Fintech Architecture™: Buy Now Pay Later: How BNPL Business Models Actually Work (Fintech Architecture™ Series)

Description

The practitioner reference for anyone who needs to understand how BNPL business models actually work — not why they attracted so much capital, but why the unit economics that looked so compelling in 2020 and 2021 produced the valuation corrections and strategic pivots that followed. Fintech Architecture™: Buy Now Pay Later covers the five product variants from pay-in- four to super-app BNPL, the economics of merchant-subsidized versus consumer- funded models, and the specific analytical tools — installment-level delinquency tracking, multi-provider stacking exposure estimation, and the net contribution per transaction calculation — that distinguish prepared analysts from those who are still reading origination volumes when the business is already in crisis. The chapter on the CFPB's 2024 interpretive rule and its implications for the US BNPL market is the clearest available treatment of the regulatory reclassification that the category did not fully anticipate. The two case studies — Parc, a US BNPL provider navigating the transition from merchant-subsidized pay-in-four toward a diversified revenue model on fourteen months of remaining runway, and Parcelá, a Brazilian BNPL provider building a multi-product fintech on the foundation of the parcelamento culture — run every analytical concept through coherent, realistic narratives.
