A wall rack is a wall-mounted liquor system with an electronic counter that records your sales.
The liquor system acts as a counting device, recording the number of pours and drinks sold from up to 255 wall-mounted bottles. The wall rack's liquor bottle counting unit also registers every time a bottle is changed, ensuring that you can record the number of drinks sold and how many liquor bottles have been used.
These registrations mean that you can easily keep track of your consumption and earnings. The registrations show you, among other things, your turnover per bottle and create a log of the changes in price level. It gives you a good overview behind the bar.
