Questions

What is GSTR-2B reconciliation?

It is the comparison of the input tax credit shown in your GSTR-2B with the credit recorded in your purchase books, so that you claim only what the GST portal supports and fix the differences before filing GSTR-3B.

Can I reconcile GSTR-2B with Tally or Busy data?

Yes. Upload the GSTR-2B JSON or Excel from the GST portal and your purchase register as Excel or CSV from Tally, Busy or any other software. Columns are recognised automatically and can be changed.

Does it find mismatches such as a different invoice number or GSTIN typo?

Yes. It matches ignoring slashes, dashes and leading zeros, pairs numbers like VPM/26-27/0045 and 45, spots a GSTIN that differs by one character, tax-head differences, amended documents, duplicates and one invoice split across several entries.

Does it check section 17(5) blocked credit?

It flags entries whose supplier name, ledger or HSN suggests a blocked category and lets you record a decision for each bill or vendor. A flag is a prompt to review, not a finding.

Does it show the section 16(4) deadline and Rule 37 180-day check?

Yes. It lists booked credit not supported by 2B with the last date to claim, and if your books have a payment date it flags invoices unpaid or paid after 180 days.

Does it remember my work after a refresh?

Yes. Auto-save is on by default and keeps your files, column mapping, period and results in your browser for each client. Press Start fresh to clear them, or switch Auto-save off.

Can I send reminders to suppliers whose invoices are missing from GSTR-2B?

Yes. The vendor follow-up tab lists each supplier with the ITC at risk and a ready message you can edit and copy. Follow-up status is saved for the client from month to month.
