Buy now, pay later (BNPL) is short-term credit offered at checkout: the customer takes the purchase today and pays for it in a few fixed instalments, usually interest-free if every payment is on time. The BNPL provider pays the merchant upfront and earns mainly from a merchant fee rather than from interest. It has spread so quickly because it takes seconds at checkout, costs the customer nothing when used as intended, and helps merchants close sales that a full upfront price would lose.
This guide is written for the banks, finance companies and fintechs that offer BNPL or plan to. It covers how BNPL works, why customers and merchants use it, how it is regulated in the UAE, Saudi Arabia, Egypt and the UK, and what the platform behind it has to do.
How BNPL works
- Checkout. The customer picks BNPL as the payment method online, in an app or at a till.
- Decision. The provider checks identity, the customer’s limit and, where the rules require it, affordability. The answer comes back in seconds.
- Merchant settlement. The provider pays the merchant the purchase price, less its fee.
- Repayment. The customer pays the provider in fixed instalments, often four payments over six weeks or monthly payments over up to a year, usually collected automatically from a card or account.
- Collections. If a payment is missed, the provider sends reminders, may pause the customer’s limit and, where the rules allow, charges a late fee.
Why BNPL is so popular
For customers
BNPL spreads the cost of a larger purchase without a credit card or a loan application, and it costs nothing extra when paid on time. Sign-up and approval happen inside the checkout, which suits younger, mobile-first shoppers and people with a thin credit history.
For merchants
Offering instalments at checkout removes the upfront price as a reason to abandon the basket, so merchants use BNPL to lift conversion and order values and to reach customers who would not use a card. The provider carries the credit risk and pays the merchant upfront, so the merchant’s cash flow is unaffected.
For lenders
For a bank or finance company, BNPL is a way to win customers at the moment they buy, with a product that is small, short and repeatable. Merchant fees give a revenue stream that does not depend on charging the customer interest, and every transaction adds repayment data that improves the next credit decision.
BNPL compared with credit cards and personal loans
| BNPL | Credit card | Personal loan | |
|---|---|---|---|
| When approved | At checkout, for one purchase | In advance, as a revolving limit | In advance, for a fixed amount |
| Cost to the customer | Usually none if paid on time | Interest on any balance carried over | Interest from the start |
| Main revenue for the lender | Merchant fee | Interest and interchange | Interest |
| Term | Weeks to about 12 months | Revolving | Months to years |
| Credit assessment | Quick check at checkout; affordability checks where required | Full check at application | Full check at application |
BNPL regulation in the UAE, Saudi Arabia, Egypt and the UK
Regulators in Fimple’s markets have moved BNPL from a grey area into licensed lending. The details differ, but the direction is the same: licensing, affordability limits, clear disclosure and reporting.
- Saudi Arabia. The Saudi Central Bank (SAMA) issued its rules for BNPL companies on 17 December 2023. They cover licensing, minimum standards for offering BNPL, consumer protection, information security and financial crime, and they define BNPL as financing to buy goods or services with no term cost payable by the consumer.
- United Arab Emirates. Under the Central Bank of the UAE’s framework for short-term credit, BNPL can only be offered by licensed banks and finance companies, or by approved agents and restricted licence finance companies. The credit runs for up to 12 months without interest, and a restricted licence finance company or agent may lend no more than AED 20,000 or three months of verified net income, whichever is lower.
- Egypt. BNPL falls under the Financial Regulatory Authority and Consumer Finance Law No. 18 of 2020; FRA decrees set model contracts and affordability and instalment-to-income limits. In February 2026 the FRA suspended new consumer finance licence applications for a year.
- United Kingdom. The Financial Conduct Authority has regulated BNPL as deferred payment credit since 15 July 2026. Providers must be authorised or hold a temporary permission, lend responsibly and affordably, give customers clear information before and during the agreement, and support customers in financial difficulty.
