What Do Outsourced Accounting Services Cost in 2026?

Outsourced accounting services typically cost between $500 and $12,000 or more per month, depending on the level of support. Basic bookkeeping generally runs $500 to $1,500 per month, controller-level support costs about $2,000 to $5,000, and a complete accounting department with CFO guidance runs $5,000 to $12,000 or more.

Those ranges are a starting point, not a quote. Transaction volume, reporting requirements, accounting method, industry and the condition of your existing books all move the final number. This guide compares published pricing from several providers as of August 2026 so business owners can evaluate the market without relying on any single firm’s claims.

Outsourced Accounting Pricing at a Glance

A review of accounting firm pricing guides published in 2025 and 2026, including current figures from Breakwater Accounting + Advisory, shows four broad service tiers.

Service level	What is typically included	Typical monthly cost
Basic bookkeeping	Transaction categorization, account reconciliation, monthly financial statements	$500–$1,500
Full-service bookkeeping	Bookkeeping plus accounts payable, accounts receivable, payroll processing, bill pay	$800–$2,000
Bookkeeping and controller support	Accrual accounting, forecasting, budgets, variance analysis, management reporting	$2,000–$5,000
Full outsourced accounting department	Bookkeeping, controller oversight, CFO strategy, board reporting, financial modeling	$5,000–$12,000+

These categories are not standardized across the industry. One firm may call a package “full-service bookkeeping” while another considers the same work controller support. Many businesses also buy a blend rather than fitting neatly into one tier.

When comparing quotes, focus on the work performed, the reporting schedule and the seniority of the people doing it. The package name matters far less than the written scope.

Pricing Models Beyond the Monthly Retainer

Monthly retainers are the most common structure for ongoing work, but they are not the only option. According to KMK Ventures’ 2026 pricing guide, U.S.-based providers charge roughly $75 to $250 per hour for defined projects, and per-transaction arrangements typically run $1 to $5 per transaction.

Hourly billing suits cleanups, system migrations and other finite assignments. Per-transaction pricing can work for high-volume accounts payable or receivable when workload fluctuates month to month. Retainers give budget certainty but require a clearly defined scope up front, since vague scopes tend to produce change orders later.

What Does Each Service Level Actually Include?

The right tier depends on how complex the business has become and what management needs from its financial information.

Bookkeeping: $500 to $1,500 Per Month

Basic bookkeeping covers transaction categorization, bank and credit card reconciliation, and monthly financial statements. The business should receive an income statement — commonly called a profit and loss statement — along with a balance sheet.

This tier generally fits companies under roughly $1 million in annual revenue, with fewer than 200 monthly transactions and a straightforward legal structure. Cash-basis accounting is common at this level, meaning revenue and expenses are recorded when money changes hands.

Basic bookkeeping keeps records organized and ready for a tax preparer. It does not usually include forecasting, financial strategy or involvement in operational decisions.

Full-Service Bookkeeping: $800 to $2,000 Per Month

Full-service bookkeeping adds day-to-day financial administration. Depending on the agreement, the provider may handle accounts payable, accounts receivable, bill payments, vendor records and payroll processing, along with a more complete monthly reporting package.

This level tends to fit companies processing 200 to 500 transactions per month, maintaining several bank or credit card accounts, or employing a small team. It also suits owners who have outgrown do-it-yourself bookkeeping but do not yet need a controller.

The phrase “full-service” deserves scrutiny. Tax filing, sales tax returns, payroll fees and financial planning may still be excluded. Confirm before signing whether those functions sit inside the monthly retainer or get billed separately.

Controller-Level Support: $2,000 to $5,000 Per Month

Controller-level accounting turns the books into a management tool. Beyond supervising routine bookkeeping, a controller oversees accrual accounting, tightens the month-end close, prepares cash flow forecasts and compares actual results against budget.

The provider may also build key performance indicator dashboards and investigate why margins, expenses or cash flow diverge from expectations. Companies typically reach this point when lenders, investors or leadership can no longer make sound decisions from a basic monthly profit and loss statement.

