Retrieve Export GST Payment

I recently shipped goods out of India and both my supplier and the logistics company collected GST on their invoices. I would also want to retrieve my GST payments back from the Government. What I still need is the specific tax-filing record (an extract from their GSTR-1 or GSTR-3B) that shows my shipment details and the GST amount paid. I already hold the shipping bill, airway bill and the bank records confirming the foreign currency payment; I do not have the suppliers’ GST filings. Your role is to: • Liaise with the supplier and the freight forwarder (I will provide contacts) and obtain the relevant filing extract. • Cross-check the document on the GST portal to confirm its authenticity. • Deliver verified PDF copies together with a short note explaining how and when you verified them. Request for the refunds of my GST Acceptance criteria • The filing record must list my invoice or consignment reference and the exact GST amount. • It must carry the government filing acknowledgement number or portal time-stamp. • Your verification note must include the GST portal URL, date and time of access. A freelancer mostly a lawyer familiar with the Indian GST portal, GSTR returns and supplier follow-ups will find this straightforward. Fluency in any Indian language for smoother communication is welcome. I would like the verified documents within seven days of project start.
