Your accounting system pulls job cost together at month-end, but by the time the final numbers are in, the project finished weeks ago. Labor that ran long, materials over estimate, scope that expanded without a matching adjustment. The full picture arrives after the window to act on it has closed.

The people closest to the work usually know when costs are drifting. A foreman sees the crew running long, a project manager hears the client add scope in a meeting. But the accounting system doesn't see any of that until the invoices, timesheets, and POs land days or weeks later. By the time everything reconciles, the overrun is history.

A 15% labor overrun caught in week two is a conversation about scope, staffing, or a change order. The same overrun caught at close is a loss. Whether it's reallocating crew on a job site, adjusting billing on a consulting engagement, or renegotiating an MSP contract, the math is the same. Every week the signal arrives late costs money you can't recover.
