Tallybird — Calendar to Timesheet & Invoice

Turn your Google Calendar into billable-hours timesheets and invoices. Private: your data never leaves your browser.

Your calendar already knows your billable hours. Tallybird turns it into timesheets and invoices without handing your client list to another SaaS. Most calendar time-tracking tools want a monthly subscription, an account, and a copy of your data on their servers. Tallybird is the other kind of tool: one small yearly price, no account, and your data never leaves your browser, because there is no server to send it to. Made for anyone who bills by the hour and lives in their calendar. HOW IT WORKS 1. Paste your calendar's private iCal link (60 seconds; Google Calendar and Outlook) 2. Add clients with match keywords and hourly rates, and events auto-match by title 3. Generate a timesheet for any period and turn it into an invoice WHAT YOU GET - Billable-hours report grouped by client, with totals - One-click CSV export for Excel, Google Sheets, or your accounting tool - Smart rounding: round each event up to 6, 15, 30, or 60 minutes - Ignore rules for personal events, lunches, gym sessions - Recurring events, moved events, and cancellations handled correctly - Sample-data mode so you can try everything before connecting anything PRO (one small yearly price, not another monthly bill) - Unlimited history: bill any period, not just recent months - Invoicing with your logo, colors, and numbering, plus a tax line - Multiple calendars merged into one report (work, personal, per-client) - Try Pro free for 7 days — no card required PRIVATE BY DESIGN No account, no server, no analytics. Your calendar is fetched directly from Google or Outlook to your browser and processed entirely on your device. Read the privacy policy — it's one short page. STOP RECONSTRUCTING YOUR WEEK FROM MEMORY If you've ever sat down on invoice day trying to remember what you did three Tuesdays ago: your calendar remembers. Tallybird does the math.
