Thanks for following up with the Community, Carabeo Brothers.
 

I'm happy to hear RoseMarjorieA was able to help. You'll be able to find many useful applications in our QuickBooks App Store.

I can certainly understand how having an ability to enter a QR code on invoices could be useful to yourself and others. My colleague, JasroV, submitted a suggestion about this to our Engineering Team on October 1, 2020. I've also sent feedback about it as of today.

If you'd like to send your own feature requests to our developers, you can do so while signed in.
