In order to create an invoice, choose 'Direct Invoice' in 'Sales':

The invoice will be created by clicking 'Place Invoice'. Due to the fact that some information must be updated internally, it may happen that the button 'Place Invoice' must be clicked twice.
The invoice is created and already booked too. It can be printed by pressing 'Print Sales Invoice' as a PDF. The result should look something like this:
Please note that booked invoices cannot be deleted. Especially at the beginning this can happen, though. We recommend that you initially experiment with a sample tenant before the definite version is active. A new company can be created as described in 28.2.
