Your pay-later float survives - most fee-cutting advice would kill it.
Klarna, Afterpay and Affirm advance you the full amount on day one and carry the default risk themselves - the cheapest capital in your business, with no application. Presented right, they stop cannibalizing the buyers who’d happily have paid by card at a third of the cost, and show up exactly where they win a sale you’d otherwise lose. No platform builds this for you. It is your margin on the line, and it was never on their roadmap.
