Greetings, @Mazin Abdalla.
I'm happy to share with you some information about QR codes in QuickBooks Online(QBO).
Currently, QR codes are not available in QuickBooks Online. However, you can use a third-party app.
As mentioned by one of my colleagues above, you can contact the developer and ask them to contact QBO to have the app synced.
Since there is no specific time yet as to when this feature will be added, you can visit the QuickBooks blog to know more updates.
You may also check the Payment Links in QBO Payments for more payment options.
If you have more questions about a QR code, just click on the Reply button below. I'm always around to help.
