GSTR-1 · Books vs Portal Matcher
- Match key is GSTIN + Invoice/Note Number — Books and Portal files must be exports of the same GST category structure (
b2b,sez,de / cdnr / cdnur / exp), or matching will be inaccurate. - Rate-split invoices are matched line-by-line — if an invoice has multiple tax-rate lines (e.g. 5% and 18%), each rate-line is matched and compared independently, so you can see exactly which specific line differs instead of just an invoice-level total.
- Always independently verify results before relying on them for return filing, reconciliation sign-off, or any statutory purpose — see the Disclaimer below.

What Is GSTR-1 Reconciliation?
GSTR-1 reconciliation is the process of comparing the outward supply details reported or prepared for GSTR-1 with the sales invoices and transaction records maintained in your books of accounts.
Differences can arise due to missing invoices, incorrect invoice numbers, differences in taxable values, GST rate variations, tax amount mismatches, credit notes, debit notes, or transactions recorded in different reporting periods.
Reconciling these records helps identify discrepancies that may require correction or further verification before filing or finalizing GST returns.
