- GST rate is not embedded in HSN/SAC master data. Confirm the latest rate from GST rate notifications and official CBIC schedules.
- Invoice accuracy matters: use the code that best matches the principal supply description to reduce notices and mismatch risk.
- If supplies include both goods and services, document the dominant nature of supply before selecting HSN/SAC.

Compliance checklist

- Review code selection whenever scope of work or product mix changes.
