Why assign a category to a transaction
How to set up your categories
If there are no categories yet, choose "Use suggested set" or "Start blank". For a category of your own, click "New category" and enter the "Name". Choose the "Group" or leave "No group". Choose the icon and color next to the name. For a new group, click "Add group" and name it. Save. The name should say plainly which spending or income the category covers.
