Microsoft Dynamics AX is a multi-language, multi-currency, industry-specific global Enterprise Resource Planning (ERP) software product.

The system supports operational and administrative processes for organizations in manufacturing, retail, service industries and the public sector.

Among its capabilities are financial management, HR management, manufacturing, supply chain management (SCM), project management and accounting, retail and business intelligence (BI) reporting.

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 name Navision A/S. Microsoft acquired the combined company in July 2002.

In September 2011, Microsoft released version AX 2012 and was made available and supported in more than 30 countries and 25 languages. The newest version was released in February 2016.

However, this version lasted only a few months as Dynamics AX was rebranded Microsoft Dynamics 365 for Operations in October 2016.
