Quick Answer
Dynamics 365 is Microsoft’s broader suite of cloud-based business applications, while Dynamics 365 Business Central is the ERP application within that suite designed primarily for small and mid-sized businesses. For larger organizations with complex financial, supply chain, manufacturing, and global operations, Dynamics 365 Finance and Dynamics 365 Supply Chain Management are generally the better fit. Dynamics NAV and Dynamics AX are legacy products that evolved into Business Central and the modern Finance and Supply Chain applications, respectively.
