Catch GST errors before the department does
The GST Error Catcher scans your invoices for the mistakes that trigger notices — IGST charged where CGST+SGST applied (or vice-versa), wrong HSN/rate pairings, rate anomalies on the same product, missing HSN above the threshold, and duplicate invoices — all offline.
Place-of-supply errors are the #1 cause of GST notices; this finds them while you can still fix them.
Place-of-supply guard
Flags invoices where the wrong tax head was charged for the company-vs-party states.
HSN & rate anomalies
Same product billed at different rates, wrong HSN/rate pairs, missing HSN above the turnover threshold.
Duplicates
Duplicate invoice numbers and same party+amount+date repeats are surfaced.

Frequently asked
Why focus on place of supply?
Charging IGST on a local sale (or CGST+SGST on an inter-state one) is the single most common GST notice trigger — so it’s the first thing checked.
Does it change my invoices?
No — it only flags issues for you to review and correct.
