Buy Now, Pay Later for Online Stores: Pros, Cons and Setup

Buy now pay later in ecommerce lets a shopper split the cost of an order into several smaller payments, often without interest, while the store receives the full amount up front from the provider. For the store, it can mean more completed orders and larger baskets, especially on higher-priced items. It also carries a fee on each sale and responsibilities towards customers who may borrow more than they should. Whether it is worth adding depends on your prices, your margins and your customers.

How buy now, pay later works

When a shopper chooses a BNPL option at checkout, the provider runs a quick check and, if approved, agrees to lend them the order value. Common arrangements include:

• Pay in instalments: the total is split into a few equal payments, often fortnightly or monthly, sometimes interest-free.
• Pay later: the full amount is due after a set period, such as 14 or 30 days.
• Longer financing: larger purchases spread over many months, usually with interest.

From the shopper's side, the experience is usually quick: a few details, an instant decision and a confirmation of the payment schedule.

The store ships the order as normal. The provider pays the store, usually within a few days, minus a merchant fee. The provider then collects payments from the shopper. If the shopper does not pay, the provider normally bears the loss rather than the store.

Why stores offer it

More completed orders

Some shoppers can afford a purchase over a few weeks but hesitate to pay all at once. Seeing a smaller instalment amount on the product page can tip the decision, especially for higher-priced items.

Larger baskets

When the cost is spread out, some shoppers add more to the order. A smaller visible instalment makes the total feel more manageable.

Attracting particular customers

Younger shoppers in many markets are comfortable with BNPL and may look for it. Some providers also run shopping apps and directories that send their users to participating stores.

No repayment risk for the store

Because the provider pays you and collects from the customer, you are not chasing unpaid instalments. That is different from offering your own payment plans.

The costs and downsides

• Higher fees. Merchant fees for BNPL are often noticeably higher than standard card fees. On low-margin products, they can wipe out the profit on the sale.
• Refunds and returns. Returns must be processed through the provider, which then adjusts the customer's plan. Make sure your team knows how.
• Customer debt. Some shoppers take on more than they can manage across several BNPL services. Pushing BNPL hard can harm customers and your reputation.
• Checkout clutter. Too many payment logos and messages can confuse rather than help.
• Regulation. Rules for BNPL are evolving in many countries, which can change how you are allowed to advertise it.

There is also a brand question. Some premium brands worry that heavy instalment messaging makes their products look less exclusive. If that matters to you, keep BNPL messages small and factual, and let the product lead.

Do the sums before you start. Work out the fee on a typical order and compare it with your margin, then estimate how many extra orders would be needed to cover it.

Which stores and products it suits

For B2B stores, invoice payment on credit terms usually serves the same purpose better. Our guide to B2B ecommerce portals explains how trade payment terms work online.

Adding buy now pay later to ecommerce checkout

Choose a provider

Compare providers on the markets they cover, the payment plans they offer, their fees, how quickly they pay you, their approval rates and how well they integrate with your platform. Many payment gateways now include BNPL options in their standard package, which keeps everything in one place.

Show it early

Shoppers are most influenced when they see the instalment amount while deciding, not at the final step. Most providers offer small messages for product pages and the cart, such as "or 4 payments of…". Keep them discreet and accurate.

Keep checkout clear

Show BNPL as one of the payment choices, with the provider's logo and a short line explaining the plan. Do not make it the default option or hide other methods behind it.

Train your team

Customer service staff will be asked about refunds, missed payments and plan changes. Most of these are handled by the provider, but your team should know where to send customers and how to process returns correctly.

BNPL is one part of a strong checkout. Our guide on how to reduce cart abandonment covers the other payment and checkout factors that affect whether shoppers complete their orders.

Offering BNPL responsibly

BNPL is a form of credit, and some customers struggle with it. Offering it responsibly protects them and protects your brand.

• Be clear: show the total cost, the payment schedule and that it is a credit agreement.
• Avoid pressure: do not use language that suggests the product is cheaper than it is or that urges people to spend more.
• Follow the rules: regulators in several countries have introduced or proposed rules on BNPL, including how it can be advertised. The UK Financial Conduct Authority, for example, publishes guidance for consumers on buy now, pay later, which shows the concerns regulators focus on.
• Use the provider's approved wording in adverts and messages, which is usually written to meet local requirements.

Measuring whether it pays

After launch, track:

• The share of orders paid with BNPL.
• Average order value for BNPL orders compared with other methods.
• Checkout conversion before and after launch, for comparable periods.
• Total BNPL fees as a share of BNPL revenue.
• Return rates for BNPL orders.

Be careful with cause and effect. Shoppers who choose BNPL may have bought anyway with another method. The clearest test is whether overall conversion and revenue rise after you add it, not just whether some customers use it.

Review regularly

Fees, providers and regulations change. Review your BNPL setup at least once a year, compare providers again and check that your messaging still meets current rules.

BNPL in different markets

BNPL is popular in many regions, but the providers and expectations vary. In some European countries, invoice-based "pay later" options have been common for years. In the United States and Australia, instalment plans are widely used at online checkouts. In the Gulf region, regional providers have grown quickly, especially for fashion and electronics. If you sell internationally, choose a provider, or a payment gateway, that supports the local options in each market you serve. Our guide to selling online in Europe covers local payment preferences in more detail.

Matching the provider to your audience

Shoppers recognise and trust the providers they already use. A brand that is familiar in one country may be unknown in another, so check which names your customers know before choosing. Some stores offer two providers to cover different markets or order sizes.

Common mistakes with BNPL

Stores that are disappointed with BNPL usually made one of a few avoidable mistakes:

• Adding it without checking margins. A product with a slim margin can become unprofitable once a higher payment fee is applied. Some stores set a minimum order value for BNPL to protect small orders.
• Hiding it until the last step. If shoppers only see the option at payment, it cannot influence the decision to buy. The product page message is where much of the benefit comes from.
• Overloading the page. Several BNPL banners, badges and pop-ups on one product page distract from the product itself and can look desperate.
• Forgetting returns. If refunds are processed outside the provider's system, customers may keep being charged for items they returned. That leads to complaints aimed at your store, not the provider.
• Ignoring the customer experience. Some providers handle missed payments more gently than others. Read reviews of the provider from the customer's side, because their experience reflects on you.
• Never reviewing it. A provider chosen years ago may no longer offer the best fees, coverage or approval rates.

A short test period helps. Add BNPL for a few months, measure the effect on conversion, basket size and margin, and then decide whether to keep it, change provider or adjust where it appears.

Mind the mobile experience

Most BNPL purchases happen on phones. Check that the provider's approval screens load quickly, work in your shoppers' languages and return them cleanly to your order confirmation page. A clumsy hand-off between your checkout and the provider's screens can lose the very orders BNPL was meant to win.
