Serial Numbers
In inventory maintenance on each item you want to track serial numbers for, check the track serial numbers box under the optional tab. (Remember to update each item you change!)
Once that's set, anytime you sell or take in trade an item where serial numbers are supposed to be tracked you will be prompted for the serial number. You may then type it in, or scan it if the serial number is barcoded, and the system will save that information. You may then look at serial number reports (under reports -> inventory reports -> serial number sales) or use the track serial number tool under tools -> track serial numbers to view information on a specific serial number or on general serial number sales.
