European Marketplaces: Amazon, Zalando, Allegro, Bol and Otto

Almost every marketplace comparison you will read comes down to headline commission rates, and headline commission is the wrong number. The commission is one line in a stack that includes monthly seller fees, fulfilment, return processing, advertising and payment charges — and in a continent where fashion returns run 40–50%, the return processing line frequently decides whether a category is profitable at all. The top 100 cross-border European marketplaces generated around €216.8 billion in gross merchandise value in 2024/2025, up roughly 10%, and the difference between winning and losing money in that pool is usually arithmetic nobody did.

1. Why commission is the wrong number

Marketplace fees are among the most researched topics in European ecommerce marketing and among the most misunderstood, precisely because the comparison tables that dominate search results list one variable and omit five.

Based on 2026 marketplace fee analysis noting that most guides compare headline commission rates as if they were the only cost, when in practice the stack includes monthly seller fees, fulfilment costs, return processing fees, advertising spend and payment processing charges. Return rate context from the European D2C analysis.

Two marketplaces with identical 12% commissions can differ by twenty points of effective cost once returns, fulfilment and advertising are included. European ecommerce marketing lives or dies on that gap.

2. The fee stack, line by line

Sources: 2026 marketplace fee comparisons based on publicly available fee schedules and official marketplace documentation as of mid-2026. Fees change regularly. Every figure here must be verified against the relevant seller portal before it informs a pricing decision — the sources themselves carry that warning and it is repeated here deliberately.

3. Open versus curated marketplaces

This distinction matters more than commission rates and receives far less attention in European digital marketing planning.

Based on 2026 marketplace analysis distinguishing open marketplaces that let any registered seller list from curated platforms with higher entry requirements. Zalando’s model is described as more curated than Amazon, meaning higher entry requirements but stronger brand positioning once accepted.

The strategic read is straightforward. If your advantage is price and operational efficiency, open marketplaces suit you. If your advantage is brand and product quality, the barrier at a curated platform is working in your favour — it keeps out the competitors who would otherwise compete you down on price.

4. The competition arbitrage nobody takes

Here is the most actionable finding on this page. Allegro attracts around 157.9 million monthly visitors, dominates Poland and is expanding into the Czech Republic, Slovakia and Hungary — and carries the lowest commission range of the major platforms at roughly 4–15%. Reported analysis notes that most international sellers have not yet entered these markets, meaning significantly less competition than equivalent categories on Amazon Germany or eBay.

The same argument applies with more force to Poland itself, where Allegro launched marketplaces in Czechia, Slovakia, Hungary and Slovenia reachable from a single seller account. Kaufland shows a similar pattern: roughly 35 million monthly visitors across Germany, Austria, the Czech Republic, Slovakia, Poland and Romania, with an effective cost-per-sale described as competitive with Amazon while offering lower seller competition in many categories.

Based on reported visitor figures and commentary that most international sellers have not yet entered Allegro’s markets and that Kaufland is one of the less-discussed marketplaces in Western European ecommerce guides. Competitive density assessments are directional judgement rather than measured data.

The reason these platforms are under-entered is that entering them is inconvenient, not that they are small. Inconvenience is the cheapest competitive moat available to a mid-sized seller.

5. Local champions by market

For European performance marketing teams planning channel mix, Amazon is dominant across most of Europe with a presence in Germany, France, Italy, Spain, the Netherlands, Poland, Sweden and Belgium — and third-party sellers now account for a record 62% of all units sold on the platform. But it is not the whole picture, and treating it as such is the most common European marketplace error.

Based on 2026 European marketplace analysis. Note that several of Europe’s strongest marketplaces are EU-native — Zalando from Germany, Allegro from Poland, Vinted from Lithuania and ManoMano from France — which is why a US-derived marketplace strategy transfers poorly.

Zalando specifically operates across more than twenty markets with over 7,000 brand partners and around 121 million monthly visitors, offering the Partner Programme with marketing tools, Zalando Fulfillment Solutions and real-time sales data. For fashion brands that clear its entry requirements, it is the closest thing Europe has to a category-defining platform outside Amazon.

