Finance Where I'm From: What French SMBs Actually Get Wrong When Consolidating SaaS Tools Into a Dynamics 365 + Power Platform Ecosystem

Most French mid-market companies don't arrive at Dynamics 365 as a green-field decision. By the time a PME or ETI (10-250 employees, roughly) starts evaluating consolidation, it's typically running 8 to 15 disconnected SaaS tools bolted together over five or six years: a lightweight CRM bought by sales, an invoicing tool picked by finance, a marketing automation platform sold in by an agency, a separate e-signature app, sometimes two. 

That history shapes how these companies approach consolidation and where they go wrong. After 40+ mid-market Dynamics 365 CRM/ERP implementations in the country, our team has noted four mistakes that show up often enough to be worth naming.

Mistake #1: Underestimating data ownership and French data residency questions

Retiring a SaaS vendor sounds simple until someone asks where the customer data lives, who the data controller of record is, and what the contract says about export format and retention after termination.

French organizations have drawn their own conclusions and write them into contracts. They expect:
