Once a product has been put into production, you can prepare it for billing. To do this, a product must always be "recalculated". You do this in the Accounting > Invoicing.

In invoicing, you can see the planned and actual time for each operation. You can also finally adjust the delivered circulation and decide whether you want to invoice the product at the planned unit price or at a fixed price that you have adjusted manually.
​

As soon as the final cost estimate is complete, you can bill the invoice.  
​

As soon as a product has been recalculated, it is ready for billing under Accounting > Invoices. Click on "Invoice Fully" to automatically create an invoice for this product. This invoice can invoiced with one click and sent to the customer by e-mail or post.