6. Operational traps

Sources: reported marketplace documentation noting Otto does not offer a marketplace fulfilment service; EU VAT guidance on inventory storage triggering local registrations; GPSR compliance requirements for EU marketplace entry. Verify each against current platform and regulatory documentation.

The advertising row deserves emphasis. On marketplaces where visibility is increasingly purchased, advertising is not a growth lever sitting outside the fee stack — it is a cost of being findable, and it belongs in the effective cost per sale alongside commission. Any European performance marketing team modelling marketplace economics without it will systematically overstate margin.

7. Marketplace or own store?

The honest answer for most European digital marketing programmes is both, with a clear division of purpose.

Comparative framework. The payment localisation row is a genuine and underrated marketplace advantage in Europe, where local rails such as iDEAL and BLIK are handled by the platform rather than requiring separate integration.

The sequencing that works is usually marketplace first to validate demand and learn a market’s behaviour cheaply, own store second to capture the repeat purchases that make the economics work. The trap is stopping at step one, because a business whose customer relationships are entirely intermediated has no asset that survives a fee increase.

8. What the DSA changed for sellers

The Digital Services Act, alongside the GDPR and emerging AI regulation, sets standards for marketplace transparency, seller accountability and consumer protection. Reported analysis frames this as making EU market entry more complex but also more trustworthy for buyers.

That trade is worth understanding rather than resenting. Higher verification and accountability requirements raise the cost of listing, which suppresses the volume of low-quality competition that would otherwise flood open marketplaces. For a legitimate brand, compliance overhead functions partly as a competitive filter.

9. What this page does not cover

Scope statement. The first row is the important one: this page is a framework for thinking about marketplace economics, not a fee reference. Sources publishing fee tables carry the same warning.

10. The 90-day plan

Indicative sequencing. Effective cost per retained sale comes first because it is the only figure that lets you compare platforms honestly, and because most sellers have never calculated it.

12. What changes next

Low-price competition is relocating, not leaving. Temu has rapidly captured European traffic share, particularly in the UK and France, and following the July 2026 de minimis change the large platforms are reported to be moving inventory into EU warehouses rather than retreating.

Compliance requirements keep rising. The DSA, GDPR and emerging AI rules continue to raise marketplace transparency and seller accountability standards, which increases entry cost and filters competition simultaneously.

Third-party share keeps growing. With third-party sellers now at a record 62% of Amazon units sold, the marketplace model is becoming more intermediated rather than less — which raises the value of any direct customer relationship you can build alongside it.

Key Takeaways

• Headline commission is the wrong number. Compare effective cost per retained sale across all six fee lines.
• Return processing decides high-return categories, and Europe’s statutory 14-day right makes those categories common.
• Allegro offers 157.9 million monthly visitors at roughly 4–15% commission, and most international sellers have not entered.
• Kaufland reaches 35 million monthly across six markets with lower seller competition in many categories.
• Open versus curated matters more than commission. Curated platforms keep out the competitors who would undercut you.
• Otto has no marketplace fulfilment — you ship yourself, which is an entry requirement rather than a detail.
• Marketplace advertising belongs in the fee stack, not the media plan, because visibility is increasingly purchased.

Frequently Asked Questions

Conclusion

For anyone planning European ecommerce marketing, marketplaces are not a single channel with different logos. They are a set of markets with different entry rules, different competitive density and radically different effective costs once the full fee stack is counted rather than the commission line everyone publishes.

Two conclusions follow. Build the effective cost per retained sale before you list anywhere, because in a continent with statutory returns and high category return rates that number bears little relation to the headline percentage. And look seriously at the platforms whose main barrier is unfamiliarity rather than size — Allegro’s 157.9 million monthly visitors at the lowest commission range in the market are not under-exploited because the opportunity is poor. They are under-exploited because entering is inconvenient, which is the most durable advantage available to anyone willing to do it.
