Mitsui Coal Holdings manages a 40-million-ton annual coal portfolio across Australian mines. Legacy finance tools created data silos and slow consolidation. After deploying SAP S/4HANA and SAP Business Planning and Consolidation on AWS via PwC, the company gained real-time analytics, eliminated spreadsheet-based planning, and cut month-end data processing from two days to 30 minutes.
