About Us
Keystone Construction Software Pty Ltd was established in 2016 to broaden the reach of the existing ‘Client Manager’ software developed by one of the founding directors since 2001. The original package called the ‘Variation Writer’ morphed into ‘Costing Manager’ when quotes/tenders was introduced around 2005. Another package called the ‘Addenda Writer’ was introduced around the same time. The ‘Costing Manager’ went through another name change around 2010 and forms the basis of today’s package known as the ‘Client Manager’.
