# Transaction categories

A transaction category is a grouping of related transaction types that can be used to manage interest rates. Use transaction categories to configure credit refinancing and overdue accrual types at the program level. A program transaction type associates a transaction type with a transaction category and can also be used to set the charge order. Use Control Center to add or edit transaction categories and to add a transaction type to a transaction category.
