The screen below shows a list view of the invoice maintenance.
Click on the switch view icon and you will get the form for entering an invoice. You will notice at the top we have got the Billing Entities so by clicking on the down arrow we can select the billing entity and on the right hand side we have got the Number Range. The principal of this is that the invoice entry works in the same way as the project invoicing works. The only difference here is that you have a choice as to whether you want to do a direct invoice against the client (does not reduce work in progress) or you want to do it against the project. To get an idea of how the invoicing works please refer to the section on Project Invoice
