Buy now, pay later (BNPL) allows customers to purchase products immediately and spread their payments over several installments. For online retailers, it can make expensive products more accessible, reduce checkout friction, and potentially increase average order value.
However, BNPL is not free for merchants. Providers typically charge transaction fees that may be higher than standard card processing, and the additional sales do not always translate into additional profit. Understanding the costs, risks, and customer behavior is essential before adding installment payments to your store.
What Is Buy Now, Pay Later for Merchants?
Buy now, pay later is a payment method that lets shoppers split the cost of an eligible purchase into installments or postpone payment until a later date. Depending on the provider and product, customers may pay in four installments, pay after a short period, or choose a longer financing plan.
From a merchant’s perspective, BNPL is a checkout financing option rather than simply another card payment method. In many standard arrangements, the provider pays the merchant the purchase amount minus applicable fees, then collects installments from the customer.
The provider generally manages customer repayment and assumes agreed credit risk, but this does not automatically eliminate the merchant’s exposure to refunds, fraud, fulfillment disputes, or contractual exceptions. The agreement determines who is responsible for each situation.
For customers
Pay over time instead of paying the full purchase price at checkout, subject to approval and the plan’s terms.
For merchants
Offer another payment option while typically receiving settlement from the provider, less agreed fees.
For providers
Assess eligibility, administer payment plans, collect installments and earn revenue under their business model.
How Does BNPL Work for Online Businesses?
The exact process varies by provider, but a typical BNPL transaction follows these steps:
- The customer selects BNPL. It appears alongside cards, digital wallets and other checkout methods.
- The provider assesses the purchase. The customer may need to provide information or pass an eligibility check.
- The transaction is approved or declined. Approval depends on the provider’s criteria, the customer and the purchase.
- The merchant fulfills the order. The store follows its normal order-processing and delivery procedures.
- The provider settles the merchant’s funds. Payment timing and deductions depend on the agreement.
- The customer repays the provider. The provider manages the agreed installment schedule and collection process.
Common BNPL payment models
- Pay in installments: The customer divides the purchase into a set number of payments.
- Pay later: The customer pays the full amount after a defined period, subject to the service’s terms.
- Longer-term financing: Eligible purchases may be paid over several months, potentially with interest.
These models should not be treated as interchangeable. A short interest-free installment plan can have different fees, customer eligibility requirements, disclosures and refund rules from longer-term financing.
Pros of BNPL for Merchants
1. Potentially higher conversion rates
Some customers abandon checkout because they cannot or do not want to pay the entire price immediately. Offering installments can reduce this barrier, particularly for considered purchases or higher-value products.
The actual improvement depends on your audience, product category, prices and existing payment options. If most customers already prefer cards and convert successfully, BNPL may have a smaller incremental effect.
2. A higher average order value
Installments may make a more expensive item, product bundle or upgrade feel more manageable. This can encourage customers to choose a higher-priced product or add complementary items to their basket.
However, a larger average order value is not automatically better. Measure contribution margin after the BNPL fee, discounts, shipping, returns and other variable costs.
3. Access to new customer segments
Some shoppers actively look for installment options or prefer not to use a traditional credit card. Providing an eligible BNPL method may make your store more attractive to those customers.
Availability differs by country and provider, and not every shopper will qualify. BNPL should complement an accessible set of payment methods rather than become the only way to complete a purchase.
4. Less direct repayment administration
In many provider-led arrangements, the BNPL company handles the customer’s installment schedule, payment reminders and collection process. The merchant does not need to build its own consumer credit operation.
The merchant still needs processes for order issues, returns, customer questions, reconciliation and disputes. Make sure your support team knows how to route financing questions to the provider.
5. Potential differentiation from competitors
A clear installment option can distinguish your checkout from competing stores that only accept immediate payment. This may be useful in product categories where customers compare prices carefully or need time to budget for a purchase.
Cons of BNPL for Merchants
1. Higher transaction fees
BNPL providers often charge merchants more than standard card processors. The fee may include a percentage of the sale and, in some arrangements, a fixed transaction component. Pricing varies by provider, country, payment plan, business risk and negotiated volume.
A fee that looks small in percentage terms can materially reduce profit when your products have narrow margins. Calculate the impact before enabling BNPL across your entire catalogue.
2. Higher sales do not guarantee higher profits
BNPL can increase gross revenue while reducing the contribution margin on each transaction. If most customers who select BNPL would have bought anyway using a lower-cost payment method, the provider fee may simply add expense to existing sales.
The key question is not how many shoppers select BNPL. It is how much additional profitable business it generates after all incremental costs.
3. More complicated refunds and reconciliation
A return may require the merchant to issue a refund through its normal system while the provider adjusts the customer’s remaining balance. Depending on the agreement, some original processing fees may not be returned.
Finance teams should understand settlement reports, partial refunds, cancellations, failed orders and the timing of provider adjustments. Poor reconciliation can create accounting errors and unnecessary support requests.
