Hi @nikonex3 - welcome to QB Community!
I've never personally used a barcode scanner but it sounds like you may still be considering your options as to what system might work best for you at the shop. If you haven't yet done so, you may want to check out The Basics of Inventory Management, our series of short nuts-and-bolts informational articles.
Any members out there use barcode scanner for inventory? Pluses, minuses?
