Hi GlennRene,

We have received reports from other customers with regard to quantity not increasing using the barcode scanner. With that, I recommend reaching out to our phone support so we can add you to the list of affected users. Here's how:

1. From the Help menu, select QuickBooks Desktop Help.
2. Click Contact Us.
3. You can type in Scanning Barcode in the QuickBooks Desktop mobile app does not increase quantity.
4. Click Continue.
5. You can choose to either Chat with us or Have us call you.

Moreover, you can use QuickBooks Scan Manager to scan receipts and documents and then attach them to your transactions. Here's an article as your guide:  QuickBooks Scan Manager: Scan and attach documents to transactions.

We appreciate your patience while we resolve the issue as soon as possible. I'm always around whenever you have concerns about tracking inventories.
