I appreciate your thoughts and ideas about having a QR code in your invoice, Jane.
As of now, having this option isn't possible in QuickBooks Online (QBO). As an alternative, you can visit our QuickBooks Apps page and look for a third-party app that lets you add QR code to your invoice.
In addition to this, you can also check this article for complete guidelines in personalising your sales form: Customise invoices, estimates, and sales receipts in QuickBooks Online.
Tag me in your reply if you have other follow-up questions customising your invoice. I'm always here ready to back you up!
