The Industry Landscape
Modernizing AP in Energy with Intelligent Automation
AP operations across the energy sector are often constrained by fragmented systems, high manual effort and legacy infrastructure. As companies navigate complex vendor ecosystems and time-sensitive financial closures, intelligent automation and unified platforms are becoming critical to scale operations, reduce costs and strengthen compliance.
The Client Challenge
An Urgent Need to Modernize AP and Exit Legacy Systems
The client was operating a fragmented and heavily manual AP process spread across five disconnected systems. Only 8 percent of invoices were processed straight-through. The environment relied on aging Optical Character Recognition (OCR) tools, bots, e-mail-based workflows and legacy SAP integrations – creating inefficiencies and backlogs, high processing costs, limited visibility, strained vendor relations and compliance risk.
With a tight Transition Services Agreement (TSA) exit window of just 6-8 weeks and expiring third-party system licenses, the client needed to quickly transition to a unified, future-ready AP platform. The new solution had to ensure business continuity while driving long-term efficiency and automation.
