Powerful inside. Simple outside.

Upload 2B & books — we standardize everything

Drop the GST portal GSTR-2B (JSON or Excel) and your purchase register (Excel/CSV from Tally, Busy, Zoho or any ERP). Auto column-mapping, GSTIN checksum validation, duplicate detection and sign normalization for credit notes.

  • Reads all 2B sections: B2B, CDNR, ISD, IMPG, amendments
  • Auto-maps your register columns via synonyms
  • Validates GSTIN format + checksum on every row

A deterministic reconciliation engine

Every match explains why it matched. Exact, strong-probable and amount-based stages with configurable amount and date tolerances, fuzzy invoice-number matching, and cross-month carry-forward for late supplier filings.

  • Match score 0–100 with reason & mismatch fields
  • Tax vs taxable vs invoice-number vs date mismatch split
  • Vendor GSTIN mismatch & duplicate detection

Freeze the month, claim with confidence

Review the GSTR-3B support summary, finalize the ITC claim, then freeze. Freezing stores an immutable snapshot — records, matches, actions and ITC position — that can only change through an explicit, audited revision.

  • Pre-freeze checklist before locking
  • Head-wise ITC summary (IGST/CGST/SGST/Cess)
  • Carry-forward + vendor follow-up across months

For each mismatch, you instantly know…
