GST Invoice Verifier — what it does
Reads GST invoices from PDFs or scans on your own machine, extracts the GSTIN, invoice metadata, HSN line items and totals with a confidence score on every field, then validates them — check digits, tax type, totals adding up. Built for the GSTR-2B reconciliation step where a wrong GSTIN means a disallowed credit.
How to use GST Invoice Verifier
- Drop in the invoice PDFs or scans. Text-based PDFs are read directly; scans go through on-device OCR.
- Review the extracted fields. Each one shows its confidence score and the region of the page it came from, so you can verify against the image without hunting.
- Fix anything below the confidence threshold — a smudged GSTIN or a rotated scan is exactly where extraction fails.
- Run validation: GSTIN check digit, state code consistency, CGST+SGST versus IGST, and taxable value plus tax against the invoice total.
- Approve the verified set and export CSV or JSON for your purchase register, with an audit trail of what was changed and by whom.
Worked example: the credit that would have been reversed
One invoice out of ninety in a vendor batch has a GSTIN whose last character is wrong — the invoice prints the check digit badly and OCR reads an 8 as a B. Validation flags it, you correct it against the image, and a ₹40,000 credit stays claimable instead of being reversed in the next return.

Frequently asked questions
- What is GST Invoice Verifier?
- Full on-device GST invoice verification: extract GSTINs, invoice meta, HSN line items and totals from PDFs or scans — every field with a confidence score and source region — then validate GSTINs, cross-check tax type and totals, review low-confidence fields, approve and export verified CSV/JSON with an audit ledger. No uploads, no LLM key.
- Is GST Invoice Verifier free to use?
- Yes — GST Invoice Verifier is free to use, with no sign-up, no install and no account.
- Does GST Invoice Verifier upload or store my data?
- No — GST Invoice Verifier runs entirely in your browser, so your text, files and results never leave your device.
- Do I need to install anything to use GST Invoice Verifier?
- No — it works in any modern browser (Chrome, Edge, Firefox, Safari) with no downloads, accounts or plugins.
- Do I need an API key or an AI subscription?
- No. Extraction and validation run locally with the browser's own PDF and OCR engines, which is what makes it usable for client invoices that cannot be sent to a third-party service.
- How accurate is the extraction on scanned invoices?
- Clean text-based PDFs are near exact. Scans depend on scan quality, so every field carries a confidence score and the low-confidence ones are meant to be eyeballed — the tool is designed so that review is fast, not so that review is unnecessary.
- What does the audit ledger record?
- Every field you change, the original extracted value, the final value and when it happened, exported alongside the data. When someone later asks why a figure differs from the paper invoice, the trail is already there.
