# Add/Edit Contract Rate Items

The *Contract Rates* tab on the ticket screen allows you to enter and edit any rate items covered on your contract. These items can include products and services charged to the customer on a one-time basis (billed to the customer only once). **NOTE**: Once a contract is active, you will be unable to make any changes. Instead, you'll need to cancel the contract and create a new one.
