Co-creating Smarter, Scalable Accounts Payable Operations for a Leading Energy Provider

A WNS Perspective

Key Points

  • A leading energy provider faced urgent pressure to exit legacy AP systems while grappling with fragmented tools, manual processes and compliance risks that undermined efficiency and vendor relationships.
  • WNS implemented a low-code, intelligent AP automation platform in just seven weeks – integrating AI-powered optical character recognition, smart workflows and self-service tools into a unified, future-ready ecosystem.
  • The transformation delivered rapid impact, clearing backlogs, improving straight-through processing and establishing a scalable AP foundation to expand automation and support long-term growth.

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.

The Solution
Delivering Intelligent Automation at Speed with TRAC ONE-F

WNS partnered with the client to implement TRAC ONE-F, our proprietary low-code AP Hyperapp, delivering a modern, intelligent invoice processing platform within a 7-week timeline

Working in close collaboration with client IT teams and their third-party consultants, WNS led the end-to-end transformation, from requirement gathering and stakeholder workshops to integration testing and business cutover. The platform consolidated disparate tools into a single intelligent workflow, incorporating:

The Outcome
A Transformed AP Process, from Fragmented to Future-Ready

The implementation of TRAC ONE-F delivered measurable improvements across operational, financial and compliance dimensions. Within just a month of go-live, the client saw marked improvements in efficiency and control, laying the foundation for scalable AP operations.
