The difference that matters

Kimai provides more deployment control. You can run the open-source application yourself or pay Kimai to operate its cloud version. That flexibility is valuable when source access, self-hosting, built-in invoicing, or customization matters.

Time & Bill removes that infrastructure choice and offers a smaller managed product. Its fixed Startup and Office prices become more economical as a team fills the included seats.

Time & Bill may suit you better if

  • you want a managed browser and mobile product without operating servers;
  • fixed pricing for up to 5 or 20 users is more useful than per-seat pricing;
  • you need project reports, exports, expenses, mileage, budgets, and clear project roles;
  • you prefer a focused workflow over an extensible platform.

Kimai may suit you better if

  • open source or self-hosting is a requirement;
  • built-in invoicing, plugins, custom fields, working-time accounts, holidays, or kiosk mode matter;
  • you accept responsibility for self-hosted maintenance, or prefer Kimai Cloud’s per-user service.
