge on top of that ranges from $14 markup to $104 markup depending on segment, packaging, and confidence. Here's how the math works in the field.
Most ISOs searching for white-label invoicing find one of two things: white-label payment gateways (different problem) or agency invoicing tools (different ICP). The category that fits payment intermediaries is unoccupied. This is what it actually is.
