How to track time in 3 steps

  1. Enter the client and your rate. Set who you're working for and what you charge per hour.
  2. Hit start and work. The timer runs in your browser — close the tab and it keeps counting from the saved start time.
  3. Send hours to an invoice. One click turns every logged entry into invoice line items (hours × rate), ready as a PDF.

Why track time even if you bill per project

Tracked hours reveal which clients and project types are actually profitable. BillsZilla's tracker is free forever with no signup — start/stop timer, entry log, and one-click export to the invoice generator. Your data never leaves your browser.
