What is buy now pay later (BNPL)?

Buy now pay later, or BNPL, lets a customer take goods now and pay for them in instalments, often four payments over six weeks for small purchases. A third party provider pays the shop up front, usually minus a merchant fee, and collects the instalments from the customer, who typically pays no interest but may pay late or account fees.

For a shop, BNPL is a payment method that can lift conversion on larger baskets. For the customer it is credit, and since 2025 Australian law treats it that way.

How it works at checkout

The customer chooses the BNPL option, is checked by the provider, and agrees to a repayment schedule. The provider pays the shop the order value less its fee, so the shop carries no repayment risk once the sale clears. The customer then repays the provider, often the first instalment immediately and the rest every two weeks. Moneysmart notes that BNPL services usually charge fees rather than interest, including late fees, monthly account fees and payment processing fees.

The Australian licence rule

ASIC explains that the Treasury Laws Amendment (Responsible Buy Now Pay Later and Other Measures) Act 2024 extended the National Credit Code to buy now pay later contracts. From 10 June 2025, anyone engaging in credit activities involving these contracts must hold an Australian credit licence with the right authorisations and belong to the Australian Financial Complaints Authority. The obligation falls on the providers, not on the shops that offer them at checkout, but it means customers now get responsible lending checks and complaint rights.

When it helps a shop

BNPL tends to matter most where baskets are larger and the purchase is wanted now but budgeted over weeks: furniture, homewares, fashion, beauty and electronics. Providers pitch it to merchants as a way to complete more of those larger baskets. The trade off is the merchant fee, which is commonly higher than card processing, and the way returns work: refunds go back through the provider, who then adjusts the customer's remaining instalments.

Risks to be honest about

Moneysmart warns customers that BNPL makes overspending easier, that fees add up, that several services at once are hard to track, and that BNPL applications and missed payments can appear on credit reports and affect future loans. A shop that pushes BNPL hard, especially to younger customers, risks complaints and reputation. Present it as one option among others, show the full price, and never describe it as interest free without saying fees may apply.

Where it shows up in the product

OneCraft has no ready made store or checkout; the agent builds the shop from capability guides into the site's own database and sends the customer to Stripe Checkout to pay. Payments run through Stripe Checkout as a direct charge on the owner's connected Stripe account, with prices read from the site's database rather than the browser, on paid plans only; the platform fee is 2 percent on Starter, 1 percent on Pro and 0.5 percent on Pro+, with Stripe's own fees on top. Payments run through Stripe only, with no PayPal or cash on delivery flow, and refunds are made in the owner's Stripe dashboard. Stripe's own documentation lists the buy now pay later methods it supports and where.

Questions people ask

Does the shop get paid in full with buy now pay later?

The shop is usually paid the order value minus the provider's merchant fee, soon after the sale, regardless of whether the customer keeps up their instalments. The provider carries the repayment risk. Check the provider's settlement times and fee schedule, because both vary between providers and plans.

How do refunds work on a BNPL purchase?

The shop refunds through the provider rather than directly to the customer. The provider then reduces or cancels the customer's remaining instalments, or returns payments already made. Your normal refund obligations under consumer law still apply, and your returns policy should explain how instalment purchases are handled.

Is buy now pay later the same as lay-by?

No. With lay-by, the customer pays in instalments first and collects the goods after the final payment, and the shop holds the stock. With BNPL the customer gets the goods straight away and the provider pays the shop. Moneysmart points out that lay-by can be cheaper because it has no account keeping or late fees.

Can a small online shop offer BNPL?

Yes. Providers sign up merchants directly, and some payment platforms offer BNPL methods inside their hosted checkout, which avoids a separate integration. Before adding it, compare the merchant fee with your margin on typical orders, because a fee that is fine on a $300 dinner set can be painful on a $20 accessory.

Should a shop advertise buy now pay later as interest free?

Only carefully. BNPL providers often charge no interest but do charge late, account or processing fees, and calling the service free or interest free without mentioning fees risks misleading customers. Show the full price, link the provider's terms, and let the customer decide.
