$300 a month or $2,000 a month, and most owners genuinely have no idea why the two services are priced differently. Sometimes the lower-priced one is perfectly fine. Sometimes it is missing half of what you actually need. The difference almost never shows up until you are staring at a surprise tax bill or a lender asking for three years of clean financials.

This piece breaks down what you are actually paying for at different price points, how outsourced bookkeeping compares to hiring in-house, and who this kind of service is not right for.

What Does Outsourced Bookkeeping Cost in 2026?

For most small service businesses, the range runs from $750 to $1,500 per month when the package includes real monthly accounting, tax filings, and at least some review of the numbers. Below that range, something is usually missing. Above $2,000, you are typically dealing with a more complex operation: multiple entities, high payroll headcount, or a business where the advisory work takes significant time each month.

Here is how the market generally breaks down as of 2026:

$300 to $600 per month covers transaction reconciliation for businesses with relatively low volume and no payroll. Someone is categorizing expenses and matching deposits to your bank statements. That is useful, but it is not the same as having someone review whether your business is actually running well financially. Tax preparation is almost always separate at this price point.

$750 to $1,200 per month is where most straightforward service businesses with under $1,500,000 in revenue land. At this level you should expect monthly bank reconciliations, accurate categorized transactions, quarterly or annual reporting, and some level of tax filing support. Whether that includes tax planning or just preparation varies by firm.

$1,200 to $2,000 per month and above usually means payroll is included in the package, or the business is more complex, or you are getting monthly financial review and tax strategy alongside the bookkeeping. If you are paying this much for reconciliation alone, ask why.

Our pricing at Caro & Associates starts at $750 per month. The full breakdown of what is included at each level is on the pricing page.

What Pushes the Price Up

Transaction volume

A business with 200 bank and credit card transactions a month takes longer to process than one with 40. Most bookkeeping services price at least partially on volume, even when they do not say so explicitly. Multiple revenue streams, multiple bank accounts, heavy use of payment platforms like Stripe or Square, all of that adds time.

Payroll

Payroll is often sold as an add-on, and it adds meaningfully to the monthly cost. Running payroll for six employees is different from running it for twenty-five, and some firms charge per employee on top of the base fee. If payroll is baked into the package, ask exactly what that covers: frequency, direct deposit, quarterly 941 filings, state tax remittance, and year-end W-2s are each distinct pieces.

Tax preparation and planning

Many lower-cost bookkeeping services maintain the books and then hand you off to a tax preparer in the spring. That works fine if you already have a tax advisor you trust. If not, you pay both the bookkeeper and the preparer, which can easily cost more than a single firm handling both would. A service that includes year-round tax planning within the monthly fee tends to cost more up front, but the two-bill alternative adds up.

Advisory and financial review

Reconciliation is not the same as analysis. When someone looks at your margins, spots a cash flow problem before it becomes a crisis, or tells you your labor costs are trending the wrong direction, that takes more skill and time than matching transactions to a bank feed. Services that include real financial review cost more. The difference tends to matter most around year two, when you have a track record to compare against and something specific to act on.

When the Cheaper Option Makes Sense

Not every business needs monthly accounting with advisory. If your revenue is under $500,000, your books are straightforward, and you already work with a tax advisor you trust, a $300 to $600 service may be entirely appropriate for where you are now.

Online bookkeeping services like Pilot can also be a reasonable fit for businesses at lower price points, particularly when the books are standardized and the owner has solid financial instincts. They typically do not provide deep advisory support, but not every business needs it at every stage.

The honest version: the cheaper option is fine until it is not. Most owners find out it was not fine when they need clean historical financials for a loan, or when the tax bill in April is a number they never saw coming. Our piece on what a bad bookkeeper actually costs over 12 months walks through a real example of how the gap between maintained books and reviewed books shows up in dollars.

What In-House Bookkeeping Actually Costs

This is the comparison most owners skip.

A part-time bookkeeper at 20 hours per week in Washington state runs roughly $25,000 to $35,000 per year in wages depending on experience. The Bureau of Labor Statistics puts the national median for bookkeeping, accounting, and auditing clerks at $47,440 per year for full-time work (May 2023 data), and Washington state wages run above that median.

