Thanks for joining the conversation, @markcrobinson,

If the column will not allow you to assign the barcode that's compatible with your scanner, you may use the Attachment feature for it. For this, you will need to save the barcode as a file or image. This attachment will work when you email the sales transaction to a client.

To do that, follow the steps below:

1. On the Sales Receipt, click the Attachment button at the top.
2. Select a source where the barcose is saved.
   
3. Pick the file and mark it before clicking Done.
   

Please note that attachments will not print together with the sales transaction. If you want, we have third-party applications you can check that supports this preference. Check them out there: https://desktop.apps.com/home

We also have a separate forum called Intuit Developers, where you can find engineers who can help recommend third-party applications for you to use. In this website, you can connect with developers who can help with app integrations, take part in software developments and innovate business tools for QuickBooks.

Here's the link to the website: Intuit Developers Community.

Feel free to get back to us if there's anything else you need help with. I'll be glad to help you at any time. Have a nice day!
