The question of how buy now, pay later (BNPL) point-of-sale credit can migrate to B2B channels is a relatively new twist on a very old concept — net payment terms for business-to-business (B2B) purchases. Perhaps debatably, B2B is the original BNPL use case. It’s still how most B2B purchases are made — net 30, 60, 90-day terms — so what does BNPL do to improve on this arrangement?
