That’s not how BNPL works in its modern form with the third party companies. You pay late fees if you pay late. If you have a 3 month plan, they divide the payment into three equal installments and you pay it off.
The parent poster is confusing BNPL with cobranded cards like Room 2 Go credit cards that have special promotions with “0% for x months”. It’s a regular credit card where the minimum payment won’t guarantee that you pay the original amount off in “x” months, but you only have to pay 2% of the balance. These have always shown up on your credit report.
They are “deferred interest” plans where if you don’t pay the balance off in $x months it will charge you back interest.
