GSTR-2B against your purchase register
Every purchase invoice matched to what the portal can actually see, so credit is claimed on records that reconcile.
Reconciliation & audit-ready reports
The gap between what your books say and what your returns say is where notices come from. Correct reconciles the two continuously and surfaces the difference while it is still fixable.
Input tax credit is lost on a deadline, not on a decision. An invoice missing from GSTR-2B, a vendor who has not filed their GSTR-1, a mismatch nobody checked — each is recoverable right up until it is not, and none of them announce themselves.

Invoices missing from 2B and vendors who have not filed are flagged while the credit can still be recovered.
Reconciliation runs against live records rather than as a scramble in the days before a return is due.
Export the filings, challans and matching records behind a period, so an audit request is a download rather than a project.
