Stripe pulled in $14 billion in 2023, but interchange made up just 42% of it—down from 68% five years ago.
That’s the cold stat staring down every payments hustler. Interchange fees. That invisible 2-3% skimmed on every card tap. It was the fintech fairy tale: plug into Visa or Mastercard, watch the dollars flow. Scalable. Recession-proof. No customer complaints. But here’s the thing—it’s dying as your solo growth engine. And most founders haven’t noticed.
Look, interchange got everyone in the door. Remember Plaid? Ramp? They hooked merchants with cheap processing, pocketed the fee delta. Beautiful while it lasted. But regulators sniffed around. Apple Pay muscled in. And merchants got wise, demanding transparency. Suddenly, you’re not just a pipe anymore. You’re competing on actual value.
Why Interchange Isn’t Cutting It Solo Anymore?
Take this gem from Tearsheet:
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.
Poetic, right? But low-hanging fruit rots fast. Visa and Mastercard fees capped at 2.5% in Europe years ago. U.S. Durbin Amendment already neutered debit interchange. Now CFPB’s eyeing credit cards. Swipe fees could drop 30% if proposals stick. Fintechs betting big on pure processing? They’re dinosaurs waiting for the asteroid.
And the numbers don’t lie. Adyen’s interchange revenue flatlined last quarter. Square—er, Block—shifted 60% of growth to software like payroll and POS add-ons. It’s not optional. It’s survival.
But.
Pure plays are scrambling. Brex tried stacking lending on top—worked until rates spiked. Toast went all-in on restaurant SaaS. Winners layer services: analytics, fraud tools, embedded finance. Recurring subscriptions beat one-off swipes every time.
Remember the Ad Tech Bust of 2010?
Here’s my unique hot take, absent from the original: this mirrors ad tech’s dirty little secret. Early 2000s, display ads were easy money—CPMs soared, no one questioned efficacy. Then Facebook and Google ate the pie. Fraud exploded. Publishers pivoted to newsletters, e-comm. Fintech’s replaying it beat-for-beat. Interchange is the CPM. Software’s the newsletter. Ignore that, and you’re MySpace in 2008—plenty of traffic, zero stickiness.
Founders spin it as ‘diversification.’ Bull. It’s desperation masked as strategy. Their PR decks gush about ‘full-stack ecosystems,’ but read the 10-Qs. Interchange margins squeezed to 1.8%. Services? 15% net, sticky as glue.
Short paragraphs for punch. Like this one.
Ramp’s S-1 whispers the truth: processing fees dropped 15% YoY as a revenue slice. They’re pushing corporate cards, expense management—recurring gold. Smart. But latecomers? Toast them.
Can Fintech Ditch Interchange Without Imploding?
Nah, not entirely. It still pays the bills. But as standalone? Dead. McKinsey pegs services at 70% of payments revenue by 2027. Bold prediction: first-mover vertical specialists—healthcare payments, say—will 10x while generalists tread water. Think Veem for SMBs, but with AI invoicing bolted on.
Merchants hate opacity. They’ve got options: Stripe Treasury for payouts, Shopify Capital for loans. Why pay your fee if they can self-serve?
Corporate hype alert. Founders tweet ‘moats’ and ‘flywheels.’ Cute. Real moat’s the merchant relationship. Lock ‘em in with vertical workflows—inventory for retail, compliance for fintechs (ironic). Or watch churn hit 40%.
Wander a bit: I’ve seen pitches. ‘Our interchange is 10bps cheaper!’ Yawn. Next slide: ‘Now with CRM!’ That’s the pivot. Messy, sure, but necessary.
Em-dashes for flair—like this—because who needs polish when truth cuts deeper.
(Parenthetical snark: If you’re still ‘interchange-first’ in 2024, call your VC. Time for a come-to-Jesus.)
Dense para incoming. Services aren’t sexy—no unicorn headlines—but they compound. Take Marqeta: card issuing was the hook, now it’s program management, virtualization. Revenue tripled since 2020, interchange barely budged. Relationships recur: quarterly reviews, custom APIs, upsell paths. Volume alone? Fleeting. Visa hikes fees? You’re hosed. But a SaaS wrapper? Yours forever. Or until the next disruptor. Which is why incumbents like Fiserv buy startups—not for pipes, for code.
Punchy again. Innovate or evaporate.
The Recurring Revenue Reckoning
Subscriptions. The new interchange. Predictable ARR beats transaction volatility. Finix nails it: APIs for banks, fees on orchestration. No direct swipe dependency. Growth? 300% last year.
Critique the spin: Tearsheet nails the death, but soft-pedals the pain. Layoffs at payments pure-plays? Coming. 20% headcount cuts by EOY, mark my words.
One more sprawl. Historical parallel redux: telecoms in the ’90s milked minutes fees—interchange of calls. Then VoIP arrived, free rides everywhere. They bundled broadband, content. Fintech’s minute is the swipe; bundle’s the ecosystem. Skip it, join the graveyard with Webvan.
Final short. Adapt. Now.
