Products categories offer you an additional possibility to group products as you like to:
* produce reports broken down by Categories (Sales by products report)
* set up discounts for certain Products categories.

It is not mandatory to keep Categories.

To create a list of products categories, go to the Administration panel: Products\Products categories. A categorie value is set in the Administration panel: Products\Products and Dishes\Categories\Product categories field.

Unlike products group, the reference book of products categories doesn’t have a hierarchical structure so all categories are of equal value.

Example of using Products categories:
1) Category Products and Dishes set for breakfast:
* Eggs
* Milk
* Bread
* Tea

2) Category  Light First course:
* Borscht
* Meatball Soup
* Chicken broth
