Go to Your Orders from the top menu or "Account & Lists".
Locate the order you need the GST bill for and click Invoice (or View invoice).
If the invoice includes GST details, click the Download PDF button to save it.
You can also go to Your Invoices and select the order to download the GST‑inclusive invoice.
Make sure your GSTIN is verified in Account & Lists > Your Account > Tax Settings; otherwise the invoice may lack GST information.
If the invoice is missing GST, contact Amazon Seller Support via Help > Contact Us and request a manual GST invoice.
*Tip:* Amazon automatically generates a GST‑compliant invoice once your GST details are recorded in your account. If you don't see the GST component, verify the GSTIN or reach out to support for assistance.
