Bookkeeping Cost Per Month: What Drives a Small Business Fee

Is there a standard or going rate for monthly bookkeeping?

No. No federal or state source sets a bookkeeping price. In most cases the IRS requires no particular method, only a system that clearly shows income and expenses and supports what the return reports (Publication 583). A quote therefore prices the scope a firm agrees to do each month, whether it comes from an independent bookkeeper, an accounting firm or an online service. A "going rate per transaction" is one way a firm may count that work, not a standard.

A quote is hard to judge when any of these apply:

• Payroll, contractor forms or sales tax returns are part of the work.
• The business has several bank, card, loan or payment-platform accounts, or sells through a platform whose payouts differ from its sales.
• Inventory, more than one entity, or owner money mixed with business money is involved.
• Months are unbooked, or a lender or a notice sets a date.

If two or more apply, settle what the quote covers before comparing its price: the scope, which parts are monthly and which are one-time catch-up, and whether the same firm carries the books through to the tax return.

Gather before asking anyone to price it: the quote or fee-increase letter, every bank, card, loan and payment account with its transactions per month, the number of employees and contractors paid, the states where you collect sales tax, and how far behind the books are. For what a monthly service should deliver, see what a monthly bookkeeping service includes.

What work makes a month of bookkeeping bigger?

Accounts, transaction counts, payroll, contractors, sales tax and platforms each add work, and revenue alone does not size it. A business with a few large invoices and a business with the same sales spread over hundreds of small orders do not hold the same month.

Does payroll add to the monthly fee, and what is filed and when?

Payroll adds recurring work whoever does it: pay and withholding each pay period, tax deposits, quarterly and annual returns, and year-end wage statements. Whether that sits inside the monthly fee, on its own line or with a payroll provider is a scope term, so the quote has to say which. With a payroll service provider or reporting agent, the employer stays responsible for the deposits and returns (Publication 15). A contract with a certified professional employer organization can change who is the employer for the wages it covers (same publication), so the quote should name the arrangement. The books still record each payroll and tie to them.

If the IRS has told you in writing to file Form 944, you file that annual return instead of Forms 941. A due date on a weekend or legal holiday moves to the next business day, and depositing the tax does not replace filing the return (IRS due dates). A late deposit carries a penalty of 2% to 15% of the unpaid deposit, depending on how late (IRS). Unpaid withheld tax can also reach people personally: a responsible person who willfully fails to collect or pay it over can owe 100% of the unpaid amount, the trust fund recovery penalty.

State withholding and unemployment accounts have their own dates. Deposit schedules, the next-day rule and state payroll accounts are in setting up payroll; for staff in more than one state, see employees in another state.

Which contractor and sales tax duties add work?

Contractors add taxpayer-information requests, year-end forms and sometimes withholding. Sales tax adds a return, on a state schedule, for every state where the business is registered.

Contractor forms. A business generally files Form 1099-NEC for a contractor it paid $2,000 or more for services during the year, for payments made in this page's tax year. Earlier years use $600 (IRS). The forms are due January 31 after the payment year (IRS due dates); for payments in this page's tax year the date is February 1, 2027. Not every payee gets a Form 1099-NEC: payments to a corporation are generally left off, with legal fees a main exception, and card and payment-network payments are reported by the processor on Form 1099-K (IRS instructions). See which contractors get a tax form.

Tax IDs and withholding. For a US payee, the payer generally collects the name and taxpayer identification number on Form W-9. A missing or incorrect number can require backup withholding (IRS). The payer deposits what it withholds and reports it on Form 945, and a payer that fails to withhold may owe the uncollected amount (requester instructions); see collecting tax IDs from contractors. Foreign contractors need different forms and may have different withholding rules: see paying contractors abroad.

Filing method. 10 or more information returns, Forms 1099 and W-2 combined, generally must be filed electronically (IRS). The quote should say whether that filing is included.

Whether the monthly fee covers collecting the W-9s, totaling the payments, any withholding and the filing is a scope question. For a contractor who may really be an employee, see contractors who may be employees.

Sales tax. Sales tax imposed on the buyer, which the business collects and pays over to the state, is not income, and the IRS's sample records subtract it from receipts. Tax imposed on the seller and recovered from the customer is part of gross receipts (Publication 334), so the books must show which kind applies. Each state then sets its own return schedule, and each additional state adds returns and due dates to the month. Whether you must collect in a state is a separate question: see when you must collect sales tax and filing sales tax returns.

Is catch-up work part of the monthly fee?

Only if the quote says so. Catch-up means recording months that were never booked, and a monthly fee is built around the current month's accounts and transactions. The IRS requires records that support the return (Publication 583), so unbooked months have to be rebuilt before the books can be relied on.

A quote that mixes the two should state:

• The first month covered, and the opening balances it starts from.
• Whether the backlog is a one-time charge or spread into the monthly fee, and the month the fee changes.
• Whether the late returns for those months are in or out, and who prepares and signs them.

For what drives the cleanup price, see catch-up bookkeeping cost.

Am I paying too much? What must a quote say to be comparable?

Two quotes are hard to compare unless they list the same work. A lower number with a narrower scope is not necessarily cheaper than a higher number that covers more.

Put every quote on one basis. Ask each firm to price the same list of work for the same period, then compare the totals, including the payroll, sales tax and contractor forms the business needs, whether bundled or billed separately. Show one-time catch-up charges apart. For an hourly quote, use the estimated hours and the stated cap. Keep a fixed fee as a fixed fee: a split into hours or per-transaction prices the firm did not give is made up. A fee that cannot be matched to a defined scope is hard to judge.

