Timesheets have a reputation as the chore everyone puts off. Part of the reason is that they often lead nowhere: hours go in, and nothing visibly changes. The fix is to make logged time do real work.
A simple weekly grid
Weekly time entry is a grid limited to the projects and work a person is actually staffed on. Nobody faces a blank week wondering what to type, and there is less to get wrong.
Approvals that lock the week
Time approvers can correct or log hours directly. A submitted week is locked against changes until it has been reviewed, so the numbers that reach reporting are the numbers that were approved.
From hours to cost
Each person has an internal cost rate. Logged hours multiply through that rate to become real project cost, and that cost feeds straight into the project's Budget Health. A job that is quietly running over shows up as a number, not a surprise at the end.
The whole chain
A deal is won, the project is staffed, time is logged, cost rolls up, and it all shows in reporting. Because every step is on the same data, you can follow a sale all the way to what it cost to deliver.
Why it is worth the discipline
If you have ever finished a project and honestly could not say whether it was profitable, time that is connected to cost is the cure. It takes a few minutes a week and replaces a lot of guessing.
