I have 1,000's of parts in stock and most of the items I keep have bar codes on them! So when I am booking parts out to a customer how come I can only bring that part into the invoice screen by typing in my part number?  There is a section within the product screen for a bar code for each item so surely now bar code scanners are in constant use it would be far easier to scan each of the stock items I am selling to that customer into the Product invoice screen rather than type a sometimes very long part number? I could overcome this by changing every one of my part numbers to the bar code number, but as I said I have 1,000's of products in stock and this would take weeks to do along with losing all the existing sales data for each product!
