Short answer: track every hour against a project, keep proof for each day, review weekly, and invoice from the tracked totals, not from memory.
Track against a project from the start
Hours with no project are hours you cannot bill. Pick the project before the timer starts, and keep project names the same as on the client's side.
Keep proof
Screenshots and activity levels settle questions in minutes. Tell contractors up front what is recorded and when. It is easier to agree on proof before a dispute than during one.
Review weekly, not monthly
A weekly look catches missing time while people still remember it, and means no surprises at invoice time.
Invoice from totals
Export hours per project and attach the summary. Clients trust numbers they can inspect.
Common leaks
- Short calls and chats that never get logged.
- Switching projects without switching timers.
- Rounding down "to be nice" every day.
Weekly routine
- Friday: check each project's hours against the plan.
- Approve missing time.
- Flag projects over budget before the client does.
TrustHours gives timesheets by person, day and project.
