SahiGST offers a reconciliation report feature for taxpayers to reconcile their purchase ledger with the current state of GSTR-2A. This report is different from the reconciliation done during filing of GSTR-2. In GSTR-2A, you can see entries that your vendors have "Saved" and thus reconciliation in 2A can begin much before the filing dates of GSTR-2 starts. However you will only take action on various reconciliation items in GSTR-2.
For you to track which of your vendors haven't uploaded invoices yet or have made any errors in their uploads, GSTR-2A reconciliation report is a great tool. This reco can begin as soon as GSTR-1 invoices start getting 'Saved' on GSTN.
For reconciliation within GSTR-2A, you can either prepare your purchase ledger in a very simple format prescribed by SahiGST or a direct export from Tally (ERP 9, 6.1) can be used.
1. Exporting B2B Purchase From Tally For Reconciliation In GSTR-2A
