This document compares Microsoft Dynamics NAV and Dynamics AX. It summarizes that Dynamics NAV is geared toward small to mid-sized businesses, is easier to implement and maintain, and offers flexibility for decentralized global operations. Dynamics AX is designed for large enterprises, allows for greater visibility across global operations but is more complex to implement and maintain. Both can scale as a business grows, but AX better addresses the needs of very large, complex multi-national organizations.
