Dynamics NAV
Microsoft's on-premise ERP for small and mid-sized businesses, the predecessor to Business Central.
Dynamics NAV (originally Navision) was Microsoft's on-premise ERP product for small and mid-sized businesses. It was acquired by Microsoft in 2002 and went through annual releases up to NAV 2018 before being rebranded and re-engineered as Dynamics 365 Business Central. NAV introduced the C/AL programming language and the role-tailored client, and it built a large global partner ecosystem around vertical add-ons. Mainstream support for NAV ended for older versions but many organisations still run NAV 2016, 2017, or 2018 and migrate to Business Central as upgrade projects.
