Top Finance and Accounting Outsourcing Companies Globally

In brief

• Finance outsourcing is becoming more strategic. CFOs increasingly prioritize providers that deliver measurable business outcomes through end-to-end transformation — not just cost savings.
• Nearshoring is accelerating as finance work becomes more complex.
• Leading FAO providers combine strategic advisory, digital enablement, and operational delivery to help finance organizations modernize with greater speed and accountability.
• Independent analyst assessments reveal what differentiates today’s leading F&A outsourcing companies, with AI innovation, finance transformation expertise, location, and flexible operating models as key selection criteria.

Choosing among the top finance and accounting outsourcing companies has become increasingly important as rising cost pressures, talent shortages, and transformation demands prompt CFOs to rethink how work gets done.

As finance organizations take on a broader strategic role, expectations for accounting providers are changing. Today’s buyers are looking beyond traditional labor arbitrage to partners that deliver greater strategic value alongside operational execution.

At the same time, Grant Thornton’s Q2 2026 CFO Survey shows only 42% of CFOs are confident about meeting their cost control goals, and only 48% expect to meet their labor needs. As operational challenges intensify, organizations are increasingly turning to finance and accounting outsourcing (FAO) to improve performance, accelerate modernization, and build more resilient operating models.

Despite rising economic uncertainty, Everest Group projects the global FAO market will expand 6–8% in 2026. Sixty-five percent of finance leaders are currently leveraging offshoring or nearshoring, while only 35% plan to remain fully U.S.-based, the Grant Thornton CFO Survey found.

But with more providers competing than ever before, how do CFOs determine the right finance and accounting outsourcing partner for their business?

Two of the industry’s most respected analyst firms — Everest Group and Information Services Group (ISG) — provide independent assessments that help evaluate the leading F&A outsourcing companies. While each uses a different methodology, both identify the providers best positioned to help finance organizations modernize operations and deliver measurable business outcomes.

Auxis Grant Thornton has been consistently recognized by both analyst firms for capabilities that closely align with today’s evolving FAO demands. This article explores what these reports reveal about today’s FAO landscape, the capabilities distinguishing leading finance and accounting outsourcing companies, and the trends shaping the future of finance outsourcing.

How Everest Group and ISG evaluate the top F&A BPO companies

Independent analyst evaluations are a key resource for finance leaders comparing finance and accounting outsourcing companies because they assess vendors using standardized criteria that extend beyond marketing claims.

The Everest Group Finance and Accounting Outsourcing Services PEAK Matrix® Assessment evaluates providers based on two primary factors that determine market leadership:

• Market success, including client adoption, growth, portfolio strength, and overall market impact
• Delivery capability, including service breadth, innovation, technology investments, delivery footprint, and client satisfaction

In 2025, Everest combined provider submissions with proprietary market intelligence, customer references, transaction data, and independent analyst research to recognize 34 leading global FAO providers.

Everest Group then divides the top finance outsourcing companies into three categories:

The ISG Provider Lens™ Finance and Accounting Outsourcing Services report takes a complementary approach by evaluating providers across individual finance towers including Record-to-Report/R2R, Invoice-to-Pay (I2P), Order-to-Cash (O2C), Tax Services, and Financial Planning & Analysis (FP&A).

Only 25 F&A business process outsourcing companies were selected for each ISG category this year, based on factors including innovation, strategy and vision, digital capabilities, portfolio strength, and competitive positioning. The providers are ranked across four quadrants: Leader, Product Challenger, Market Challenger, and Contender.

Although Everest Group and ISG use different evaluation frameworks, they consistently recognize many of the same global finance and accounting outsourcing companies. Together, their assessments provide finance leaders with a well-rounded view of the market and providers’ strengths.

4 finance and accounting outsourcing trends shaping buyer decisions

Despite their different methodologies, both analyst assessments point to the same conclusion: finance outsourcing is moving beyond transactional processing to become a strategic enabler of future-ready finance operations.

Let’s examine the finance and accounting outsourcing trends shaping buyer decisions in 2026.

1. Strategic outcomes replace cost as the biggest FAO driver

Cost savings remain important, but they are no longer the main differentiator. Only 34% of CFOs now rank cost reduction as the biggest benefit of outsourcing — while 66% prioritize strategic outcomes such as access to talent, AI enablement, and scalability/process standardization, according to Grant Thornton’s Q1 2026 CFO Survey.

Everest Group and ISG highlight how buyers are increasingly prioritizing outsourced accounting partners who can deliver tangible outcomes — combining cost-effective execution with AI and automation, a consultative approach, process optimization, stronger controls, regulatory compliance oversight, and continuous improvement.

