Calendar Timesheet

Google Sheets add-on for freelancers

Your calendar already knows your billable hours.

Turn Google Calendar events into a timesheet and a per-client bill in one click. No timers to forget, no new app to learn.

  • Free up to 30 events
  • Read-only calendar access
  • No credit card
30-second demo: calendar events become timesheet rows, one rule sets each client's rate, and the per-client totals add up to the bill.

Timers leak billable time. You forget to press start, or to press stop. Your calendar has the real record, so let it do the work.

Everything you need to bill by the hour

Match events to clients

One line per client: acme => Acme Corp | 120. Or start an event title with [Client]. Every event lands under the right client at the right rate.

Bill the way you invoice

Round to 6, 15 or 30 minutes, up or to the nearest step. All-day events and meetings you declined are skipped automatically.

Two sheets, one click

A detailed Timesheet (date, time, client, hours, amount) and a Client Summary with total hours and amount per client, ready for your invoice.

Your data stays yours

Runs inside your own Google account with read-only calendar access. Events are never sent to or stored on our servers.

Questions

Do you store my calendar?

No. Events are read inside your own Google account while the report is generated and written only to your spreadsheet. They are never sent to our servers. See the privacy policy.

What does "events per report" mean?

Each time you generate a timesheet, the free version includes up to 30 matching calendar events. Pro has no limit.
