ERP Upgrade & Fit-Gap Advisor (Claude plugin)
Choose, plan, cost and upgrade an ERP with sourced facts, not guesses. For French SMEs and mid-size companies evaluating or running Odoo, Microsoft Dynamics 365 Business Central, Sage 100 / X3, SAP Business One, Divalto, Cegid, Sylob or EBP — with a deep Odoo 20 upgrade module built on Odoo 20 release day (24 Sept 2026).
Every vendor fact carries its URL, check date and certainty level (official / third-party / not found). Nothing is invented: unknowns become questions for the vendor.
