Most companies do not have a reporting problem. They have a reconciliation problem. Forty Excel reports usually means forty slightly different versions of the truth, and meetings spent arguing about which one is correct.
A single Power BI dashboard backed by the actual source systems eliminates that argument. Sales, inventory, AR aging, and production all refresh from the same data, on the same schedule, with the same definitions.
The technical work is straightforward. The harder work is agreeing on definitions: what counts as a closed sale, when revenue is recognized, how to handle returns. That conversation alone usually improves the business.
Once the dashboard is live, the old reports quietly die on their own. People stop building them because they no longer need to.
