Reconciliation Control

The process of verifying alignment of records, totals, and business logic across different data systems or layers.

Reconciliation control verifies whether numbers truly align across source systems, warehouses, and reporting layers. Row counts, total amounts, active record counts, and business-rule-based summaries are compared across layers. This process is especially critical in finance, HR, sales, and regulation-sensitive data flows. Dashboards that look visually correct may still be fundamentally wrong if reconciliation has not been performed. For that reason, reconciliation is one of the final trust gates of data quality.