For a provider, these rules land in the platform: limits, affordability checks, disclosures and regulatory reports have to be part of the lending workflow and the ledger, not managed on the side.
What a BNPL platform has to do
Decide in seconds
The decision happens inside the checkout, so identity checks, credit limits and affordability rules have to run in real time. A slow or failed decision is a lost sale for the merchant.
Integrate with merchants
Merchants connect through checkout plugins, point-of-sale integrations and APIs. The platform has to onboard merchants, apply each one’s fee terms, handle refunds and returns, and settle with them on schedule.
Run the ledger behind every instalment
Each purchase becomes a small loan with its own schedule. The loan management layer has to track instalments, merchant settlement, fees, missed payments, arrears and provisioning across very high volumes of very small loans. Our BNPL platform guide covers the build decisions in more detail.
Support Sharia-compliant BNPL
In Saudi Arabia and much of the GCC, BNPL has to work for Islamic finance. That usually means a Murabaha structure in which the lender buys the goods and sells them on at a disclosed price, with the contract recorded in the ledger itself. See Sharia-compliant BNPL in Saudi Arabia, which also covers the Murabaha and Ijara structures.
Report to the regulator
Licensing comes with reporting. The platform has to produce the lending, affordability and complaints data each regulator asks for, from the same records that run the product.
Risks and criticisms
BNPL’s simplicity is also its main risk. Customers can stack plans across several providers, lose track of due dates and run up late fees, and light-touch checks can let people borrow more than they can repay. That is why regulators have moved to affordability limits and clearer disclosure. Responsible providers add payment reminders, spending limits and affordability checks of their own.
The future of BNPL
BNPL is now a mainstream payment method. In August 2021 Square, now Block, agreed to buy Afterpay in an all-stock deal valued at about $29 billion, a signal of how large the market had become. Three shifts are under way: BNPL is moving from online checkouts into stores, travel and healthcare; banks are building it into their own apps as an alternative to cards; and the model is extending to businesses buying from suppliers. The next step, XNPL, applies the same instalment logic beyond retail purchases.
How Fimple supports BNPL
Fimple’s BNPL infrastructure is delivered as a service for banks and non-banks on its cloud-native core banking platform. It brings credit limits, loan origination, repayment scheduling and merchant settlement together with an API and low-code tools for connecting merchants’ point-of-sale systems. Because Fimple runs Islamic and conventional products on one platform, an institution can offer conventional and Islamic BNPL products on the same system. For lenders in Egypt, see BNPL in Egypt.
In November 2025 Fimple announced a partnership with OneFor, a Germany-based digital financial platform, to power its fully automated BNPL services in Southeastern Europe, with instant approvals, automated repayment plans and repayment collection.

Frequently asked questions
What does BNPL mean?
BNPL stands for buy now, pay later: short-term credit at the point of sale that lets a customer take a purchase now and pay for it in a few fixed instalments, usually without interest if every payment is made on time.
How do BNPL providers make money?
Mainly from merchants. The provider pays the merchant upfront, minus a fee, and collects the instalments from the customer. Late fees, where the rules allow them, and longer interest-bearing plans in some markets add to that.
Is BNPL regulated?
Increasingly, yes. Saudi Arabia’s central bank issued rules for BNPL companies in December 2023, the UAE central bank regulates it under its framework for short-term credit, Egypt regulates it as consumer finance, and the UK brought it under FCA regulation on 15 July 2026.
Is BNPL Sharia compliant?
It can be. Islamic BNPL is usually structured as a Murabaha sale or as an interest-free deferred payment with no profit from late payment; in Islamic finance practice late payment charges go to charity rather than to the lender’s income. Each provider’s Sharia board decides whether a specific product complies.
What is the difference between BNPL and a credit card?
A credit card is a revolving limit approved in advance that charges interest on any balance carried over. BNPL is approved at checkout for one purchase, splits it into a fixed number of instalments and is usually interest-free, with the merchant paying the main fee.
