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 accounts payable automation and unified platforms are
becoming critical to scale operations, reduce costs and strengthen compliance.
The Client Challenge
An Urgent Need for Accounts Payable Transformation 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
accounts payable automation, 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 accounts payable automation.

business expansion – confident in a platform built for adaptability, transparency and automation.
FAQs
1. What is utilization management in the context of energy and utilities, and why
is it important?
In Energy & Utilities, utilization management refers to optimizing how resources, assets, and
operational processes are used to ensure cost efficiency, reliability, and regulatory compliance.
For example, in the case study, the client’s Accounts Payable (AP) processes required
better utilization of financial, operational, and workforce resources. WNS helped streamline and
optimize AP workflows, improving utilization, reducing manual effort, and enabling accurate, timely
payments—critical for operational continuity in the energy sector.
2. How does prior authorization or approval workflows impact suppliers and
internal teams in energy companies?
Prior authorization in energy operations typically includes invoice approvals, vendor validation, and
compliance checks. Inefficient or manual authorization processes delay supplier payments, increase
operational bottlenecks, and reduce financial visibility. In the case study, the energy provider
faced 95%+ manual processing, causing delays and compliance risks. WNS redesigned the AP lifecycle
with automated validation and streamlined approval workflows, significantly improving supplier experience and internal
efficiency.
3. What role does data democratization play in improving financial and operational
decision-making for energy providers?
Data democratization in Energy & Utilities means making financial, operational, and
vendor-related data accessible across departments for faster, smarter decisions. The case study
highlights how limited visibility and siloed data slowed invoice processing and AP efficiency. WNS
implemented a KPI-led governance model, transparent dashboards, and real-time data
accessibility—empowering both finance and operations teams to make informed decisions and
proactively manage exceptions.
4. How can automation and AI transform financial workflows such as Accounts
Payable for energy companies?
Automation and AI reduce manual AP workloads, eliminate errors, standardize complex validation
checks, and accelerate invoice processing. In the case study, WNS introduced intelligent automation, workflow redesign,
and standardized SOPs—cutting manual processing, reducing failure rates, and enabling
scalability. AI-led insights also helped proactively detect duplicate invoices, mismatched records,
and compliance deviations—critical in a tightly regulated utility environment.
5. Why are strong vendor-partner relationships crucial for value-based outcomes in
the energy sector?
In Energy & Utilities, vendor-partner collaboration is essential for uninterrupted operations,
timely procurement, grid maintenance, and compliance-driven projects. Inefficient AP or procurement
processes strain vendor relationships and increase risks. The case study demonstrates how WNS
improved vendor experience through faster processing, error reduction, transparency, and reliable
payment cycles—strengthening long-term partnerships and enabling value-driven, sustainable
operations.
6. How does WNS enable operational resilience for Energy & Utility companies
through digital transformation?
WNS brings deep industry experience, process expertise, and digital-first capabilities to modernize
financial operations like AP, procurement, billing, and customer operations. In the case study, WNS
transformed a fragmented, highly manual AP function into a scalable, automated, KPI-driven
operation—enhancing accuracy, reducing operational risk, and improving business continuity for
the energy provider.
7. What digital capabilities does WNS offer to address challenges such as manual
processing and low visibility in energy operations?
WNS offers AI-driven invoice processing, automated validation engines, workflow management, analytics
dashboards, process re-engineering, and governance frameworks. These solutions eliminate siloed
processes, improve visibility, reduce errors, and allow energy companies to scale operations without
proportional increases in cost or effort—exactly as demonstrated in the AP transformation case
study.
8. Why is WNS a trusted transformation partner for global Energy & Utility
companies?
WNS combines domain expertise, robust digital tools, strong governance, and cross-industry best
practices. Its co-creation approach ensures solutions match unique requirements of utility
clients—whether improving AP, enhancing CX, modernizing billing, or optimizing operational
processes. The case study shows WNS’s ability to deliver measurable impact: standardized
