To generate a preview for any account as it currently stands, simply click the Preview link in the reservation page in the top right hand section.
This can be printed and given to a guest as a current account statement if required.
Generating a full invoice is very similar to the preview. This time you will select the Generate invoice link instead. A billing document will be generated for accounting purposes. This document will be in the predefined format you have configured for your sales invoices.
A new window window will be displayed (See image below) where you will given some printing options. You can generate a complete invoice, only for accommodation or only for other charges, apart from accommodation. You can choose if it will show the amount paid, or still pending and what sales channel the original booking was generated from.
The invoice document will then be ready to print as per your custom configurations
