About this GST Reconciliation Tool

This free online GST reconciliation tool from Kumar Keshav & Co., Chartered Accountants in Dwarka, New Delhi, matches your Purchase Register against GSTR-2A and GSTR-2B to find Input Tax Credit (ITC) mismatches, missing invoices and supplier-filing differences — and gives you a colour-coded, exportable report. It runs entirely in your browser, so your GST data never leaves your device.

How the GST 2A / 2B reconciliation works

  1. Select the period you want to reconcile (1 to 36 months).
  2. Upload your Purchase Register (use the built-in Excel template) — it is converted to JSON automatically.
  3. Upload your GSTR-2A and/or GSTR-2B exactly as downloaded from the GST portal — Excel or JSON.
  4. Run Purchase Register ↔ 2B (for ITC eligibility) or 2A ↔ 2B (for supplier-filing differences).
  5. Review the colour-coded report — exact match, approximate, mismatch, ITC at risk, or unclaimed — and export it to Excel.

Frequently asked questions

What is GST 2A/2B reconciliation?
It is the process of matching the purchase invoices in your books against the invoices auto-populated in GSTR-2A and GSTR-2B on the GST portal, to ensure you claim only the eligible Input Tax Credit and to spot invoices your suppliers have not filed.

Is this GST reconciliation tool free?
Yes. It is provided free of charge by Kumar Keshav & Co. for clients and visitors.

Is my GST data uploaded anywhere?
No. All matching happens inside your own browser on your device — no invoice data is sent to any server, which keeps your client data confidential.

What is the difference between reconciling with 2A and 2B?
GSTR-2B is a static, month-wise statement used to determine eligible ITC, so Purchase Register ↔ 2B is used for claiming ITC. GSTR-2A is dynamic; comparing 2A ↔ 2B highlights timing and supplier-filing differences.

Can I reconcile more than one month at a time?
Yes — you can reconcile any period from 1 up to 36 months in a single run.
