Both return a 100-point score and a risk band used for prioritisation. - Cadence: exposure is flagged in real time, every GSTIN is re-evaluated daily, and score changes are intimated on a near real-time basis. - Risk scores published by GST First are indicative and must not be presented as credit ratings, statutory determinations or assurances of ITC eligibility. - Data is sourced from public GST registration and return records via licensed providers, and every record carries a last-synced timestamp. - Authenticated application routes (/app, /admin, /profile and similar) are private.
