The slow death of interchange as a standalone growth engine
- Interchange has long served as the go-to, dependable revenue source for payments-first fintechs.
- Today, interchange alone can’t drive sustainable economics; lasting profit comes from recurring relationships, services, and value-added tools.
Interchange gets your foot in the door, but software, services, and recurring relationships keep it open.
Interchange – the small fee collected on every card transaction – has been payments-first fintech’s easiest and most dependable source of revenue. Invisible to users, scalable at high volume, and seemingly recession‑resistant, it was the low‑hanging fruit of payments economics. It gave even a brand-new card startup a revenue stream from day one.
But the narrative has evolved today. Interchange still matters, but less as a growth driver. It’s becoming infrastructure: a cost of entry that enables transaction flow, but not the sole source of meaningful value creation. This transition is most evident in the financial filings, quarterly segment reporting, and investor focus of leading payments players such as Block, PayPal, and Shopify.
These firms generate significant revenue from payments, but are increasingly emphasizing monetization beyond interchange. The message to the market is clear: Interchange gets your foot in the door, but what you do with the customer afterward matters more to the business.
