## Challenge
For an enterprise brand with its own systems and a deep catalogue, the marketplace bottleneck is not ambition or demand, it is integration. Product data, stock and prices live in the brand's own stack, and orders have to come back into it. Without that plumbing, marketplace scale depends on manual work that does not scale, and a catalogue that size is not discoverable on its own.

## What changed under Operator One
- Operator One built an API-first integration, so products, stock and prices flow automatically from the brand's own systems into the marketplace operation.
- Orders and shipment confirmations flow back, closing the loop so the brand's systems stay the single source of truth.
- Operator One runs the brand's marketplace advertising across its countries: campaign structure, budget management and optimisation per market.
- The setup is built for catalogue depth, so an enterprise range stays live and accurate without a person in the middle.

## Outcome
The marketplace operation runs on an automated connection to the brand's own systems, with advertising managed across every country.

## Who this applies to
If your catalogue lives in an ERP and your marketplace plans depend on someone exporting spreadsheets, the integration is the project. Book a call to see what connecting your systems would involve.

## Story
Integration first, then advertising at scale Trotec makes climate solutions and tools: dehumidifiers, heaters, air purifiers and measuring devices. It is an enterprise business with its own systems and a catalogue deep enough that no one is going to maintain it by hand. The problem For a brand at this size, the marketplace bottleneck is not ambition and it is not demand. It is integration. Products, stock levels and prices live in the brand's own stack, and orders have to come back into that same stack to be fulfilled and accounted for. Anything that breaks the loop creates manual work, and manual work does not scale with a catalogue this size. There is a second problem behind the first. A deep catalogue is not discoverable simply because it exists. Being listed and being found are different things, and for ranges with this many products the difference is decided by advertising. What Operator One put in place Operator One built an API-first integration for the brand's marketplace layer. Products, stock and prices flow automatically out of the brand's own systems and into the marketplace operation, and orders and shipment confirmations flow back the other way. The loop is closed, so the brand's systems remain the single source of truth and nobody sits in the middle re-keying data. The second half of the engagement is commercial. Operator One runs the brand's marketplace advertising across its countries: campaign structure, budget management and per-market optimisation. That is what turns a large, accurate catalogue into one that customers actually reach. Where the brand stands now An automated connection between the brand's systems and the marketplace operation. Orders and shipment confirmations flowing back into those systems. Advertising run and optimised country by country. A deep catalogue kept live and accurate without manual maintenance.
