If it works like here in Australia, the merchant pays a very high fee, but in return, there are no chargebacks and the BNPL financer pays straight away.
So in return for a high rate (merchant fee for AfterPay here in Australia is 4+%) the merchant gets guaranteed payment and no chargeback risk. The BNPL service makes money on the merchant fees and on the fact that this lending appeals to young people and those with low credit scores.
It's an extension of what used to be called "lay-by" here, but in that case, the merchant wouldn't release the item until it was paid in full.
