UPI QR Codes in GST Invoices

GST Pro allows you to add a UPI QR code to your invoices, enabling customers to make payments instantly by scanning the code.

This is especially useful for B2B orders, where quick and accurate payment collection is important.

⚠️ Note: This is an advanced feature. If you're unsure about setup, feel free to contact support for assistance.

```
