Outsourced accounting services cost $300–$1,200 per month for most small businesses in 2026: basic bookkeeping runs $200–$500, full accounting $500–$2,000, and fractional CFO advisory $1,500–$5,000 a month.
Frequently Asked Questions
Q
How much do outsourced accounting services cost per month in 2026?
Most US small businesses pay $300–$1,200 per month for outsourced accounting in 2026. Basic bookkeeping alone runs $200–$500, full-service accounting (books, tax, and financial reports) runs $500–$2,000, and fractional CFO or advisory work runs $1,500–$5,000. Pricing scales with transaction volume, entity complexity, and region, so a solo sole proprietor sits near the floor while a mid-size S-corp lands toward the top.
Typical all-in range: $300–$1,200 per month
Bookkeeping only: $200–$500 per month
Full accounting (books + tax + reports): $500–$2,000 per month
Fractional CFO / advisory: $1,500–$5,000 per month
Annualized, most small businesses spend $3,600–$14,400 per year

Q
Is it cheaper to hire a bookkeeper or a full-service accounting firm?
A standalone bookkeeper is cheaper month to month — $200–$500 for outsourced bookkeeping versus $500–$2,000 for full accounting — but a bookkeeper does not file taxes or give strategic advice. Many small businesses pair a bookkeeper at $40–$90 per hour with a CPA who handles the annual return for $800–$2,000. A bundled full-service firm costs more per month but removes the coordination work and the year-end tax surprise.
Outsourced bookkeeping: $200–$500 per month or $40–$90 per hour
Full-service accounting firm: $500–$2,000 per month
CPA annual tax return (added on): $800–$2,000
DIY software (QuickBooks Online): $35–$235 per month
Bundling books + tax usually beats hiring each separately
Q
How much does a small business accountant charge per hour?
Hourly rates depend on credential and task. A bookkeeper charges $40–$90 per hour, a non-CPA accountant $60–$150, and a licensed CPA $150–$450 per hour for advisory and tax work. Because hourly billing is unpredictable, most outsourced providers now quote a flat monthly fee tied to transaction volume, which is what this calculator estimates.
Bookkeeper: $40–$90 per hour
Staff accountant (non-CPA): $60–$150 per hour
Licensed CPA: $150–$450 per hour
Flat monthly retainers usually undercut hourly for steady work
Most firms cap or estimate hours up front to avoid bill shock
Q
Does my entity type (LLC, S-corp, sole prop) change accounting costs?
Yes. A sole proprietor files a simple Schedule C, so books and tax prep stay cheap ($300–$600 for the return). An LLC taxed as a pass-through is similar. An S-corp must run payroll, track owner reasonable compensation, and file Form 1120-S, which adds bookkeeping work and pushes tax prep to $800–$2,000. Electing S-corp status can still save on self-employment tax, but plan for $100–$400 more per month in accounting.
Sole proprietor / single-member LLC: simplest, lowest cost
Schedule C tax return: $300–$600
S-corp return (Form 1120-S): $800–$2,000
S-corp adds required payroll and reasonable-comp tracking
Budget $100–$400 more per month once you elect S-corp
Q
Should I outsource accounting or hire in-house?
Outsourcing wins until you are large enough to keep a full-time hire busy. An in-house full-charge bookkeeper costs $45,000–$65,000 in salary plus 20–30% in benefits and payroll taxes — roughly $55,000–$85,000 fully loaded — before software and training. Outsourced accounting at $300–$1,200 per month ($3,600–$14,400 per year) covers most businesses under about $5M in revenue for a fraction of that, with no hiring, turnover, or coverage risk.
In-house bookkeeper salary: $45,000–$65,000 plus benefits
Fully loaded in-house cost: ~$55,000–$85,000 per year
Outsourced equivalent: $3,600–$14,400 per year
Outsourcing removes turnover, sick days, and software overhead
In-house starts paying off above roughly $5M in revenue

Fractional CFO work — forecasting, board reporting, cash-flow modeling — on top of high-volume books and S-corp payroll in a premium labor market lands at the top of the range, still well below a full-time finance hire.
Outsourced accounting is priced from a base scope tier, then adjusted for transaction volume, entity complexity, and local labor rates. Start from the scope midpoint and layer the other three drivers on top.
Where:
Base scope fee= Bookkeeping $200–$500, full accounting $500–$2,000, or CFO advisory $1,500–$5,000 per month
Volume adjustment= Higher monthly transaction counts add work — firms tier pricing by number of transactions and connected accounts
Entity complexity= S-corp payroll and Form 1120-S add roughly $100–$400 per month over a sole proprietor
Regional multiplier= High-cost metros (NYC, SF, Boston) run 20–40% above the national average; South and Midwest run below
To decide whether to keep accounting outsourced, annualize the monthly fee and compare it to the fully loaded cost of an in-house hire including benefits, payroll taxes, and software.
Where:
Salary= Full-charge bookkeeper $45,000–$65,000; controller $90,000–$160,000 per year

