For an Indian SaaS or IT-services exporter, the GST file should connect each export invoice to the underlying service and recipient, the applicable export route, return reporting, and—if seeking a refund—evidence that the consideration was received. A customer’s overseas address alone does not establish that a supply qualifies as an export of services. Keep goods-export customs documents separate from the service-export checklist.

Start by confirming the supply qualifies as an export of services

Export of services is a zero-rated category under the IGST Act, but “the customer is abroad” is not a complete legal test. Check the applicable statutory conditions against the actual contract, recipient, supply and establishment facts before applying export treatment. SaaS delivery models and contract structures can differ, so do not assume that every overseas subscription or IT-services engagement qualifies.

Keep a transaction file that makes those facts easy to review. As a practical recordkeeping set, retain the agreement or order, scope of work, service-period records, customer and recipient details, invoice, payment or remittance references, and related return or refund records. This is a useful way to organize evidence, not an exhaustive statutory document list.

Issue an export invoice with the correct particulars

CBIC’s GST invoice rules prescribe a route-specific export endorsement. Use the applicable wording:

  • When exporting on payment of IGST: “SUPPLY MEANT FOR EXPORT ON PAYMENT OF IGST”.
  • When exporting under LUT or bond without payment of IGST: “SUPPLY MEANT FOR EXPORT UNDER BOND OR LETTER OF UNDERTAKING WITHOUT PAYMENT OF IGST”.

The rules also call for export-specific particulars, including the recipient’s name and address, delivery address, destination country, and the export-removal application number and date in place of the referenced ordinary recipient particulars. Include the other applicable tax-invoice fields as well, such as supplier identity and GSTIN, serial number, issue date, service accounting code, and service description and value, as relevant.

Choose and document the export and refund route

GST portal guidance describes two routes, subject to applicable eligibility and filing rules. Which route is available or appropriate depends on the exporter’s circumstances; confirm current requirements for the specific GST registration before filing.

Route What happens Records to retain
Export without payment of IGST under LUT or bond No IGST is paid on the export under this route; the exporter may claim a refund of eligible unutilized input tax credit, subject to applicable conditions. Applicable LUT or bond evidence, export invoices, return records, and the records supporting the eligible ITC refund claim.
Export on payment of IGST IGST is paid on the export; a refund of that tax may be available subject to applicable rules and procedure. Export invoices, records of IGST paid and return reporting, plus the filing evidence required for the refund route.

The GST portal’s GSTR-1 guidance describes these broad options. Do not treat that overview as a guarantee of entitlement or as a substitute for checking current law and portal requirements.

Report invoices in GSTR-1 and reconcile the return period

Report export invoice details in GSTR-1 and retain the return acknowledgement and invoice-level reconciliation with the records for that period. The portal says invoice details can be reported even when shipping-bill number and date are not yet available, with those details added later by amendment when received. That facility is relevant to goods-export reporting; it does not make a shipping bill a standard requirement for a SaaS or IT-services export file.

For a services-export refund, link receipt evidence to the invoices

For a refund claim on account of export of services, the refund rules call for invoice numbers and dates and relevant Bank Realisation Certificates (BRCs) or Foreign Inward Remittance Certificates (FIRCs). CBIC’s Instruction No. 03/2022-GST also directs officers reviewing claims to verify BRC/FIRC or other relevant evidence of receipt of export remittances.

Keep the remittance reference and receipt evidence connected to the related invoices and claim period. The particular evidence that will suffice, and the portal upload process in force, should be checked when preparing the claim; neither should be assumed from a general checklist.

Do not copy goods-export paperwork into a services file

Shipping bills and Export General Manifests (EGMs) are part of goods-export customs workflows, not the core evidence set for exported SaaS or IT services. For example, an ICEGATE FAQ dated April 2026 says that, for IGST-paid exports of goods, the shipping bill is treated as the refund application and identifies the Shipping Bill and EGM as filing checks. The refund rules also refer to shipping-bill or bill-of-export and export-invoice details for goods claims. These goods-specific requirements should not be mistaken for the invoice-linked remittance evidence used to support a services-export refund.

Check whether e-invoicing applies to your registration

The GST e-invoice portal includes export transactions in its e-invoicing guidance and also describes exemptions. Whether an exporter must generate e-invoices depends on the current mandate, thresholds, exemptions and the taxpayer’s facts. Check the GST e-invoice portal guidance and current rules rather than assuming that all exporters—or no exporters—are covered.

Practical file checklist

  • Contract or order, service scope and period records, and details establishing the recipient and supply facts.
  • Export tax invoice with the correct payment-route endorsement and export-specific particulars.
  • Applicable LUT or bond evidence if exporting without payment of IGST.
  • GSTR-1 and return acknowledgement, with invoice-level reconciliation for the period.
  • For a service-export refund, invoice-linked BRC, FIRC or other relevant remittance receipt evidence.
  • Separate goods customs evidence from service-export records, and verify e-invoice applicability for the taxpayer.
