What your business gets
Purchase register vs GSTR-2B vs IMS. Per-line MATCHED / MISMATCHED with precise mismatchType (taxable / tax / rate / place / date / RCM). Every dispositioning decision carries a Section + Rule citation.
Every filed return ships an HMAC-signed receipt. Public verifier route at /verify-gst/<token> lets your auditor confirm the receipt was issued by the platform with the same payload printed on the PDF.
DRC / ASMT / REG / GST notices ingested with the full lifecycle. Draft your reply inline, attach supporting documents, and the cron sweep nudges anyone with an outstanding ask before the due date.
Monthly + quarterly QRMP + composition + annual + cancellation periods open with the correct due date encoded in one place. The 11th / 13th / 18th / 20th / 22nd / 24th rules ride the period spine automatically.
XLSX, CSV, Tally, or manual entry. Every line lands as PurchaseRegisterLine with the supplier GSTIN + document number encrypted at rest. Bulk imports get a dedupe pass before the matcher runs.
GSTR-5 / 5A / 6 / 7 / 8 / 9 / 9C / 10 plus ITC-01 / 02 / 03 / 04 ship via a single polymorphic surface. Each form picks its own headline totals, captures payload as JSON, gates submit behind step-up OTP, and records the ARN.
How it works
The hexagonal port stays in place so a paid GSP can swap in by one env flip when volume justifies the spend (~1,000 filings per month). Until then, submissions route through your portal credentials under step-up auth.
Step 1
Add your GSTIN to the platform. Encryption + fingerprint runs at the boundary; the plaintext never touches Prisma. Direct-B2C deductors hold their own GSTIN, CA firms file for a roster of business clients with explicit consent.
Step 2
The period spine opens monthly / quarterly / annual rows on the canonical CBIC schedule. Pull GSTR-2B, ingest your purchase register, run the three-way matcher, decide on every disputed line.
Step 3
Store your gst.gov.in credentials in the AES-256-GCM envelope once. Every submit unlocks the envelope ephemerally under step-up OTP, posts to the GSTN portal, captures the ARN, and prints the signed receipt.
Pricing
Includes every form your GSTIN files, ITC reconciliation, the notices inbox, signed receipts, and the polymorphic supplementary forms surface. CA review priced separately on assignment.
