Can the UPI scan code can be placed in the invoice in quick books?

It's nice to see you here in the Community, @gowthami-jaa-ass.

Making sure you include all sales info when sending an invoice to your customers will surely make processing payments easy. However, the option to include a UPI scan code in your invoice is unavailable in QuickBooks Online (QBO). 

As a workaround, you can look for a third-party app that integrates with QBO. To do so, please follow these steps:

1. Head to the QuickBooks Apps store at this link.
2. From the search bar, enter a keyword of the feature you need. Example: Scan code. 
3. Then, press the Enter key on your keyboard.

I also encourage you to visit our QuickBooks Blog page to keep you updated on the latest news of the product. From there, you'll see newly released features and other resources that'll help manage your business. 

QuickBooks also makes it possible to personalise your sales form to reflect more of your business identity. For the detailed guide, please check out this link: Customise invoices, estimates, and sales receipts in QuickBooks Online. 

If you need further assistance adding scan code on your invoice forms, feel free to post a reply below. I'm always here to help. 

You may utilize this payment processor to integrate with your QBO account as a workaround. Once your customer receive your invoice, they will be prompted to choose the mode of payment from Card, Net banking, Wallet, and UPI.
