Create the Advance Invoice to collect a deposit on the booking.
To issue the advance invoice for a single booking, open the booking you wish to invoice and click on the Advance invoice menu item.
To issue a new advance invoice for multiple booking, open the bookings list and select the lines you want to include in the advance invoice.
Then open the menu and click on Advance Invoice.
For each booking selected an invoice line will be generated with the unit price equal to the price set on the individual bookings.
Change the line to invoice part of the amount.
If you need help consult the guide on how to create a customer invoice.
Complete missing data and save.
Keep in mind that you can only create one advance invoice for each booking.
Advance invoices are shown, like invoices, in the invoice list.
You can also open an advance invoice from the Booking, in the tab Other, by clicking on the blue arrow in the field where the number is shown.
Remember that when you issue an invoice for a booking that already has an advance invoice, the system will add a line, to the invoice lines, with a negative amount equal to that of the advance invoice.