Accounting Services Costs in 2026: What Small Businesses Actually Pay
1
What Outsourced Accounting Services Cost in 2026
Outsourced accounting is one of the few recurring professional fees a small business pays every single month, so getting the number right matters for cash flow. In 2026, the typical US small business spends $300 to $1,200 per month, or roughly $3,600 to $14,400 a year. That headline range hides a wide spread, because "accounting services" can mean anything from a part-time bookkeeper categorizing transactions to a fractional CFO building three-statement forecasts for a venture-backed company.
The single biggest driver is service scope. Basic bookkeeping — reconciling accounts, categorizing transactions, and producing a monthly profit-and-loss statement — runs $200 to $500 per month. Full-service accounting that adds tax preparation, financial reporting, and light advisory work runs $500 to $2,000. Fractional CFO or controller-level advisory work, which layers forecasting, budgeting, and strategic guidance on top of the books, runs $1,500 to $5,000 per month. Use the calculator above to land on a figure for your size and scope, then read on to understand what each input is really pricing.
It helps to know what the monthly fee does and does not include. A standard retainer covers categorizing transactions, reconciling your bank and credit-card accounts, and delivering a monthly profit-and-loss statement and balance sheet. It usually excludes the annual tax return, which most firms bill separately at $300 to $2,000 depending on entity type, plus payroll, sales-tax filings, and any cleanup of prior-period books. When you compare two quotes, confirm whether the tax return is bundled or billed on top, because that one line item can swing the true annual cost by more than a thousand dollars.

Most providers now quote a flat monthly retainer tied to transaction volume instead of billing by the hour — it makes budgeting predictable and removes the year-end bill shock that hourly engagements are known for.

Seven Factors That Move Your Monthly Accounting Bill
Two businesses with identical revenue can receive quotes that differ by hundreds of dollars a month, and the variance is rarely random. Accounting firms price from a base scope tier and then adjust for the workload your specific business creates. The more transactions, accounts, and tax complexity you bring, the more hours the firm has to staff against your account — and labor is the overwhelming majority of what you are paying for.
Read every quote against the list below. If a provider cannot explain how your transaction volume or entity type maps to their price, that is a sign the quote is a guess that will be revised upward once they see your books.
Ask whether catch-up bookkeeping is included before the first monthly invoice. Cleaning up a year of neglected or miscategorized books is the most common surprise line item, and it is almost always billed separately from the recurring fee.
Service scope: bookkeeping ($200–$500), full accounting ($500–$2,000), or CFO advisory ($1,500–$5,000) per month
Transaction volume: the primary volume driver — firms tier pricing by the number of monthly transactions and connected bank, card, and loan accounts
Entity type: an S-corp adds payroll and Form 1120-S work that a sole proprietor never touches
Revenue and business size: larger operations need more reconciliations, departmental reporting, and accrual-basis books
Region and labor rate: high-cost metros run 20–40% above the national average; the South and Midwest run below it
Cleanup and catch-up: messy or behind books carry a one-time onboarding fee of $500–$5,000 before monthly service begins
Add-ons: payroll, sales-tax filings, 1099 processing, and accounts-payable management each stack onto the base fee

Bookkeeping vs Full Accounting vs Fractional CFO
The words "bookkeeping" and "accounting" get used interchangeably, but they buy very different things, and overpaying happens when a business orders a tier it does not yet need. Bookkeeping is the recording layer: categorizing transactions, reconciling accounts, and producing monthly statements. If that is all you need, a standalone bookkeeper is the cheapest path, and the bookkeeping services cost calculator prices that tier in isolation so you can see exactly where the floor sits before adding anything else.
Full accounting builds on bookkeeping with tax strategy, compliance filings, and interpretation of the numbers — the work that actually requires a CPA or experienced accountant. Fractional CFO service is a different product again: it is forward-looking financial leadership for businesses that have outgrown simple reporting but cannot justify a six-figure full-time hire. The table below shows what each tier includes and who it fits, so you can match spend to the stage your business is actually in.
There is also a practical sequence most businesses follow as they grow. They start on software alone, move to outsourced bookkeeping once transactions outpace their patience, add full accounting when tax complexity or a lender demands clean financials, and bring in fractional CFO help only when they are raising capital or managing real cash-flow decisions. Paying for the next tier a stage too early rarely pays off, and a stressful tax season is usually the trigger that finally justifies the upgrade to full accounting.

