Free tool · No signup

Find what's wrong before the GST portal does.

Upload your Purchase Register and your GSTR-2A/2B download. We compare every invoice and tell you in plain English what's missing, mismatched or duplicated — and what to do about each one.

🔒 Runs entirely in your browser. Your files are never uploaded to any server.

How we match: GSTIN + Invoice No. is the match key. Formatting is ignored, so GPC/1145, GPC-1145 and GPC 1145 are treated as the same invoice. Amounts written as text (₹1,50,000) are read correctly.

What we flag: invoices your vendor hasn't filed, taxable-value mismatches, tax-amount mismatches (wrong rate), IGST vs CGST/SGST mix-ups, duplicates on either side, single-character GSTIN or invoice-number typos, credit notes, and portal entries missing from your books.

Tolerance: differences up to ₹5 are treated as rounding, not errors.

What we cannot check: whether an invoice date falls inside your filing period, whether a vendor's GSTIN is genuinely registered, or anything about returns you've already filed. We also can't catch a typo that appears identically in both files.

This is a screening tool, not a filing decision. Confirm every flagged item with your accountant before you file.

This is one leak. There are usually more.

Reconciliation is where it shows. It's rarely where it starts.

Invoice processing, order handling and approval chains quietly cost most SMEs far more hours than GST filing does. A free efficiency audit shows you exactly where yours go.