Businesses between roughly $1 million and $5 million in revenue are common candidates, though revenue alone does not determine need. A smaller construction, e-commerce or multi-entity company may require controller oversight sooner because its accounting is inherently more complicated.

For a growing company that needs reliable reporting but is not ready to build a finance team, outsourced accounting services can provide bookkeeping and controller expertise within a single engagement.

Full Outsourced Accounting Department: $5,000 to $12,000+ Per Month

A complete outsourced finance function combines bookkeeping, accounting oversight and CFO-level guidance. The provider may prepare board or investor reporting, build financial models, maintain a 13-week cash flow forecast, and support fundraising, acquisitions or an eventual sale.

This arrangement is most common among companies above $5 million in revenue, businesses with multiple entities, or organizations with sophisticated reporting demands. It can also make sense for a smaller company preparing to raise capital or complete a transaction.

At this level the client is buying judgment, not just task completion. A senior financial professional has to understand the business, interpret its numbers and help leadership weigh decisions. That is why full-department pricing varies far more than entry-level bookkeeping rates.

What Do Accounting Firms Publish for Pricing?

Published prices help calibrate expectations, but the figures below represent different rungs on the same ladder. A bookkeeping entry price and a fractional CFO retainer are not competing offers for the same work.

Provider	Service tier represented	Published pricing	Notes
Pilot	AI-driven, cash-basis bookkeeping	Essentials from $99/month	Supports up to $100,000 in monthly expenses
Xendoo	Managed bookkeeping	Essential $395; Growth $695; Scale $995 per month	Tiers set by monthly expenses and number of accounts
Bookkeeper360	Managed bookkeeping through fractional CFO	Bookkeeping from $399/month; fractional CFO from $2,000/month	Onboarding and prior bookkeeping start at $1,000
TGG Accounting	Fractional CFO and senior financial advisory	$3,000–$10,000/month, or $150–$400/hour	CFO-level financial leadership rather than an entry-level plan

According to Pilot’s current pricing, the $99 Essentials plan covers cash-basis bookkeeping for businesses with up to $100,000 in monthly expenses. Pilot’s CFO plans run separately, beginning at $1,750 per month and rising to $5,250 per month for its custom tier, all billed annually.

Xendoo’s published plans range from $395 to $995 per month billed monthly, with roughly 10 percent off for annual billing. Its tiers are gated by monthly expense volume — $50,000, $75,000 and $125,000 respectively — and by the number of bank and credit card accounts requiring reconciliation. Xendoo also offers fractional CFO support from $1,500 per month, though it is sold only as an add-on to an existing monthly accounting plan, which puts the practical entry point closer to $1,900.

Bookkeeper360’s pricing page lists monthly bookkeeping from $399, weekly service from $599, and fractional CFO support starting at $2,000 per month. A separate CFO advisory page on the same site shows a lower entry figure, so the $2,000 amount here refers specifically to the main pricing page. Onboarding and prior bookkeeping work start at $1,000 and are billed separately.

TGG Accounting publishes a fractional CFO range of $3,000 to $10,000 per month, or $150 to $400 per hour depending on experience and scope.

The pattern is worth naming. Entry-level pricing and senior-advisory pricing measure different things. A standardized package buys defined task completion; a controller or CFO engagement buys interpretation, forecasting and financial leadership from someone expected to help management make decisions. Technology-led providers can publish a low entry price because the work is repeatable. Advisory firms tend to scope each engagement because responsibilities vary substantially from one client to the next.

What Determines Your Quote?

Two companies with identical revenue can receive very different proposals. These factors explain most of the gap.

Transaction Volume

Volume is the single biggest driver. More sales, purchases, deposits and payments mean more to categorize and reconcile. Some firms price directly on transaction count; others use monthly expenses as a proxy.

Number of Financial Accounts

Every bank account, credit card, payment processor and merchant platform has to be reconciled. A company running one operating account is far simpler than a business collecting through several processors and paying across a dozen cards.

