The Four Drivers of Bookkeeping Cost

Transaction volume is the biggest driver of bookkeeping cost. A business with 80 transactions a month is a fundamentally smaller job than one with 800, regardless of revenue.
Account count matters next: every bank account, credit card, loan, and payment processor is another monthly reconciliation. Five accounts close faster than fifteen.
Entity count multiplies everything. Two LLCs and a holding company means three sets of books plus intercompany entries, not one set that is three times larger.
Cleanup state sets the starting price. Books that are months behind, or reconciled to nothing, need a catch-up project before a monthly service can even begin.
Complexity add-ons stack on top: inventory, payroll, accrual accounting, AR and AP management, and industry rules like job costing or revenue recognition.

Market Ranges: What Businesses Actually Pay

Software alone (QuickBooks, Xero, Zoho Books) runs tens of dollars per month, but software is a ledger, not a bookkeeper. Someone still has to do the work.
Freelance bookkeepers commonly charge a few hundred dollars a month for a simple, low-volume, single-entity business, with hourly rates roughly in the $30 to $90 range.
Professional firms serving businesses in the $1M to $20M revenue range typically land somewhere between several hundred and a few thousand dollars per month, scaling with the drivers above.
Accrual books, multiple entities, and controller-level review push toward the top of that range; cash-basis books with low volume sit near the bottom.
Treat any quote far below market with suspicion. The most expensive bookkeeping is cheap bookkeeping that has to be redone at cleanup rates before a loan, a sale, or a tax filing.

In-House vs Outsourced: The Real Math

A full-time in-house bookkeeper costs a salary plus roughly 20 to 30 percent more in payroll taxes, benefits, software, and management time. All-in, that is a meaningful multiple of most outsourced engagements.
The in-house hire also concentrates risk: one person's vacation, resignation, or blind spots become your close calendar's problem, with no reviewer behind them.
Outsourced bookkeeping buys a fraction of a team instead of all of one person: preparer plus reviewer, coverage through turnover, and capacity that flexes with volume.
In-house starts to win when daily transaction volume is genuinely full-time work, such as heavy AR and AP operations, or when you need someone physically present.
Many businesses in the middle run a hybrid: an office manager handles bills and invoicing daily, and an outside firm owns reconciliations, the close, and the financials.

When the Cost Goes Up, and Should

Growth raises volume, and volume raises price. Expect the fee to step up as transactions, accounts, headcount, and locations climb, not stay flat forever.
Moving from cash to accrual accounting adds real monthly work: deferrals, accruals, and schedules that cash-basis books never carry. Lenders and buyers usually force this step.
Adding payroll, inventory, or a second entity are the classic step-changes. Each adds a workstream, not just a few transactions.
Catch-up and cleanup projects price separately from monthly service, usually quoted per month of backlog after a diagnostic look at the books.
A fee that never changes while the business doubles is its own red flag: either the scope quietly shrank or the quality did.

Fixed-Fee vs Hourly Billing

Hourly billing shifts all the risk to you: a slow month costs less, but a messy month, a software migration, or an inexperienced bookkeeper costs more, and you find out after the fact.
Fixed monthly pricing makes the cost predictable and puts the efficiency incentive on the firm. Most modern bookkeeping services have moved this direction.
Fixed-fee only works with a written scope: which accounts are reconciled, what reports are delivered, by what day of the month, and what triggers a price review.
Hourly still makes sense for genuinely unpredictable work: one-time cleanups, migrations, or exploratory projects where nobody can scope the mess in advance.
Whichever model you choose, ask how much does bookkeeping cost at the next stage of your growth, so the step-ups are agreed before they happen.

Buying Bookkeeping Well

Compare quotes on scope, not price. A cheap quote that excludes reconciliations, accrual entries, or a delivery date is not comparable to one that includes them.
Ask who does the work and who reviews it. A preparer-plus-reviewer structure catches the errors a solo bookkeeper ships.
Insist on a monthly delivery date for financials. Books delivered six weeks late are accurate history, not a management tool.
