SAP Stack Alignment
Existing SAP ERP makes SAP CRM (or successor SAP Sales Cloud) a default. Integration is deep, if not always simple.
Dynamics 365 vs SAP
D365 wins on Microsoft 365 integration and generally modern UX. SAP wins on tight backend coupling with SAP ERP.
Cost
Neither is cheap. Partner implementation cost is a significant percentage of TCO.
Industry Fit
D365 broadly general. SAP stronger in manufacturing, logistics, and industries where SAP ERP already dominates.
Modernization Bets
Microsoft is investing heavily in Copilot across modules. SAP is embedding AI via Joule. Both roadmaps credible.
