Duplicates that cost you

Flags duplicate vendor masters (same GSTIN / PAN / name), the same payment made twice in a short window, and a bill number entered more than once — the classic double-ITC and double-payment leaks.

Manual-manipulation signals

Surfaces suspiciously round high-value amounts, vouchers entered long after their document date (backdating), and purchases or payments dated on weekends — the patterns manual manipulation leaves behind.

ITC you can’t safely claim

Catches input tax credit claimed with no supplier GSTIN or at an impossible GST rate, so a shaky claim is reviewed before it is filed.

Frequently asked

Does this use AI or send my data anywhere?

No. Fraud detection is a set of deterministic rules that run entirely on your machine over the books you already have — no LLM, no internet, no third-party service. Every re-run yields the same findings.

What does it actually check?

Duplicate vendors (shared GSTIN/PAN/name), duplicate payments and duplicate bill numbers, suspiciously round high-value amounts, backdated vouchers, weekend-dated purchases and payments, and ITC claimed with no GSTIN or an impossible rate.

Will it change my data automatically?

Never. Every finding is guidance for review, linked to the exact document — you decide what to do. Nothing is auto-corrected or auto-posted.
