What is Microsoft Dynamics-NAV?

From its origins in the 1980s, Microsoft Dynamics NAV, formerly Microsoft Business
Solutions-Navision, has grown from a relatively simple financial management system into a full-featured business management solution on which more than 50,000 small to midsize companies in more than 150 countries depend.

Microsoft Dynamics NAV 5.0 builds on years of incremental growth and technology innovation to deliver a superior business management solution that gives you the freedom to focus on your business—not on maintaining your business management software.
