What Is Finance and Accounting Outsourcing (FAO)? A 2026 Guide for CFOs and Founders

FAO gets thrown around in a lot of CFO conversations lately, usually right after someone mentions how hard it’s gotten to hire and keep good accountants. If you’ve heard the term and aren’t entirely sure what it covers or how it’s different from just “outsourcing your books,” you’re not behind. Most of the confusion is legitimate. The industry uses BPO, FAO, offshoring, and outsourcing almost interchangeably, and they aren’t the same thing.

Here’s the plain version. Finance and accounting outsourcing is a structured arrangement where a business hands off specific accounting functions, not the whole finance department, to an external team that operates under agreed standards and reports back on a schedule you set.

Kore BPO builds these teams for US small and mid-sized businesses through our accounting and finance outsourcing services, and we get asked “what is FAO, really?” more often than you’d think, usually by founders who are already outsourcing some version of it without the label. If a contractor closes your books every month or a remote bookkeeper handles your AP, that’s FAO in practice, just without the formal structure around it.

This guide covers what FAO actually includes, how it differs from BPO and offshoring, what it costs in 2026, the signs a business is ready for it, and what to check before signing with any provider.

What FAO Actually Is

Finance and accounting outsourcing is the practice of delegating defined, repeatable finance functions, not strategic decision-making, to a specialized external provider under a service agreement. The provider brings staff, software access, and documented processes. You define the standards, review the output, and keep approval authority over anything that matters.

That distinction matters more than it sounds. FAO doesn’t hand over your financial governance. It changes who executes the work. A CFO or founder still approves payments, sets budgets, and makes the calls that require business judgment. The FAO team runs the repeatable mechanics underneath those decisions: reconciliations, invoice processing, payroll runs, monthly close.

The term gets muddled because vendors label the same service differently depending on who’s selling it. Some call it managed accounting services. Some call it a finance shared-services model. Some just call it “outsourced bookkeeping” and leave it at that. For a founder trying to figure out whether this applies to their business, the label matters less than the structure underneath it: is the work being delivered on a defined schedule, against a defined standard, by a team that isn’t sitting in your office.

Bias disclosed up front, since it matters here. We place offshore finance talent for a living, so we have a stake in you deciding FAO is worth exploring. The market data backs the case up independently, which is why the numbers below come from research firms rather than our own sales pitch.

What FAO Actually Covers

The scope is more specific than “outsource your accounting.” A handful of functions make up nearly all real-world FAO engagements.

• Bookkeeping. Transaction classification, journal entries, reconciliations, and the day-to-day ledger maintenance that keeps your books current.
• Accounts payable (AP). Invoice intake, three-way matching, approval routing, payment scheduling, and vendor record management.
• Accounts receivable (AR). Invoicing, payment collection, cash application, aging reports, and following up on past-due balances.
• Payroll. Salary calculations, tax withholdings, direct deposit administration, and year-end W-2 and 1099 preparation.
• Financial reporting. Monthly close, P&L and balance sheet preparation, and the reporting package leadership actually reviews.
• Tax compliance support. Document preparation and coordination that feeds into your CPA or tax filing process, not the filing itself.

AP and AR together represent the largest share of FAO work industry-wide, largely because they’re high-volume, rules-based, and don’t require someone in the room making judgment calls. Bookkeeping follows close behind. These three functions are the natural starting point for most businesses new to FAO. They’re well-defined and low-risk to hand off, according to Mordor Intelligence’s 2026 FAO market research, which puts the global FAO market near $59 billion this year, growing toward $86 billion by 2031.

FAO vs. BPO vs. Offshoring

These three terms get used as if they mean the same thing. They don’t, and knowing the difference actually helps when you’re evaluating a provider.

The relationship is hierarchical, not overlapping. BPO is the category. FAO is a function within that category. Offshoring, nearshoring, and onshoring describe geography, not service type. You can have FAO delivered onshore, nearshore, or offshore, and you can have BPO cover functions that have nothing to do with finance, like customer support or HR administration.

