A late client approval can push worked hours into the next invoice cycle. The risk grows when the team chases approvals through email and spreadsheets.
Keep one clear missing-approval list
Show the client, location, worker, shift date, hours, and invoice deadline. This gives the operations team the exact approval to chase.
Check again before the invoice closes
When approval arrives, match it back to the timesheet and invoice line. Do not rely on the approval email alone. The hours and location still need to agree.
