ISG Provider Lens™ Finance and Accounting Outsourcing (FAO) Services - Order to Cash (O2C) - Global 2025

F&A outsourcing — From innovation to execution, driving unified and autonomous finance

The Finance and Accounting Outsourcing (FAO) market in 2025 is undergoing one of the most significant shifts it has seen in the past decade. In contrast to 2024, when discussions surrounding AI, generative AI (GenAI) and advanced analytics primarily focused on pilots and early-stage PoCs, the current landscape is defined by operationalized innovation. Providers have transitioned from experimentation to deployment, embedding these technologies into live delivery environments and demonstrating measurable business impact.

This evolution is not simply about technology adoption; it reflects a broader repositioning of FAO from a cost-saving lever to a strategic enabler of future-ready finance operations. The narrative has shifted from focusing on cost arbitrage toward delivering autonomous finance, an end-state where human effort is minimized in routine processes. In this environment, intelligent systems orchestrate workflows, and finance talent is redeployed to high-value analysis and decision-making.

From cost arbitrage to strategic partnership

FAO providers are increasingly positioning themselves as strategic partners to CFOs, a role that extends beyond operational efficiency to include digital finance strategy, enterprise risk management, compliance oversight and value creation. This positioning reflects the market’s evolution toward advisory-led models, where transformation is seen as
the starting point rather than an add-on. Providers are engaging earlier in the finance transformation journey, shaping operating models, recommending technology stacks and designing governance frameworks before taking on managed services delivery.

A key dimension of this transformation is the integration of consulting with operations. Leading providers are building seamless engagement models that follow a sequence of design thinking, process consulting and managed services. For larger players, this involves leveraging consulting insights to feed into outsourcing contracts. For smaller, more agile players, differentiation comes from flexible transformation frameworks that can be deployed without the complexities of largescale global engagements.

GCC partnerships and co-sourcing models

Global Capability Centers (GCCs) remain integral to enterprise finance operations, but their role is evolving. Many large enterprises are rebalancing work between GCCs and third-party FAO providers, leading to ecosystem-based co-sourcing models. In these arrangements, GCCs retain certain core or strategic functions, while providers manage
specialized processes, transformation initiatives and scalability requirements. This flexible distribution of work enables enterprises to optimize cost, ensure compliance and enhance agility, while tapping into the provider’s domain expertise and technological capabilities.

FAO providers are also increasingly advising on GCC transformation, helping organizations redesign their operating
models, optimize existing GCC performance or transition select processes from GCCs to outsourced delivery. This advisory-led co-sourcing model is becoming a prominent engagement type in 2025, reflecting the market’s shift toward integrated, ecosystembased finance operations.

Digital-first and AI-led transformation

Digital-first strategies have moved from aspiration to standard practice in FAO. Providers are deploying orchestration
platforms that integrate AI, automation, analytics and workflow management into unified, cloud-native environments. These platforms are often built in collaboration with ERP vendors, hyperscalers and specialist finance software  providers. Where 2024 was characterized by isolated automation and experimentation, 2025 marks a significant
maturity leap:

• AI and GenAI are now embedded in live delivery models for use cases such as anomaly detection, reconciliations,
automated financial commentary, predictive cash flow forecasting and tax document interpretation.

• GenAI applications are no longer standalone pilots; they are linked to process orchestration layers, enabling AI
insights to trigger downstream actions without manual intervention.

• Predictive analytics is being widely deployed for working capital optimization, demand forecasting and exception management.

Agentic AI, the newest entrant in the FAO technology mix, represents a significant advancement toward autonomous operations. These systems can execute multistep workflows autonomously by reasoning over data, making process-level decisions within predefined guardrails and initiating actions without human triggers. In the context of FAO, early production deployments include:

• End-to-end cash application, where the AI not only applies payments but also resolves exceptions and  communicates status updates to clients.

• Tax compliance orchestration, where jurisdiction-specific rules are applied automatically, filings are validated and submissions are made without human intervention.

• Close and consolidation sequencing, where tasks are prioritized and executed autonomously, with anomalies escalated for human review only when necessary.

