Opendsi is a French technology consultancy that helps small and medium-sized businesses, mid-sized companies, and public organisations build coherent, manageable information systems. Rather than starting with a software product, the company first works with leaders and IT teams to understand their needs, assess existing tools, and make informed decisions. Its approach covers implementation and ongoing support, with an emphasis on long-term continuity, data control, and reduced dependence on software publishers.

Opendsi’s open-source offering includes Dolibarr-based business management and ERP solutions, including its Osden (Dolibarr Premium) service; Nextcloud for collaboration and file sharing; Metabase for data reporting and organisational insight; and n8n for automation. These tools are positioned as connected parts of an organisation’s operations, helping reduce software silos and make business data more useful for decision-making. Opendsi also provides guidance on electronic invoicing requirements, including assessing Dolibarr readiness for the 2026 reforms. The company serves both private-sector organisations and public bodies, and is a Nextcloud partner with experience dating from 2019.
