Open Mercato vs Microsoft Dynamics 365 — CRM/ERP Comparison 2026
Last updated: March 2026
Microsoft Dynamics 365 is a comprehensive CRM and ERP platform, valued by large corporations for its deep integration with the Office 365 and Azure ecosystem. It's a powerful tool, but also complex, expensive and demanding in terms of specialist resources for implementation and maintenance.
For SMEs, Open Mercato delivers the same core capabilities — customer management, sales pipelines, business process automation — at a fraction of the cost. Implementation takes around 10 weeks instead of many months, and the absence of per-user licence fees means costs don't scale with your team.
Below is a detailed comparison of both systems to help you make an informed decision.
