Flag unexpected overtime in Gusto before it inflates your payroll cost

Every morning in payroll week, WebRun opens Gusto, reads overtime hours logged in the current pay period for every hourly employee, compares each total to the employee's average overtime over the prior three pay periods, flags anyone with overtime more than 50 percent above their normal pattern, and posts a review list to Slack while logging the anomalies to Google Sheets.

In short

How do I automatically flag unusual overtime hours in Gusto before payroll runs?

Every morning, WebRun opens Gusto and compares each hourly employee's current-period overtime to their three-period baseline. Anyone with overtime more than 50 percent above their normal pattern is flagged in a Slack alert with hours and estimated cost impact, while Google Sheets logs the trend so managers can catch both one-off spikes and recurring patterns before paychecks go out.

  • Unusual overtime caught before paychecks go out, not after the payroll cost surprises finance
  • Managers get a focused anomaly list rather than reviewing every timesheet manually
  • Rolling Google Sheets trend reveals departments with chronic overtime patterns for planning

Questions, answered

Will it reject or reduce overtime hours in Gusto automatically?

No. WebRun flags anomalies for human review but does not alter time records. Managers verify the hours and make any corrections in Gusto directly before the payroll run closes.

What overtime threshold triggers a flag?

By default, any employee whose overtime in the current period is more than 50 percent above their three-period average is flagged. You can adjust the threshold and comparison window when setting up the workflow.

Does it catch all overtime types, including California double-time?

WebRun reads overtime as recorded in Gusto, which applies federal and state overtime rules including California daily overtime and double-time. The flag is based on hours, so any overtime type counts toward the anomaly check.
