Hi,I am a user in Singapore.I would like to know how to generate & display PayNow QR code directly on my invoices.

QuickBooks Online doesn't currently have a built-in feature to generate or display a PayNow QR code directly on invoices. However, you can use a third-party app to add this functionality. Just head over to the Integrations icon in the upper right corner. From there, select Find integration and search for an app that fits your needs.

Feel free to return if you have follow-up questions.
