Can someone explain the difference between Items and Class in QB. I think I am way over thinking this. Would you sometimes have a CLASS and an ITEM with the same name?

For example, CLASSes are used to track different segments of a business. QB gives an example of a contractor having classes such as kitchens, baths, decks. Then later on the lesson it explains items and tells you how to set them up and the example is for a contractor with
items for kitchen and decks.

Would these entries sometimes serve the same purpose or no?

Thanks a bunch!
