How is overtime calculated when daily limits are enabled?

When your daily overtime threshold (e.g., 8 hours) is exceeded on any active work day, the excess hours are automatically classified as overtime and multiplied by your overtime multiplier (typically 1.5x for time-and-a-half).

Can I print or sign the generated timesheet?

Yes! Click 'Download Approval PDF' to generate a commercial-grade vector PDF. It includes contractor details, client metadata, an itemized daily shift log, gross summary totals, and formal certification sign-off blocks for both the worker and client manager.

How does the 'Create Invoice' bridge work?

Clicking 'Create Invoice' bundles your logged regular hours, overtime hours, hourly rate, and client details into a cryptographically encoded payload that immediately opens the Invoice Studio with line items pre-populated and ready to bill.

Does the calculator support overnight or graveyard shifts?

Yes. If your end time is chronologically earlier than your start time (such as 22:00 to 06:00), the calculation engine detects a midnight rollover and correctly computes net hours without negative numbers.

Are my timesheet records and rates stored on a server?

Never. All calculations, CSV exports, PDF generations, and invoice bridges run 100% locally in your browser. Your financial rates, client names, and working hours remain entirely private.
