Frequently asked questions
Still wondering? Let’s clear it up.
Visit the help centreWho is Klausi for?
For the self-employed and small teams who bill their time — freelancers, creatives, consultants, agencies. If your hours should turn into invoices, you’re in the right place.
What’s free — and what costs extra?
The core is free forever: timer, weekly calendar, and reports. Pro features like the automatic invoice draft and PDF export are part of the paid building blocks. Details on the pricing page.
Can I switch from Toggl, Clockify & co. — do my old entries come along?
Yes. You can import your existing entries via CSV — Klausi detects the columns automatically and creates projects and clients along the way. There’s no lock-in: you can export again anytime.
How fast am I up and running?
In under a minute. Create an account, start the timer — attach project and client with one click. No setup, no onboarding marathon.
How do tracked hours become an invoice?
Every session knows its project, service, and rate. From that, Klausi builds an invoice draft with finished line items in the finance area — you review it and export it as a PDF, instead of piecing everything together by hand at month end.
What if I forget to start the timer?
No problem. You can create or correct any entry manually at any time. The timer is the shortcut, not a requirement — your time tracking stays complete without it.
What happens to my data — and can I get out again?
Your data is stored GDPR-compliant on EU servers. No lock-in: you can export your time and invoices anytime. What you capture in Klausi is yours.
