How It Works

  1. 1.

    Set

    Define your base hourly rate for a project or set unique rates for specific tasks.

  2. 2.

    Update

    When your value goes up, just update the rate for the project or task. Chronum won't overwrite your historical data.

  3. 3.

    Bill

    Generate invoices where past sessions maintain their original value, and new work uses your updated pricing — automatically.

Raise Your Rates Anytime, Keep Historical Rates Intact

In most basic time trackers, the hourly rate is just a static field. If you raise your rate mid-month and change that number, the software often applies the new price to all your work — even the sessions from three weeks ago. You're then forced to manually edit every single log to fix the math.

Chronum treats your financial history with respect. Once a session is tracked at a certain rate, that historical rate is preserved. You can evolve your pricing for projects and tasks as often as you need without fear of breaking your end-of-month invoicing. It's clean, professional, and built for freelancers who are consistently moving up.
