TL;DR. A good monthly bookkeeping service categorizes every transaction, reconciles bank and credit card accounts, produces a reviewed P&L and balance sheet, tracks AR and AP where applicable, records payroll from your payroll provider, handles sales tax tracking, and preps books for tax time. It does not include tax return filing, tax planning, audit representation, or running payroll itself. Expect $200-500/month for a typical small business, with a dedicated bookkeeper you can reach.
You know you need a bookkeeper. Or at least you're pretty sure you do. But when you start looking into it, the descriptions are vague. "We'll handle your books." "Monthly bookkeeping services." "Full-service accounting support." What does that actually mean? What are you paying for?
We get this question a lot, and it's a fair one. Bookkeeping services vary wildly depending on who you hire. Some firms do the bare minimum. Others do everything short of filing your tax return. Here's what a good monthly bookkeeping service actually does, and what you should expect to receive.
Transaction categorization
This is the core of bookkeeping. Every transaction that flows through your business bank accounts and credit cards needs to be assigned to the right account in your chart of accounts. Revenue goes to revenue. Office supplies go to office supplies. That contractor payment goes to subcontractor expense, not "miscellaneous."
This sounds simple, but it's where most DIY bookkeeping falls apart. Transactions get miscategorized, duplicated, or left uncategorized entirely. Over the course of a year, these small errors compound into financial statements that don't reflect reality.
A bookkeeper reviews every transaction, applies consistent categorization rules, and handles the edge cases, split transactions, reimbursements, owner draws, transfers between accounts, that trip most people up.
Bank and credit card reconciliation
Reconciliation is the process of matching your accounting records to your actual bank and credit card statements. It's the single most important quality control step in bookkeeping, and it's the one most often skipped by business owners doing their own books.
Every month, your bookkeeper pulls your statements and compares them line by line against what's recorded in QuickBooks Online. They're looking for:
- Transactions in the bank that aren't in QBO (missed entries)
- Transactions in QBO that aren't in the bank (duplicates or errors)
- Amounts that don't match (typos, partial payments)
- The ending balance matching exactly
When reconciliation is done monthly, discrepancies are caught early and are easy to fix. When it's not done for months, you end up with a tangled mess that takes hours to sort out, the classic pattern behind every books-not-tax-ready scenario.
Financial statements
At the end of each month, you should receive at minimum two reports:
Profit & Loss (Income Statement): Shows your revenue, expenses, and net income for the period. This tells you whether your business made or lost money that month, and where the money went.
Balance Sheet: Shows your assets, liabilities, and equity at a point in time. This tells you what your business owns, what it owes, and what's left over. It's the report your CPA, lender, or investor will ask for first.
Some bookkeepers also provide a cash flow statement, accounts receivable aging, or accounts payable summary depending on your package. At bookkeepz, our Grow and Surge packages include enhanced reporting beyond the standard P&L and Balance Sheet.
The key thing: these reports should be accurate. If your bookkeeper is just running the default QBO reports without reviewing them for errors, the reports might look right but contain garbage data. A good bookkeeper reviews the statements before sending them to you and flags anything unusual. A live financial dashboard takes this one step further by surfacing the numbers continuously.
Accounts receivable and payable tracking
If your business sends invoices (accounts receivable) or receives bills from vendors (accounts payable), your bookkeeper should be tracking who owes you money and who you owe money to.
For AR, this means recording invoices, tracking payments received, and following up on overdue accounts. For AP, this means recording vendor bills, tracking due dates, and making sure nothing falls through the cracks.
Not every bookkeeping package includes AR/AP management. For our clients, it's included starting with the Grow package. If you're on a basic plan and your business has significant receivables or payables, it's worth upgrading for this alone, unpaid invoices and missed bills are among the most common cash flow killers for small businesses.
Payroll recording
Most small businesses use a payroll service, Gusto, ADP, Paychex, or similar. The payroll service handles the actual paychecks, withholding, and tax filings. But the transactions still need to be recorded in your books correctly.
Your bookkeeper makes sure payroll transactions are categorized properly: gross wages, employer taxes, employee withholding, retirement contributions, health insurance, each to the right account. At year-end, they verify that your books match your payroll service's reports and your W-2s.
This is especially important for S-Corp owners who need to track officer compensation separately for reasonable salary documentation.
Sales tax tracking
If your business collects sales tax, your bookkeeper should be tracking what you've collected and what you owe. Sales tax isn't income, it's a liability. You collected it on behalf of the state, and you owe it to the state.
Your bookkeeper records sales tax collected as a liability, tracks the amounts by jurisdiction if needed, and provides the numbers you need to file your sales tax returns. Some bookkeepers will file the returns for you; others provide the data and leave the filing to you or your CPA.
Year-end preparation
A good monthly bookkeeping service doesn't just keep your books clean during the year, it prepares them for tax season. This includes:
- Final reconciliation of all accounts for the tax year
- Review of the full-year P&L and Balance Sheet for accuracy
- Ensuring all 1099s have been issued to contractors
- Verifying payroll totals match W-2s
- Preparing any schedules your CPA needs (depreciation, loan amortization, etc.)