Rising outsourcing demand in the midmarket is accelerating this shift. With leaner teams and smaller-scale initiatives, midmarket buyers often require more flexible, collaborative, customized, and end-to-end delivery support than traditional outsourcing models optimized for scale and cost can deliver.

2. AI and automation are becoming core capabilities

With 95% of AI initiatives failing to deliver measurable business impact, organizations are increasingly turning to outsourcing to accelerate transformation. Rather than treating automation as a standalone initiative, leading outsourced finance providers increasingly embed AI, intelligent automation, analytics, and digital workflows to streamline finance and accounting tasks across the enterprise.

Both Everest Group and ISG highlight growing investment in digital capabilities as FAO providers compete to help clients modernize finance while improving AI ROI. Successful AI initiatives demand more than technical excellence — requiring standardized internal processes, trusted data, effective governance, strong risk management, and finance expertise to ensure tangible business value.

3. Nearshoring demand rises to support more complex delivery

As finance outsourcing expands into more judgment-intensive, time-sensitive, and high-touch activities, delivery location has become a strategic consideration. Everest Group’s State of the FAO Market 2025 report points to Latin America as a key driver of future FAO growth — expanding faster than any other region at 10-12%.

Here’s why: Organizations increasingly value providers that combine highly skilled finance and accounting professionals with real-time collaboration, cultural alignment, deep familiarity with U.S. business practices, and time-zone proximity. CFOs ranked the ability to support complex work as their top requirement for choosing an outsourcing location (96%) in Grant Thornton’s Q1 2026 CFO Survey, followed by skilled talent availability (93%).

Everest Group also reports increasing demand for nearshore and onshore delivery driven by compliance requirements, regulatory scrutiny, and the need for closer collaboration on AI-enabled finance and accounting functions.

While offshore delivery remains an important component of global sourcing strategies, CFOs are increasingly adopting hybrid models that leverage offshore locations for high-volume finance and accounting processes while utilizing nearshore teams for complex work that requires closer collaboration.

Sixty-five percent of organizations evaluating Latin America are looking to complement existing operations in Asia or Europe to diversify risk or support more complex process delivery, according to the State of the GBS and Outsourcing Industry in Latin America report by the Shared Services and Outsourcing Network (SSON) and Auxis Grant Thornton.

4. The lines between advisory, technology, and outsourcing are disappearing

The market for outsourced accounting services is becoming increasingly integrated as CFOs seek fewer handoffs and greater accountability across transformation initiatives.

Rather than working with separate advisors, technology implementers, and outsourcing companies, CFOs are increasingly looking for one provider who can design the target state, enable the technology, and manage day-to-day operations with accountability for business outcomes.

These changing priorities are driving a broader evolution of the FAO industry. More accounting firms are acquiring outsourcing providers to complement their advisory strength, while FAO platforms continue to expand consulting and digital transformation services.

The result is a new generation of end-to-end finance transformation providers that eliminate the traditional gap between strategy and execution — helping organizations accelerate modernization while reducing complexity.

What sets Auxis Grant Thornton apart in analyst reports

The value of independent analyst research extends beyond rankings — it identifies the capabilities that differentiate leading finance outsourcing companies. Across both the Everest Group and ISG assessments, Auxis Grant Thornton was recognized for leadership in tech-enabled nearshoring, finance transformation, AI-driven innovation, and a flexible delivery model designed to support both midmarket and enterprise organizations.

That recognition has continued to build across both reports. Auxis Grant Thornton recently celebrated three consecutive years as a Major Contender in Everest Group’s 2025 FAO PEAK Matrix. In 2023, it became the first provider to enter the matrix at the level of Major Contender — adding a Star Performer designation a year later.

ISG honored Auxis Grant Thornton for the second consecutive year in its 2025 FAO Provider Lens. The provider was recognized across all four finance process categories, earning its first Product Challenger designation and the only Rising Star in Order-to-Cash (O2C) — one of the only two stars awarded in the entire report.

Here are Auxis Grant Thornton’s top differentiators according to the analyst reports:

1. One of the only nearshore-first providers among the top F&A outsourcing companies

As finance leaders increasingly prioritize proximity, agility, and real-time collaboration, both Everest Group and ISG identify Auxis Grant Thornton’s nearshore delivery platform as a key differentiator.

While most outsourcing firms have added nearshore locations as a secondary option, Auxis Grant Thornton is one of the only top finance outsourcing companies with leadership and strategy built around a truly nearshore-centric finance outsourcing model.