Buy the tier your decisions require, not the most impressive one. A pre-revenue startup paying for fractional CFO work is overspending; a $3M company running on bookkeeping alone is flying blind at tax time.
4
How Entity Type and Transaction Volume Change the Price
Beyond scope, the two inputs that move an accounting quote the most are your entity type and your monthly transaction volume. A sole proprietor or single-member LLC files a Schedule C attached to a personal return, which keeps both bookkeeping and tax preparation simple — a Schedule C typically costs $300 to $600 to prepare. The books are lighter because there is no separate payroll, no owner-compensation tracking, and one set of accounts to reconcile.
Electing S-corp taxation changes the math. An S-corp must run payroll for its owner, document reasonable compensation, and file a separate Form 1120-S corporate return that runs $800 to $2,000. That added compliance typically adds $100 to $400 per month to ongoing accounting, even though the self-employment-tax savings often still make the election worthwhile above roughly $60,000 in profit. Transaction volume then layers on top of entity complexity, because most firms tier their monthly fee directly by how many transactions and connected accounts they have to reconcile.
Volume matters because reconciliation is the labor-intensive heart of bookkeeping. A business running 40 transactions a month across a single checking account is a fraction of the work of one processing 400 transactions across several cards, a line of credit, and a merchant processor. That is why two companies with identical revenue can sit in different pricing tiers: a high-ticket consultancy with 30 invoices a month is cheaper to keep books for than a busy online store with hundreds of small charges, refunds, and payouts to reconcile every period.
Sole proprietor / single-member LLC: simplest books, Schedule C return $300–$600
Multi-member LLC or partnership: adds Form 1065 and partner K-1s
S-corp: required payroll, reasonable-comp tracking, Form 1120-S $800–$2,000
Under ~100 transactions/month: lowest bookkeeping tier
300+ transactions/month or multiple connected accounts: expect a higher tier or per-transaction pricing
5
In-House vs Outsourced vs Accounting Software
Once you know your monthly figure, the next question is whether outsourcing is even the right model. The three options are DIY software, outsourced services, and an in-house hire, and they fit different stages. Accounting software like QuickBooks Online costs $35 to $235 per month and works while transaction volume is low and you have the time and discipline to keep the books current. The hidden cost is your own hours and the risk of errors that surface as penalties or a painful tax-season cleanup.
Outsourcing at $300 to $1,200 per month is the sweet spot for most businesses up to about $5M in revenue. An in-house full-charge bookkeeper earning $45,000 to $65,000 plus 20–30% in benefits and payroll taxes costs roughly $55,000 to $85,000 fully loaded — far more than outsourcing, and only worthwhile once the role is genuinely full-time. If you are also adding staff, the payroll services cost calculator estimates the per-employee processing fees that an S-corp election or first W-2 hire triggers, and the virtual assistant cost calculator covers the admin and data-entry tasks that often get bundled into a bookkeeping engagement.

How to Hire an Accountant and What to Watch For
The cheapest accounting engagement is the one you do not have to redo, so vet providers on fit and transparency rather than headline price alone. Get two or three written quotes that spell out scope, the transaction-volume tier they assume, what triggers a price increase, and whether catch-up work is included. A quote that is dramatically below the others usually assumes a lower volume tier than your real books or excludes the tax return entirely — the gap reappears as a change order within the first quarter.
Confirm credentials and software fit before you sign. For tax-sensitive work you want a CPA or an enrolled agent who can represent you before the IRS, not just a bookkeeper. Make sure they work in your accounting platform and your industry, and clarify response times and who actually does the work day to day. The steps below walk the hiring decision in order, and if you are weighing other professional-service fees at the same time, the mortgage broker fee calculator and the rest of the finance category use the same quote-comparison discipline.
Finally, treat the relationship as ongoing rather than transactional. The best accountants flag issues before they become penalties, suggest tax moves before year-end while there is still time to act, and scale their service as you grow. Agree up front on how often you will meet, who your day-to-day contact is, and what reports land in your inbox each month. A provider who only surfaces at tax time is a bookkeeper with a markup, not the financial partner that the higher service tiers are supposed to buy.
Never choose an accountant on monthly price alone. A firm that misclassifies transactions or misses a filing deadline costs far more in penalties and rework than the $100–$300 a month you saved picking the lowest bid.
1
Define scope
Decide whether you need bookkeeping, full accounting, or CFO advisory before requesting quotes so the numbers are comparable.
2
Collect two to three quotes
Insist each one states the assumed transaction-volume tier, included tax filings, and what triggers a price increase.
3
Verify credentials
For tax work, confirm a CPA or enrolled agent; for books alone, a certified bookkeeper with references is enough.
4
Check software and industry fit
Confirm they work in your platform (QuickBooks, Xero, NetSuite) and understand your industry's tax treatment.
5
Clarify catch-up and onboarding
Pin down any one-time cleanup fee ($500–$5,000) before the recurring monthly invoice starts.
