Agree what a useful time entry contains
Record the relevant task or project, the date and a short explanation of the work. Decide when a timer is appropriate and how manual entries or corrections are reviewed. Distinguish billable and non-billable activity according to the agreement rather than treating every recorded hour as chargeable. Consistent descriptions help project managers investigate a variance without asking someone to reconstruct a week from memory.
Review time before it becomes a commercial record
A timesheet review should look for missing context, duplicate entries and work outside the agreed scope. Set a clear cut-off for review and a route for late corrections. Project reporting can then compare effort with the delivery plan, while finance sees approved information for billing. Explain how time records are used to staff and limit access appropriately; activity measurement should support work management rather than encourage misleading totals.
