Why Is the Invoice Tab Not Showing on the Booking Page?

The invoice tab only appears after the booking has been converted to an invoice. If the tab is not visible, it means the booking has not yet been converted to an invoice.

To create the invoice and display the tab, press the Convert to Invoice button in the action bar at the top of the booking page, or create the next booking directly by pressing Pay from the calendar window.

After conversion, the tab appears with the invoice number and status — example: Invoice #00012 (Unpaid).