Cash or Accrual Accounting

Cash-basis bookkeeping records transactions when money moves. Accrual accounting recognizes revenue when earned and expenses when incurred, which requires more judgment and more month-end work. Accrual often becomes mandatory once a company has outside investors, lender covenants or GAAP reporting obligations.

Number of Entities

Each legal entity may need its own books, reconciliations and financial statements. If management also wants consolidated reporting, the provider has to account for intercompany transactions and eliminate duplicate activity.

Industry Requirements

Some industries need accounting that generic packages do not cover. Construction businesses often require job costing, progress billing and retainage tracking — LaJolla.com’s guide to San Diego construction accounting companies covers why industry familiarity matters in that field. E-commerce companies may need multi-channel inventory reporting. Real estate firms often require property-level financials, and professional services companies track work in progress. Each adds time and specialized expertise.

Seniority of the Team

An hour of bookkeeping and an hour of CFO strategy are not priced alike. A lower quote may rely mostly on a bookkeeper; a higher one may include regular controller review and direct CFO access. Ask who performs the work, who reviews it, and how often a senior professional will meet with management.

Condition of the Existing Books

Disorganized books make the first months considerably more expensive. The firm may need to reconcile stale accounts, correct misclassified transactions or rebuild prior-period statements before regular work begins.

Cleanup is the most common surprise on a first invoice. Breakwater places catch-up work at roughly $1,000 to $5,000 or more depending on backlog, and Xendoo prices its catch-up bookkeeping service separately from $295 per month. A provider should review the books and quote the cleanup scope before the engagement starts.

Is Outsourced Accounting Cheaper Than Hiring In-House?

Outsourcing is generally less expensive when a small or midsize company needs several levels of financial expertise but not enough work to keep a full accounting department busy. The comparison narrows as the business grows and needs dedicated daily access to its finance team.

These are not equivalent line items. A staff hire is dedicated and builds institutional knowledge over time; an outsourced package may divide the work among bookkeepers, accountants and senior advisors. The figures below compare cost, not identical staffing arrangements.

According to the 2026 Robert Half Salary Guide, an assistant controller in San Diego carries a projected starting salary of $115,620 to $174,660. That role — rather than a corporate controller — is the realistic comparison for a business weighing controller-level outsourced support.

Salary is only part of the cost. The U.S. Bureau of Labor Statistics reported that private-industry wages averaged $32.60 per hour in March 2026 while benefits averaged another $14.01, meaning benefits added roughly 43 percent on top of wages.

Applying that ratio to the low end of the assistant controller range puts estimated compensation near $165,000 per year, before recruiting costs, accounting software, training or the expense of covering a vacancy.

A controller-tier outsourced engagement at $2,000 to $5,000 per month costs $24,000 to $60,000 annually. That does not mean a $24,000 package replaces every responsibility of a full-time assistant controller. It shows the difference between buying a defined quantity of controller oversight and employing someone in the role year-round.

For companies that need more senior in-house leadership, Robert Half places the San Diego corporate controller range at $186,960 to $262,298. That position typically oversees an entire accounting function and is not the right benchmark for a business shopping a mid-tier outsourced package.

Consideration	In-house assistant controller	Outsourced controller-level support
Annual cost	Salary plus benefits and employment overhead	$24,000–$60,000 based on scope
Coverage	Depends on one employee	Provider may supply backup coverage
Range of expertise	Limited to that person’s experience	May include bookkeeper, controller and CFO access
Availability	Dedicated to one employer	Shared across clients
Institutional knowledge	Deepens over time	Depends on communication and engagement length
Recruiting	Employer’s responsibility	Provider staffs the engagement

Outsourcing usually holds the cost advantage below roughly $5 million in revenue. Above that, or where the role demands constant availability, close daily collaboration and deep institutional knowledge, an in-house hire may justify the premium.

What Hidden Costs Should You Ask About?

