BNPL’s Real Test Starts at the Point of Sale

Radi El Haj argues that as the UK’s new Buy Now Pay Later rules take effect, providers that embed affordability checks directly into the transaction flow, rather than as a separate step, will protect conversion, build the audit trails regulators expect, and turn compliance into a genuine competitive advantage.

The UK’s new regulatory regime for Deferred Payment Credit – the interest-free products most consumers know as Buy Now Pay Later – came into force on 15 July, and anyone still calling that a shock hasn’t been paying attention. The Woolard Review told the FCA to bring these products inside the perimeter as a matter of urgency in February 2021, when the market had just quadrupled to £2.7 billion.

It has since grown past £13 billion, used by around 11 million people. The direction has been fixed for five years; only the deadline arrived this month.

I will take the compliance summary as read. Providers now owe borrowers proportionate affordability assessments, the Consumer Duty, access to the Financial Ombudsman Service, and Section 75 protection on higher-value purchases. The question worth asking isn’t what the rules say but where, in the flow of an actual transaction, a firm chooses to satisfy them.

Why the Transaction Flow Is Where This Gets Decided

That choice matters more than the wording of the new rules, because deferred payment credit is defined by its position in the journey. It is credit, taken in a handful of instalments, decided in the second between a shopper choosing an item and paying for it and its commercial value is the absence of friction at exactly that second.

An affordability check placed as a discrete step, a screen the customer has to reach, wait on and clear, puts friction back at the one point the model cannot absorb it. Embedding proportionate affordability decisioning within the transaction flow, supported by appropriate real-time data, can minimise unnecessary friction while still producing the evidence and controls required of a regulated lender.

The UK has run this experiment before under a different name. When PSD2 made Strong Customer Authentication mandatory, firms that bolted a challenge screen onto checkout paid for it: transactions pushed through a 3-D Secure challenge abandon at rates ten to twenty-five per cent higher than those routed around one through good data and exemptions.

The firms that treated authentication as an engineering problem – using richer transaction data so that challenges occurred only where necessary – were better able to protect conversion while meeting the new requirements. Affordability decisioning under the BNPL regime rewards and penalises the same instincts.

The Regulatory Case for Building Properly

There is a further reason to build this properly rather than minimally, which is that the UK isn’t the only market moving. The EU’s revised Consumer Credit Directive pulls BNPL into consumer credit rules across the bloc and applies from 20 November this year, with creditworthiness obligations that look a great deal like the FCA’s. The regulatory distance between the two markets is closing rather than widening.

A provider engineering affordability and regulatory controls into its core infrastructure now is building for both regimes and creating an architecture that can adapt as it enters additional markets.

It is worth stating plainly that the regulation is a commercial opportunity for firms that respond to it well. BNPL has carried a reputation for nudging people into debt they hadn’t registered they were taking on, and that reputation has capped its standing with cautious consumers, cautious merchants and cautious boards.

Section 75 rights, which apply to purchases above £100 and therefore above the value of a typical basket, together with a route to the ombudsman, give the product the kind of assurance people already expect from a credit card. That assurance widens the addressable market rather than shrinking it, and the benefit accrues to providers who can show they lend responsibly, not to those who merely say so.

What the Infrastructure Has to Deliver

Showing it is where the infrastructure bill lands. Real-time decisioning therefore moves from being a competitive advantage towards becoming an increasingly important part of operating regulated BNPL efficiently at scale. Complete and reconstructable audit trails start to matter more than most BNPL businesses are used to, because a regulator entitled to ask a firm to evidence a specific affordability decision is a regulator that will eventually ask.

Advisers have already flagged data integrity as the real pinch point: many BNPL models were never built to produce regulatory-grade management information, and gaps in data lineage and definitions that an unregulated lender could live with turn into findings once it is authorised.

The BNPL stack also needs to be integrated into the wider payments infrastructure rather than sitting alongside it, allowing affordability, fraud, risk and settlement to be orchestrated around a consistent view of the customer and transaction.

None of this is an argument for retreat. The firms that will struggle are those treating Regulation Day as a line to survive rather than a specification to design against. The ones that pull ahead will be those that embed affordability, transparency and redress into the transaction cleanly enough that customers experience BNPL as a more trustworthy product, not a slower one.

That is harder to build, but it is where the competitive ground will be won. BNPL’s next phase will not be defined simply by who can offer credit at the point of sale, but by who can combine responsible lending, intelligent decisioning and frictionless payments within the same transaction.
