How to create a final invoice that automatically deduces the invoices for advance payment

Local Booking Manager is a powerful and flexible invoicing tool which allows you to issue invoices for advance payments, storno invoices and final invoices for the complete service from one place.

Traditionaly, invoices for advance payment were created at a moment when a partial payment for the service has been received and were canceled in a separate documents once the service started and final invoice has been creates for the client. This resulted in three new documents: one final invoice and at least two storno invoices that needed to be forwarded to the bookkeeping.

To reduce the number of documents that are generated, Booking Manager from the version 10.0 allows you to create a final invoice where innitial advance payment invoices are automatically deduced, so there is no need for separate storno invoices as before.
 

How can I set-up the new kind of invoice?

The first step is to activate new kind of invoice in the Preferences / Reservation Settings / Payments (1)
After this step all new final invoices will automatically deduct all advance invoices on the calculation.


For a typical reservation with two advance invoices and one final invoice the final invoice will look like the picture below. The new elements of the invoice are VAT correction items according to payments already made (1), and a VAT difference and total that remains to be charged to the client (2)
