what kind of checks and balances to you implement to make sure the numbers are accurate, at least the critical ones. Anomalies are easier to spot, but minor but important inaccuracies are tough to identify.

Pick one reported total and trace it back to the source rows with the same date range and filters
For joins check both row count and distinct IDs before and after. A duplicated customer can leave the chart looking normal while quietly inflating every total
