allocPSA started off as an in-house staff and resource allocation tool within the ICT services firm Cyber IT Solutions Pty. Ltd. (formerly Cybersource Pty. Ltd.) It went into production use in 2000, taking on the roles of project management and client relationship management, and grew organically as requirements expanded.
In early, 2006, Cyber IT Solutions decided to release the entire codebase under a Free and Open Source software licence. The code was hosted off SourceForge.net, where it remains, and has seen approximately 10,000 downloads.
A major new version of allocPSA is released every year. The most recent release happened on the 2nd of November, 2010. This release was version 1.7, and is available for download here.
