Monthly bookkeeping costs for a small business in the United States depend on what you ask for. Owners often compare two quotes that look similar on paper and find out later that they cover very different work.
Pricing for this service depends on quantity, timing, and scope, so no single number works for every business. For current pricing, visit the Over The Moon Bookkeeping LLC website or request a quote after a short review of your books.
What Monthly Bookkeeping Services Usually Cost
Most monthly bookkeeping services are priced in one of three ways: a flat monthly fee, an hourly rate, or a fixed package. Each model can be fair, but they reward different kinds of clients. The ranges below reflect what small businesses commonly see in the market; they are benchmarks for comparison, not a quote for your specific books.
| Pricing Model | Typical Range | How It Works | Best For | Watch Out For |
|---|---|---|---|---|
| Hourly | $40-$100 per hour | Billed per hour of work | Very small, predictable volume | Costs rise with messy books or growth |
| Monthly flat fee | $200-$1,500 per month | Same amount each month for a defined scope | Steady, ongoing service | Confirm exactly what is included |
| Fixed-fee package | $300-$2,500 per month | Set price for defined services and tiers | Owners who want clear scope | Extra work may cost more |
A flat monthly fee is the easiest to budget. You pay the same amount every month, and the provider agrees to a defined scope of work. An hourly rate can look cheaper at first, yet costs climb quickly when the books are messy or transaction volume grows.
Sample Monthly Packages With Exact Inclusions
Broad ranges only help if you can see what sits inside them. Below are three illustrative tiers built around the most common scope drivers, transaction volume, account count, reconciliation, and reporting.
| Tier | Typical Monthly Price | Transaction Limit | Accounts Covered | Reconciliation | Reporting | Excluded (Billed Separately) |
|---|---|---|---|---|---|---|
| Starter / Basic | $200-$450 | Up to ~150 transactions | 1 bank + 1 credit card | Monthly | P&L and balance sheet | Payroll, sales tax, cleanup, advisory |
| Growth / Standard | $450-$900 | Up to ~400 transactions | Up to 3 accounts | Monthly, with review | P&L, balance sheet, cash flow | Payroll, sales tax filing, cleanup |
| Full-Service | $900-$2,500+ | 400+ transactions | 4+ accounts, multiple platforms | Weekly or as needed | Full reporting pack + check-in | Advisory projects, audit support |
When a quote lands below the Starter range, ask what is excluded. A low headline number usually means reconciliation, payroll, or sales tax work is priced separately, and those add-ons can double the effective monthly cost.
What Drives the Price Up or Down
The same business can receive quotes that differ because providers assume different inputs. The biggest levers are:
- Transaction volume: More bank and card activity means more time to categorize and reconcile.
- Number of accounts: Each bank account, credit card, loan, or payment platform adds work. A second business checking account is not free to reconcile.
- Business complexity: Multiple locations, inventory, or contractor payments raise the workload and the reporting burden.
- Software: Setup and ongoing support in QuickBooks Online or another platform can be a separate line item, often $50-$150 per month on top of the bookkeeping fee.
Total Cost of Ownership, Not Just the Headline Fee
The number on the proposal is rarely the full monthly cost. A realistic budget adds the recurring extras:
- Bookkeeping software subscription (if not bundled)
- Payroll processing, which may carry monthly and per-employee fees
- Sales tax tracking or filing, which may carry recurring fees
- Advisory or check-in meetings, which may be billed per session
Ask every provider for an all-in monthly estimate that includes the add-ons you actually need, and compare that figure rather than the headline.
Compare quotes on total monthly cost for your real transaction and account counts, not on the lowest advertised fee. A $300 quote that excludes payroll and sales tax can cost more than a $600 quote that includes them.
Watch out: a low monthly number can hide the real cost, so check whether reconciliation, payroll, or sales tax work is included.
What Is Included in Monthly Bookkeeping
Monthly bookkeeping is the routine upkeep of your financial records. A complete monthly service usually covers:
- Categorizing bank and credit card transactions
- Reconciling bank and credit card accounts to statements
- Tracking accounts payable and accounts receivable
- Keeping records organized for tax preparation (Recordkeeping)
Some providers also include payroll processing, sales tax tracking, or bookkeeping software setup. Others treat those as add-ons. Always ask which items are part of the base price.
Basic Versus Full-Service Packages
Packages generally fall into two levels:
- Basic bookkeeping: Transaction categorization and account reconciliation, with monthly reports delivered on a set schedule.
- Full-service bookkeeping: Everything in basic, plus financial reporting review, payroll coordination, sales tax support, and a regular check-in on cash flow.
Full service fits owners who want their numbers reviewed, not just recorded. A basic package fits owners with simple finances who mainly need clean records.
Small Business Bookkeeping Cost Per Month: Key Cost Drivers
Several factors move the monthly price up or down. The biggest ones are:
- Transaction volume: More bank and card activity means more time to categorize and reconcile.
- Number of accounts: Each bank account, credit card, loan, or payment platform adds work.
- Business complexity: Multiple locations, inventory, or contractors raise the workload.
- Software: Setup and ongoing support in QuickBooks Online or another platform can be a separate line item.
- Payroll and sales tax: Both add recurring tasks with compliance deadlines.
A common mistake is comparing quotes without first counting your accounts and monthly transactions. Two quotes for the same service can differ widely simply because one provider assumed fewer transactions.
