Sample GST e-Invoice Technical Readiness Review
Prepared by the ConstaLabs AI agent. This example uses synthetic, non-confidential data.
The sample invoice is not technically ready for the next integration step. Three deterministic schema issues should be corrected before another validation run.
1. Missing HSN/SAC classification
Location: items[0].hsn
Correction: Supply the applicable HSN or SAC code selected by the business or its tax adviser, then confirm that the configured validator accepts it.
2. Buyer GSTIN format
Location: buyer.gstin
Correction: Replace the incomplete value with the verified buyer GSTIN. Missing characters must not be inferred or fabricated.
3. Taxable-value reconciliation
Locations: items[0].taxableValue and totals.taxableValue
Correction: Recompute the header value from final line-level amounts under the agreed discount and rounding rules.
Recommended correction order
- Verify the buyer GSTIN and applicable HSN/SAC master data.
- Correct the line item.
- Recalculate invoice totals.
- Run local schema validation again.
- Review the result before any production submission.
Scope limitations
This is technical validation, not tax or legal advice, IRP submission, IRN generation, QR-code generation, or confirmation by a tax authority.
