Getting onto a marketplace comes down to five steps: choose a platform that fits your product, prepare complete product data and EAN codes, build and optimise listings, set up logistics and returns, then switch on advertising and watch the results. Data takes the most time, so it's the right place to start.
What is marketplace selling and who is it for?
A marketplace is a platform where many sellers offer products in one place, for example Amazon, Allegro, Zalando or About You. The customer arrives on the platform's ready traffic and trust, and you don't have to build your own shop and pull visitors in yourself.
The model makes sense if you have a product ready to sell and want to reach customers faster, including abroad. It doesn't replace your own shop, but it is often the quicker route to the first orders on a new market.
Where do you start when entering a marketplace?
Order matters. These five steps set the process up so you don't have to go back to the start halfway through.
- Pick the platform. Match the marketplace to the product, the audience and the market. One choice fits streetwear, another fits premium fashion.
- Prepare the product data. EAN, names, descriptions, variants, sizing and photos. This is the foundation the listing stands on.
- Build and optimise listings. Titles and descriptions for search on the given market, photos compliant with the platform.
- Set up logistics and returns. Decide who warehouses, packs, ships and handles returns. This drives your lead time.
- Switch on ads and measure. First campaigns and observation: what sells, at what cost and margin.
What product data do you need?
Product data is the most common cause of delays. A platform won't let in a listing that is missing something or doesn't add up. Prepare it before you touch the account.
- EAN codes for every product variant.
- Names and descriptions in the language of the market you enter.
- Size and colour variants and consistent size charts.
- Category attributes, for example material, cut, season.
- Photos in the format and quality the platform requires.

The most common mistakes on a first launch
- Starting with no pricing strategy, so the product has no way to compete.
- Incomplete or inconsistent data that blocks listing approval.
- Photos that don't meet requirements and get rejected by the platform.
- No plan for returns, which in fashion are the norm, not the exception.
- Launching on several platforms at once, before one works properly.
How long does it take and what does it cost?
With data and photos ready, a basic launch on one platform usually takes a few weeks. The cost depends on scope: whether you need a photo shoot, translated descriptions, brand registration and logistics, or only the account setup. The most expensive part is usually your own team's time, which is why many brands hand this part to a partner.
Frequently asked questions
Where do I start when entering a marketplace?
Start with two decisions: which platform fits your product, and whether your product data is ready. Everything else, the account, listings, logistics and ads, follows from those two.
What product data do I need to sell on a marketplace?
At minimum: EAN codes, clear product names, descriptions, size and colour variants, size charts, category attributes and compliant photos. Incomplete data is the most common reason listings get held up.
How long does it take to launch on a marketplace?
With data and photos ready, a basic launch usually takes a few weeks per platform. Brand registration and the first campaigns can run alongside it.
Do I need my own warehouse to sell on a marketplace?
No. You can ship yourself, use the platform's logistics or hand fulfillment to an external partner. Many brands start without their own warehouse.
