Open Mercato vs Symfonia - Comparison 2026

Last updated: March 2026

Symfonia (formerly Sage Symfonia) is a popular Polish accounting and HR system used by thousands of companies in Poland. Its Finance and Accounting, HR and Payroll, and Trade modules are well known among Polish accountants and accounting firms.

The challenge comes when a business needs more than accounting -a modern CRM for sales management, a B2B portal, open APIs for integration, or a browser-based system. Symfonia is built on legacy architecture, does not offer a full CRM, and has limited integration capabilities with modern tools.

Open Mercato is an open-source platform combining CRM, ERP and B2B Commerce. For companies that need an integrated CRM and ERP system without legacy constraints -it is a solution worth considering.
