"Should I expand to more marketplaces?" We hear this question often. The honest answer: it depends. In this article, we analyse when multi-channel makes sense - and when it doesn't.

The Reality of Multi-Channel

Let's first look at the facts:

Marketplace Market share DE Effort
Amazon ~50% Medium
eBay ~25% Medium
Otto ~8% High
Kaufland ~4% Medium
Other ~13% Variable

Amazon dominates the German market. This means: every euro of revenue on other platforms requires proportionally more effort.

When Amazon Only Makes Sense

✅ Stay with Amazon if:

The 80/20 Rule: Many sellers generate 80%+ of their revenue on Amazon. But the remaining 20% on other channels cost 50%+ of the total effort.

When Multi-Channel Makes Sense

✅ Expand if:

The Most Important Channels at a Glance

eBay

The second-largest marketplace in Germany. Good for:

Challenge: Lower average prices, price-sensitive buyers.

Kaufland (formerly Real.de)

A strongly growing platform with good support:

Challenge: Still lower reach, you organise logistics yourself.

Otto

A premium platform with high requirements:

Challenge: Strict admission requirements, high onboarding effort.

How to Expand the Right Way

Phase 1: Preparation

  1. Document and optimise Amazon processes
  2. Provide product data in a standardised format
  3. Check warehouse capacity and fulfilment options
  4. Plan resources (staff, time, budget)

Phase 2: Piloting

  1. Start with one channel (not all at once!)
  2. List the top 20 products first
  3. 3-6 month test phase
  4. Measure and compare performance

Phase 3: Scaling

  1. Roll out successful products to more channels
  2. Use tools for multi-channel management
  3. Build up central inventory management
Warning: Don't underestimate the effort! Every new channel means: new API, new processes, new customer service, new tax matters.

Conclusion

Our honest recommendation:

  1. Under 500k€ revenue: Focus on Amazon
  2. 500k - 2M€: Check whether expansion makes sense
  3. Over 2M€: Multi-channel probably makes sense for diversification

In the end: one well-optimised Amazon channel beats five poorly maintained marketplaces.
