Things to know
If you only have the Purchasing module enabled, the Inventory section in the navigation bar is renamed Purchasing.
If you change the vendor in the Order Details section of the PO, remove the item added from the first vendor catalog to avoid errors.
Associate an unlinked item to a vendor's catalog
During PO creation, ServiceTitan lets you associate items to vendor catalogs that are linked to Full Procurement suppliers, even if the catalogs weren't added in Settings
> Purchasing > Vendors in advance. See Add vendor catalogs to vendor settings for more information.
Go to the navigation bar and click Inventory or Purchasing.
In the side menu, click Purchase Orders.