Pricing Models: Hourly, Monthly Flat Fee, and Fixed-Fee Packages
Here is how the three main models compare:
| Pricing Model | How It Works | Best For | Watch Out For |
|---|---|---|---|
| Hourly | Billed per hour of work | Very small, predictable volume | Costs rise with messy books |
| Monthly flat fee | Same amount each month | Steady, ongoing service | Confirm exactly what is included |
| Fixed-fee package | Set price for defined services | Owners who want clear scope | Extra work may cost more |
Ask every provider which model they use and what triggers an extra charge. A clear answer is a good sign.
Bookkeeping Cleanup Cost: Catch-Up Work Before Monthly Service Begins
Many owners start with a backlog. If months of transactions are uncategorized or unreconciled, a provider usually needs to clean up the books before monthly service can run smoothly. This catch-up work is often billed separately from the ongoing monthly fee.
Cleanup pricing depends on how far behind the books are and how many accounts need work. Plan for this one-time cost in your budget.
Bookkeeping Services Pricing Template and Quote-Comparison Checklist
Most quote comparisons fail because owners compare headline fees instead of scope. The checklist below is built to fix that: it captures what each provider includes, what they charge extra for, and how they perform on the service-quality measures that determine whether the relationship works after month one.
The Comparison Template
Copy this table once per provider and fill in every row. Blank answers are gaps worth asking about before you sign.
| Item | What to Record | Why It Matters |
|---|---|---|
| Pricing model | Flat, hourly, or package | Determines how costs behave as you grow |
| Base monthly fee | Dollar amount | The headline number, not the full cost |
| Transaction limit | Number included before overage | The most common source of surprise charges |
| Accounts covered | Bank, credit card, loan, payment platforms | Each account adds reconciliation work |
| Reconciliation frequency | Monthly, weekly, as needed | Drives accuracy and close speed |
| Reporting package | Which statements, delivered when | Defines what you can actually review |
| Close timeline | Business days after month-end | A key service-quality measure |
| Payroll | Included or extra; per-employee fees | Often the largest add-on |
| Sales tax | Included or extra; filing included? | Compliance deadlines make this non-optional |
| Software | Included, extra, or client-provided | Recurring cost, if billed separately |
| Cleanup / catch-up | One-time fee and scope | Can be the largest single invoice |
| Advisory / check-ins | Included or extra; frequency | Separates record-keeping from review |
| Overage and extra-work billing | Rate and approval process | Prevents invoice surprises |
| Response time | Stated turnaround for questions | Predicts day-to-day experience |
| All-in monthly estimate | Base + add-ons you need | The number to actually compare |
How to Score and Compare
A filled-in table is only useful if you can rank the options. Use a simple weighted score:
- Total cost of ownership (40%): Use the all-in monthly estimate, not the base fee. Add cleanup as a first-year cost.
- Scope fit (30%): Does the package cover your actual transaction volume, accounts, payroll, and sales tax needs without overage?
- Service quality (20%): Close timeline, reconciliation frequency, reporting cadence, and stated response time.
- Transparency (10%): Clear answers on overage billing, add-on pricing, and what is excluded.
Score each provider 1-5 on each category, multiply by the weight, and add the results. The highest total is not automatically the winner, but a provider that scores well on transparency and scope fit is usually the safer long-term choice than the cheapest headline fee.
A quote with no stated transaction limit, no close timeline, and no overage policy is not a comparable quote. Ask for those three items in writing before you rank any provider.
Questions That Reveal the Real Price
- What happens if my transaction count doubles, how is overage billed?
- Is reconciliation included every month, and how quickly after month-end are books closed?
- Are payroll and sales tax filing included, or billed per run or per filing?
- Is software included, or do I pay the subscription separately?
- What did cleanup cost the last client with books similar to mine?
A simple way to use the list: write each provider’s answer next to every line. Blank answers signal gaps you should ask about. Not sure whether you are ready to hand off this work? Our article, Five Signs You Are Ready to Outsource Bookkeeping, can help you decide.

Frequently Asked Questions
How much do monthly bookkeeping services cost?
Monthly bookkeeping fees depend on transaction volume, number of bank and credit card accounts, payroll needs, the state of your existing records, and how much reporting you want. Because Over The Moon Bookkeeping LLC has not published standard rates in this guide, the most accurate figure comes from a direct quote. Visit the website and book a free evaluation to receive a price based on your actual account setup and goals.
What is included in monthly bookkeeping services?
Typical monthly bookkeeping covers categorizing transactions, reconciling bank and credit card accounts, recording accounts payable and receivable, and preparing monthly financial statements. Some providers add payroll processing, sales tax support, or advisory time. Ask for a written scope of work that lists what is included and what is billed separately, so there are no surprises when the first invoice arrives.
Do bookkeepers charge extra for catch-up or cleanup work?
Usually, yes. Catch-up work on months or years of unreconciled QuickBooks Online data takes more time than routine monthly maintenance, so it is often quoted separately from the ongoing service fee. The cost depends on how many months are behind and how messy the records are. Once the books are clean, the monthly service is typically easier and less expensive to maintain.
What should I look for in a bookkeeping services pricing template?
A useful quote lists the monthly base fee, included services, add-on charges for payroll or tax support, the cleanup estimate if needed, and any setup fees. Compare each quote line by line rather than the total alone.
