Buy now, pay later: what the checkout button does not say

Splitting a purchase into instalments is a loan with a very short term. The interest-free framing is accurate and incomplete: the consumer protections attached depend on the legal form of the agreement, not on whether interest is charged.

Three things to establish before using it

1. Whether the provider reports the account to credit bureaux, and when.
2. What happens on a missed instalment — fee, interest, or referral to collections.
3. How a refund is processed if the merchant cancels the order mid-plan.

Refunds are the friction point

With a returned item, the merchant refunds the provider and the provider unwinds the plan. Until that settles, instalments can continue to be collected. Disputes therefore run through the provider's process rather than a card scheme's chargeback rules, which are more established.

The stacking problem

Individual plans are small; several running concurrently are not, and they are easy to lose track of because they do not appear on a single statement. Regulators in several markets have moved BNPL toward mainstream credit rules for precisely this reason.
