I am currently testing a palm 1500 to scan in items to my vouchers the problem is because of our product mix the vendors always substitute the items or send the incorrect product. Now if the item already exist on my database it is going to show up as received inventory is there a solution to only scan the items that I order and receive them only I do not want to be stuck with items I did not purchase .I am getting quotes in the thousand of dollars which is way beyond my budget with this tight economy down turn there must be another solution that already exist for my store
