## Key takeaways
- More than 48,000 merchants across five European markets have taken a Wero payment, but most still run cards alongside it.
- Wero's fee edge is real on small domestic baskets where fixed rates apply, and it fades on higher-value, cross-border or credit-heavy volume.
- Cards still win on the part buyers don't see: a chargeback and protection framework that is familiar, guaranteed and already understood.

More than 48,000 merchants have already taken a Wero payment. That number is real. It does not mean the acceptance setup most of them already run with cards has been rewritten.

EPI put the figure out in mid-September. It covers Belgium, France, Germany, Luxembourg and the Netherlands, online and the first in-store transactions. Two years after starting as a peer-to-peer tool on the French Paylib base, Wero is no longer background noise. Merchants are starting to ask a narrower question: on which part of their volume does it actually improve the economics and the operations they already have with cards?

## Where it is

In France the online rollout began in September. Orange opened it first for Sosh subscription bills, and Air France, Decathlon and Fnac Darty have confirmed their adoption. In Germany it is already live for online payments at merchants including Decathlon, dm, Eventim and Lidl.

In-store coverage is thinner. Belgium has taken its first in-store steps with a QR code on Payworld terminals, and Luxembourg moved to the full range of use cases in September. Broader point-of-sale availability in France and Germany is planned progressively from 2027.

EPI says Wero now serves around 60 million users across the core markets. The [European Network for Payments](https://epicompany.eu/media-insights/european-network-for-payments), announced on 30 September with Bancomat, Bizum, MB WAY and Vipps MobilePay, creates an interoperability layer serving roughly 130 million users across 13 countries. Cross-border person-to-person comes first. E-commerce and in-store follow later.

This is real infrastructure. It is not yet a full alternative to cards.

## The fee

Wero is account-to-account. There is no traditional interchange. EPI describes pricing as a small percentage fee with built-in caps. No single public scheme rate exists. Merchants get their rate from their bank or PSP, which adds its own margin.

Provider list rates give a clearer view. [Mollie](https://www.mollie.com/payments/wero) lists domestic Netherlands at €0.32 fixed and domestic Belgium at €0.39 fixed, with 0.90% + €0.25 for all other countries. Other providers show fixed amounts in the €0.17–€0.40 range for domestic Netherlands and Belgium, and percentage-plus-fixed structures elsewhere. These are list rates. Contract pricing varies with volume.

Against a typical EU consumer card rate of 0.7–0.8%, the current domestic fixed rates can still produce a difference, especially on smaller baskets. On a €50 sale a €0.32 fixed fee is lower than 0.8%. On higher baskets the advantage depends on whether the rate stays fixed or moves to a percentage. Cross-border or non-core volume priced at 0.90% + €0.25 sits closer to, or sometimes above, a competitive card rate.

In [the Netherlands](/payments/nl) and Belgium the picture is transitional. EPI has committed that scheme pricing will remain broadly aligned with current iDEAL | Wero levels until the end of 2028. After that the model moves further toward percentage-based pricing with caps. Dutch merchants and analysts have already noted the risk that a shift from the historically fixed iDEAL pricing to percentage-based pricing could raise costs on higher-value baskets. No percentage has been published for the period after 2028, and the level and the form of the promised cap are not public either. The comparison is not automatically better in markets that already had strong, low-cost local account-to-account schemes.

## What sits next to the fee

The larger open question is what happens after the payment. Cards carry established chargeback, fraud and protection frameworks that both buyers and merchants understand. Wero has built a structured dispute process, but the rules, timelines and liability differ, and some commercial protections are still phased.

Wero is not a guaranteed payment method in the card sense: a completed payment can be reversed. A consumer raises a problem with the merchant first, as a pre-dispute, then escalates to a formal chargeback with their bank if it is not resolved. Providers such as [Mollie](https://help.mollie.com/hc/en-us/articles/37606121753618-How-to-handle-Wero-disputes) document four stages: pre-dispute, chargeback, pre-arbitration and arbitration by the scheme. Eligible reasons include processing errors, certain fraud claims, item not received, and item not as described. Some merchant categories are exempt from commercial disputes. In the Netherlands commercial disputes are delayed until 1 January 2028; in France until 1 November 2027. Fraud and processing-error claims remain available earlier.

This is not the same as pure iDEAL, where payments were final once processed and the scheme offered no chargeback path. Dutch analyses of the migration have described the shift as a transfer of financial risk: revenue is no longer automatically final, and the acquiring PSP ultimately carries the residual risk if a merchant cannot cover a chargeback. That can translate into stricter onboarding, reserves, delayed settlement or higher fees for some merchants.

Operational costs follow. Merchants face deadlines to respond, often seven days at the pre-dispute stage. Missed windows produce automatic losses. Dispute fees apply when cases are accepted, lost or refunded after opening. The additional labour of gathering evidence is real. So is the risk of friendly fraud on non-delivery or not-as-described claims. Compliance programmes that monitor excess dispute and fraud ratios can impose further fees or restrictions.

Refunds themselves are not automatic. Consumers are directed to contact the merchant first. Only if that fails do they escalate inside the Wero app. The process works, but it is slower and more manual than the familiar card path for many buyers. Fraud risk also remains. Strong customer authentication reduces it, yet account takeover and social engineering still produce unauthorised transactions that can be reversed after goods have shipped.

Payout timing does not improve the cash-flow picture either. Because the payment still runs through an acquirer, the money lands first on the acquirer's account and is then paid out to the merchant. It does not arrive faster than a normal [card payout](/glossary/payout).

## The equation that remains

Wero can lower the fee line on a portion of domestic European volume where current fixed rates apply and average order values are not high enough to erase the gap. That is a real change for merchants whose mix is mostly domestic and whose baskets are not large.

It does not yet change the equation for the rest of the volume. International traffic, credit-heavy traffic, higher-value goods and categories with elevated dispute or fraud risk still favour cards, because the protection framework is more familiar to buyers and the operational path is better understood. In-store coverage remains limited outside early Belgian QR use, so the physical acceptance equation is largely unchanged until broader POS rollout from 2027.

Buyer adoption faces the same gaps. Cards, and the wallets that sit on them, already offer one-tap familiarity and a clear path when something goes wrong. Wero's protection exists but is newer, phased in places, and requires more steps from the consumer. Until that experience matches or exceeds what buyers already trust, conversion will lag even when the merchant fee is lower.

Most merchants will keep cards and add Wero where the fee difference is clear and the operational overhead is manageable. The ones who measure both the rate and the real cost of refunds, disputes and support on their own mix will see whether the net equation improves. Those who look only at the headline fee will not.
