Many barcoding systems will put the barcode that is scanned into whatever field the user has the cursor in. This holds true for AccountingSuite.
AccountingSuite has a barcode field on the item records. Scanning a barcode that is connected to the computer that is being used with AccountingSuite will result in that barcode number being entered in the field where the cursor is located. Here's how to set that up:
1) In your item code, enter the UPC code for that item in the UPC field. Save and close.
2) When you want to put that item on an order or other document, put the cursor in the code field and scan the barcode on the item.
