The main purpose of mapping your POS Items is to establish a definitive link between POS sale items and WISK inventory products.

This is essential when it comes to identifying variances. Your variance compares a product's consumption to a product's sales.


Consumption is purely the difference in stock counts from one inventory to the next while taking invoices, returns, and depletions into consideration. It does not consider sales at all.


For products that find themselves in multiple POS Items—sold by the shot, single, full unit, or in several cocktails—it becomes necessary to have this POS Item Mapping in place in order to link each POS Item's PLU with the associated WISK product.

Let us take the following Belvedere sales for example:

Belvedere Shot (1 oz) x 10

Belvedere Single (1.5 oz) x 5

Vodka Cocktail A (2 oz) x 6

Vodka Cocktail B (0.5 oz) x 2

If all these items contain Belvedere, then properly mapping these POS Items will tell us that you sold a total of 30.5 oz of this product. We can then compare this value to the actual consumption to see if there had been any overpouring or theft.

If any items are not properly mapped, we would be comparing the consumption to wrong sales total and so that variance would not be reliable.
