We have an issue of security where users can create a product invoice, print it and then edit it changing the customer / product details.  This in effect creates a 'ghost invoice' without the stock figures being affected (we don't use SOP). As we deal in cash for many sales this means a product could be quoted to a customer at one price on the 'ghost invoice',  £200 for example but then the second invoice updated on the system shows £150 - the difference in cash being pocketed by the staff member. It is not obvious though because the stock matches and the invoice matches the cash receipted in to the business.

I seem to remember old versions of Sage used to give the print and update feature when you saved the invoice - this no longer seems to be available - is there any way and invoice can be set to automatically update to the ledgers when it is saved or printed?

Alternatively does anyone have any other alternative to helping prevent this issue?
