AI GST Invoice Checker
Check a supplier's invoice before you pay or claim credit. Every finding shows what was read from the document.
How to use the AI GST Invoice Checker
- 1Upload the invoice.
- 2We read it and run GST checks in code.
- 3Review PASS, WARNING or NEEDS REVIEW findings.
What's checked
Invoice number and date, seller and buyer GSTIN format and check digit, HSN/SAC on each line, line arithmetic, tax at the stated rates, equal CGST and SGST, IGST vs CGST/SGST against the two GSTINs' states, the grand total, and duplicates you've already checked.
What it doesn't do
It can't confirm a GSTIN is registered, that the rate is right for the product, or that the supplier has filed their return. It flags potential issues — it doesn't certify an invoice as compliant.
How your document is handled
Your file is sent over an encrypted connection to BolHisab and to an AI provider that reads it, processed in memory and not stored by BolHisab. BolHisab does not use your files to train models. Every figure the AI reads is then checked by deterministic code, and anything unclear is marked “Needs review” instead of being guessed.

Why check supplier invoices?
Why check supplier invoices?

Is the check AI?
Is the check AI?
AI only reads the document. All checks are plain arithmetic and rules.
