If you are wondering how much a bookkeeping service costs for a small business, the answer depends entirely on who does the actual work. As of October 2026, doing the work yourself using accounting software costs between $0 and $340 per month. Hiring a dedicated bookkeeping service to reconcile your accounts for you starts at $199 per month (Bench Bookkeeping Light) or $399 per month (Bookkeeper360 monthly bookkeeping), and published tiers reach $649 a month (Bench Bookkeeping + Tax). Handing the entire process over to a local CPA depends on the firm and your region, and no local CPA price is published to compare.

The cost you pay dictates the level of responsibility you shift away from yourself. Software organizes the numbers, a bookkeeping service inputs and reconciles the numbers, and an accountant interprets them for tax strategy and compliance. However, no service completely removes your obligation to keep accurate original records.

The Foundation of Small Business Bookkeeping

Before you can choose between a bookkeeper, an accountant, or a software platform, you have to meet the baseline requirements set by the federal government. Bookkeeping is not just about understanding your profit margins. It is a strict legal requirement designed to verify your tax burden.

The Internal Revenue Service sets out specific rules for how a business must behave financially. In Publication 583, the IRS states that one of the first things you should do when you start a business is open a business checking account. You should keep your business account separate from your personal checking account. This separation is the absolute prerequisite for any bookkeeping system. If your personal groceries and your business supplies are on the same bank statement, no software or professional can efficiently balance your books.

You must use the business account for business purposes only. The IRS instructs business owners to indicate the source of deposits and the type of expense directly in the checkbook. This business checkbook serves as your basic source of information for recording your business expenses. If you cannot keep your funds separated, a bookkeeper will charge you a premium to untangle the mess, and an auditor will view your records with immediate suspicion.

For owners who are just starting out, managing these foundational steps can feel overwhelming. Someone forming a business now needs the legal entity, the Employer Identification Number, a separate business checking account, and then an accounting system, in exactly that order. Establishing your company correctly makes the subsequent bookkeeping infinitely easier. Platforms that handle formation often provide the best starting point for a brand new enterprise. For example, you can handle your entity formation, registered agent services, and initial compliance through ZenBusiness accounting, which bundles the necessary legal setup with a free accounting consultation to get you pointed in the right direction.

The Document Trail You Are Responsible For

No matter which bookkeeping option you choose, you are solely responsible for generating and preserving the supporting documents. A bookkeeper will log an expense, but they cannot invent the receipt. An accountant will claim a deduction, but they cannot fabricate the invoice.

The IRS explicitly names the types of supporting documents you must keep to verify the entries in your books. According to Publication 583, gross receipts must be supported by cash register tapes, bank deposit slips, receipt books, invoices, and credit card charge slips. If you claim you made money, you must have the paper trail proving exactly when and how it arrived.

Purchases and inventory require their own specific proof. The IRS lists canceled checks, cash register tape receipts, credit card sales slips, and invoices as the required supporting documents for purchases. If you buy materials to manufacture a product, the ledger entry is meaningless without the corresponding invoice and proof of payment.

Expenses and assets carry similar burdens of proof. Business expenses must be backed by canceled checks, cash register tapes, account statements, credit card sales slips, and invoices. Assets require purchase and sales invoices, real estate closing statements, and canceled checks. A bookkeeper's job is to organize this mountain of paper into a legible financial statement. Your job is to make sure the paper actually exists.

Record Retention: What the Government Expects

Understanding how long to keep these records is just as critical as generating them. The cost of a bookkeeping service often includes digital storage and organization, but you need to know the legal timelines to ensure you are paying for adequate archiving.

The general rule from the IRS is that you must keep records for three years. This default period applies to most standard tax returns and supporting documents. However, there are strict exceptions based on specific financial events and the accuracy of your filings.

You must keep records for six years if you do not report income that you should report, and it is more than 25 percent of the gross income shown on your return. If you file a claim for a loss from worthless securities or a bad debt deduction, the IRS requires you to retain those specific records for seven years. If you do not file a return at all, or if you file a fraudulent return, you must keep your records indefinitely.

Taxes related to your staff carry their own specific timelines. The IRS dictates that you must keep all employment tax records for at least four years after the date the tax becomes due or is paid, whichever is later. This includes records of wages paid, payroll deductions, and the dates of employment.