Where this actually matters, in practice, if a vendor pitches you on “BPO services,” ask what functions and what delivery model specifically. The umbrella term tells you almost nothing about whether they’re a fit for your accounting needs.

Why CFOs and Founders Are Outsourcing Finance in 2026

Three forces are pushing FAO adoption this year, and none of them are new exactly, but they’ve compounded.

The accountant shortage is real and it’s structural. A large wave of accountants has left the US profession over the past several years, and the pipeline replacing them hasn’t kept pace. Most US CFOs now outsource at least some portion of their accounting work, largely because hiring and retaining qualified in-house staff has gotten measurably harder, not because outsourcing suddenly became more attractive on its own.

AI has changed what FAO providers can actually deliver. Robotic process automation used to handle basic data entry. Current AI tooling manages more of the AP/AR workflow directly, flags anomalies that might indicate errors or fraud, and speeds up reconciliation. Deloitte’s 2026 CFO technology guide covers this shift in more depth if you want the full picture.

The decision criteria have shifted from cheapest to most integrated. PwC’s research on CFO priorities for 2026 points to the same pattern we see with our own clients. Finance leaders are less focused on shaving the last few dollars off an hourly rate and more focused on whether a provider’s team, tooling, and reporting actually plug into how their finance function runs day to day.

7 Signs Your Business Is Ready for FAO

Not every business needs this yet, and rushing into it before the underlying problem is clear tends to produce a messy first engagement. So how do you know if you’re actually ready, versus just annoyed with your bookkeeper this particular month? These are the signals worth paying attention to.

The US Chamber of Commerce’s guidance on this lines up with what we see across our own client base. The businesses that benefit most from FAO are the ones where accounting has quietly become a bottleneck, not the ones chasing outsourcing as a trend. If leadership is relying on gut instinct because the numbers arrive too late to be useful, that’s usually the clearest signal.

What FAO Actually Costs

Pricing varies by delivery model, function complexity, and how the contract is structured. A few models dominate the market.

• FTE pricing. A dedicated resource billed at a flat monthly rate, similar to a salary. Offshore FTE pricing typically runs $1,200 to $2,500 per month depending on the country and skill level, compared to $45,000 to $85,000 per year for an equivalent US hire.
• Fixed monthly pricing. A set fee covering a defined scope of work, regardless of transaction volume that month.
• Transaction-based pricing. Billed per invoice, per payroll run, or per reconciliation, common for AP/AR-heavy engagements.

As a rough benchmark, total finance and accounting spend, in-house or outsourced, tends to run 1 to 4% of annual revenue, with smaller businesses at the higher end of that range and larger ones closer to the lower end. Most businesses see a positive return within 3 to 6 months of a well-managed transition, with the first month often costing more than it saves because of setup and parallel-run periods.

Security, Compliance, and What to Vet Before You Sign

Handing off financial data raises the compliance stakes higher than most other outsourced functions. This is the section worth reading slowly before you sign anything.

A few things worth confirming before signing with any FAO provider:

• SOC 2 Type II certification. This assesses whether a provider’s data controls actually held up over a 6 to 12 month period, not just whether they were designed well on paper.
• GAAP familiarity. Confirm the team working on your books understands US GAAP standards and the platforms you already use, whether that’s QuickBooks, Xero, NetSuite, or something else.
• Data handling practices. Ask where data is stored, who has access, and what happens to it if you end the engagement.
• Audit trail and version control. You should be able to trace every change back to who made it and when. If a provider can’t show you this, that’s a real gap.

None of this is meant to scare anyone off FAO. It’s meant to set the standard for what a legitimate provider should be able to show you without hesitation. If a vendor gets vague when you ask about SOC 2 status or data residency, that’s worth treating as a real signal, not a minor detail to sort out later.

FAO is a narrower, more specific idea than the acronym soup around it suggests. You’re not handing off your finance function wholesale. You’re handing off the repeatable mechanics, bookkeeping, AP/AR, payroll, reporting, to a team that executes against your standards while you keep the decisions that actually require your judgment.
