i need help for technical issue on QB e-Invoice. QB showing pending validation for the invoice however after log in to LHDN portal, it shows error invalid TIN

Hello, Guatben. The error you're encountering usually happens when there is missing or incorrect information within your customer's profile. To fix this, we should first verify that your customer’s profile is set up correctly.

To do this, please navigate to Allapps > Customer Hub > Customers. From there, locate the customer associated with the invalid TIN error and click Edit to review their details. Ensure the TIN and other tax details are accurate, and update them if necessary.

However, if the customer information is already correct, you can delete the e-invoice that was rejected and re-create and send it again to validate it with LHDN. If the result is still the same, you can follow the QuickBooks prompts to resolve the issue why it is rejected.