Federal labor laws also dictate how long you hold onto specific operational data. The U.S. Department of Labor enforces the Fair Labor Standards Act, which carries distinct recordkeeping requirements. According to DOL Fact Sheet 21, each employer shall preserve for at least three years payroll records, collective bargaining agreements, sales and purchase records.

The DOL also sets rules for the raw data used to calculate that payroll. You must keep supporting records for two years. This category includes time cards, piece work tickets, wage rate tables, work and time schedules, and records of additions to or deductions from wages. Your bookkeeping software or service must be configured to hold this data for the full legally required duration.

Finally, state laws can impose longer retention periods than the federal government. For example, the California Department of Tax and Fee Administration outlines strict rules for sales tax documentation. Under CDTFA Publication 116, California businesses must keep sales and use tax records for at least four years. If you are actively being audited by the state, you must retain all records covering the audit period until the audit is complete, even if that stretches beyond the standard four years.

What Each Option Costs and What It Does

When evaluating the cost of bookkeeping, you have to look at the exact services provided. The list below covers the major options alphabetically. This order is strictly alphabetical and does not represent a ranking or editorial preference.

Prices change frequently in the software and service industries. Every dollar figure listed below was verified on the provider's official pricing page as of October 6, 2026.

Bench

Bench is a dedicated bookkeeping service rather than a software tool you manage yourself. You provide access to your accounts, and their team categorizes your transactions, reconciles your bank statements, and generates monthly financial reports. This shifts the daily labor of bookkeeping off your desk entirely.

As of October 2026, the Bench Bookkeeping Light plan costs $199 per month. Their standard Bookkeeping plan is $399 per month, and their combined Bookkeeping + Tax plan is $649 per month. If your business requires highly customized attention, Bench offers a fractional bookkeeper at $55 per hour, plus a $1,200 onboarding fee.

Bookkeeper360

Bookkeeper360 offers outsourced bookkeeping services tailored for businesses that want human oversight without hiring a full-time employee. They manage your daily transaction categorization and provide regular financial insights. They also offer add-on services for back-office tasks.

Their monthly bookkeeping service starts at $399 per month. If your business has a higher transaction volume and requires weekly bookkeeping, the service starts at $599 per month. Bookkeeper360 also offers payroll administration starting at $200 per month. New clients should expect an onboarding fee starting from $1,000 to get their historical books in order.

QuickBooks Experts

QuickBooks Experts is an assisted bookkeeping service provided directly by Intuit. Instead of just selling you the software, Intuit pairs you with a dedicated bookkeeping professional who helps you manage your QuickBooks account, reconcile your statements, and close your books each month.

Intuit does not publish a standard price for QuickBooks Experts on its pricing page. Because the service is scaled to the exact transaction volume and complexity of your business, you have to contact their sales team for a custom quote.

QuickBooks Online

QuickBooks Online is the industry standard for do-it-yourself accounting software. You pay for access to the platform, but you or your staff are entirely responsible for categorizing expenses, matching receipts, and generating accurate reports.

The pricing scales based on the features you need. Intuit offers a Free tier at $0 for very basic needs. The Simple Start plan is $38 per month. The Essentials plan is $85 per month. The Plus plan is $140 per month, and the Advanced plan costs $340 per month. Intuit currently offers a promotional rate of 50 percent off for three months, but that is a temporary discount, not the ongoing baseline cost.

Xero

Xero is a cloud-based accounting software platform designed as a direct alternative to QuickBooks. Like other software options, you are paying for the tool, not the labor. You are responsible for ensuring the data entered into Xero matches your actual bank statements.

The Early plan costs $27 per month and limits the number of invoices and bills you can process. The Growing plan is $59 per month and removes those strict transaction limits. The Established plan is $97 per month and adds features like multi-currency support and project tracking. Xero currently advertises a promotional rate of 80 percent off for three months, which is a temporary introductory offer.

A Local CPA

Hiring a Certified Public Accountant is fundamentally different from hiring a bookkeeper or buying software. A local CPA provides tax strategy, ensures complex regulatory compliance, and offers professional representation if you are audited. They often oversee a bookkeeper's work rather than doing the daily data entry themselves.