At 20 hours a week and $25,000 to $35,000 per year in wages, you are at $2,100 to $2,900 per month before you add employer payroll taxes (roughly 8 to 10 percent) and any benefits. Call it $2,300 to $3,300 per month for the wages alone. That number does not include:

  • Tax preparation or planning
  • Anyone to review the work for accuracy
  • Software (accounting platform, payroll service) you are paying separately
  • The cost if that person leaves and takes the institutional knowledge with them

For a business between $1,000,000 and $3,000,000 in revenue, outsourced accounting at $750 to $1,200 per month typically covers more ground at lower total cost. That math does not hold at every size or complexity level, but it holds more often than owners expect.

If you want to run through the comparison for your specific situation, the how much does monthly accounting cost piece covers the broader question in more detail.

Who Outsourced Monthly Accounting Is Not For

We work with service businesses between roughly $500,000 and $10,000,000 in revenue with under 50 people. That is not everyone, and we say so clearly.

If your business is under $500,000, a lower-cost service is probably the better fit for now. If you want annual tax preparation only with no ongoing support during the year, there are options better suited to that. If you want advisory layered on top of books your current bookkeeper maintains, that is also not a fit: we do the accounting, and we do not bolt advisory onto work someone else controls.

Heavy inventory, job costing across multiple projects, multi-entity consolidations, or a business that is rapidly scaling headcount are all areas worth discussing before committing to anything, because the scope changes meaningfully.

How Onboarding Works (and What It Costs)

Most reputable bookkeeping services charge an onboarding fee. Ours is two months of the monthly rate. That covers getting your books into a state where they can be maintained properly going forward: correcting the chart of accounts, reviewing prior-year records, and handling any catch-up bookkeeping that is needed. If your books are significantly behind or disorganized, the cleanup may take longer, and a firm worth working with will tell you that before you sign anything.

Some lower-cost providers skip onboarding entirely and start from the current month forward. That is faster. It also means anything before that date may be unreliable, which matters when a lender or an auditor asks for history.

What to Ask Before You Sign

Before committing to any bookkeeping service, get clear answers on four things:

  1. What tax filings are included in the monthly fee and which are billed separately?
  2. Does someone actually review the financials each month or just process transactions?
  3. What happens during onboarding, and what is the fee?
  4. Who is your point of contact and how do you communicate with them?

A service that hesitates on any of those is worth questioning. The answers tell you more about what you are actually buying than the price does.

Questions owners ask about this

Is outsourced bookkeeping cheaper than hiring someone in-house?

For many small businesses, yes. A part-time bookkeeper in Washington state at 20 hours per week costs $2,300 to $3,300 per month in wages before benefits, and does not include tax planning or financial review. Outsourced packages in the $750 to $1,500 range often cover more ground at lower total cost. The calculation shifts once your business is large enough to justify a full-time hire with a tightly defined scope.

What is the difference between bookkeeping and accounting?

Bookkeeping is the recording of transactions: categorizing expenses, reconciling bank accounts, processing payroll. Accounting is the layer on top: reviewing those records for accuracy, preparing financial statements, filing taxes, and giving you analysis you can act on. Many outsourced services use the terms interchangeably, so ask specifically what is included before signing.

Does outsourced bookkeeping include tax preparation?

It depends entirely on the service. Lower-cost providers often handle the books but hand you off to a separate tax preparer at year-end. A full-service monthly accounting package typically includes business tax preparation and planning, and some include personal returns as an add-on. Ask what tax filings are covered and what is billed separately.

Why do some services charge $300 and others charge $2,000 for the same thing?

Because the work is not actually the same. A $300 service is typically reconciling transactions from a bank feed. A $2,000 service usually includes payroll, tax planning, monthly financial review, and advisory input. Both get called bookkeeping. The difference tends to surface at tax time or when something goes wrong with cash flow.

What does the onboarding fee cover and why is it charged?

Onboarding covers the work required to get your books into a maintainable state before the monthly routine can begin: setting up or correcting the chart of accounts, reviewing prior-year records, and doing any catch-up work. A firm that skips onboarding typically starts from the current month forward, which is faster but can leave gaps that appear when you need historical data for a lender or a tax audit.
