FAQ

What is project‑based invoicing?
Linking all financial docs and work records to a project so you can invoice by milestone, time, or deliverable—and see budget vs actual and profit in real time.

How do I keep an eye on project costs?
Link invoices and bills to the project and review their totals in the project’s financial tab; export data for deeper analysis when needed.

Can I attach subcontractor bills to a project?
Yes—create bills inside the project or link existing ones. They reduce profit and show in cost reports.

Can I migrate existing documents into a project?
Open the project → Link Documents → select quotes, invoices and bills. Tags update instantly.

What about multi‑currency projects?
Invoices appear in client currency; filter reports by currency and reference the documented exchange rate when comparing performance.

How do I close or archive a finished project?
Switch status to Completed. It drops from active views but remains searchable and exportable.
