For CA Firms and Business Owners — GSTR-2B Reconciliation

Know exactly which ITC you can claim
and which is still at risk. Instantly.

Section 16(2)(aa) of the CGST Act says ITC can only be claimed when the invoice appears in your GSTR-2B. GSTAgent reconciles your Tally purchase register against GSTR-2B from the GST portal — automatically — so you know which invoices are safe, which are missing, and exactly what to do about each one.

The reconciliation problem

ITC that is not in GSTR-2B cannot be claimed — but most CAs only find out after filing

📥
Manual JSON downloads
Every month, you log into the GST portal, download GSTR-2B as a JSON file, open it somehow, and try to match it against your purchase register. There is no standard tool. Most CAs use Excel VLOOKUP — which breaks the moment an invoice number has a small format difference.
⚠
Wrong ITC claims
If you claim ITC on an invoice that is not in GSTR-2B, the GST department will issue a notice under Section 73. The demand includes the ITC amount, interest at 18% per annum from the date of claiming, and a penalty. This is one of the most common GST notices CA clients receive.
📞
Late supplier follow-up
When a supplier has not filed their GSTR-1, their invoices do not appear in your GSTR-2B. If you do not catch this early, you either claim the ITC and get a notice, or miss the September deadline to claim it at all — losing the ITC permanently.

What makes GSTAgent different

Not another Excel replacement — a real automation

✓
No file downloads — ever
Every competitor requires you to download GSTR-2B as a JSON file, then upload it somewhere. GSTAgent connects directly to GSTN via the official API. One OTP, one click, done. The same goes for Tally — no CSV exports, no manual uploads.
✓
9 match statuses, not just matched or unmatched
MATCHED, SOFT_MATCH, INV_CONFLICT, MISSBOOKS, UNREPORTED, TIMING_PENDING, DUPLICATE_PR, GSTR2B_ONLY — every invoice gets a specific status with a specific action, not just a red or green colour.
✓
Full year reconciliation — all 12 months at once
Upload GSTR-2B for all 12 months in one go. GSTAgent tracks which months are loaded, which invoices are timing differences vs genuinely missing, and shows the full year's ITC position in one view.
✓
ITC at risk quantified in rupees
Not just "invoice not in 2B" — GSTAgent tells you exactly how much ITC is at risk (₹X) and what happens if you claim it anyway (Section 73 demand with 18% interest). The CA knows precisely what is at stake.
