What method?
Adding items would required larger payment than total on print… Customer would not accept this.
If you mean adding order but only taking payment for printed total what are they steeling? Product?
After he Printed the Bill he was adding new products so that he gets 2 tickets for clients and the other ticket was used for him to steal, he printed 2 tickets and hit settle only once the products from the other tickets was sold without using the software so that the stock will remain higher, sometimes he was buying drinks from outside and sell it in my bar
Also i am using a rule that lock the Settle button if the ticket is unlocked, if you print bill the settle will become active but if you add by mistake a product the ticket will get new status and the ticket will be unlocked and user can’t settle without printing the bill one more time this is another reason i need the button locked after bill was printed
You can do that but it wont fix him stealing. He will just find another way. You should take care of him first. A better method is to use ticket logging and log all activity. Also if he only settled for part of the ticket then the actual ticket will still show unpaid.
