Instead of asking, "Mark as printed" after an invoice prints, to just automatically mark it as printed?
 
I know this would lead to more voided invoices but we are having some problems with our dispatcher not marking it as printed, sending out the invoice, releasing something else which then clobbers the previous invoice.
 
Plus, this is a potential theft/fraud issue.  We are now putting a number on our pre-printed forms, but for people using plain paper, I think this could be a real problem.
 
I would rather have some voided invoices then try to explain to a customer why 2 different invoices have the same invoice number.

You can already change the default setting using the questions on the SO-F screen and the Save Settings button.

Lynn's advice benefited our company. THANKS SO MUCH! It's worth the price of that cup of coffee.
 
Our Sales gals were delighted when I informed them how to change the default setting.

Just some further thoughts.
 
We deliver our products and sometimes our driver's collect cash.  Also, sometimes customers come to our office and pay cash.
 
A dishonest employee could release 10 widgets and print an invoice that totaled $1000 or $100 per widget and NOT mark it as printed.  
 
They then could change the invoice to 1 widget, mark it as printed and pocket the $900.00
 
An employee could also just make a mistake.  Most of our orders are multiple deliveries on the same sales order.  If the dispatcher THINKS they marked it as printed and did not, released other items, then that original invoice is lost in the system, although not on paper.
 
We would not know there was a problem until we saw inventory descrepencies and even then, we would not know HOW the inventory disappeared.
 
It seems that it would be a fairly easy program change, just add an option in the header files.
 
I might be willing to pay if not too expensive.

wildco, I agree, the automated "marked as printed" needs to be a header option.
 
We caught a problem the other day that had we missed it, would have resulted in a $7500 loss.
