Introduction
Accounting teams rarely run out of things to do. The books have to be maintained, invoices processed, accounts reconciled, payroll completed, and financial reports prepared, often on a tight monthly cycle. For many accounting teams, these recurring responsibilities can consume a substantial share of the time that experienced accountants could otherwise devote to analysis and decision support.
That is where outsourcing can change the equation. When a separate team handles routine accounting work, in-house accountants can spend more time on analysis, planning, and decisions that require their judgment.
But what does that actually look like?
The answer is more specific than the usual promise of “higher-value work.” Across the accounting profession, client advisory services are expanding around activities such as financial analysis, forecasting, cash-flow planning, performance measurement, and CFO-level business insights. The shift is not automatic, and outsourcing alone does not make an accounting function more strategic. But it can create room for accountants to use their expertise differently.
What Work Moves Out?
A useful starting point is the work that sits at the transactional end of accounting.
This 2024 Client Advisory Services Benchmark Survey covers firms offering services ranging from transactional accounting and bookkeeping through higher-level advisory work. The survey reflects how accounting firms are building broader service models rather than limiting their role to producing financial records.
That transactional work includes activities such as bookkeeping, accounts payable and receivable, payroll, reconciliations, financial reporting, and other recurring accounting processes.
These activities are essential. They keep the books accurate and the business operating. But many are repetitive and process-driven, making them suitable for standardization, technology, outsourcing, or a combination of the three.
That distinction is important. Outsourcing does not mean the work has become unimportant. It means the work may no longer need to consume as much time from an organization’s most experienced accounting professionals.
So What Do Accountants Do Instead?
This is where the conversation gets more interesting.
One increasingly important destination is client advisory services, or CAS.
CPA.com and the AICPA describe CAS as a spectrum that extends from transactional accounting and bookkeeping to higher-level business insights. At the more advanced end, accountants move beyond producing financial information and help clients understand what that information means for the business.
That can mean analyzing cash flow, developing forecasts, tracking performance indicators, evaluating business scenarios, or helping management understand the financial consequences of a decision. The questions change.
Instead of only asking, “Are the accounts reconciled?” an accountant may be asking, “Why is cash flow deteriorating?” Instead of simply preparing a monthly report, the accountant may explain what caused the change in margins. Instead of recording historical results, the accountant may model what happens if sales increase, collections slow, or the company adds employees.
The underlying accounting knowledge is still essential. What changes is how that knowledge is applied.
The Growth of CAS Is Real
This movement toward advisory work is not simply a marketing trend.
This survey, based on 206 U.S. CAS practices and 2023 financial data, reported 17% median growth in CAS practices. Firms projected median growth of 15% for the following year and 99% median projected growth over three years. Median net client fees per professional reached $156,250, a 29% increase from the previous survey.
The survey also found that firms generating significant revenue from CFO or higher-level business-insights advisory services had more than 30% higher monthly recurring revenue. Nearly four-fifths of participating practices had dedicated CAS staff, while 51% reported continuing to invest in technology.
These numbers do not establish that outsourcing caused CAS to grow. The survey was designed to benchmark CAS practices, not to prove a causal relationship between outsourcing and advisory growth. What they do show is that accounting firms are investing in and building substantial service lines around work that goes beyond transaction processing.
What Does the Shift Look Like in Practice?
Recent examples from the profession make the change easier to see.
Journal of Accountancy reported in 2025 on CRC, a Missouri firm that had historically been heavily focused on tax-return compliance. New leadership moved the firm toward a year-round CAS model built around more personalized advisory services. The same article showed how it was possible to reshape a client base and service model as part of its move toward CAS.
These examples point to an important reality: firms do not create advisory capacity simply by removing routine work. They have to decide what they want their accountants to do next.
That may involve developing forecasting services, building financial models, providing management reporting, supporting cash-flow planning, or having accountants work more directly with clients on business decisions.
The same journal’s coverage of CAS similarly describes services ranging from bookkeeping and financial reporting to payroll management and automation support, through to CFO-level services such as cash-flow forecasting and tax planning.
Both areas of work are essential to the accounting function, but they require different levels of professional judgment and business interpretation.
Technology Is Part of the Same Shift
Outsourcing is also increasingly intertwined with automation.
A 2025 analysis of intelligent process automation identified data entry, reconciliations, and compliance documentation as examples of repetitive activities that can be automated. The article notes that reducing the time spent on these activities can free CPAs to focus on analysis, strategic recommendations, and client advisory services, while still retaining appropriate oversight.
That makes outsourcing and automation less like competing choices and more like different ways of addressing the same capacity problem.
Some work can be standardized and handled through technology. Some can be performed by a specialized accounting team. And some work still requires an accountant’s judgment, context, and ability to communicate with management.
The opportunity is to use each where it makes the most sense.
The Part That Often Gets Missed
There is a tendency to present the process as simple:
Outsource the routine work → free up accountants → get more strategic work.
In practice, the middle step is not enough.
If a firm removes 20 hours of repetitive work from an accountant’s week but does not redesign the role, those 20 hours can easily be filled with more administrative work or more of the same type of accounting.
Current CAS research points to the importance of deliberate strategy, staffing, technology, and standardized processes. The 2024 CAS Benchmark Survey found that practices with a formal CAS business plan reported higher median annual client revenue, while firms that continually invested in technology reported higher revenue and served more clients.
Journal of Accountancy’s reporting reaches a similar conclusion: firms moving into CAS need to think carefully about their target clients, service offerings, people, processes, and technology.
In other words, freed capacity is only the starting point.
The Bottom Line
The idea that outsourcing frees accountants for “higher-value work” is too vague to be particularly useful.
A more accurate description is this:
Routine accounting work—bookkeeping, payables and receivables, payroll, reconciliations, and recurring reporting—can increasingly be standardized, automated, or handled by specialized teams. That creates an opportunity for accountants to spend more time on forecasting, cash-flow analysis, performance measurement, scenario planning, and business advisory.
The evidence shows that firms are investing heavily in these advisory capabilities, and CAS has become a significant and growing part of the accounting profession. But outsourcing does not automatically produce that outcome. Outsourcing creates capacity. The real value comes from deciding what to do with it.
For accounting leaders, the more useful question may not be, “What work can we outsource?” but “What work should our accountants be doing once they no longer have to spend as much time on the routine?”
