The Battleground for Interchange Revenue

Portrait of Eshita Kohli Eshita Kohli Associate Content Strategist

The financial services landscape is currently defined by a battle for the primary financial relationship with SMBs. But while you are watching your deposit balances, there is a silent leak happening right in your P&L.

You are losing a piece of the approximately $50 billion per year in interchange revenue to agile, “card-first” fintechs like Ramp and Brex.

Here is exactly how they are taking it, and how you can take it back.

The “Silent Churn” of Spend Volume

When you lose an SMB’s spend volume to a fintech, it is often silent at first. The client doesn’t immediately close their account; instead, you just see a drop in their card spend volume.

They have moved their daily operational spend to a competitor’s card simply to get access to better expense management software. Your bank card is left sitting in the drawer for emergencies only.

The bank leadership realizes too late that they lost the high-margin interchange revenue because of software, not interest rates.

Why Your Card is Losing “Top of Wallet” Status

The reality is that legacy bank cards are “dull” (just payments), while fintech cards are “smart” (payments bundled with data and automation). Think about a construction foreman standing on a ladder. He physically cannot log into a clunky desktop portal to categorize a Home Depot expense or chase down a paper receipt.

If an employee knows that your bank card requires a manual login (high friction), but a competitor’s card triggers an instant text message to snap a photo of the receipt (zero friction), they will use the competitor’s card every time.

Every dollar spent on that “smart” card is a fee your bank just lost.

The Interchange Imperative: Software Drives Swipes

It is a simple math problem: ease of use equals revenue. When you add a real-time software layer to a standard card, the behavior of the cardholder changes overnight. In our analysis, enabling real-time notifications and instant receipt matching led to a 169% jump in spend volume on those cards within just six months. Feature-driven loyalty doesn’t just protect your current revenue—it creates a massive non-interest income stream by making your card the path of least resistance for every morning coffee and every ton of raw material.

Reclaim Your Revenue

You do not need a multi-year digital transformation project that touches your fragile core banking infrastructure to fight back. You just need a wrapper solution.

With Embedded Expense Management directly integrated into your existing programs, you can recapture that leaked revenue without needing to issue a new card.

  • Zero-to-live in months: Bypass the glacial roadmaps of legacy processors (like FIS or Fiserv) and launch a fintech-grade mobile experience in just 3 to 6 months.

  • Mobile-first / text-message capture: Meet non-desk workers where they are. If they can send a text message, they can submit an expense instantly.

  • A “one-stop shop” experience: Provide a fully white-labeled, unified experience where the client logs into your existing banking portal to access modern expense tools.

Stop the Bleeding and Arm Your Frontline

Don’t let your commercial cards become obsolete because of a software gap. For mid-sized and regional banks, adding embedded expense management isn’t just about launching a new feature; it is about survival, revenue protection, and arming your frontline staff.

Better than fintech cards, without changing your cards.
