Dispense Control
According to international researches, there are up to 20% variances in a standard bar set up with manual stock-take.
Unfortunately, stock-control system software wouldn't help since it only helps capturing your losses.
The best solution would be an electronic bar control system which integrates to the POS.The exact portioning prevents over-pouring and spillage. All items have to be ordered with the Point of Sale before to release the portion. Alternatively, the item could be poured by the bar man/ woman and will be transferred to his/ her account in the POS for cashing up.
