What is project billing in TimeHunter?
Project billing is a TimeHunter addon that lets you track time split by clients, projects and task types — with automatic billable amount calculation. Every work session can be assigned to a specific client with its own hourly rate. The system continuously calculates hours × rate and shows the current billable amount.
For accounting firms, law firms and agencies this means the end of a multi-hundred-row spreadsheet where every month you manually verify how many hours Anna in operations spent on client A, B and C. The employee taps start, picks a client and task type (reports, audit, advisory) — everything else is automatic.
How it works step by step
Add your clients
Enter manually or import from CSV. Each client: name, tax ID, email, 3 hourly rates.
Employee picks client at start
Mobile app or web: client list → pick task type → start. Time runs.
Generate invoice PDF
End of month: billing dashboard → client → PDF with hours × rate. Invoice attachment ready.
