Let me route you in the right direction so that you can add a QR code to your invoices in no time.
You can use QuickBooks third-party applications or other software that can add QR codes to your sales forms. This way, your customer can begin to pay you by scanning the barcode.
Thank you. Based in Malaysia, we have a bank national QR code to allow eWallet bank or other vendors (TouchnGo, Boost, etc) payment. Currently, we are putting up a link on the invoice for customers to click on and go to our website to scan the QR code, would like to simplify the steps, hence trying to make the QR code image appear on the invoice itself, hopefully, can be done.