There is no published standard price for a local CPA. Rates vary wildly by firm, by region, and by the specific complexity of your corporate structure. A CPA in a major coastal city reviewing a multi-state corporate return will charge significantly more than a CPA in a rural area handling a simple single-member LLC.

ZenBusiness Money Pro

ZenBusiness is primarily known for helping entrepreneurs form their business entities, but they also offer a dedicated bookkeeping tool. ZenBusiness Money Pro is a service add-on designed to handle the immediate financial needs of a newly formed company without forcing the owner to learn complex accounting software.

ZenBusiness Money Pro costs $30 per month. It covers custom invoicing, revenue and expense tracking, and basic tax preparation tools. Because the platform already handles your legal formation and compliance, adding their bookkeeping service allows a new business owner to manage their entity and their basic finances through a single provider. It is the most logical step for an owner who wants to keep their administrative overhead as low as possible while they launch.

Comparing Responsibility: Who Takes the Blame?

Cost is only one half of the equation. The other half is liability. When you pay for one of these options, you need to know exactly what kind of risk you are transferring away from yourself, and what kind of risk you still hold.

When you use software like QuickBooks Online or Xero, you carry 100 percent of the responsibility. The software is just a calculator with a database attached. If you categorize a personal dinner as a business travel expense, the software will happily generate a tax report claiming that deduction. If the IRS audits you, the software company holds zero liability for your incorrect entries. You are entirely on the hook for the mistakes, the back taxes, and the penalties.

When you hire a bookkeeping service like Bench or Bookkeeper360, you transfer the labor, but you do not necessarily transfer the ultimate legal liability. A bookkeeper is responsible for accurately entering the data you provide. If you hand them a bank statement, they will reconcile it perfectly. However, if you hide a cash transaction or fail to provide the supporting invoices for a major purchase, the bookkeeper cannot be blamed for the omission. They organize the reality you show them. If your underlying records are flawed, the IRS will still hold you, the business owner, accountable for the discrepancy.

Hiring a CPA changes the dynamic slightly. A Certified Public Accountant carries a professional license and is bound by strict ethical and legal standards. They are responsible for applying the tax code correctly to your financial situation. If a CPA makes a gross error in interpreting tax law, they carry professional liability and can face sanctions from their licensing board. However, a CPA still relies on the data you or your bookkeeper provide. If you lie to your CPA, or if your underlying records are fraudulently altered, the CPA is not liable for your deception. The business owner always remains the primary target of any tax enforcement action.

Making the Right Choice for Your Business Phase

Choosing between these options usually comes down to the current complexity of your operations. You do not need a high-end accounting firm when you have zero revenue, and you should not be relying on a free software tier when you have fifty employees.

If you are pre-revenue or just starting out, keeping things simple is the best strategy. Your primary goal is to establish the legal entity, get the EIN, open the business bank account, and start tracking initial expenses. A unified service that handles formation alongside basic financial tracking is usually the smartest play. This keeps your costs low and prevents you from getting bogged down in software features you do not yet need.

Once you have consistent daily transactions, DIY software becomes the logical next step. A subscription such as Xero Early at $27 a month or QuickBooks Online Simple Start at $38 a month gives you the tools to send invoices, track payments, and categorize expenses. This phase requires discipline. You must dedicate time every single week to logging your supporting documents and reconciling your bank feeds. If you let the software sit idle for three months, catching up will become a massive administrative burden.

When the volume of transactions makes DIY bookkeeping too time-consuming, it is time to hire a service. Paying for a service tier, which runs from $199 to $649 a month at Bench as of October 6, 2026, is easily justified if it saves you ten hours of data entry each week. Your time as an owner is better spent generating revenue than hunting down a twenty-dollar discrepancy in a ledger. A service ensures your books are closed accurately every month, giving you reliable financial data to make business decisions.

Finally, when your tax situation becomes complex, you need an accountant. If you are dealing with multi-state sales tax, depreciation of large physical assets, or complex payroll structures, a CPA is no longer optional. The fees you pay a CPA are an investment in legal safety and tax optimization. They take the clean books provided by your software or your bookkeeper and use them to ensure you pay exactly what you owe the government, and not a penny more.
