In-House Hire vs. Outsourced Accounting Firm: The Real Cost

By Kyle Shields, CPA · Acction Advisors · August 25, 2026

Bottom line: A full-time in-house bookkeeper costs $45,000–$60,000+ in salary, and a full-charge accountant $60,000–$90,000+ — plus roughly 20–30% on top for payroll taxes, benefits, and software. Outsourcing the same work to Acction Advisors runs about $6,000–$30,000 a year, usually less than half the loaded cost of one hire, with a full team instead of a single person.

Hiring your first finance or accounting person feels like the responsible move, but the sticker price is only half the story. Here is the honest math on an in-house hire versus outsourcing — and when each one actually makes sense.

The real cost of an in-house hire

Salary is the number you see, but it isn’t the whole story — the total cost runs well above a new hire’s salary. A $55,000 bookkeeper typically costs $68,000–$72,000 once you add the extra employee costs:

Payroll taxes: roughly 8–10% of salary.
Benefits (health, retirement, PTO): often 15–25% more.
Software and tools: $1,000–$3,000/year.
Hiring, onboarding, and management time: real hours, usually yours in a small business.
Turnover risk: when they leave, your books — and institutional knowledge — leave with them, plus recruiting, onboarding, and training costs to replace them.

What outsourcing costs

Outsourced accounting is priced on the work, not a headcount. At Acction, plans start at $500/month, and most small businesses land between $6,000 and $30,000 a year across bookkeeping, accounting, and add-ons — typically well under the total cost of a single full-time hire.

Beyond the dollars

Cost is only the opening argument. The bigger differences:

A team vs. a single point of failure — outsourcing means someone is always covering your books: no sick days, no vacations, no gap when one person quits. You get a whole team for less than one in-house hire.
Breadth of expertise — one hire rarely masters bookkeeping, tax, and CFO strategy; a firm brings all three.
Technology included — you get the software, systems, and processes without buying and maintaining them.
No turnover to manage — continuity is the firm’s job, not your risk.

When an in-house hire genuinely makes sense

In-house is the right call when you need someone physically on-site every day, your volume is high enough to keep a full-timer busy, or your operations are complex enough to warrant dedicated, embedded staff — often past roughly $5M in revenue. A dedicated employee who knows your business intimately is a real asset when you can keep them fully utilized.

When outsourcing wins

For most owner-operated businesses, outsourcing delivers broader expertise, guaranteed coverage, and lower total cost than a single hire. You get a controller’s oversight and a CFO’s perspective without three separate salaries.

Frequently asked questions

Isn’t outsourcing less controlled than having someone in-house?

It is a different kind of control. You trade day-to-day proximity for documented processes, a team that cannot call in sick, and financials delivered on a set schedule. Most owners find they get more reliable output, not less.

What about confidentiality?

A professional firm works under engagement terms and secure systems — at Acction, documents move through TaxDome, our encrypted client portal, not email attachments.

At what size should I bring accounting in-house?

There is no hard line, but many businesses stay outsourced until they are well past $5M in revenue or need daily on-site presence. Until then, a hybrid — an outsourced firm plus a light internal admin — is often the sweet spot.