Treat a quote as hard to judge when:

• It says "bookkeeping" and a number, with no list.
• It is silent on payroll, sales tax or 1099 work, so you cannot tell whether they are excluded.
• A flat price was set before anyone saw a statement.
• Any part of the fee depends on a refund or on tax savings.

If the fee went up, ask for the change in writing and match it to the table's "What changes the price" line: a new account, volume above the quoted count, another state, another employee, or a backlog added to the monthly price. An increase with the same accounts, volume and duties is a reason to ask what changed.

For the written terms, see what a bookkeeping engagement letter should spell out and questions to ask before hiring a bookkeeper.

Hourly, flat or per transaction: what should I check in each?

Each basis puts the risk of more work in a different place, so check the term that decides who pays for it.

Can a bookkeeper or CPA charge a percentage of my refund or savings?

It depends on who the provider is and what the work is. For a CPA, enrolled agent or attorney, Treasury's Circular 230 bars unconscionable fees and, with exceptions, contingent fees for services in connection with any matter before the IRS.

The same section defines a contingent fee to include a fee based on a percentage of the refund reported on a return, a percentage of the taxes saved, or one that otherwise depends on the specific result attained. A matter before the IRS includes tax planning and advice, and preparing or filing returns or claims for refund or credit. The exceptions are narrow and mostly cover work after the IRS examines or challenges a return. One limit on the rule: in 2014 a federal district court in the District of Columbia held that the IRS lacks statutory authority to regulate fees for preparing and filing ordinary refund claims, meaning claims filed after the original return and before any examination (court opinion). That is one court's decision, and the regulation text is unchanged, so the text alone does not show how far the ruling reaches. Treasury has proposed to remove the section and treat a contingent fee for preparing an original or amended return or a refund claim as disreputable conduct; the proposal is not final (Internal Revenue Bulletin 2025-05). Put the question to the practitioner before signing. The IRS also tells taxpayers to avoid preparers who base their fees on a percentage of the refund.

The rule is written for practitioners: attorneys, certified public accountants, enrolled agents and certain other enrolled professionals (section 10.3). A bookkeeper who is also a CPA, enrolled agent or attorney is one. The text sets no fee rule for a person who only keeps books and holds none of those credentials. State accountancy board rules may add limits of their own: Treasury notes that many bar a contingent fee for preparing an original or amended return or a refund claim (same bulletin). Whatever the provider's credential, a fee tied to a refund or to savings is a reason to ask what result the fee depends on before signing.

What does a bookkeeper's wage tell me about price?

Very little. The Bureau of Labor Statistics median pay for bookkeeping, accounting and auditing clerks is $24.36 an hour: the wage at which half of workers in the job earned more and half less (BLS). It is what employers paid employees, not what a firm or an independent bookkeeper charges, and BLS publishes no firm rates.

Two limits:

• BLS says its pay data leave out self-employed workers, so independent bookkeepers are not in the figure.
• BLS says certification is not usually required for this job. The IRS list of credentials covers return preparation and representation, not keeping books.

BLS lists the core duties as entering transactions, producing balance sheets and income statements, checking accuracy and reconciling differences. A quote that looks high or low should be explainable against those duties and the extra items above. Ask who does the work, who reviews it and who could answer an IRS letter. To check a CPA, enrolled agent or attorney, use the preparer directory linked from the IRS page on choosing a tax professional.

When is doing my own books cheaper, and when does it cost more?

Doing your own books can be cheaper when the work is small and stays current. It can cost more when the work includes payroll, several states or a backlog, because mistakes there can carry penalties. In most cases the IRS allows any system that clearly shows income and expenses, and everyone in business must keep records whoever keeps them.

The comparison is the fee against your hours plus the cost of errors; the late-deposit penalty in the payroll section is one such cost. For the decision itself, see doing your own books or hiring a bookkeeper.

Example

These examples are illustrative. All amounts are US dollars.

Salon LLC with a US$1,000 quote

A salon LLC is quoted US$1,000 a month. The owner has two bank accounts, one card, payroll for four employees, and six contractors each paid US$3,000 in the year. The quote says "monthly bookkeeping" and lists nothing else. The US$1,000 is only a number in the story, not a typical price.

The owner asks the firm to answer line by line:

• Are all three accounts reconciled each month?
• Is payroll in: deposits, four Forms 941 a year, Form 940 and the W-2s? Or is it a separate line?
• Each contractor was paid more than the $2,000 reporting threshold, so a Form 1099-NEC may be due for each one who is not a corporation (an LLC taxed as a corporation counts as one). Who collects the W-9s and files?
• If all six need a Form 1099-NEC, those six plus the Forms W-2 for four employees make ten information returns, the count at which electronic filing is generally required. Does the quote include filing them electronically?
• Does any of this change the price?

A quote that lists no scope cannot be called fair or unfair until the firm answers these lines.

Online store with 800 orders

An online store has US$60,000 in sales a month from 800 orders. The platform report lists the orders, fees and refunds. The bank shows a smaller number of net payout deposits. Order volume, payout reports and inventory size the work, not the US$60,000. The quote should say which platform reports are reconciled, how fees and refunds are recorded, how stock is counted, and whether sales tax collected in other states is in or out. See ecommerce bookkeeper cost and scope.

Solo consultant with 40 transactions

A consultant has one business account, one card, about 40 transactions a month and no payroll. A quote built for a store with employees and sales tax may cover more than this business uses. The owner asks for a scope-based line list: two accounts reconciled monthly, about 40 transactions, an income statement and a balance sheet, with payroll, sales tax and contractor forms listed as not included. At this size, doing the books yourself may also be an option: see doing your own books or hiring a bookkeeper.
