### **Manage Cost Lines**

The Cost Lines section allows you to update the materials, labor, services, and other costs included in the PO or SC.

You can edit, add, duplicate, or delete cost lines as needed.

[![](https://help.buildern.com/hubfs/Knowledge%20Base%20Import/18aca4bd-5b71-4add-b3d9-bd9729c257cc.png)](https://downloads.intercomcdn.com/i/o/suco1tn6/2467463698/824418ee678274121bf3d741051d/18aca4bd-5b71-4add-b3d9-bd9729c257cc?expires=1792671300&signature=cdef75343327e41dcdabbf5bfdf95ad32e012c4f603c20c80b86d159b3a61349&req=diQhEc14nodWUfMW1HO4zWjvaQozLSqvNjntIQ10blMbRJmr2Iw%2FZS6OB2iT%0Ax1YP0vRjCDYd2EZrpXM%3D%0A)

You can also customize the displayed columns by clicking the **Manage Columns** icon in the upper-right corner of the table. This allows you to show, hide, and reorder columns based on the information you need to review or edit.

[![](https://help.buildern.com/hubfs/Knowledge%20Base%20Import/3d22f68e-f490-4a71-b4e8-42249598b9cd.png)](https://downloads.intercomcdn.com/i/o/suco1tn6/2467463707/401447d624a4c1b8981468bb756e/3d22f68e-f490-4a71-b4e8-42249598b9cd?expires=1792671300&signature=d628df4a996bd4b7ecfece1d7aae14d15c6907d5d26c22427437b2b5dbd01cbf&req=diQhEc14noZfXvMW1HO4zV1MH%2F7R%2BDvx9d1zT%2B07Fs6oEkFyVRKu4GPr57N7%0Ae%2B1AiRbU0qb%2Fkw3xKkI%3D%0A)

Additional actions are available from the **⋯ (three-dot menu)** next to each cost line. From there, you can duplicate an existing cost line or delete it if it is no longer needed.
