Buy now, pay later (BNPL): opportunities and risks for SMEs

Picture an online store at the moment of truth: a shopper has filled the cart, reached the payment step, and then paused. Paying the full amount in one go feels like too much, so the cart is abandoned. In Türkiye the classic answer to that hesitation is taksit — paying in installments, almost a reflex on credit cards. Buy now, pay later (BNPL) is a newer version of that same habit, one that can work independently of a credit card: the customer splits the purchase over time, while you, the merchant, usually get paid upfront.

This guide looks at BNPL not from the shopper's side but from the merchant's: how the system actually works for an SME, what it does for conversion and basket size, what costs and risks it carries, where it sits inside Türkiye's installment culture and its still-evolving regulation, how to evaluate a provider, and how to reconcile these transactions in your books. We give no specific rates or amounts — those change constantly; instead we explain the mechanism and the decision logic.

What exactly is buy now, pay later (BNPL)?

At its simplest, buy now, pay later is a financing method that splits a purchase into several parts. The twist is that a provider sits in the middle. The customer takes the product, the provider usually pays you the amount upfront, and then collects the installments from the customer over time. So the party splitting the payment is the customer, while the party that assumes and collects that split payment is the provider.

A few things separate this from a traditional credit-card installment. With card taksit, the transaction runs through the customer's own bank and card; with BNPL, a separate financing product is built into the checkout step. Approval is usually quick, some models reach customers without a credit card at all, and the whole experience is embedded in the moment of purchase. It feels similar to the customer — "take it now, pay later" — but the parties and responsibilities behind the scenes are different.

How BNPL works for a merchant

On the merchant side the flow is surprisingly simple. You integrate a BNPL provider into your checkout; when the customer picks BNPL among the payment options, the provider steps in, runs a quick assessment, assumes the risk, and pays you. From that point on, the installment relationship with the customer is the provider's to manage.

• Integration: you connect the provider to your e-commerce stack or checkout — usually just adding an option alongside your other payment methods.
• Selection: the customer chooses BNPL at checkout and goes through the provider's short approval flow.
• Payout: the provider deducts a service fee and pays you the rest — upfront in most models — while carrying the credit and collection risk.
• Repayment: the customer repays the provider directly on the agreed plan; late payment and collection are the provider's problem, not yours.

The critical detail: the amount that lands in your account is not identical to the order's sticker price — it differs by the provider's cut. Treating that gap as a cost line from the very start makes both pricing and later reconciliation much easier.

Why BNPL appeals to SMEs

The biggest reason businesses reach for BNPL is conversion. A customer who balks when the full price appears at checkout will often complete the purchase when the payment can be spread over time. The same logic lifts basket size: once the payment is split, the shopper is more willing to add a higher-tier product or an extra item.

The second reason is cash flow. Because you are paid upfront, you don't carry the burden of financing an installment sale yourself; the party waiting for the money and chasing late payments is the provider. For a business that struggles with collecting overdue invoices, that means handing off a meaningful chunk of the problem. From the standpoint of healthy cash flow management, making the sale and seeing the money at the same time is a powerful advantage.

The third reason is cultural. In Türkiye installments are already a habit; shoppers actively look for a "pay in parts" option. BNPL meets that expectation with a new choice alongside card taksit, and it works especially well in e-commerce and in selling through conversational commerce channels.

For a merchant, BNPL is really a conversion tool: it makes it easier for the customer to say yes while shifting the payment and collection risk onto someone else's shoulders.

Risks and trade-offs

No tool is free, and BNPL has real costs. The first is directly financial: the provider charges a fee for its service. That fee is the price of the tool; in a low-margin business it can thin your profit noticeably, so it belongs in your pricing from the start.

The second is dependence. Part of your sales now hinges on a third party's decisions: the provider's approval policy, its downtime, and its technical reliability all feed straight into your revenue. If the provider declines a customer or its system goes down, that sale disappears outside your control.

The third is operational: returns and disputes get more complicated. There are now three parties at the table — you, the customer, and the provider — and a refund needs correcting in both your records and the provider's. The customer's expectations around returns and consumer rights don't change, but the back end of the process has more steps.

The fourth is less technical but just as important: reputation and ethics. BNPL can make it easy for a customer to spend beyond their means. Customer over-indebtedness affects both how they see you and how the whole payment method is perceived over time. Presenting it transparently and responsibly is worth more than one short-term sale.

The Türkiye context: taksit culture and evolving regulation

Türkiye is both very ready for BNPL and a market with its own character. Ready, because installments are already part of the culture: card taksit has sat at the center of consumer payment reflexes for decades. Telling a shopper "you can pay in parts" is not a new idea here.

Distinctive, because dedicated "buy now, pay later" products independent of the credit card — and the way they are regulated — are still developing. Consumer credit, payment institutions, and card transactions are all regulated in Türkiye, and where BNPL fits inside those frameworks is still settling, as it is worldwide. The regulator's stance (for instance the BDDK and related legislation) can change over time.

So the practical advice is clear: before you commit to a BNPL model, verify the current rules and the provider's licensing status. Confirm through official sources and your accountant (mali müşavir) whether the provider holds the necessary permits, which regulations it falls under, and what your own responsibilities are. This article explains the mechanism; the exact rule in force should always be checked against a current official source.

How to evaluate a BNPL provider

Providers are not interchangeable; the choice comes down to comparing a few concrete points.

• Settlement terms: when and how do you get paid? How is a refund clawed back? Is the payout upfront or delayed?
• Integration: how easily does it connect to the e-commerce stack or checkout you already use? What's the technical effort?
• Customer experience: is the approval flow fast and transparent? Does the customer clearly see what they're agreeing to? A poor flow undoes the conversion you just won.
• Licensing and compliance: does the provider hold the necessary permits, and under which regulation? This matters for both legal safety and reputation.

Putting these four side by side and comparing a couple of providers helps you pick the one that fits your business — not simply the most visible one.

When BNPL fits your business — and when it doesn't

BNPL isn't the right tool for every business. It helps most with considered, higher-ticket purchases, in e-commerce where cart abandonment is high, and in categories where the customer wants to spread the payment out.

By contrast, on very low-margin products the provider's cut can eat the profit; on small, impulse purchases the added step creates needless friction; and where your customers already comfortably use card taksit, BNPL adds limited extra value. The decision should rest on "what is my customer's payment behavior" rather than "a competitor is doing it."

Reconciling BNPL transactions into your books

The most overlooked side of BNPL is the accounting. Remember: the amount that reaches your account is not the same as the order price; the difference is the provider's fee. So every BNPL sale means tracking two separate numbers: the amount on the document issued to the customer, and the amount you actually collect. If you don't record that gap as an expense line, your books won't match your real revenue.

In practice the work comes down to matching the settlement statements the provider sends you against individual orders. Marking which order was paid via BNPL, and when and how much net actually arrived, keeps month-end reconciliation clean. Done by hand this is error-prone; as in a payment-link collection flow, automatically tying each payment to its order and customer record is far safer.

Frequently asked questions

In the end, buy now, pay later is not a magic growth lever but a strong conversion tool when used carefully: it gives the customer flexibility, brings you the money upfront, and hands off collection risk — while creating a cost, a dependency, and extra work on the accounting side. Once you've chosen the right provider, the invisible half of the job is reconciliation; in a system like Rocketly, keeping payment-link collections and pre-accounting records in one place lets you tie each BNPL transaction to its order and customer, keeping your books aligned with your real revenue.