However, the commercial model for agentic AI remains a gray area. Providers are still determining how to monetize these capabilities, balance risk-reward sharing with clients and align pricing with tangible business outcomes. Currently, contracts either integrate agentic AI into existing delivery models or pilot separate pricing mechanisms, but a marketwide commercial standard has yet to be established.

Industry-specific platforms and preconfigured AI models

Industry specialization has long been a differentiator, but in 2025, it is defined by platform-led, preconfigured  analytics and AI models that accelerate time to value. Providers are delivering vertical-specific solutions for industries such as BFSI, healthcare, manufacturing and chemical.

These prebuilt models incorporate industry regulations, compliance frameworks and performance benchmarks directly into delivery workflows, reducing the need for lengthy customization and increasing adoption speed.

Outcome-based engagement models

Commercial models are also evolving. Outcome-based contracts are now common in mature process areas such as invoice to pay (I2P), order to cash (O2C) and statutory reporting, tying provider compensation to metrics such as days sales outstanding (DSO) reduction, working capital improvement, forecast accuracy and tax return error rates.

Some providers are experimenting with contracts where 70 to 100 percent of fees are outcome-linked. This approach reinforces shared accountability for results and incentivizes continuous improvement rather than volume-based delivery.

FP&A, R2R and tax growth

Among the finance towers, strategic finance verticals are the fastest-growing segments, driven by finance  modernization, scenario planning and rolling forecasts. Analytics-led working capital optimization is a particularly high-demand area, with providers offering predictive models that link payment terms, supplier behavior and collections performance to cash flow forecasts.

R2R continues to expand, now incorporating tax, compliance, ESG reporting and narrative insights. This evolution reflects the expanded role of the CFO’s office, where financial reporting is integrated with regulatory disclosures and sustainability metrics.

Tax services have shifted from being a niche outsourcing area to a mainstream FAO offering. Providers are now  delivering end-to-end tax compliance, transfer pricing, indirect tax automation and tax advisory services aligned with corporate strategy. While ESG reporting remains predominantly regulation-driven, it is being built into close cycles, particularly in regions with mandatory sustainability reporting requirements.

Innovation versus execution

One of the most significant shifts from 2024 is that innovation is no longer the differentiator in FAO; execution has taken its place. Enterprises are less interested in hearing about pilots and more focused on proof of AI-driven productivity gains, measurable KPI impact and sustainable performance improvements. This change has redefined competitive advantage—success is now measured by the ability to demonstrate outcomes, scale them across client portfolios and integrate them into cross-tower delivery.

Integration across towers — Unified Finance Operations

The ability to integrate processes across finance towers within a single, unified delivery ecosystem is becoming a central value proposition for providers. They are investing in platforms and governance models that consolidate data, processes and analytics into a cohesive environment. For existing clients, this Unified Finance Operations approach unlocks efficiency, eliminates redundant workflows and enables cross-functional insights. This integration is  particularly valuable when linking upstream procurement data to downstream payment cycles or combining sales order data with cash collection analytics.

Talent model evolution

As technology takes over transactional execution, the talent profile in FAO is shifting. The new priority is finance professionals with high data literacy, analytics expertise and a strong technology quotient who can partner effectively with AI systems, interpret advanced models and orchestrate transformation initiatives. To meet this demand,  providers are upskilling existing teams, hiring hybrid financetechnology profiles and embedding data scientists within delivery teams.

Summary

In 2025, the FAO market finds itself at a maturity crossroads:

• AI and GenAI have moved beyond pilots into scaled, operational use, delivering measurable business value

• Agentic AI is emerging with promising early deployments, although a defined commercial playbook remains elusive

• Industry-specific AI models and vertical platforms are accelerating adoption and differentiation

• Outcome-based models are reshaping commercial structures to align with client business objectives

• GCC co-sourcing is creating flexible, ecosystem-based delivery models

• Execution excellence and cross-tower integration have replaced innovation theater as the true market differentiators

Providers that can combine execution strength with strategic advisory services, preconfigured industry AI and  integrated delivery will define the next chapter of FAO. In this evolving landscape, autonomous, insightdriven finance operations will become the standard, solidifying the provider’s role as a strategic partner to the CFO.
