In-House vs Outsourced Bookkeeping Costs: A Comparison Guide for SMBs

When small and medium businesses look at professional bookkeeping options, the first question is almost always about the cost. The salary of a full-time bookkeeper tends to look straightforward on paper, but the real total cost runs higher once everything is added up. Outsourced bookkeeping services present a different structure, usually with lower overall spend for most companies under a certain size. Here’s a practical side-by-side look based on current market ranges.

What an in-house bookkeeper actually costs

A full-time bookkeeper in the United States typically earns an average base salary between $42,000 and $58,000 a year, with medians often landing around $45,000 to $51,000 – depending on their location and experience. However, that figure alone is only the starting point.

 

Adding in employer payroll taxes (around 7.65% for FICA plus state unemployment), health insurance contributions (often $7,000 to $15,000 or more), paid time off, retirement matching if offered, and the total climbs quickly. Software licenses for software like QuickBooks or similar tools, computer equipment, and a share of office space or remote setup costs add a few thousand more. Recruiting and onboarding can run $5,000 to $14,000 the first year, and there’s always the risk of turnover that forces the process to restart.

 

Most calculations put the fully loaded annual cost for one full-time in-house bookkeeper in the $65,000 to $95,000 range, with some estimates reaching higher once management time spent reviewing work or covering gaps is factored in. Part-time arrangements (factor ~20 hours a week) can bring the total down to roughly $28,000 to $50,000 a year, but they often come with the same recruitment headaches and limited capacity during busy periods.

What outsourced bookkeeping typically costs

Outsourced bookkeeping services are usually priced monthly based on transaction volume, number of accounts, and the depth of reporting needed. For a micro or sole-proprietor business with under 50 to 100 transactions a month, fees often start at $200 to $500. Small businesses with 50 to 300 transactions commonly pay $400 to $1,500 per month. Growing or more complex operations (inventory, multi-entity, payroll, higher volume) can land between $1,200 and $2,500 or more.

 

That works out to annual costs in the $6,000 to $30,000 range for most SMBs needing solid monthly bookkeeping, reconciliations, and basic financial statements. Some plans include software access or integration, review by a more senior person, and backup coverage when the main contact is unavailable. Setup or cleanup fees for messy books can appear as a one-time charge, but ongoing fees stay predictable.

Direct comparison

For a typical small business needing full-cycle monthly bookkeeping services:

 

• Full-time in-house: $65,000–$95,000+ per year
• Part-time in-house: $28,000–$50,000 per year
• Outsourced (domestic or virtual firm): $6,000–$24,000 per year for comparable scope

Savings of 50 to 80 percent versus a full-time hire are common once benefits, software, recruiting, and downtime are included. An outsourced plan at $800 to $1,500 a month often delivers similar or better coverage than one internal person, plus built-in review and continuity if someone is out sick or leaves.

 

The gap often narrows for larger or highly complex operations. Businesses with very high monthly or quarterly transaction volumes, daily operational needs that require someone on-site, or revenue well into the multi-million range sometimes find a hybrid model (junior in-house support plus outsourced oversight) or a full internal hire makes more sense. For the majority of SMBs processing a few hundred transactions a month or less, the numbers favor outsourcing their bookkeeping work on pure cost.

Other cost factors worth weighing

In-house staff create fixed costs that continue whether the business is busy or slow. Outsourcing it scales more easily, where you can bump up the plan during peak seasons and scale back later without severance or new hiring cycles. Error rates and cleanup work also matter. Messy books can lead to extra CPA fees or tax penalties that quietly increase the true cost of either approach, but professional accounting firms will often catch issues earlier through standardized processes.

 

Location plays a key role in all of this too. Salaries and benefits run higher in major coastal cities like NYC, SF, LA, and Miami, which widens the advantage of outsourcing. Offshore or nearshore options for bookkeepers can push fees even lower, however many businesses prefer domestic providers for easier communication and stronger familiarity with U.S. tax codes, compliance, and reporting rules.

Making the right call

Run the numbers for your own unique situation. List out your current transaction volume, the reports you actually need on hand each month, and any specialized requirements like inventory tracking or multi-state sales tax regulations. Then request some quotes that match that scope and compare them against the fully loaded cost of an equivalent internal role. For most smaller companies, the outsourced bookkeeping route delivers the same (or better) results at a lower total cost while freeing owners from the ongoing responsibilities of managing an employee.
