If you have a lot of items with serial numbers already in inventory, you may choose to not enter them all in QuickBooks right away. It’s OK to continue your current method of tracking while slowly moving to QuickBooks by entering all newly purchased or assembled items with serial numbers as you acquire them. Eventually, your company file will have all your serial numbers.
To assign serial/lot numbers to existing inventory:
