Outsourced Bookkeeping vs In-House Bookkeeper: A True Cost Comparison
When a US small business outgrows doing its own books, the choice usually comes down to two options: hire a bookkeeper or outsource to a bookkeeping firm. Comparing a salary with a monthly fee looks simple, but it misses most of the real cost. Payroll taxes, benefits, software, recruiting, training, supervision and the risk of a single person leaving all belong in the calculation.
This guide sets out a true cost comparison of outsourced bookkeeping vs an in-house bookkeeper, using current US labor data where it exists and a worksheet you can complete with your own numbers.
Is Outsourced Bookkeeping Cheaper Than Hiring a Bookkeeper?
Often, for small businesses that do not need a full-time bookkeeper, because outsourcing replaces salary, benefits, payroll taxes, software, recruiting and training with a single fee for the work actually needed. An in-house bookkeeper can be better value when transaction volume justifies a full-time role or when on-site tasks are essential. The only reliable answer comes from comparing the fully loaded cost of each option for your business.
What an In-House Bookkeeper Really Costs
Salary
According to the US Bureau of Labor Statistics, the median annual wage for bookkeeping, accounting and auditing clerks was 50,670inMay2025(24.36 per hour). Pay varies widely by location, experience and industry, and half of workers earn more than the median.
Benefits and Payroll Taxes
BLS data on employer costs shows that, for private industry workers in June 2026, wages and salaries made up about 70% of total compensation costs and benefits about 30%. Benefits in that measure include employer payroll taxes, insurance, paid leave and retirement contributions. This is an economy-wide average, not specific to bookkeepers or small businesses, but it shows that salary alone understates the cost of an employee.
Other Costs
- Recruiting: job postings, agency fees and management time spent interviewing
- Onboarding and training, including software and your processes
- Accounting software seats, payroll software, hardware and office space
- Supervision and review, often by the owner or an outside CPA
- Cover for vacation, sick leave and turnover
- Year-end CPA fees to correct errors, if the bookkeeper lacks experience
Illustrative In-House Calculation
The figures below combine BLS data with stated assumptions. They are not a quote or a benchmark for your business.
| Cost item | Basis | Annual amount |
|---|---|---|
| Salary | BLS median, May 2025 | $50,670 |
| Benefits and employer payroll taxes | If benefits are 30% of total compensation, total = salary ÷ 0.70 | ≈ $21,716 |
| Total compensation | Salary ÷ 0.70 | ≈ $72,386 |
| Software, hardware and workspace | Your own figure | $_____ |
| Recruiting and training (spread over expected tenure) | Your own figure | $_____ |
| Supervision and CPA review time | Your own figure | $_____ |
| Fully loaded in-house cost | Sum | $_____ |

Calculation: $50,670 ÷ 0.70 = $72,386 (rounded). If you only need part-time help, a part-time employee reduces salary but still involves payroll, recruiting and supervision.
What Outsourced Bookkeeping Costs
Outsourced bookkeeping is usually priced as a fixed monthly fee based on transaction volume, number of accounts, and services included, or occasionally hourly. When comparing quotes, check what is included:
- Transaction categorization and bank and credit card reconciliations
- Accounts payable and receivable management
- Payroll processing or payroll journal entries
- Sales tax tracking or filings
- Monthly financial statements and a review call
- Year-end support for your tax preparer, including 1099 preparation
- Software subscription, if included or extra
- Catch-up or cleanup work, often priced separately
Annual outsourced cost = monthly fee × 12, plus any one-time setup or cleanup, plus software if not included. Compare that number with your fully loaded in-house figure.
Side-by-Side Comparison
| Factor | In-house bookkeeper | Outsourced bookkeeping |
|---|---|---|
| Cost structure | Fixed salary plus benefits and overheads | Fee scaled to the work required |
| Expertise | One person’s skills | A team, often with CPA or senior review |
| Continuity | Risk when the person is away or leaves | Provider covers absences and turnover |
| Availability | On-site during working hours | Scheduled, remote, with agreed response times |
| Control | Direct day-to-day supervision | Managed through scope, deadlines and reports |
| Scalability | Hiring needed to add capacity | Scope adjusted as volume changes |
| On-site tasks | Can handle mail, deposits, filing | Limited to remote work |
| Internal controls | Segregation of duties hard with one person | Provider works separately from those approving payments |

When In-House Makes More Sense
- Transaction volume fills a full-time role year-round
- The job includes on-site duties such as handling cash, mail or inventory counts
- You need someone embedded with operations for quick daily answers
- You already have a controller or CFO to supervise and review the work
When Outsourcing Makes More Sense
- You need less than a full-time bookkeeper’s hours
- You want CPA-level review without a CPA on staff
- Your books are behind and need a cleanup before a routine
- You want continuity regardless of staff turnover
- You want separation between the person recording transactions and the person approving them
Hidden Costs on Both Sides
| In-house hidden costs | Outsourced hidden costs |
|---|---|
| Turnover and re-hiring | Out-of-scope work billed extra |
| Errors found at year-end | Time spent sending documents and answering questions |
| Owner time supervising | Switching costs if the provider is a poor fit |
| Fraud risk with no segregation of duties | Less flexibility for urgent on-site tasks |

A Hybrid Option
Some businesses keep an administrative employee for day-to-day tasks such as collecting receipts and entering bills, and outsource reconciliations, month-end close and financial statements. This keeps local support while adding expert review. As the business grows, a virtual CFO can be added for planning and reporting.
