Start a Buy-Now-Pay-Later (BNPL) Provider

1. 1

   Internalize who actually pays you

   BNPL revenue comes overwhelmingly from merchants, not consumers: for a named operator like Klarna, 78.7 percent of commission revenue is from retailers and only about 15.7 percent from interest. Merchants pay 2 to 8 percent because BNPL lifts sales by roughly 20 percent, driven by buyers who would not otherwise convert. If you design the business around consumer interest, you have misread the model.

2. 2

   Understand the price-discrimination reality honestly

   NBER research documents that BNPL functions primarily as a merchant-subsidized tool to price-discriminate toward lower-creditworthiness customers, not a pure convenience. That is not a criticism; it is the economic engine, and understanding it tells you which merchants value BNPL most and how to price them. Be honest about this internally so your risk and pricing assumptions are grounded in what BNPL really does.

3. 3

   Raise lending capital and build funding

   You front the full purchase to the merchant and collect installments from the consumer, so you need lending capital and, at scale, a warehouse or forward-flow funding arrangement. This is a capital-markets business, not just software. Underestimating funding cost and default losses is how BNPL lenders bleed.

4. 4

   Build a real credit-decisioning model

   You approve or decline in milliseconds at checkout, and named operators reject roughly 13 percent of applicants for high default risk using bureau and alternative data. Your model is the difference between profitable conversion and a book of defaults. Invest in decisioning and monitoring from day one, and expect to buy scoring data from a bureau or alternative-data provider.

5. 5

   Get the licensing and CFPB-aware compliance right

   Installment lending triggers state lending licenses and increasingly explicit federal consumer-credit scrutiny; the CFPB has moved to treat BNPL more like credit cards in key respects. You need disclosures, dispute handling, and a compliance program built for a product regulators are actively watching. Treat this as a lending company that happens to sit at checkout.

6. 6

   Integrate at checkout and win merchants

   Your growth depends on being a one-tap option inside major carts and platforms, so merchant integration and platform partnerships are the go-to-market. Sell the roughly 20 percent sales lift and higher average order value, priced against your default risk for that merchant's customers. The merchant relationship, not consumer marketing, is where the volume comes from.

7. 7

   Manage default and reputational risk

   Late fees and interest are a minor revenue line, so your survival is about keeping default losses below your merchant-fee margin. Aggressive collections create regulatory and reputational blowback, so responsible lending is also risk management. The winners balance conversion, loss rates, and consumer trust deliberately.
