Match Books with GSTR-2B.
Up to 99.99% Accurate. Zero Hassle.

GST reconciliation is the process of matching your Purchase Register (Books) with GSTR-2B data from the GST portal to identify mismatches in invoice numbers, tax amounts, and GSTINs. It ensures every rupee of Input Tax Credit (ITC) you claim is backed by matching supplier invoices — a mandatory check before filing GSTR-3B.

Yes, GST Reconcile is completely free during launch. No signup, no credit card, no hidden charges. Upload your two Excel files and get results in seconds.

GST Reconcile goes beyond exact text matching. It normalizes invoice numbers (handling slashes, hyphens, leading zeros), detects date format differences (DD/MM/YYYY vs YYYY-MM-DD), and identifies character confusion (0 vs O, 1 vs l). Every match shows the reason, so you can verify it yourself. The result is up to 99.99% matching accuracy.

Upload your Purchase Register and GSTR-2B as Excel files (.xlsx). The tool auto-detects columns like GSTIN, Invoice Number, Date, and Taxable Value — no manual mapping needed.

Your data is always private and secure. We DO NOT store, save, or retain your data on our servers.

VLOOKUP only does exact string matching. If the GST portal reformats your invoice number (e.g., INV/2026/0341 becomes INV20260341), VLOOKUP says 'no match.' GST Reconcile uses smart matching to catch these variations automatically — saving hours of manual work per client.

Ideally, reconcile every month before filing GSTR-3B. This gives you time to identify mismatches, contact vendors for corrections, and ensure your ITC claim is accurate. Most CAs reconcile in the first week after GSTR-2B is generated (typically 14th of each month).

Mismatched invoices mean your ITC for those invoices is at risk. Common causes include invoice number typos, date format differences, and vendors not uploading invoices to their GSTR-1. GST Reconcile flags every mismatch with the exact reason, so you know whether to follow up with the vendor or correct your books.
