NEED INVOICES TO TECHMANTRA BY QUICKBOOKS

Hi there, @rashmihegde-jaa-. I'm here to help you manage your invoices.

To clarify, is Techmantra a third-party app linked with QuickBooks? I'd recommend reaching out to their support if you're having sync issues.

Otherwise, if you need to add Techmantra GSTN on invoices, you can follow these steps:

1. Go to the Gear icon and choose Custom form styles.
2. Click the Edit link on the invoice template. 
3. Select the Content tab.
4. Scroll down towards the Form names and Display section, then put a checkmark next to the Customer GSTIN box. 
5. Click Done once finished. 

You can refer to this article on how to make your invoices GST compliant:

Feel free to come back to this thread and post a reply below if you need further assistance, @rashmihegde-jaa-. It's my priority that you find the success you need.
