As a re-seller will I need a barcode production?
When I purchase inventory will I need to produce my own bar codes or is it not necessary. An if its not necessary would I just need a scanner?

Best answer:

You don’t need your own bar codes unless you want them. A scanner would work if you want to use the coding that is already there. When I resell, I ignore the bar code and charge my own price.
