Thanks for visiting the Community today, @ourmaninindia.
I know how relevant for you to add the customer's name and SAC codes in the GSTR2 - 3.
At the moment, you can only add SAC codes to your products and services.
You can also add SAC codes or import SAC codes in volume for existing products. Check out this link for your reference: How to add HSN and SAC codes to your products and services.
Feel free to visit the Community again if you have additional concerns. We're always around here to help.
Thanks for getting back to us, ourmaninindia.
I can see how useful for you to add the customer's name and SAC codes in the GSTR2 - 3. However, there are certain limitations for each product offered by Quickbooks.
As mentioned by my colleague, you can only add the SAC codes to your product and services. You may follow her outlined steps on how to add them.
We aim to find new ways to meet your needs. I'd suggest visiting the Quickbooks Blog to stay updated on any improvements in the software.
Please keep in touch if there's anything else I can do to help you succeed with QuickBooks. I've got your back.
