How it works

Three steps, no sign-up

  1. 1

    Check what you have

    Paste a GSTIN, upload the QR from an e-invoice, or enter a whole invoice. No sign-up.

  2. 2

    See what is wrong, and why

    Every problem names the rule it breaks, so you can check it yourself or show your CA.

  3. 3

    Fix it, or chase it

    Correct your own invoice before you file, or ask the supplier before you pay them.

Questions

Frequently asked questions

Free checks are processed in memory and never written to our database — nothing about that invoice is kept. The GSTIN and e-invoice QR checks at the top of this page run entirely in your browser, so nothing is uploaded at all. If you pay for a full report, we do store the invoice details, because that is what lets you re-open, download and email the report afterwards. We never sell your data or use it to train AI models, and you can ask us to delete a stored check at any time.

No, and it is not meant to. We run 16 mechanical checks on the invoice itself — GSTIN structure, tax head against place of supply, HSN, the arithmetic, invoice numbering and dates. That is the tedious layer, and it is the layer that gets returns rejected on upload. Judgement calls, classification, notices and the return itself are your CA's work. It is built to clear the mechanical errors before the professional review starts.

Nothing here depends on it. Every check runs on the invoice itself — GSTIN structure and checksum, tax arithmetic, HSN, numbering and dates — so it works whether the portal is up or not. The one thing only the portal can tell you is whether a GSTIN is currently active, and we link you to the portal search for that.

Not directly. You can check any invoice you have generated before you upload it to your buyer or marketplace, or run a whole batch at once on the bulk page.
