Return preparation is easier when supplier, recipient, place-of-supply and tax components are captured on the source transaction.
Capture transaction context
Record GST identity, state codes, place of supply, reverse-charge indicator and HSN or SAC alongside the document and line snapshots.
Expose exceptions early
Missing document numbers, GST identities or place-of-supply values should appear in a readiness exception list before return work begins.
Keep the boundary honest
Readiness datasets are not GSTN filing and do not establish statutory compliance. Qualified external validation remains necessary.
