Product Onboarding for Marketplaces

Getting products accepted by a marketplace is where most launches stall. We take care of category mapping, attributes, content and compliance so your catalogue goes live fast and stays live.

What you get

Category & attribute mapping

Your product data mapped to each marketplace's category tree, size charts, colours and mandatory attributes.

Content that converts

Titles, descriptions and images optimised to each channel's rules and search, in the right languages.

Compliance built in

Product safety and regulatory data, such as GPSR information, captured once and delivered where each channel requires it.

Quality checks

Error reports from marketplaces are analysed and fixed at the source, not patched listing by listing.

Where onboarding usually goes wrong

Every marketplace has its own data model. What works on your shop is rarely enough for Zalando, Otto or Amazon: different category trees, different mandatory fields, different value lists. Without a clean mapping, teams end up fixing rejected listings one by one, every season.

A process you can repeat

The goal is not only to get the first range live but to leave you with a repeatable onboarding process: documented mappings, clear data requirements for your buying and content teams, and error handling that points to the root cause.

How it works

  1. 1

    Catalogue audit

    We review your product data against the target marketplaces and list what is missing or wrong.

  2. 2

    Mapping & enrichment

    Categories, attributes and values are mapped; missing data is enriched with your team.

  3. 3

    Test upload

    A pilot range is uploaded, errors are analysed and the mapping is refined.

  4. 4

    Full rollout

    The full catalogue goes live, with a repeatable process for new products and seasons.

Frequently asked questions

Why do marketplaces reject my products?

Usually because of missing mandatory attributes, values that don't match the marketplace's lists (sizes, colours, materials), wrong categories or image requirements. Fixing it at the mapping level stops the same errors from coming back.

Can you help with fashion and size mapping?

Yes. Fashion onboarding for marketplaces like Zalando and Otto, including size charts, colour families and material composition, is one of our core areas of expertise.

Do you write the product content?

We define and optimise the structure and rules for titles and descriptions per channel, and can enrich content with your team or with AI-assisted workflows reviewed by humans.
