Quantify enables you to add and track individual product serial numbers. However, before you can add products with serial numbers to the Product Catalog, you must enable serialized asset tracking in the Global Options dialog. Once enabled, Quantify makes it easy to add products with serial numbers. However, remember that products cannot be both serialized and un-serialized. If a product was previously used as an un-serialized product, you cannot modify it to be serialized. Once you have added the serialized items to your Product Catalog, you can add them to Branch Office inventory via Transactions, or you can add them to Branch Office inventory using Adjust Quantities. Finally, if you want to add serialized inventory that will be re-rented from a third party, you must create a re-rent transaction.
