GSTR-2B Reconciliation Automation With AI: How It Works

The matching problem

Invoices rarely match perfectly: typos in invoice numbers, date differences, tax rounding and supplier GSTIN changes.

A modern approach

1. Import purchase register and GSTR-2B JSON
2. Normalise invoice numbers and GSTINs
3. Exact match, then tolerance and fuzzy match
4. Flag mismatches by reason (missing, amount, period)
5. Create supplier follow-up lists and claim recommendations

Controls

Keep a human review for ITC claims, log decisions, and store working papers for audits.