A low headline price gets less attractive once necessary add-ons appear. Ask about each of these before comparing proposals:

• Onboarding and accounting system setup
• Catch-up work for prior months or years
• Business and personal tax returns
• Payroll processing and per-employee charges
• Accounts payable and receivable support
• Sales tax returns and registrations
• Accounting software subscriptions
• 1099 preparation and filing
• Automatic price increases when transaction or expense thresholds are crossed

Current provider pricing shows why this matters. Bookkeeper360 lists onboarding from $1,000, payroll from $200 per month and back-office services from $150 per month. Xendoo moves clients into higher plans as monthly expenses and account counts grow, and bills business tax filing separately from $1,245 per year. Pilot requires its tax services to be purchased alongside Pilot Bookkeeping.

Get an itemized scope in writing. Compare quotes using the same accounting method, reporting schedule, transaction volume and add-ons. Comparing headline prices without matching scope can make the cheapest proposal look more complete than it is.

How Should You Choose an Outsourced Accounting Partner?

Price should not be the deciding factor. Look for experience in your industry, a defined month-end close schedule and a clear communication cadence. Confirm who performs the routine work, whether a controller reviews the financial statements, which responsibilities stay with your staff, and how quickly the provider responds when management needs an answer. Ask for references from companies at a similar revenue stage with comparable reporting requirements.

The proposal should also state plainly what is excluded. Tax returns, payroll, sales tax filings, cleanup work and software costs can change the real number considerably. Ask how the engagement and the fee will change if transaction volume or business complexity increases.

Businesses seeking local options can review LaJolla.com’s list of the best accounting companies in San Diego. Among San Diego firms working at the controller and CFO end of the market, TGG Accounting was founded in 2006 by Matt Garrett, a Vanderbilt graduate who had built and sold several businesses before starting the firm to give smaller companies the kind of financial information large enterprises take for granted. TGG structures its work around a documented methodology it calls The TGG Way™ and reports serving companies with annual revenue up to approximately $100 million.

The strongest proposal is rarely the one with the lowest monthly fee. It is the one that states clearly who will do the work, what the company will receive, and which costs could surface later.

Frequently Asked Questions

What is a typical monthly cost for outsourced accounting services?

Typical costs range from $500 per month for basic bookkeeping to more than $12,000 for a complete accounting department with CFO guidance. Transaction volume, reporting needs, industry complexity and the condition of the existing books determine where a business lands.

Is outsourced accounting cheaper than hiring in-house?

Usually, for small and midsize businesses that need bookkeeping, controller and CFO expertise but not several full-time employees. An in-house assistant controller in San Diego costs roughly $165,000 fully loaded, while controller-tier outsourced support runs $24,000 to $60,000 annually for a defined scope of work.

How much does a fractional CFO cost?

TGG Accounting publishes a range of $3,000 to $10,000 per month, or $150 to $400 per hour. Pilot lists CFO plans from $1,750 per month, Bookkeeper360’s pricing page shows fractional CFO support from $2,000 per month, and Xendoo offers CFO support from $1,500 per month as an add-on to an existing accounting plan.

What is the difference between a bookkeeper, a controller and a CFO?

A bookkeeper records and reconciles transactions. A controller oversees accounting accuracy, internal reporting and the month-end close. A CFO uses financial information to guide cash flow, funding, growth and other major business decisions.

How much should a business budget for accounting?

Published benchmarks put total accounting spend at roughly 1 to 4 percent of annual revenue, trending toward the lower end as revenue grows. A company around $1 million in revenue commonly spends $10,000 to $20,000 per year. Multi-entity structures, accrual accounting and industry-specific reporting push the figure higher.

Do outsourced accounting firms handle tax filing?

Some do, but tax filing is frequently sold separately. Xendoo bills business tax filing from $1,245 per year on top of its monthly plans, and Pilot requires tax services to be bought alongside bookkeeping. Confirm whether a quote covers federal and state returns, sales tax filings, tax planning and correspondence with tax authorities.

What does bookkeeping cleanup cost?

Catch-up work is quoted separately from ongoing service, commonly $1,000 to $5,000 or more depending on how far behind the books are. Xendoo prices catch-up bookkeeping from $295 per month. Cleanup frequently costs more than several months of regular service because untangling misclassified transactions is harder than maintaining accurate books.
