European Alternatives to Square

Square is widely used, but organisations across Europe are increasingly looking for alternatives that offer genuine GDPR compliance without the legal uncertainty of US data jurisdiction. The European market now offers 3 mature alternatives to Square that match core functionality while keeping your data exclusively under European law.

The alternatives listed below are all headquartered in Europe, store data within EU/EEA data centres, and offer Data Processing Agreements aligned with GDPR Article 28. Several are open source, giving you additional transparency and flexibility that proprietary US services cannot offer.

Switching from Square to a European alternative is typically straightforward. Under GDPR Article 20, you have the right to data portability — Square must allow you to export your data in a machine-readable format. Most European providers offer import tools or migration guides to help you transfer your data with minimal downtime.

For small teams, migration can often be completed in a single day. Larger organisations should plan for a phased rollout over one to four weeks, starting with a pilot group to identify any workflow adjustments. The most common challenge is not the data migration itself, but updating integrations and retraining team members on the new interface.
