Invoice numbers are auto-prefixed with your business initials and financial year — e.g. BSC/26-27/. You only type the running serial number.
InvoicePro checks your invoice number against all previously saved invoices before generating. If the number is already used you get an error and generation is blocked until you use a unique number.
Add an E-Way Bill number directly on your invoice. The field appears in the invoice details section on both the on-screen preview and the downloaded PDF.
A real-time 5-step progress bar (Business → Client → Bank → Items → Ready) shows exactly which sections are complete and how close you are to generating your invoice — helpful on mobile where sections are collapsed.
Every form section collapses and expands individually. Section headers display a live status badge — green Done when all required fields are filled, red Fix errors when something needs attention — so you always know where to focus.
