Serialized Inventory is a powerful tool that allows for accurate tracking of individual items or equipment in your inventory by assigning unique serial numbers. Unlike generic quantity tracking, Serialized Inventory ensures detailed monitoring and traceability for each specific item, enhancing accuracy and accountability in your inventory management. *** # Importing Your Serialized Inventory You can easily import your serialized inventory items into FieldPulse for use when creating Estimates and Invoices by utilizing our mass import tool. Click [the serialized inventory import guide](/using-fieldpulse/data-imports-exports/importing-serialized-inventory) to learn how! *** # Creating Serialized Inventory As a reminder, Serialized Inventory can only be applied to line items marked as *Product - Inventory*, **not** *Services* or *Products - Non Inventory*. To get started, create a new line item or edit an existing one. Be sure that the Item Type is ***Product - Inventory***. Click on Item Type… From here, then scroll down to *Inventory* and toggle on *Track by Serialized Inventory*. Next, you'll need to add hubs. You can use a single hub or multiple hubs based on your needs. Click on Add hub To enter the details for your serialized inventory, select the plus icon next to the name of the hub where the item is located. Click on highlight Now you will enter the pertinent details for the item. The serial number is required, but you can also add the date received, unit cost, reference number, or attach an asset template. After adding the details, press *Save New Serialized Inventory*.
