Open Mercato vs enova365 - Comparison 2026

Last updated: March 2026

enova365 by Soneta is one of the most popular Polish ERP systems, valued for its solid accounting, payroll and fixed-asset modules. Thousands of Polish companies rely on it for daily financial and HR operations -and for good reason, as it is a proven tool for these tasks.

The challenge comes when a business needs a modern CRM, a B2B ordering portal for partners, open APIs for integration, or a browser-based system without Windows installation. enova365 does not offer a full CRM or B2B portal -it requires purchasing additional modules or third-party tools.

Open Mercato is an open-source platform that combines CRM, ERP and B2B Commerce in a single system. For companies that have outgrown enova365 in sales and customer relationship management -it is the natural next step.
