Bar Cop has six categories that you can track products in: liquor, wine, bottle beer, draft beer, food, and miscellaneous. When you click on a section link in the main menu, you will land on that section's product category selection screen.
Select the product category that you want to go to in that section. When you want to change product categories, simply click the main menu section link again and then click the new product category.
Things to know:
1) When you are finished working in one product category, click the main section link to return to the product category screen for that section, and select another category.
2) Under "Inventory Reports", both the analytical metrics and variance analysis sections have an additional category choice for establishment totals.
