Outsourced Accounting vs. Hiring In-House: A Cost Breakdown

An in-house accountant costs $55,000 to $75,000 per year in salary alone. Add benefits, software, training, and management overhead, and the true cost is $70,000 to $100,000 or more. Outsourced accounting typically runs $500 to $5,000 per month — $6,000 to $60,000 per year — and includes software, a team of specialists, and the ability to scale up or down as your business changes.

For most small businesses under $5M in revenue, outsourcing saves 30 to 50 percent compared to hiring in-house. Here is how the numbers actually break down.

The real cost of hiring in-house

Most business owners think the cost of an in-house accountant is their salary. It is not. Salary is the starting point, and the true number is 25 to 40 percent higher once you factor in everything else.

Salary

A staff accountant in the United States earns $55,000 to $75,000 per year depending on location, experience, and industry. In higher cost-of-living markets — major metro areas on the coasts — that range stretches to $65,000 to $85,000. A senior accountant or accounting manager costs $75,000 to $100,000 or more. And if you need someone with CPA credentials, expect to pay a premium on top of those ranges.

Benefits and payroll burden

Benefits typically add 25 to 35 percent on top of base salary. For an employee earning $65,000, that means $16,250 to $22,750 in additional cost. This includes:

• Health insurance: $6,000 to $15,000 per year for the employer's share of premiums
• Payroll taxes: 7.65% for the employer's share of FICA (Social Security and Medicare), plus state unemployment taxes
• Retirement contributions: 3 to 6 percent matching if you offer a 401(k)
• PTO and sick days: 15 to 20 days of paid time off means the employee is unavailable for roughly four weeks per year while you continue paying their salary
• Workers' compensation insurance

Software and tools

Your in-house accountant needs software to do their job. That is an additional $2,000 to $5,000 per year in licenses:

• Accounting software (QuickBooks, Xero, or similar): $500 to $2,000 per year
• Payroll platform: $500 to $1,500 per year
• Expense management or bill pay tools: $300 to $1,000 per year
• Spreadsheet and productivity tools: $150 to $400 per year

Training and professional development

Accounting standards change. Software updates. Tax laws shift. Keeping an employee current costs $500 to $2,000 per year in continuing education, conferences, and training time — time during which they are not doing productive work.

Turnover risk

The average cost to replace an employee is 20 to 30 percent of their annual salary. For an accountant earning $65,000, that is $13,000 to $19,500 in recruiting, onboarding, lost productivity, and institutional knowledge walking out the door. And accounting roles have notably high turnover — the profession has been dealing with a talent shortage for years.

Management overhead

Someone has to manage your accountant — review their work, set priorities, handle performance issues, approve time off. If that someone is you, the owner, then the real cost includes your time, which is almost certainly more valuable spent on revenue-generating activities.

The real cost of outsourcing

Outsourced accounting is priced as a monthly fee, and the range depends on the complexity of your business, transaction volume, and the level of service you need.

Monthly fee ranges

• Basic monthly accounting (reconciliation, financial statement prep, accounts payable/receivable): $350 to $1,500 per month
• Mid-tier services (basic accounting plus payroll oversight, reporting dashboards, and regular check-ins): $1,500 to $3,000 per month
• Full-service outsourced accounting with CFO advisory (everything above plus cash flow forecasting, budgeting, strategic planning, and fractional CFO guidance): $2,500 to $5,000+ per month

On an annual basis, that is $6,000 to $60,000 per year — compared to $70,000 to $100,000 or more for a single in-house hire.

What is typically included

Most outsourced accounting providers include the following in their monthly fee:

• Monthly financial statement preparation (profit and loss, balance sheet, cash flow statement)
• Bank and credit card reconciliation
• Accounts payable and receivable management
• Payroll processing or oversight
• Accounting software licenses (QuickBooks, Xero, etc.)
• Regular financial reporting and dashboards
• A dedicated point of contact or team

What you do not pay for

With outsourced accounting, there are no costs for:

• Health insurance, retirement, or payroll taxes
• PTO, sick days, or coverage gaps
• Software licenses (included in your fee)
• Training and continuing education
• Recruiting, onboarding, or turnover
• Office space, equipment, or supplies

Side-by-side comparison

Here is how in-house and outsourced accounting stack up across the factors that matter most:

What you get with outsourced accounting that you don't get in-house

Beyond the cost savings, outsourced accounting gives you structural advantages that a single in-house hire cannot match.

A team instead of a single point of failure

When you hire one accountant, your entire finance function depends on one person. If they quit, get sick, go on leave, or simply make a mistake with no one checking their work, you have a problem. Outsourced accounting gives you a team — multiple people reviewing your financials, providing backup coverage, and catching errors before they become issues.

Broader expertise

A single staff accountant is typically strong in one or two areas. An outsourced team brings specialists in accounts payable, payroll, tax strategy coordination, financial reporting, and CFO-level advisory. You get the benefit of multiple disciplines without hiring multiple people.

