OpenConcerto is an open-source, modular ERP and accounting suite developed by ILM informatique. It brings core business functions—general ledger, invoicing, sales and purchasing, inventory management, CRM, and point of sale—together in a single, customizable platform. The cross-platform desktop application uses a relational database backend and supports multi-user, multi-company setups with role-based permissions, audit trails, and comprehensive reporting.
Organizations can adapt OpenConcerto to their workflows by configuring screens, forms, and print layouts, and by extending capabilities through optional modules and integrations. Built-in tools for data import/export, dashboards, and analytics help teams monitor performance and make informed decisions.
Designed for small and mid-sized businesses, OpenConcerto combines the flexibility of open source with the practicality of a turnkey solution. Companies can self-host and manage it in-house, and they can access professional services, training, and long-term support from ILM informatique.
