Microsoft Dynamics AX

Microsoft Dynamics AX was one of Microsoft's enterprise resource planning software products. It is part of the Microsoft Dynamics family. In 2018, its thick-client interface was removed and the web product was rebranded as Microsoft Dynamics 365 for Finance and Operations as a part of Microsoft's Dynamics 365 suite.

Microsoft Dynamics AX was originally developed as a collaboration between IBM and Danish Damgaard Data as IBM Axapta. Axapta was initially released in March 1998 in the Danish and U.S. markets. IBM returned all rights in the product to Damgaard Data shortly after the release of Version 1.5. Damgaard Data merged with Navision Software A/S in 2000 to form NavisionDamgaard, later named Navision A/S. Microsoft acquired the combined company in July 2002.
