Hello Cardpeople,

I'm pleased that you're exploring the latest features of QuickBooks Enterprise 2024. We use Categories in this platform to classify and group products and services. This feature makes it convenient for you to track and report on your business activities. You can set a hierarchy with up to four levels of subcategories to rank your categories.

Moreover, we use Items and sub-items to track and sell inventory, while categories are for classification and grouping products and services. 

Additionally, Item groups are used to organize and group similar items for reporting and analysis purposes.

To better manage and filter your reports by categories, I recommend reading the article: Use Item Categories in QuickBooks Desktop Enterprise.

Feel free to let me know if you have any further questions about categories. I'll be right here to answer them.
