Direct verification of GSTIN, document type, and invoice numbers. Catches standard, clean data transactions immediately with zero ambiguity.
Matches "INV-2024-001" against "INV-2024-001"
02
Pass 2: Cleaned Match
Strips special characters, symbols, white spaces, financial year tags (such as /24-25, FY24-25) and leading zeros. Evaluates numerical invoice cores to overcome variations in billing formats.
Cleans and matches "INV/24-25/098" against "INV098" (Core: "2425098")
03
Pass 3: Fuzzy Match
Applies Levenshtein distance calculations within GSTIN buckets. Identifies typos, formatting offsets, or sequence variations within a configurable threshold.
Matches "TCS-992-A" to "TCS-992B" at 88% similarity score
RECONCILIATION SUITE SCOPE ACTIVE

Enterprise-Grade Data Reconciliation

Modern GST filing reconciliation requires verifying multiple ledgers. The GSTR Reconciliation Suite maps and cross-validates records across three major categories: GSTR-2B, GSTR-1, and GSTR-3B.

  • GSTR-2B vs Books: Inward ITC reconciliation (Flagship module).
  • GSTR-1 vs Books: Sales return matching & filing integrity.
  • GSTR-3B vs 2B & 1: Monthly summary claim tax validation.

SUITE MODULE CONTROL CENTER
