Company History

Concurrent Software, developers of SEQOS, was established in 1987 in Sydney, Australia.

All employees have logistics solutions backgrounds and appropriate university qualifications.

Using the team’s previous logistics experience and leveraging on highly innovative ideas from several custom-written implementations, the first packaged version of SEQOS was developed and installed in 1993.