4. Customer service can become more complex
Customers may contact the store about installment schedules, payment failures, late fees or financing decisions, even when the provider controls those processes. Your team needs clear guidance on which issues it can resolve and which must be referred to the financing company.
5. Eligibility and spending limits
Not every shopper or order will qualify. Providers can apply transaction limits, merchant eligibility rules, fraud checks and approval criteria. A customer may see BNPL advertised but receive a decline at checkout.
Avoid making the entire checkout journey dependent on financing approval. Keep alternative payment methods available where possible.
6. Regulatory and reputational considerations
BNPL involves consumer credit or deferred-payment arrangements, and applicable requirements differ across jurisdictions and product structures. Rules may cover advertising, disclosures, affordability checks, complaints, privacy and customer eligibility.
Merchants should review the provider’s approved marketing language and avoid implying that financing is guaranteed or universally interest-free. Confirm the rules that apply in every market you serve.
How Much Does BNPL Cost Merchants?
There is no universal BNPL merchant fee. Providers set different commercial terms, and the price offered to one retailer may differ from the price offered to another.
Common cost components include:
- Percentage transaction fee: A percentage of the purchase price.
- Fixed transaction fee: A set amount charged per transaction, where applicable.
- Integration or service fees: Potential setup, platform or other service costs.
- Refund-related costs: Some processing fees may not be returned after a refund.
- Promotional financing: A merchant may subsidize an offer advertised as interest-free or otherwise discounted.
- Operational costs: Staff time, reporting, customer support and reconciliation.
Example: BNPL fee versus card processing
Consider a hypothetical €100 order. If the BNPL fee were 5.5% plus €0.30, the fee would be €5.80. If the alternative card fee were 2.0% plus €0.25, the card fee would be €2.25. The incremental payment cost would be €3.55.
These are illustrative numbers, not advertised rates from a specific provider. The difference means the BNPL order must generate enough incremental contribution to justify the additional cost.
| Cost factor | What merchants should check |
|---|---|
| Merchant transaction fee | Percentage, fixed fee, pricing tiers and minimum charges. |
| Settlement | When funds arrive and whether fees are deducted before payout. |
| Refunds | Whether fees are refunded and how partial returns are handled. |
| International orders | Country availability, currency conversion and cross-border charges. |
| Promotions | Who funds interest-free offers and any associated promotional fees. |
| Operational overhead | Integration, customer service, reporting and accounting effort. |

Best BNPL Providers for Merchants
The right provider depends on your target countries, ecommerce platform, product category, average order value and the financing terms you want to offer. The providers below are a starting shortlist, not a universal ranking.
| Provider | Potential fit | What to investigate |
|---|---|---|
| Klarna | Retailers serving supported markets, including European customers. | Available payment plans, country coverage, merchant pricing and refund terms. |
| Afterpay / Clearpay | Eligible retailers offering installment payments in supported markets. | Merchant eligibility, order limits, local product availability and fees. |
| Affirm | Eligible merchants offering short-term or longer-term financing, particularly in North America. | Supported countries, financing programs, approval rules and contract-specific costs. |
| PayPal Pay Later | Merchants who already use PayPal and want to evaluate its eligible deferred-payment options. | Local availability, qualifying transactions, fees and integration requirements. |
| Stripe-supported BNPL methods | Businesses using Stripe that want to explore supported BNPL methods through an existing integration. | Dashboard eligibility, available providers, method-specific pricing and customer markets. |
| Adyen-supported BNPL methods | Merchants evaluating a broader payment setup across multiple markets. | Supported local methods, contract terms, integration requirements and total cost. |
Klarna
Klarna offers payment options in a range of supported markets. It may be worth evaluating if you sell to consumers who are familiar with its brand or if you want to provide several ways to pay over time. Confirm the products and terms available to your specific business and customers.
Afterpay and Clearpay
Afterpay, known as Clearpay in the UK, is associated with installment-based shopping. Its relevance depends on the countries it serves, the merchant’s eligibility and the purchase types it supports. Check merchant pricing and refund procedures before adding it to checkout.
Affirm
Affirm provides financing options for eligible customers and merchants, including some longer-term plans. It is particularly worth investigating if you sell higher-value products and operate in a market where Affirm supports your business.
PayPal Pay Later
PayPal Pay Later may be convenient for businesses that already use PayPal. The availability of installment or deferred-payment options depends on the market, product and transaction. Do not assume that the same features are offered in every country where PayPal operates.
BNPL through payment platforms
Merchants may be able to activate supported BNPL providers through an existing payment platform rather than build a separate integration. Stripe and Adyen document their available payment methods and market-specific options.
Review the official documentation before choosing a setup: Stripe’s BNPL guide and Adyen’s merchant BNPL guide.
Which Businesses Benefit Most from BNPL?
Furniture and home goods
Furniture, mattresses and other higher-value home products can be suitable candidates because customers may spend time comparing options and budgeting for a purchase. Measure whether installment availability improves completed orders enough to offset the additional fee.
