Lending as BaaS Profit Engine
Banking-as-a-Service: The $1T Market to Build the Twilio of Embedded Finance
The real unlock in BaaS is that a company can turn financial features from a thin payments perk into a full margin engine. Card issuing mainly pays through interchange on each swipe, but lending adds interest income and balance sheet leverage. A platform that already sees deposits, payroll flows, invoices, or merchant sales can use that data to decide who gets credit, price risk, and earn more per customer than a card program alone.

Interchange is a small slice of each transaction. In the B2C example, the BaaS layer keeps about 0.12% and the fintech about 0.28%. Lending can be much larger because the provider earns ongoing interest, not just a one time payment fee when money moves.
-
The practical advantage is workflow data. A vertical software company that already handles dealer finance, sports fees, restaurant purchasing, or business spend can underwrite using real operating data that a bank often cannot see cleanly. That makes embedded credit more accurate and easier to distribute inside the product.
-
This is why BaaS broadens from fintechs into ordinary software and commerce platforms. Instead of launching a stand alone neobank, companies can add installments, cash advances, working capital, or payout linked accounts inside the product they already use, and monetize both the software workflow and the money flow.
Going forward, the strongest BaaS platforms will be the ones that help customers move from swipe based revenue to underwriting based revenue. As embedded finance spreads into vertical software and marketplaces, the winners will control the data loop, deposits, payments, and credit decisioning in one product, which makes lending the highest value layer on top of card issuing.
