Case Study: T‑Mobile achieves accurate, mobile retail reporting and near‑real‑time insights with Microsoft Power Apps

T-Mobile adopts Power BI to transform reporting and support retail frontline

T-Mobile, a leading U.S. wireless operator, faced fragmented, Excel-driven reporting that crashed store computers, blocked mobile access, and forced analysts to spend hours reconciling disparate sources. To modernize retail reporting for corporate and third‑party stores, T‑Mobile partnered with Microsoft Power Apps and adopted Microsoft tools including Power BI, Power Automate, Power Apps, Office 365, and Azure SQL to replace fragile workbooks with centralized datasets.

Using Microsoft Power Apps alongside Power BI and Power Automate, the team built mobile-friendly dashboards, row-level security, API-triggered refreshes, and a SQL-backed semantic layer so frontline tablets and analysts work from the same, current data. The solution eliminated duplicate reporting, lifted hundreds of ad‑hoc requests from the analytics team, enabled near‑real‑time workflows, and drove wide adoption—reports now approach one million views per week—while significantly speeding insights and reducing manual data wrangling.
