How this check works
What it compares
Supplier GSTIN and invoice number in GSTR-2B against the same in your purchase register, then the tax on each invoice. Invoice numbers are compared without spaces, slashes or leading zeros, so SLT/2601 and slt 2601 match.
The five results
Matched; Amount differs; Possible match (same supplier and amount, number written differently); In GSTR-2B, not in your books (credit available but not booked); In your books, not in GSTR-2B (credit at risk until the supplier files).
Why it matters
Input tax credit can be taken only for invoices that appear in GSTR-2B (section 16(2)(aa) of the CGST Act and rule 36(4)). Checking every month keeps the credit you claim in GSTR-3B safe.
Files it reads
The GSTR-2B Excel or JSON downloaded from the GST portal, and an Excel or CSV export of your purchase register from Tally, Zoho, Busy or any other software. The columns are recognised automatically and you can change them.
Indicative, not professional advice. It uses only what you enter.
