How does the software know what items to track? Will it track serial numbers?
The software uses the orders you receive and the inventory system to define which items are to be tracked for the purposes of warranty. As a result, when your company sells the item through an invoice, the serial number (if being used) and the details of the transaction are saved to a contract master item for storage. If there is a warranty claim, your company can look up the serial number and see when it was purchased and the applicable warranty information.
