Reconcile your purchase register against GSTR-2B, free.

What this does and doesn't do

• Both files are read entirely in your browser and never uploaded anywhere.
• It matches on invoice number and GSTIN only. It doesn't check tax rate, place of supply, or whether a mismatch is a genuine timing difference versus a real exposure — that needs the full reconciliation workflow.

How to use this

1. 1

   Export both files as CSV

   Your purchase register from your accounting system, and the GSTR-2B export from the GST portal — both need an invoice number and a GSTIN column.

2. 2

   Upload both

   Order doesn't matter — the tool matches on invoice number and GSTIN once both are loaded.

3. 3

   Start with "missing in 2B"

   These are usually just late vendor filing, but check a few against the vendor's own GSTR-1 history before assuming that for all of them.

4. 4

   Check amount mismatches on matched invoices separately

   These are often a tax-component posting difference, not a real discrepancy — recompute before treating any as an exception.

This free tool, and where it stops

One run, one file, four or five rules — versus every procedure a real engagement needs, run continuously against the full population, with every exception linked to its source document.
