Live cost control: closing the loop between estimate and actual

A Tier-2 main contractor came to us with a familiar problem: estimates were sound, but by the time actuals landed in the QS's spreadsheet the project was already three weeks committed.

We built them a thin layer that lifted committed cost out of their procurement system in real time and paired it against the live BoQ. No big-bang ERP replacement, just a pipe and a screen.
