Hours slip. Invoices shouldn't.

The 30-second version, with sound.

How it works

From the first minute to a paid invoice.

Four steps, and the first one is a single click in your menu bar.

Track from the menu bar

Press play on a project. The timer survives quits, restarts and sleep.

Organize by client

Rates, currency and payment terms per client. Budgets per project.

Invoice the unbilled time

Pick a client and a period. Rounding, tax and numbering are done for you.

Export a clean PDF

Letter or A4, with your logo and your own templates. Add fixed fees, a discount or a PO number, preview every page, then email it.

Inside HourSlip

Everything between the timer and the invoice.

Edit it, preview it, send it

Add fixed fees or expenses, a discount and a PO number, and watch the PDF update as you type. Mark it sent, then paid. Overdue invoices flag themselves.

Always one click away

The menu bar panel shows what's running, today's total and your recent projects. On a MacBook with a notch, the timer sits right beside it.

FAQ

Questions, answered.

Where is my data stored?

In HourSlip's sandboxed container on your Mac, or in HourSlip's data folder on Windows and Linux. HourSlip never sends your data anywhere. It only goes online to check your Pro license key with polar.sh and to look for updates on this site. It keeps daily backups for 14 days, and Settings can export a full JSON backup.

Does it track what I do on my computer?

Only on your computer, and only a little. To ask about idle time and suggest projects, HourSlip notes when you're at the keyboard and which app is in front. It never records your screen, what you type or window titles. That log stays on your computer for 30 days, is never sent anywhere or included in backups, and Settings → Permissions turns it off or deletes it.

What if I forget to stop the timer?

After 10 hours HourSlip offers to stop it 1, 2, 4 or 8 hours after it started. If your Mac sleeps for more than 10 minutes, it asks whether to keep that time.

Can I bill in euros, pounds or another currency?

Yes. Each client has its own currency, rate, payment terms and default tax. One invoice uses one currency.

Can I bring my data from Toggl or another tracker?

Yes. Settings imports Toggl Track detailed reports and HourSlip's own CSV, and creates any clients and projects that are missing. The free version imports and restores one client; Pro has no limit.

Is Pro a subscription?

No. Pro is a single $29 purchase through polar.sh. It unlocks unlimited clients, invoices without the footer and CSV export. Paste the key from your purchase email into the upgrade sheet in HourSlip. One key works on one computer at a time, and you can move it from Settings.

Is the download safe to open?

Yes. On the Mac, the disk image and the app are signed with a Developer ID and notarized by Apple, so macOS opens them without warnings. The Windows and Linux builds are made automatically on GitHub's build servers from the same source; Windows shows a SmartScreen prompt the first time because the beta isn't signed with a paid Windows certificate. Updates are checked with their own signature either way.

Does it run on Windows or Linux?

Yes. HourSlip for Windows and Linux lives in the system tray, keeps the same clients, invoices, templates and PDF layout as the Mac app, and reads Mac backups, so you can move your data between computers. A Pro key works on any of them, one computer at a time.

What do I need to run it?

A Mac with macOS 14 Sonoma or later (Apple silicon or Intel), a 64-bit PC with Windows 10 or 11, or a 64-bit Linux desktop.

Your next invoice starts with a click.

Free while in beta. Nothing to sign up for.
