## Challenge
Dayes had just created its Amazon Vendor business and was running it by hand: no processes, no KPIs, a catalogue that had never been optimised, and no advertising or operational expertise in the building. Vendor is unforgiving of that, because rejected purchase orders, shortages, chargebacks and slipping lead times quietly erode margin before any report explains why.

## What changed under Operator One
- Operator One runs the brand's own 1P Amazon vendor business across the European markets: strategy, operations, listings, catalogue and advertising.
- O1 also acts as Merchant of Record where the brand sells direct, so both routes to market sit with one partner.
- Documented procedures replaced manual work, each with a KPI attached, so vendor performance became measurable.
- The catalogue was rebuilt for consistency across four markets and extended with around 150 new products.
- Advertising is run for efficiency, with spend deliberately pulled back after peak events while organic sales kept growing.

## Outcome
Vendor revenue more than tripled in the first full year, with purchase-order acceptance up 40%, chargebacks down 80%, shortages down 30% and lead time down 30%.

## Who this applies to
If your vendor business grew faster than your processes, the fix is an operating model rather than more people. And if you sell direct as well, both channels can sit with one partner. Book a call to see how the two fit together.

## Story
Vendor and Merchant of Record, run by one partner Dayes sells across pet care, home care, personal care and cleaning. The company had just stood up an Amazon Vendor business, and the ambition for it was serious. The operating model behind it did not exist yet. The problem The vendor unit was being run by hand. There were no documented processes, no KPIs, a catalogue that had never been optimised, and no advertising or operational expertise in the building. Vendor punishes that quickly. Purchase orders get rejected, shortages and chargebacks accumulate, and lead times slip. Each of those quietly erodes margin, and without measurement nobody can see which one is doing the damage. Meanwhile the direct selling channel needed a different setup again, with its own legal and compliance requirements. What Operator One put in place Operator One took over the Amazon EU vendor operation end to end: strategy, operations, listings, catalogue and advertising, run on the brand's own 1P account. Alongside it, O1 acts as Merchant of Record where the brand sells direct, becoming the legal seller and carrying the compliance on that side. Both routes to market now sit with one partner rather than being managed separately. The first structural change was replacing manual work with documented procedures, each with a KPI attached, so performance became something you could see rather than something you inferred. The catalogue was rebuilt for consistency across four markets and extended with around 150 new products. Advertising is run for efficiency, with spend deliberately pulled back after peak events while organic sales kept growing. Where the brand stands now Vendor revenue more than tripled in the first full year. Purchase-order acceptance up 40%, chargebacks down 80%, shortages down 30%, lead time down 30%. Around 150 new products live, with consistent listings across four countries. Vendor support and Merchant of Record running together under one partner.
