Each different product you sell requires its own barcode. For example, if you sell a t-shirt that
comes in one color and 3 different sizes you would need to buy 3 barcodes. If the t-shirt comes in 2
sizes and 3 colors you would need 6 barcodes. This way, if one of the colors/sizes is selling faster
than the others, the store can simply look in their computer and see which one needs to be
replenished without having to do a manual shelf count. This same formula applies for all styles,
colors, flavors, sizes or any other variation of your product. They all need their own unique
barcode.
