Most projects don't become unprofitable because of bad pricing. They become unprofitable through slow margin erosion - the cumulative effect of scope additions that don't get billed, hours that get absorbed rather than charged, and inefficiencies that compound over a long engagement.
The mechanism is almost always the same: the project is profitable at the point of sale, and it remains profitable on paper for most of its duration. But the actual hours being logged consistently exceed the planned hours - and because no one is tracking the discrepancy in real time, no corrective action is taken. By the time the project closes, the margin has been consumed.
This is why accurate billable hours tracking is foundational to project profitability. If hours aren't being logged accurately and in real time, you can't compute profitability accurately. The two are inseparable.
But accurate time logging alone isn't enough. You also need a financial model that translates hours into costs, compares costs to revenue, and projects where the project will end up - before it ends. That's what the four metrics below are designed to deliver.
