A1.iO is an integrated, web-based Enterprise Resource Planning (ERP) software developed by Alliance Technologies that targets business software requirements of medium and large sized organizations.[1][dead link] A1.iO has its history in both Alliance Technologies' Ultima Applications as well as the Adempiere Open Source ERP.


A1.iO is primarily developed by Alliance Technologies with enhancements coming in from the channel partners as well as clients. Whilst open source, A1.iO is only available through the Channel Network of certified partners.

The first version of A1.iO 1.0 was based on enhanced Adempire ERP integrated with the Ultima Applications. A1.iO 2.0 however is a complete rewrite of the earlier edition with the Ultima applications already rewritten and integrated to form a single codebase that is based on a modern 3-tier architecture.

A1.iO is primarily developed in Java based on a 3-tier architecture of a GWT Ajax-based front-end, J2EE compliant application server, and the Postgres SQL Server as the database backend.

The User Interface is primarily built up at run-time using rules stored in the database by the application dictionary. This allows the user interface to be built up separately for different platforms such as computers, smartphones, and other handheld devices.
