Gambio

Gambio is a Bremen-based ecommerce platform run by Gambio GmbH, serving around 25,000 online shops in Germany from founders who started out running a shop themselves.

The Cloud product is priced on a mix of a flat monthly fee and a transaction fee that falls sharply as volume grows: Starter costs €29 a month with a 1.5% fee above €500 of free monthly volume, while Enterprise costs €219 a month but drops the fee to 0.1% above €50,000. A self-hosted GX edition is also available for merchants who want to run their own infrastructure.

That transaction-fee taper is unusual among the platforms in this list — most price on a flat plan or per user, not on a percentage that shrinks with scale — so a very small shop can start cheaply while a growing one is rewarded rather than punished for succeeding. A 30-day trial is available before committing, and design tools, multichannel connectors and admin accounts scale with the tier, from one admin on Starter to unlimited on Enterprise.

The trade-off is that Gambio's fee structure still ties part of the bill to what a shop sells, unlike the flat licences PrestaShop or Shopware charge, even if the percentage is far below what Shopify or Wix would take at the same volume. It is also a German-market product first: support, documentation and the merchant base are concentrated there, which matters less for a domestic shop than for one selling across several European countries from day one.

What Gambio does well

• 30-day free trial
• Transaction fee falls from 1.5% to 0.1% as volume grows
• Cloud or self-hosted GX edition
• German company with 25,000+ shops on the platform
• Design and multichannel tools included at every tier

Where Gambio falls short

• Transaction fee still applies on the cloud plans
• Fewer admin accounts on the entry tier
• German-market focus outside DACH
• Not open source in the cloud product

Standout feature. A transaction fee that shrinks with volume instead of a flat licence — the opposite pricing shape from most of this list.
