Engagement Overview

The client''s backend system of record is SAP. We are seeking a functional expert to study the current billing landscape and deliver a findings report with recommendations for consolidation.

• Final report including risk assessment, effort/cost-benefit view, and a phased roadmap
• Presentation of findings and recommendations to client stakeholders (Finance, IT, and Channel/Operations leadership)
