You are doing the books yourself on Sunday nights, or your part-time person just gave notice, and the quotes you are getting range from $300 a month to $2,800 a month for what sounds like the same work. Somewhere in that spread is the answer to a question nobody has asked you yet: how many hours of bookkeeping does your business actually generate in a month? That number decides whether a fractional bookkeeper is the right hire or a decision you will redo in eight months. Most of the confusion here is a role-clarity problem, not a pricing problem.
The Real Problem: You Are Shopping for a Title, Not a Workload
Owners in this spot usually start by comparing providers. That is the wrong first move. A fractional bookkeeper, an outsourced firm, and a part-time employee are three delivery models for the same underlying work, and which one fits is decided almost entirely by transaction volume, complexity, and how fast you need the month closed.
The second misdiagnosis is more expensive. Owners who feel out of control of their numbers often assume they need more seniority, so they price a controller or a fractional CFO. If your books are behind or your categories are wrong, seniority does not fix that. Somebody still has to reconcile the accounts. Hiring up before the bookkeeping is clean means paying a higher rate for the same catch-up hours.
What a Fractional Bookkeeper Actually Does
A fractional bookkeeper is a bookkeeper you engage for a defined slice of a month rather than as an employee. Ten hours, twenty hours, a fixed monthly scope. The work is the same work a full-time bookkeeper does, sized to what your business actually generates.
The scope in a normal engagement is specific and worth naming, because a vague scope is where these arrangements fail:
- Categorizing transactions on a set cadence, weekly for most businesses over about 300 transactions a month, monthly below that.
- Reconciling every bank, credit card, and loan account to the statement, not to the ending balance the software guesses.
- Accounts payable and receivable upkeep: entering bills, applying payments, keeping the aging reports real.
- Running payroll or coordinating with the payroll provider, if that is in scope.
- Closing the month and producing a P&L and balance sheet on a stated date, usually somewhere between day 10 and day 20.
- Handing clean books to your tax preparer at year end.
Pace matters more than most owners expect. A bookkeeper who touches the file once a month gives you a picture that is five to six weeks stale by the time you read it. A weekly cadence costs more and gives you numbers you can act on. If you are making pricing, hiring, or purchasing decisions off the P&L, buy the cadence, not the lowest monthly price.
What the money actually buys
Bookkeeping pricing tracks transaction volume, number of accounts to reconcile, and close speed. The bands below are typical market ranges for US small businesses, not quotes, and any real number depends on your volume.
| Model | Typical monthly cost | Best fit | Where it breaks |
|---|---|---|---|
| Fractional bookkeeper (contract, part-time) | $400 to $1,500 | $500K to $5M revenue, one to three entities, predictable volume | You need same-day responsiveness or someone in the building |
| Outsourced bookkeeping firm | $500 to $2,500 | Owners who want continuity and coverage rather than one person | You want one named person who learns your business deeply |
| Part-time employee | $1,800 to $3,500 loaded | High transaction volume, daily AP/AR, in-house workflow | Volume does not fill the hours, so you pay for idle time |
| Cleanup specialist (project) | $1,500 to $8,000 one-time | Books are months behind or categories are wrong | It is a project, not ongoing coverage |
| Doing it yourself | Your time | Under roughly 100 transactions a month, single account | Growth, or the first time you need a lender-ready statement |
The practical test is hours. Estimate the monthly transaction count across every account, divide by roughly 100 to 150 transactions per hour for routine categorization, then add reconciliation and close time. Under about 15 hours a month, fractional is almost always the better economics. Above about 30 consistent hours with daily AP and AR, a part-time employee usually wins on cost and responsiveness.
What a Fractional Bookkeeper Does Not Do
This is where the second round of disappointment happens, so it is worth being blunt about the boundary.
A bookkeeper does not file your business tax return. They produce the books the return is built from. Your tax preparer or CPA files it, and the two roles are separate even when one firm sells both.
A bookkeeper does not do tax planning. Deciding on an S-corp election, setting reasonable compensation, or timing equipment purchases for depreciation is CPA or enrolled agent work.
A bookkeeper does not build your forecast or tell you why cash is tight when the P&L says you are profitable. That is controller and CFO territory. If your books are accurate and you still cannot answer where the cash went, the gap is analysis, not data entry, and at that point you have outgrown the bookkeeping question. A bookkeeper who produces accurate statements and no interpretation is doing the job correctly.
