What is the difference between Microsoft dynamics AX and NAV?

Dynamics AXDynamics AX (AX) is Microsoft’s enterprise ERP and MRP solution. AX is a favorite amongst mid-sized to enterprise companies especially within the manufacturing, distribution, supply chain & retail industries. It offers great support for companies with complex needs such as: multi-country, multi-language, multi-site, multi-currency, etc.

Dynamics NAVDynamics NAV (NAV) fits well within the small to mid-sized market (i.e. companies with annual revenues between10 million –500 million) but some small enterprise companies use it as well. In comparison to Dynamics GP, NAV offers more flexibility when it comes to out-of-the-box (meaning not needing to customize the system) set-up and configuration. NAV fits the needs of companies in North America, South America, Europe, Asia, Etc. Like Dynamics AX, it also offers flexibility to accommodate the needs of larger organizations that are doing business in multiple countries.NAV has a very friendly user interface and it allows users to easily modify the user interface, the report formats, forms, etc.
