Once we have clicked on the Invoice button through the Check Order screen, we will see a screen like the one we can see below:

If we do not have any customer linked with the order, we can click on the Customer section and the Search for Customers screen will appear.

From this screen, if the customer of the invoice already exists we will select it and click on the Ok button, otherwise we will click on the New customer button and we will add the client through the Customer Management screen.

It must be taken into consideration that the customer data that will appear on the invoice will be the data that has been entered in the More data tab through the Customer Management screen.

We can also modify the description of the invoice, adding, deleting or modifying anything, directly from the Invoice detail section.

Once we have finished to draw up the invoice, we have some buttons on the right side that allow us to make different functions:

Save: It will save the invoice and it will be registered so that we can access to the invoice from the Customer's Invoices screen.

Print Invoice: It will print the invoice in a sheet of paper size and the invoice will also be registered on the Customer's Invoices screen.

Print (receipt): It will print the invoice though the receipt printer and the invoice will also be registered on the Customer's Invoices screen.

The Cancel button allows us to exit of the screen without making any changes.
