THE CARD PENETRATION GAP
South Africa has roughly 80% bank account penetration but credit card penetration sits closer to 10%. Most consumers hold debit or prepaid cards that can't carry a revolving balance — meaning installment credit at checkout has no incumbent rail to compete with.
HOW BNPL ACTUALLY WORKS
The merchant gets paid in full immediately; the BNPL provider takes a 4–6% fee and assumes the credit risk on the consumer's installment plan. The provider's economics depend on cheap capital to fund receivables and on default rates staying under ~3%.
THE KLARNA PRECEDENT
Klarna pioneered the model in Sweden in 2005, expanded across Europe, then crashed valuation from $46bn to $6.7bn in 2022 when rates rose. *Cheap capital* is the entire substrate of the BNPL business — when funding costs spike, the unit economics invert overnight.
WHY EMBEDDED PAYMENTS WIN
Shopify and WooCommerce together power roughly 30% of global e-commerce stores. A payments provider that ships as a one-click plugin reaches thousands of merchants without any sales force — the platform is the distribution channel. This is why Stripe spent a decade building plugin-grade developer experience and why Stitch is racing to do the same in Africa.
THE REGULATORY GAP
South Africa's National Credit Act regulates lenders, but BNPL products structured as four-installment, zero-interest plans often fall outside its definition of credit. The UK began closing this loophole in 2024; South Africa has not. The grey zone is what makes the unit economics work.
THE FX EXPOSURE
Stitch's wholesale funding is mostly rand-denominated, but the merchants it serves increasingly sell to cross-border shoppers. Every move in ZAR/USD reprices both the cost of capital and the real value of receivables.