- Delivering a clean, reconciled set of books ready for tax preparation
When this is done right, your CPA can prepare your return quickly and accurately. When it's not, your CPA has to do the cleanup work first, and you pay for that time. See Tax Deductions Private Practice Owners Are Probably Missing for the specific categorizations that save money at tax time.
What you should NOT expect
Bookkeeping and accounting are related but different. A monthly bookkeeping service typically does not include:
- Tax return preparation and filing, that's your CPA's job (though we offer this as a separate service)
- Tax planning and strategy, requires CPA-level expertise
- Audit representation, you need a CPA or enrolled agent
- Financial forecasting, some bookkeepers offer this at higher tiers, but it's not standard
- Running payroll, your payroll service does this; your bookkeeper records it
The line between bookkeeping and accounting blurs at higher service tiers. Our Surge package, for example, includes CPA oversight and cash flow forecasting, but that's specifically because we've built those capabilities into the service.
How to evaluate what you're getting
When you're comparing bookkeeping services, ask these specific questions:
- Do you reconcile bank and credit card accounts every month?
- What financial reports do I receive, and how often?
- Do you review the reports before sending them, or just run them?
- How do you handle categorization questions, do you ask me, or make assumptions?
- What's included in year-end preparation?
- Do I get a dedicated bookkeeper, or a rotating team?
The answers tell you whether you're getting actual bookkeeping or just data entry. There's a big difference, and the price difference is usually smaller than you'd expect. For a deeper evaluation framework, read How to Choose a Bookkeeper for Your Private Practice.
What it looks like with bookkeepz
Every client gets a dedicated bookkeeper who handles all of the above, categorization, reconciliation, financial statements, and year-end prep, every single month. You get access to our client portal where you can upload documents, view reports, and communicate with your team.
Our packages start at $199/month for Starter, which covers the essentials. Grow adds enhanced reporting, AR/AP tracking, and quarterly review meetings. Surge adds CPA oversight, monthly reviews, and a live financial dashboard.
Key takeaways.
- Monthly bookkeeping = categorization + reconciliation + reviewed P&L and balance sheet + year-end prep.
- Expect a dedicated bookkeeper, not a rotating team, if you're paying for quality.
- Tax filing, tax planning, and audit representation are usually separate services, priced differently.
- Ask whether the bookkeeper reviews reports before sending or just exports QBO defaults. The difference matters.
- $200-500/month is the typical range for small businesses under $500K in revenue.
Common questions
What's included in a standard monthly bookkeeping package?
Transaction categorization, bank and credit card reconciliation, a monthly profit and loss statement, a balance sheet, and year-end preparation. Higher tiers add AR/AP tracking, payroll recording, sales tax tracking, cash flow statements, and quarterly or monthly review calls.
How long does monthly bookkeeping take a bookkeeper to do?
For a typical small business, your bookkeeper spends two to six hours per month. You might spend 30 minutes answering clarification questions. Complex businesses with multiple entities or high transaction volume scale up from there.
Is tax return preparation included with bookkeeping?
Usually not. Bookkeeping keeps your books tax-ready, but filing is a CPA service. Some firms offer both (bookkeepz does). When comparing prices, make sure you're comparing scope.
What financial reports should I expect every month?
Profit and Loss and Balance Sheet at minimum. Enhanced packages add cash flow statements, AR/AP aging summaries, and budget-vs-actual comparisons. Reports should be reviewed for accuracy, not just exported.
Do bookkeepers file my sales tax returns?
Depends on the package. Some firms track and file; others track and give you the data to file. Confirm this during onboarding. For multi-jurisdiction sales tax, filing services may cost extra.
Do monthly bookkeepers handle payroll?
They record payroll transactions from your payroll service (Gusto, ADP, Paychex); they usually do not run payroll themselves. Running payroll, processing paychecks, filing quarterly payroll tax returns, is a separate function handled by your payroll provider.
What's the difference between bookkeeping and accounting?
Bookkeeping records, categorizes, and reconciles transactions, and produces financial statements. Accounting interprets those statements for tax filing, strategic planning, and compliance. Most small businesses need both.
Will my bookkeeper catch mistakes I made earlier?
Yes. Monthly reconciliation and statement review typically surface prior-period errors, duplicate entries, miscategorized expenses, missed transactions. A good bookkeeper flags them and proposes corrections.
How often will I hear from my bookkeeper?
Monthly financial statements always. Mid-month clarification questions as they arise. Quarterly review calls on higher-tier packages. If you need to reach them ad hoc, response times should be same-day to 24-hour.
Do I need to send my bookkeeper bank statements?
If your accounts have live connections to QuickBooks, usually no. For accounts without a connection (some credit unions, PayPal, Square, merchant processors), expect to share monthly statements so your bookkeeper can reconcile.
What happens at year-end?
Final reconciliation of every account, a reviewed full-year P&L and Balance Sheet, 1099-NEC preparation for contractors paid $600 or more, W-2 verification for S-Corp officers, and prep schedules your CPA needs (depreciation, loan amortization, etc.).
Is there a long-term contract?
At bookkeepz, no. Monthly service, cancel anytime. Other firms vary, some require annual commitments. Always ask before signing.
