Hello i want to add QR any body can guide me please

Thanks for visiting us here in the Community, dieseltechno1-gm.

The option to include a QR code is currently unavailable in QuickBooks Online. In the meantime, you may consider looking for a third-party app that offers to add QB codes to sales transactions. You can use this link to find the app that suits your needs: QuickBooks App.

If you need assistance with modifying the layout of your sales form, please see this article for additional information: Customise invoices, estimates, and sales receipts in QuickBooks Online.

Do you need to return a customer's money? If so,  I've included this resource for future reference: Record a customer refund in QuickBooks Online.

Don't hesitate to add any details below if you have further questions about QR codes or other QuickBooks concerns. We're always available to assist you.

You may need 2 free apps to integrate with QBO as a workaround. Where is your company located?
