The Operational Bottleneck

Reconciling TDS deducted by hundreds of customers against Form 26AS/AIS required cross-matching thousands of ledger rows manually. Rate differences and missing TANs caused massive tax credit lockups.

The Automated Solution

Standardized VBA reconciliation suite with customer ledger auto-split, rate variance flags, unmapped TAN alerts, and CA-ready reconciliation certificates.
