- No paywall for invoicing
- No paid multi-currency

Free Time Tracking + Free Invoicing. Finally.
Clockify's free tier tracks time. That's it. To bill clients, you pay. Chronum includes professional invoicing, multi-currency, and batch billing — all in the free tier.

How It Works

Track
Record sessions with a native desktop app — no browser tabs required.

Organize
Manage projects with custom currencies and hourly rates per task.
- 3.
Bill
Generate professional PDF invoices directly from tracked hours — free, not a paid add-on.
Why Freelancers Switch from Clockify
Free tracking is great. Free billing is better.
Clockify built its reputation on unlimited free time tracking. But when you need to actually get paid, the paywall appears. Invoicing, multi-currency, and advanced billing features require paid plans starting at $3.99–12.99/month per user.
Chronum takes a different approach. We believe the core workflow — track time, bill clients, get paid — should be free. Our batch invoicing, PDF generation, and multi-currency features are all included in the free tier.
What Sets Chronum Apart
| Feature | Chronum | Clockify |
|---|---|---|
| Multi-currency | Yes | Paid |
| Rate history | Yes | Paid |
| PDF invoicing | Yes | Paid |
| Batch invoicing | Yes | No |
Bill Globally Without Paying Extra
Clockify charges for multi-currency. Chronum includes it free. Set unique currencies per project and see your total earnings in your home currency with automatic exchange rates.

Change Rates Without Breaking Past Data
Update your hourly rate anytime. Completed sessions keep their original rates, new sessions use the updated one. Your historical rates stay accurate — no spreadsheet fixes needed.

End-of-Month Billing in Seconds
Select multiple projects, generate invoices for all of them at once. Our batch invoice generator turns monthly billing from hours of work into a single click.
