Buy now, pay later and what it does to your books

Buy now, pay later has become a normal payment option on Malaysian stores. Atome, Shopee's SPayLater and similar providers appear at checkout beside cards and FPX, and conversion on higher-value baskets usually improves.

The accounting confusion is almost always the same mistake, and it is worth naming immediately.

You are not the lender

The customer takes a credit arrangement with the BNPL provider. The provider pays you — typically in full, typically promptly, less a fee that is higher than a card fee because the provider is carrying the credit risk.

The instalments are between the customer and the provider. They are not your receivable, they are not your revenue schedule, and they are not your credit exposure.

So on your books a BNPL sale is a completed sale, paid by a third party, with a larger processing fee. That is all.

Every complication people expect — instalment tracking, customer credit control, revenue spread over months — belongs to the provider, not to you. Getting this wrong in the other direction, by trying to mirror the instalment plan, creates work that has no accounting basis.

What is genuinely different

The fee is materially higher. Because the provider takes the default risk, the rate is typically well above card processing. That has real consequences: the same product sold via BNPL carries a thinner margin than one sold by FPX, and if BNPL is a meaningful share of volume, blending it into an average fee rate misstates margin on both sides of the mix.

Settlement timing follows the provider. Not your gateway. It may be a separate stream into your bank with its own report and cycle, even when the BNPL option appeared inside your normal checkout.

Refunds are three-cornered. You refund the provider, and the provider unwinds the customer's instalment plan. The mechanics and the timing are the provider's, and whether your original fee comes back is a question to ask specifically — often it does not. See what happens to the fee when you refund.

Chargeback exposure differs. The dispute route is generally the provider's process rather than a card network's, which changes both the timeline and who decides.

The margin question worth answering

BNPL raises average order value. That is why merchants enable it, and it is usually true.

It also costs more per transaction than any other method you accept.

Whether it pays is therefore an empirical question about your own data: does the uplift in basket size and conversion exceed the extra fee on the orders that used it? That is answerable, and almost nobody answers it, because it requires the fee to be recorded per method and per order rather than as a monthly lump.

The finding tends to be uneven. BNPL frequently pays handsomely on higher-value baskets and loses money on low-value ones, where a percentage fee on a small order is simply expensive. Knowing where the line sits lets you set a minimum basket for the option — a decision that requires the data first.

Recording it without inventing work

Record it as a completed sale. Revenue at gross, on the order date, with the provider's fee as a cost of sale. No instalment schedule anywhere in your ledger.

Track the fee separately from cards and FPX. It is the highest-cost method you accept and the one most likely to distort a blended average.

Reconcile the provider's settlement as its own stream. Its own report, its own cycle, matched to its own bank credits — see reconciling two gateways into one bank account.

Measure the uplift against the cost, by order value band, before deciding whether to keep it everywhere or restrict it.

The ShopeePay and SPayLater overlap

If you sell on Shopee as well as your own store, note that Shopee's own instalment option appears inside the marketplace settlement rather than as a gateway line. Same customer behaviour, entirely different money flow and reporting.

They should not be combined by brand or by concept in your reporting, because one is a deduction inside a marketplace payout and the other is a separate settlement into your bank. See how to read your Shopee settlement report.

Common questions

Is a buy now, pay later sale recorded as instalments?

No. The instalment arrangement is between the customer and the BNPL provider, which pays the merchant in full and carries the credit risk itself. On the merchant's books it is a completed sale on the order date at gross, with the provider's fee recorded as a cost of sale, and no instalment schedule appears in the ledger at all.

Why is the BNPL fee higher than a card fee?

Because the provider is taking on the customer's credit risk as well as processing the payment. That premium is real and material, so the same product sold through BNPL carries a thinner margin than one paid by card or FPX, and blending the rates into a single average misstates margin across the whole mix.

Does BNPL pay for itself?

It depends on order value and can only be answered from your own data. The uplift in basket size and conversion has to exceed the additional fee on the orders that used it, and the result is typically uneven — favourable on higher-value baskets and unfavourable on small ones, where a percentage fee is simply expensive relative to the sale.

How do BNPL refunds work for the merchant?

The merchant refunds the provider, and the provider unwinds the customer's instalment plan on its own timetable. Whether the original processing fee is returned varies by provider and is worth confirming specifically, since frequently it is not — leaving a cost attached to a sale that no longer exists.
