Built for how you work

Stays out of your way while you code

You want to track time, not manage a time tracker. Clockbill keeps the daily part fast and does the billing math for you.

  • Keyboard first

    Press N for a new timer, P to pause, S to stop, and ⌘K / Ctrl K for the command palette. Press ? to see every shortcut.

  • Fast manual entries

    Forgot to start the timer during that debugging session? Type 1:30, 1h 30m, 90m or 1.5 and you are done.

  • One timer, every device

    Start on your workstation, stop from your phone. Changes sync live across devices and browser tabs.

  • A rate per client

    Agency work at one rate, direct clients at another, a retainer in a different currency. Each project has its own rate.

  • Billable or internal

    Mark code review, estimates or onboarding as non-billable. It stays in your reports but not on the invoice.

  • CSV when you need it

    Export entries as CSV for a client timesheet, your accountant or your own scripts.

Month end

From commits to invoice without the spreadsheet

Everything you need to bill a contract is already in your tracked hours.

  • Reports by client, project and date range
  • Billable totals per currency
  • Billing time rounding, such as to 15 minutes
  • Weekly timesheet view for client reporting
  • Printable invoices with automatic numbering
  • Tax rate, due date and notes on invoices

Questions from developers

Is there a CLI, an API or an IDE plugin?

Not today. Clockbill is a web app you can install to your desktop, and it is built to be quick from the keyboard. You can export your entries as CSV at any time.

Can I track time for several clients at different rates?

Yes. Group projects under clients and give each project its own hourly rate and currency. Reports and invoices use the right rate automatically.

Can my client see my hours?

Only what you send them. Clockbill has no client logins; you send a CSV export or an invoice PDF.

Is it really free?

Yes. Every feature is free, with no trial and no credit card. There are no ads, and your data is never sold.

Bill every hour you code

Set up your clients in a minute and have your invoice ready at the end of the month.
