I can share some information about the e-invoicing feature in QuickBooks Online (QBO), @chandraiah-c-i-e.
E-invoices is available in QuickBooks Online (QBO). You can receive online payments on your invoices using Razorpay. You’ll just have to connect your existing Razorpay account or sign up for a new account and connect it to your QBO account.
For detailed steps on setting up your Razorpay account, activating, and connecting to your QBO account, refer to the following article: Payment enabled invoices—Razorpay.
You can always go back to this thread if you have follow-up questions in setting e-invoices and or anything else, by leaving a reply below. I'm always here to assist you. Take care and have a great rest of the day!
