I have selected the correct state in my shipping address, but it says the state code does not match with the GSTIN. What should I do?

The above error indicates a mismatch between the state code in the address and the state code in the GSTIN of the customer. This occurs when the billing address and shipping address have different states, and the address has been entered directly in the Billing Address/Shipping Address field while creating a contact or transaction. To resolve this, follow these steps:

1. The shipping address needs to be added as an additional address. To add it:

   • Go to Sales on the left sidebar.
   • Navigate to the Customers module at the top.
   • Locate the customer to whom you want to add the additional address and click Add additional address in the Overview page.
   • Enter the details and click Save.

2. To update the shipping address in the invoice:

   • Go to Sales on the left sidebar.
   • Navigate to the Invoices module at the top.
   • Select the invoice that you were not able to push to the IRP and click Edit.
   • Click the Edit icon near Shipping Address and select the newly added address from the list.
   • Then, edit the Billing Address and select the address again.
   • Click Save.

Now, you can push the invoice again to IRP without facing any error.
