How it works

Three steps from a client's downloads to a reply you can review and file.

Upload the returns

Drop in the GSTR-1, GSTR-3B and GSTR-2B files as downloaded, and optionally the purchase register for invoice-level ITC matching.

Review the mismatches

Every difference by month and tax head, with exact amounts and a likely reason: timing, wrong tax head, supplier not filed, excess ITC.

Edit and file the reply

Download a draft ASMT-11 in Word, citing Sections 73/74 or 74A for the financial year. You review, sign and file it yourself.

Made for scrutiny work

The checks your team does by hand in spreadsheets, done in seconds and explained in plain English.

Deterministic reconciliation

GSTR-1 vs 3B and 3B vs 2B, per month and per tax head (IGST, CGST, SGST, cess). Exact to the paisa.

Invoice-level ITC matching

With the purchase register, see which supplier invoice is missing, late or different in GSTR-2B.

Timing differences found

Offsetting months are paired automatically, so you can show the officer that the net effect is nil.

Draft reply in Word

A structured ASMT-11 draft with difference tables, clearly marked items that need your judgement, and the right section for the year.

For your whole team

One firm account, separate logins for staff, and usage you can see each month.

You stay in control

The tool never logs in to the GST portal and never files anything. Every output is a draft for professional review.

Zero retention

Your clients' data is not kept.

The tool is designed so that client data cannot pile up: files are read in memory, and results disappear on their own.

Uploaded files are processed in memory and never written to disk or a database.
Results are encrypted and deleted automatically, or immediately when you click "Delete now".
Optional AI drafting sees only masked facts: no names, GSTINs, document numbers or amounts.
No GST portal credentials, ever. Logs never contain client data.
