- Audit depth varied with the workload
- Declined merchants were followed up from memory and often lost

merchant revenue gained per year, modelled
Onboarding a merchant onto a marketplace means verifying that the shop is real and legal, that its product data meets the platform's standards, and that customers can trust what they will see.
Done manually, it is hours of specialist work per merchant.
The follow-up was the weak point: a declined merchant who fixed their shop three weeks later was activated only if someone remembered to look.
Every merchant waiting to be onboarded is revenue standing still, and every declined merchant nobody follows up with is revenue lost for good.

After Duvo
Duvo has been an amazing partner in this journey so far. We are glad to partner with Duvo on our AI transformation and it's really exciting to see how quickly it spreads across the company and adds value.

Product Leader, Heureka
Audits the shop and the feed
Duvo runs the complete compliance audit on every new merchant: the shop, the legal requirements, and the product feed, against the marketplace's full rulebook.
Prepares the decision
It reaches a decision and hands it to the onboarding specialist, who validates it instead of performing the checks.
Answers the merchant
The merchant receives a clear answer with a concrete list of anything to fix.
Recovers declined merchants
Duvo reminds declined merchants, re-checks their corrections, and activates them the moment they qualify, or closes the case cleanly if they never respond.
Evidence status
Measured result with modelled impact
The ~60 shops a week, the full-rulebook audit on every merchant, and the automatic recovery of declined merchants are customer-approved claims from the pattern proven on the Czech and Slovak platforms, which the Hungarian deployment replicates. The €50–150K/yr of merchant revenue gained is modelled as an incremental share of the ~€1–2K/yr of platform value an active merchant represents: a few days of earlier earning for each of the hundreds of merchants activated every month, plus the full year for the recovered merchants who would otherwise never have gone live. The €50–70K/yr of specialist capacity returned is modelled at full volume.
