How to do e-invoicing in Quick Book India?

Hello there, @rakeshv-a5econsu.

Allow me to share some information about the e-invoicing in QuickBooks Online.

We can enable the online delivery option so you can add e-invoicing to your company. Follow the steps below to enable this one:

1. Click the Gear icon at the top of the main page.
2. Select Account and Settings from the drop-down menu under Your Company
3. Tap the Sales tab. 
4. Tick the box for Online delivery.
5. In the Additional email options for invoices, choose Online invoice.
6. Hit Save and press Done.

Once done, you can send an e-invoice in QuickBooks Online (QBO). You can also 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.
