You stay the brand.
We become the seller.
Operator One signs the marketplace contracts and invoices the shopper. O1 is the legal seller across the EU and the UK, with the entity, the VAT numbers, the consumer-law liability and the return obligation. We also handle the EU compliance stack (VAT, EPR, DAC7, GPSR) and act as the GPSR Responsible Person when we're your Importer of Record. You ship to one warehouse, sign one master agreement, and get one monthly settlement. That's the whole product.
How Merchant of Record actually works.
A short walkthrough of what Operator One does when a brand signs the MoR engagement — who's named on the invoice, what stays with the brand, and how the compliance stack (VAT, GPSR, EPR, DAC7) gets absorbed into one master agreement. No deck, no pitch.
- What changes for the brand on day one — and what doesn't
- How one entity covers 27 EU + UK marketplaces
- Where the brand stays the owner: IP, listings, reviews, customer relationship
- What happens at the end of the engagement (we hand everything back)

A few of the many operations + back-office burdens we manage for you.
The lane below shows a sample — the real list is longer, and it grows with every marketplace, country and regulation. You stay in control of the brand and the strategy. We manage the execution so your team gets three things that compound: focus on the product, scalability across markets, and the growth that follows when both work together.
- Marketplace management
- EU + UK VAT (OSS, IOSS, our numbers)
- Customer relationship
- EPR & DAC7
- Fulfilment & logistics
- GPSR Responsible Person (when O1 is IoR)
- Content & advertising
- Consumer-law liability
- Returns & customer service
- Disputes & marketplace cases
- IT & integrations
GPSR Responsible Person follows the importer — O1 holds the role when we're your Importer of Record. Specific responsibilities are set in your master agreement.

The moat is operational. Boring. And ours.
A great marketplace operator is a logistics company that runs a software company that runs an AI lab that runs a customer-service team — and a content team, a PIM team and a compliance team behind it. We're all of it. On purpose.
