Once an invoice has been created and closed in the Job Book, the user may not edit the invoice, unless they have access to the Accounts Book.
The invoice is editable from the Accounts Book until it has been marked as posted. When you have entered the Invoice in your own accounts package, you will need to mark the Invoice or Purchase Order as Posted to show that the Invoice or Purchase Order has been processed.
Invoices which appear with a yellow background are master invoices which are linked to scheduled invoices, when they are created. Invoices, which appear with a salmon or pink background indicate the job status is less than confirmed.
To mark an invoice as posted, simply check the posted box in the posted column. Printed is checked when an invoice is printed, but only from the invoice form.
