Why export timesheets from one tool, manage Kanban tasks in a second, and copy billable hours into a third just to send a client invoice when TimeTracker handles the entire agency workflow in one self-hosted platform? Start a persistent server-side timer from any browser or log hours manually using saved templates, bulk entry forms, and automatic idle detection. Project managers organize deliverables across drag-and-drop Kanban boards, Gantt timelines, and threaded task comments while monitoring real-time project budgets and cost burn rates. A built-in CRM tracks client contacts, lead scores, and sales pipeline stages before work even begins. When billing day arrives, you convert unbilled hours, reimbursable receipts, mileage logs, and per diem allowances directly into branded multi-currency invoices without double-billing a single minute. Finance teams can customize PDF invoice layouts, automate recurring billing schedules, and transmit EN 16931 compliant electronic invoices via Peppol or embedded ZUGFeRD/Factur-X XML. Interactive analytics dashboards and scheduled CSV or Excel exports give every stakeholder complete visibility into billable utilization.
