What is GSTR-2B vs books reconciliation?

It is the process of matching the input tax credit shown in your GSTR-2B (or 2A) against the purchases recorded in your books, so you claim only eligible ITC. The reconciliation highlights invoices that appear in 2B but are not booked, entries booked but not reflected in 2B (a potential reversal), and matched invoices where a value differs.

Is my data uploaded anywhere when I use this tool?

No. The entire reconciliation runs inside your own browser. No invoice, GSTIN or financial data is sent to any server or uploaded anywhere.

What files do I need to use the reconciler?

Two sides, each as Excel or CSV. The 2B / 2A side should contain columns such as GSTIN, party, invoice number, invoice date, taxable value and GST. The books side should contain GSTIN, date, particulars, voucher number, the GST as per Books column and optionally a taxable value column. Column order does not matter; the tool detects the headers.

Can I file my GST return based on the auto-match?

No. The tool assists reconciliation but is not a substitute for professional review. Always review the flagged rows before claiming or reversing ITC; for a reviewed reconciliation, speak to a Chartered Accountant.

Financial year

How matching works & limits

Match order: GSTIN+invoice or exact invoice+amount → exact invoice → financial-year variant (562/2025-26 = 562/25-26) → invoice-number typo → same amount + party (name or GSTIN) + date within 12 days. The amount check column = 2B tax − GST as per Books, and its total equals the 2B-minus-books gap — if the tie-out is red, something in the import is malformed. GSTIN check confirms the supplier; when GSTIN matches, a name difference is not flagged.

It cannot tell "in 2A but not 2B" apart (no 2A feed) and won't auto-decide "booked twice / wrong rate / without tax" — review the flagged rows. Don't file on an unreviewed auto-match.