Software included

Outsourced providers include the cost of accounting software, payroll platforms, and reporting tools in their monthly fee. They also manage the software — updates, integrations, troubleshooting — so you do not have to.

CFO-level oversight

Many outsourced accounting providers offer fractional CFO services as part of their engagement or as an add-on. That means you get cash flow forecasting, budgeting, financial strategy, and KPI tracking — the kind of work that would require a $150,000+ hire if you wanted it in-house. For a small business, this is often the most valuable piece of the relationship.

Scalability without headcount decisions

As your business grows, your accounting needs grow with it. With an in-house hire, growth means hiring another person — another salary, another benefits package, another desk. With outsourced accounting, you adjust the scope and monthly fee. Scaling up or down is a conversation, not a hiring decision.

When in-house makes sense

Outsourcing is not the right fit for every business. In-house accounting makes more sense when:

• Your business exceeds $5M in revenue and has the transaction volume and complexity to keep a full-time accountant (or a team) busy every day.
• You need someone physically onsite. If your business model requires someone handling cash, processing invoices in person, or managing physical inventory on a daily basis, a remote outsourced team may not be practical for those functions.
• You have complex industry-specific needs that require deep domain expertise embedded in your day-to-day operations — for example, government contracting, manufacturing with complex cost accounting, or multi-entity structures with intercompany transactions.
• You already have the budget for a finance team and want an accounting manager, controller, or CFO as a full-time employee to own the function internally.

Even in these cases, many businesses use a hybrid model — an in-house person for day-to-day operations, with outsourced support for CFO-level strategy, tax coordination, or overflow work during busy periods.

When outsourcing makes sense

Outsourcing is the better choice for most small businesses, and it is especially strong when:

• You are under $5M in revenue and do not have the budget or the workload to justify a full-time hire.
• You do not need someone 40 hours a week. Most small businesses need 10 to 20 hours of accounting work per month, not 160. Outsourcing lets you pay for what you actually use.
• You want to focus on your business, not your financials. If you are the owner and you are spending evenings and weekends reconciling accounts or chasing invoices, outsourcing gives you that time back.
• You are growing and need flexibility. Outsourced accounting scales with you. You do not have to guess whether you need a part-time hire, a full-time hire, or a whole department. You adjust as you go.
• You want CFO-level insight without the CFO-level salary. Fractional CFO services bundled with outsourced accounting give you strategic financial guidance at a fraction of the cost of a full-time CFO.
• You are a practice owner — DPC, concierge, direct specialty care, or functional medicine — and you would rather spend your time with patients than managing an employee who manages your financials.

Nest: $350 per month

Monthly accounting for practices that need clean, accurate financials without the strategic layer. This includes monthly financial statement preparation, bank and credit card reconciliation, and a dedicated team managing your records.

Full-service accounting plus strategic CFO advisory. This includes everything in Nest, plus cash flow forecasting, KPI tracking, budgeting, pricing strategy, compensation planning, and regular strategy calls. You get the financial leadership of a CFO for $6,300 to $19,200 per year — compared to $150,000 or more if you hired one full-time.

Frequently asked questions

Q: How much does outsourced accounting cost per month?

A: Outsourced accounting typically costs between $500 and $5,000 per month, depending on the complexity of your business, transaction volume, and the level of service you need. Basic monthly accounting and reconciliation starts around $350 to $500 per month. Full-service packages that include CFO-level strategy, forecasting, and financial reporting range from $1,500 to $5,000 per month. Most small businesses under $5M in revenue spend $500 to $2,000 per month.

Q: Is outsourced accounting worth it for a small business?

A: For most small businesses under $5M in revenue, outsourced accounting saves 30 to 50 percent compared to hiring in-house. You get a team of specialists instead of one generalist, software and tools are included, and there is no overhead for benefits, PTO, training, or turnover. Outsourcing also gives you access to CFO-level expertise that would cost $150,000 or more to hire full-time.

Q: What is included in outsourced accounting services?

A: Outsourced accounting services typically include monthly financial statement preparation, accounts payable and receivable management, bank and credit card reconciliation, payroll processing or oversight, financial reporting and dashboards, and access to accounting software. Higher-tier packages may also include cash flow forecasting, budgeting, tax strategy coordination, and CFO-level advisory.

Q: How much does it really cost to hire an in-house accountant?

A: The true cost of an in-house accountant goes well beyond salary. A staff accountant earning $55,000 to $75,000 per year will cost $70,000 to $100,000 or more when you factor in benefits (health insurance, retirement contributions, payroll taxes), software licenses ($2,000 to $5,000 per year), training and professional development, PTO and sick days, and management overhead. You also carry the risk and cost of turnover, which averages 20 to 30 percent of annual salary to replace.

Q: When should I hire an in-house accountant instead of outsourcing?

A: Hiring in-house makes sense when your business exceeds $5M in revenue, you have a high volume of daily transactions that require someone onsite, you need industry-specific expertise that is hard to find externally, or you need a full-time finance team member who is embedded in day-to-day operations. For most small businesses below that threshold, outsourcing provides better expertise at a lower total cost.