This matters because nearshore delivery is not simply a location choice — it reflects how providers are structured to support collaboration, business and regulatory alignment, and real-time support for increasingly complex higher-value finance work.

As pioneers of the Latin America outsourcing model, Auxis Grant Thornton’s “high-performing nearshore teams” were recognized as a significant “sweet spot” by ISG, delivering a full suite of P2P, O2C, R2R, FP&A, and industry-specific operations like healthcare revenue cycle management.

Its nearshore platform integrates the strengths of Latin America’s leading shared services destinations, including Costa Rica, Colombia, and Mexico. Services also can expand globally through Grant Thornton’s multinational delivery network across the Americas, Europe, Asia, and the Middle East to support evolving client needs.

2. Finance transformation backed by one of the world’s top accounting firms

Both analyst firms recognize Auxis Grant Thornton’s ability to combine operational delivery with deep finance transformation expertise.

Auxis and Grant Thornton helped lead the broader industry trend toward integrated finance transformation when they joined forces in 2025 — bringing together a leading tech-enabled finance nearshoring platform with the advisory, tax, audit, risk, and finance transformation expertise of one of the world’s top accounting firms.

Everest Group highlights Auxis Grant Thornton’s experience designing finance operating models, shared services, and digital transformation programs as a key strength, while ISG recognizes its consultative approach that drives an end-to-end delivery model. Together, these capabilities enable organizations to move beyond transactional outsourcing toward modern finance and accounting functions.

3. Award-winning AI capabilities and strategic tech partnerships

Digital innovation emerged as another key differentiator across the assessments.

Everest Group highlights Auxis Grant Thornton’s investments in AI, intelligent automation, and intelligent document processing (IDP), supported by strategic partnerships with leading technology providers such as UiPath, OpenAI, Anthropic, Microsoft, Workday, Oracle, and OneStream. ISG similarly recognizes its investments in Agentic AI, automation, and real-time analytics.

But both analyst reports emphasize that technology isn’t enough. Effective financial management also requires standardized processes, trusted data, governance, and finance expertise. Auxis Grant Thornton pairs technical capabilities with deep finance proficiency — helping organizations identify high-value automation opportunities, modernize existing technology environments, strengthen AI readiness and financial reporting, and build scalable operating models that support long-term transformation.

Auxis Grant Thornton further leads with an “Operate to Transform” approach that uses outsourcing efficiencies to help fund modernization, while embedding AI into standardized, well-governed operations tied to measurable outcomes to lower execution risk.

These FAO capabilities are supported by an award-winning AI and automation practice, including recognition as one of the few U.S. providers to earn all three of UiPath’s highest distinctions: Diamond Partner, Agentic Automation Fast Track Partner, and Partner of the Year.

4. Agility for organizations seeking a more flexible delivery model

Another consistent theme in the analyst reports is Auxis Grant Thornton’s ability to adapt its delivery approach to each client’s needs.

While traditional outsourcing models are optimized for large, highly standardized engagements, midmarket organizations often require a different approach — starting with focused initiatives, adapting as priorities evolve, and providing closer collaboration throughout the transformation journey. Everest Group recognizes the provider’s deep experience serving this often-underserved segment, while also tailoring solutions for enterprises that want more flexible delivery models.

Both reports highlight Auxis Grant Thornton’s consultative approach, agility, collaboration, and ability to tailor solutions by industry, operating model, and strategic priorities as key strengths. Everest also cites high client satisfaction with complementary services such as IT migration and management, reinforcing the provider’s ability to deliver comprehensive transformation support.

The analyst firms further recognize the provider’s industry expertise across multiple sectors, including healthcare, retail, consumer packaged goods (CPG), manufacturing, finance and accounting services, real estate, hospitality, and private equity-backed organizations. By combining industry specialization with tailored delivery, Auxis Grant Thornton brings relevant benchmarks and proven best practices that accelerate value while maintaining regulatory compliance and managing risk.

Choosing the right FAO partner for your business

Independent analyst assessments make one thing clear: choosing among finance and accounting outsourcing companies is no longer simply a question of cost or scale.

Organizations should evaluate providers based on their location, ability to drive modernization, agility, technology maturity, operational flexibility, industry expertise, and whether the delivery model is aligned to their organization’s size, complexity, and long-term goals.

Auxis Grant Thornton’s recognition by both Everest Group and ISG reflects these evolving market priorities and reinforces its ability to help organizations modernize finance while improving agility, resilience, and long-term business performance.