Fashion and beauty
BNPL may appeal to shoppers buying clothing, shoes, cosmetics or product bundles. However, returns, exchanges and small average order values can weaken the business case. Test it against actual return rates and contribution margins.
Electronics
Electronics stores may benefit when customers consider more expensive devices or accessories. Compare BNPL’s incremental costs with product margins, warranty expenses, shipping and price competition.
Travel and other high-value purchases
Installment options may be relevant to eligible travel purchases, courses or other considered services. Check provider restrictions, cancellation terms, delivery or service dates, and applicable consumer-finance regulations before offering financing.
Low-margin or low-ticket products
BNPL can be harder to justify when order values are small or margins are thin. Fixed transaction fees may represent a meaningful share of the sale, and the percentage fee can further reduce profitability. Bundling products may improve the economics, but test the effect rather than assuming it will work.
Should Your Business Offer BNPL?
Before implementing BNPL, evaluate your existing checkout performance and estimate how much incremental contribution the new method would need to generate. The following checklist can help structure the decision.
Consider launching BNPL if:
- Your products have sufficient margins to absorb the provider fee.
- Your average order value is high enough for installments to be meaningful.
- Customers request flexible payment options.
- Your target markets are supported by the provider.
- You can measure conversion, profit and returns by payment method.
Be cautious if:
- Your business operates on very thin margins.
- Most orders are small and price-sensitive.
- Refunds or cancellations are frequent.
- The provider’s terms are difficult to reconcile.
- You cannot separate incremental sales from existing sales.
How to test BNPL without committing too much
- Establish a baseline. Record current conversion, average order value, payment fees, returns and contribution margin.
- Start with a limited test. Introduce BNPL to a relevant market or customer segment where practical.
- Track the right metrics. Monitor BNPL adoption, checkout conversion, total margin after fees, refund rates and support contacts.
- Compare incremental profit. Account for shoppers who would have purchased using another payment method anyway.
- Scale only if results justify it. Keep the method if it delivers measurable value after costs, not simply because customers select it.
How to Measure Whether BNPL Is Profitable
The most useful metric is incremental contribution, not gross revenue alone. A store may report higher sales after introducing BNPL but still earn less per order because the payment fee is higher.
Compare these metrics before and after implementation:
- Checkout conversion rate: The percentage of eligible checkout sessions that become completed orders.
- Average order value: Whether customers spend more when using BNPL.
- Contribution margin: Revenue remaining after product costs and variable selling expenses.
- Payment cost per order: Include the BNPL fee and any additional operational expense.
- Return and cancellation rates: Identify whether the payment method changes the economics of fulfilled orders.
- Incremental profit: Estimate the additional profit generated compared with the situation without BNPL.
Frequently Asked Questions About BNPL for Merchants
Do merchants get paid upfront with BNPL?
In many provider-led BNPL arrangements, the merchant receives settlement after an approved transaction, less applicable fees. Timing, reserves, deductions and exceptions depend on the provider’s agreement.
Who pays the BNPL fees?
Merchants commonly pay a transaction fee to offer the service. Depending on the plan, customers may also pay interest or late fees under their financing agreement. The exact structure varies by provider, country and product.
Are BNPL fees higher than credit card fees?
They are often higher than standard card-processing fees, although the actual difference depends on the merchant’s agreement, payment method, region and transaction volume. Compare the complete pricing schedule.
Does BNPL guarantee higher sales?
No. BNPL can improve conversion or average order value for some stores, but results vary. Measure whether the new option generates additional profitable sales after fees, returns and operating costs.
Does the BNPL provider assume all merchant risk?
Not necessarily. Providers often assume agreed customer repayment risk, but merchants may remain responsible for fulfillment, refunds, certain fraud scenarios and contractual exceptions. Read the agreement carefully.
Can small businesses offer BNPL?
Many providers work with eligible small businesses, but approval depends on the provider, merchant country, business model, product category and other underwriting requirements. Check eligibility before integrating the service.
Is BNPL suitable for every ecommerce business?
No. It is more compelling when flexible payments address a real customer need and the extra contribution covers the provider fee. Low-margin businesses should be particularly careful.
Can merchants offer BNPL outside the United States?
Yes, depending on the provider and market. Availability, repayment products, regulations and merchant eligibility vary by country. Confirm that your business registration country and target customer markets are supported.
Final Verdict: Is BNPL Worth It for Merchants?
Buy now, pay later can be a useful checkout option for ecommerce merchants selling higher-value products or serving customers who prefer installments. It can help reduce payment friction, increase order value and reach shoppers who might otherwise leave checkout.
The trade-off is cost. Merchant fees can be higher than standard card processing, and additional sales do not always mean additional profit. Refund rules, integration effort, customer support and local regulations also matter.
Start by requesting written quotes from suitable providers, calculating the impact on your margins and running a measured test. If BNPL increases incremental contribution after all costs, it may be a valuable addition to your payment strategy. If it only shifts existing customers to a more expensive payment method, the extra expense may not be justified.
