Accepting Oney as a merchant

Oney provides instalment and deferred payment, strongest in France and southern Europe, typically presented at checkout as paying in three or four instalments. As with every method in this category, the fee prices credit rather than processing.

Market

Instalments in France are a retail convention, not a novelty

Paiement en plusieurs fois is an established French retail expectation, particularly at higher basket values and in categories like furniture, electronics and travel. That maturity matters commercially: French consumers are not being introduced to instalments, they are choosing between merchants who offer them well and merchants who do not offer them at all.

What the fee is actually buying

Oney takes the credit decision and the receivable and pays you up front. You are buying risk transfer, working capital and a collections function, which is why the rate sits well above card acceptance and why benchmarking it against a card rate tells you nothing useful. Benchmark it against incremental revenue and against what carrying the credit yourself would cost.

Basket value is where the case is won or lost

Instalment methods earn their fee disproportionately at higher order values, where the alternative is genuinely no purchase rather than a purchase on a different method. At low basket values the substitution rate rises and the economics deteriorate quickly. Setting a sensible minimum order value for instalment presentation is the single cheapest control available, and most merchants have never set one deliberately.

Which payment provider supports Oney?

HiPay, Payplug, Worldline and Adyen all document Oney instalments, as do the other gateways serving France and southern Europe. The useful questions are the fee as a percentage of order value, the acceptance rate on your customer profile, when you are paid, how returns interact with the instalment schedule, and at what basket value the method stops paying for itself.

Regulation

A retail convention becomes regulated credit on 20 November 2026

Directive (EU) 2023/2225, the second Consumer Credit Directive, repeals the 2008 directive with effect from 20 November 2026, and member states were required to transpose it by 20 November 2025. The exemption for credit repayable within a short period at insignificant cost is removed, which is the exemption interest-free instalment products have relied on. Providers come within the national financial supervision regime, bringing a licence requirement, mandatory creditworthiness assessment, credit register participation, stricter information and advertising rules, and an explicit prohibition on offering deferred payment to minors.

France is where that lands hardest, and not because the rules are different there. It is because paiement en plusieurs fois is not a promotional add-on in a French checkout; it is a normal way to buy a sofa. When a mainstream purchase behaviour becomes a regulated credit product, the volume affected is not a niche at the edge of your reporting. It is a visible share of your French revenue, at exactly the basket values where instalments are worth the most to you.

The part most merchants underestimate is the advertising side rather than the acceptance side. Instalment messaging in a French catalogue does not live only in the payment step. It sits on category pages, on product pages, in price displays and in campaign creative, and all of that is your copy rather than your provider’s. Two questions are worth asking before the date rather than after it: what your provider expects acceptance to do on your own customer profile, and which of your existing pages carry instalment messaging that will need to change.

Instalments

Three instalments or four, and where the method stops paying

Paying in three and paying in four look like the same product with a different number on it. They are not, because the fee usually rises with the number of instalments while the incremental conversion they buy does not rise in step.

Numbers. Take 4 million euros of French revenue with 30 per cent on Oney, so 1.2 million euros across 3,000 orders at an average of 400 euros. Suppose three instalments cost 2.4 per cent and four cost 3.1 per cent, against 0.5 per cent for a card. On 3x that is 28,800 euros against 6,000, so 22,800 euros of extra fee. On 4x it is 37,200 against 6,000, so 31,200. The extra 8,400 euros a year buys one more instalment for the customer.

Whether that is worth it is an empirical question with a cheap answer. Offer 4x only above a basket value where the extra instalment plausibly decides the purchase, and 3x below it. At a 40 per cent gross margin the 8,400 euros is covered by 21,000 euros of genuinely incremental revenue, which is 53 additional orders at 400 euros. If the fourth instalment cannot produce 53 extra orders a year on 3,000, it is being paid for by customers who would have taken three. That test costs nothing to run and almost nobody runs it, because the choice between 3x and 4x is normally made once, by whoever filled in the onboarding form.

Baseline

The other half of the French question

France is one of the few markets where the instalment decision and the card routing decision sit in the same checkout and are usually owned by different people. Most French cards are co-badged, so the card side of your French volume has its own cost lever that has nothing to do with Oney.

That matters when you evaluate instalments, because the comparison you are making is against your effective French card rate, and that rate is itself a variable rather than a given. A merchant who has never examined how French co-badged volume routes is comparing a negotiated instalment fee against an unexamined card cost, and concluding something about the first from a number that belongs to the second. Do the card side first. It is cheaper to fix and it sets the baseline that every other French method is judged against.

Reviewing what this costs you

What you pay is set in your agreement, not by the scheme. Start by establishing whether you are overpaying your PSP, or put your own volume through the PSP Upside Calculator, because this is the method where the distance between a negotiated rate and a standard one is widest.
