Consulting and auditing

We build your ERP by plugging specific developments into standard modules through APIs.

Our knowledge of the main ERP standards (Microsoft, Sage, Cegid, Divalto, SAP, Oracle) and value-added solutions (Docaposte Maileva, ABBYY Ocr, DocuSign, etc.) allows us to design an information system that leverages the latest technologies.

In close partnership with Microsoft, we integrate the management system into the Office 365 collaborative working environment.