A bookkeeper does not clean up a year of unreconciled accounts inside a normal monthly retainer. Cleanup is a separate project with a separate price, and a provider who agrees to absorb it into a $500 monthly fee is either mispricing the work or planning not to do it. Scope and price the cleanup before the ongoing engagement starts, so the monthly fee covers monthly work.
When Not to Hire a Fractional Bookkeeper
Four situations where a different provider fits the same symptom better:
- Your books are more than three months behind. Hire a cleanup bookkeeper or a QuickBooks ProAdvisor for the catch-up project first, then start a monthly engagement on clean books. See what months of behind books actually cost to fix before you sign anything ongoing.
- You have a tax notice with a deadline. Call an enrolled agent or CPA this week. A bookkeeper cannot represent you and the deadline does not move while you onboard one.
- Your books are accurate and you still cannot make decisions from them. That is a controller or CFO question, not a bookkeeping one, and adding bookkeeping hours will not change it.
- You are job-costing construction or project work. Generic bookkeeping will categorize your costs correctly and still leave you unable to tell which jobs made money. That needs someone who sets up job-level tracking from the start.
There is also a volume floor worth naming plainly. Under roughly 100 transactions a month with one bank account and no payroll, most owners are better served by a few hours of setup help and quarterly review than by a monthly retainer.
The Decision Path
Run your situation through these in order and stop at the first one that matches.
- Are the books current? If more than one month is unreconciled, that is a cleanup project first. Everything else waits.
- Is there a deadline from a tax authority, a lender, or a buyer? The deadline sets the provider. A notice means an enrolled agent or CPA; a lender or buyer request means clean historical books on a fixed date.
- How many hours a month does the work actually take? Under 15, go fractional. Fifteen to 30, fractional or an outsourced firm depending on whether you want one person or coverage. Over 30 with daily AP and AR, price a part-time employee.
- Do you need interpretation or just accurate books? If you need someone to explain the numbers and build a forecast, you are looking at a controller, and the bookkeeping should sit underneath that person rather than replace them.
- Sourcing. Once the model is decided, the remaining question is local versus remote versus marketplace, which is a separate decision with its own tradeoffs.
If step one stops you, the underlying issue is not who to hire but what state the file is in. That is the messy-books path, and it has a different sequence.
Frequently Asked Questions
- What is a fractional bookkeeper?
- A bookkeeper engaged for a defined portion of a month rather than as a full-time employee, typically 10 to 20 hours, on a fixed monthly scope. The work is identical to full-time bookkeeping. What differs is that you buy the hours your transaction volume actually generates instead of a 40-hour week.
- How much does a fractional bookkeeper cost?
- Typically $400 to $1,500 a month for a small business, driven by transaction volume, number of accounts to reconcile, and how fast you need the month closed. Weekly categorization costs more than monthly and is worth it if you make decisions off the P&L. Catch-up work on behind books is priced separately, usually $1,500 to $8,000 as a one-time project. These are typical market ranges, not quotes.
- Is a fractional bookkeeper the same as an outsourced bookkeeping firm?
- No. A fractional bookkeeper is one person you engage part-time. An outsourced firm assigns your file to a team, which buys continuity and coverage when someone is out but usually costs a deeper working knowledge of your business. Owners who want one named person who learns their operation choose fractional; owners who want the work to continue regardless of who is available choose the firm.
- Do I need a bookkeeper or a CPA?
- Both, usually, and they do different jobs. The bookkeeper produces accurate books through the year. The CPA or enrolled agent files the return and handles tax planning off those books. If you can only start with one and your books are behind, start with the bookkeeping, because a CPA working from bad records bills you at two to three times the rate to do the same reconstruction.
- When should I upgrade from a bookkeeper to a controller?
- When the books are accurate and you still cannot answer operating questions from them. The usual trigger is somewhere between $2M and $10M in revenue, or the point where you have multiple entities, real inventory, or a lender who wants monthly reporting. The controller question comes after the bookkeeping question, never instead of it.
Next Step
If you are still not sure whether the answer is a fractional bookkeeper, a cleanup project, or a controller, the role clarity diagnostic walks through your volume, your close timing, and what you are actually trying to decide from the numbers, and names the provider type that fits. It takes a few minutes and gives you something specific to price against instead of a spread of quotes for undefined work.
