Kimai
InvoicingTurn working time into clear records.
Kimai structures time records around customers, projects, and activities. Users record duration and context; administrators configure rates, teams, permissions, and budgets. Reports, exports, and invoice templates then turn the same records into material for operational review and billing.
- Track timers and timesheets by customer, project, activity, user, and tag
- Apply teams, roles, rates, and time or money budgets
- Create reports, exports, and invoices or integrate through a JSON API
What people use it for
Capture project time consistently
Let team members run timers or enter timesheets against an allowed customer, project, and activity structure, with tags and descriptions supplying the context needed for later review.
Prepare billable work for invoicing
Apply configured rates to selected time records, filter the relevant period and client, and create an invoice or export without re-entering the work log.
Review capacity and project performance
Use project budgets and reports to compare recorded effort with commercial limits and planning needs. Evaluate additional workforce features against the relevant plugins.
