AI Strategy Transforms AP Automation Platform: 90% Touchless Invoice Processing

Strategic roadmap delivers natural language Copilot, intelligent matching with 250+ patterns, and industry-leading automation rates

ai strategy consulting case study

Executive summary

A leading global Procure-to-Pay (P2P) automation provider serving enterprise clients across energy, renewables, and other industries engaged Zartis to develop a comprehensive AI strategy that would drive product innovation and competitive differentiation.

The problem

With millions of invoices flowing through their platform, the company saw untapped AI potential for intelligent matching, automated coding, and natural language insights. However, internal teams lacked direction on where to invest and how to implement AI capabilities that would deliver measurable ROI.

The solution

Zartis AI consultants conducted strategic assessment workshops to identify high-impact use cases, evaluate technical feasibility, and create a phased implementation roadmap aligned with business priorities.

The outcomes

About the client

The client is an enterprise software provider delivering cloud-based Procure-to-Pay automation solutions that handle eProcurement, invoice processing, vendor management, and payments for hundreds of enterprise customers, processing millions of invoices annually

This client’s platform serves enterprises with complex procurement needs, including energy and renewables clients with IoT-enabled smart metre billing and multi-site organisations requiring centralised AP processing. Whilst their platform already automated significant workflows, manual intervention remained necessary for exception handling, non-PO invoice coding, and complex matching scenarios, creating competitive vulnerability.

The problem

The platform processed massive invoice volumes with sophisticated matching logic, but exceptions and edge cases still required human intervention. Finance teams spent significant time manually resolving PO-to-invoice discrepancies, coding non-PO invoices, and searching historical data.

Why they chose Zartis

Zartis AI

We were brought on to the project for our dual expertise: deep AI technical capability combined with enterprise finance software knowledge. Unlike pure strategy consultancies that deliver decks or offshore teams that lack business context, we could translate AI opportunities into an actionable roadmap their product and engineering teams could actually execute.

how we worked together

The Zartis Approach

6-week engagement structure from discovery to full strategy

Phase 1

Discovery & AS-IS assessment (2 weeks)

We began with deep technical workshops to understand their current matching algorithms, data pipelines, and processing workflows. These sessions ran in parallel with product strategy discussions exploring roadmap priorities and competitive positioning. We conducted customer success interviews to identify pain points directly from their enterprise clients, while simultaneously performing a comprehensive data landscape analysis examining invoice volumes, data quality, current match rates, and exception handling patterns.

Phase 2

Use case prioritisation (2 weeks)

Following discovery, we facilitated cross-functional brainstorming sessions to generate AI opportunities across the platform. Each potential use case underwent rigorous technical feasibility analysis—evaluating data availability, model complexity, and integration requirements—alongside business impact assessment measuring efficiency gains, cost reduction potential, and revenue opportunities. We applied a prioritisation framework that categorized opportunities into Quick Wins (immediate value), Strategic Capabilities (competitive differentiation), and Long-term Bets (future innovation).

Phase 3

Strategy & roadmap edvelopment (2 weeks)

The final phase delivered a comprehensive TO-BE architecture design for their AI-enabled platform, supported by a phased 18-month implementation roadmap. We provided technology stack recommendations covering ML frameworks and serving infrastructure, along with build vs. buy analysis for specific capabilities. The deliverable included detailed resource planning outlining required team composition and skill requirements to execute the transformation successfully.

Our approach

Key strategic decisions

Quick wins built momentum

We identified 3 use cases delivering measurable value in 3-6 months with existing data: Copilot, enhanced matching, and automated coding. This created organisational buy-in before requesting larger investments.

Cloud-based ML platforms and managed services over custom infrastructure accelerated time-to-value, allowing focus on use cases rather than platform engineering.

Workshop-driven approach created shared ownership across departments, eliminating “not invented here” resistance.
Balanced prioritisation framework

Use cases scored across business impact, technical feasibility, and strategic alignment—preventing “shiny object syndrome.”

The AS-IS report identified specific data quality issues, infrastructure gaps, and skill shortages that would block success—addressing these became part of the roadmap.

Phased implementation roadmap and proper resource planning from technological investment to team composition, and skill requirements for full adoption.

the results

From strategy to production:
Real AI capabilities launched

Following the strategic engagement, the client executed the roadmap and delivered measurable AI capabilities:

AI-Powered Copilot

Natural language query interface embedded in the platform, allowing users to interact with invoice data conversationally. Users can identify suppliers with highest volumes, retrieve invoice histories, calculate trends without manual filtering or complex reports.

Impact:

Instant insights, reduced training burden, faster decision-making for AP managers.

Intelligent Smart Matching

AI-powered engine learning from millions of real-world invoices with 250+ unique match patterns, intelligent tolerance logic, and confidence-based matching that routes only true exceptions to humans.

Impact:

Straight-through processing for PO invoices (up from ~70% baseline), reduced manual exception handling, faster month-end close.

38 %

Smart Coding & Routing

AI-driven automation coding non-PO invoices to correct GL accounts and routing to appropriate approvers based on learned patterns, with continuous improvement from user corrections.

Impact:

Faster processing of non-PO invoices, reduced coding errors, PO-level automation extended to historically manual workflows.
