Twobmatch: frequently asked questions

Yes. Paste your purchase register and the GSTR-2B B2B sheet, click Reconcile and you get the full result, the CSV report and supplier emails. There's no sign-up and no limit. It runs in your browser, so nothing is uploaded.

The full Twobmatch, launching within 60 days: upload the GSTR-2B Excel or JSON straight from the portal, keep unmatched invoices pending from month to month until they show up, manage many GSTINs (for CAs and multi-state businesses) and schedule reminders to suppliers. The founding price is ₹299 / $7 a month, paid now as your first month and fully refundable any time before launch. Or join the free waitlist.

On the GST portal go to Returns Dashboard, choose the period, open GSTR-2B and download the Excel. Open the B2B sheet, select from the header rows down to the last invoice, copy and paste it into the GSTR-2B box. Headers like 'GSTIN of supplier', 'Invoice number', 'Taxable Value' and 'Integrated / Central / State Tax' are recognised automatically. You can also save the sheet as CSV and upload it.

Any export with a header row and columns for supplier GSTIN, invoice number, invoice date, taxable value, IGST, CGST and SGST (a 'total tax' column works too). Tally, Zoho Books, Busy and Excel registers all work after copy-paste. Without a header row, use the order GSTIN, invoice no, date, taxable, IGST, CGST, SGST.

In steps: exact supplier GSTIN and invoice number; then the number with symbols, financial-year tags (2025-26, 25-26), prefixes like INV and leading zeros removed; then the digits only; then the same PAN under another GSTIN; and last, the same supplier with the same taxable value and tax. Every non-exact match is labelled so you can check it.

Don't claim ITC on them in GSTR-3B yet (Section 16(2)(aa) and Rule 36(4)). Ask the supplier to report them in GSTR-1 / IFF; the tool writes that email. Check again next month. Credit for a financial year must be claimed by 30 November of the next year or the annual return date, whichever is earlier.

Either you haven't recorded a genuine purchase (record it and claim the credit) or the invoice isn't yours or is wrong. In that case reject it in the Invoice Management System (IMS) before filing GSTR-3B, so it doesn't count in your 2B.

The free check matches B2B invoices and debit / credit notes that you paste (negative values are handled). Imports (IMPG), ISD credit and reverse charge entries are best checked separately for now; the full version will cover all GSTR-2B sections.

No. It does the matching and gives you the lists. Decisions on eligibility, blocked credit under Section 17(5), reversals and anything going into a reply to a notice should be checked by your CA or tax practitioner.
