Frequently asked questions

Bookkeeping basics

What does a bookkeeper do for a small business?

A bookkeeper records your day-to-day financial transactions, reconciles your bank and credit card accounts, categorizes expenses, and keeps your books accurate and up to date. This gives you a clear picture of where your money is going and makes tax time much simpler.

When should I hire a bookkeeper?

If you are spending hours each week on your own books, falling behind on reconciliations, or dreading tax season because your records are a mess, it is time to bring in a bookkeeper. Most small business owners benefit from professional bookkeeping once they have regular income and expenses flowing through the business.

Do I need a bookkeeper if I already have a CPA?

Yes. A CPA typically handles tax preparation and high-level financial advice, but they rely on accurate books to do that work. A bookkeeper keeps your records current throughout the year so your CPA has clean data to work with when tax season arrives.

What is the difference between a bookkeeper and an accountant?

A bookkeeper handles the daily recording and categorization of transactions, bank reconciliations, and ongoing maintenance of your financial records. An accountant or CPA focuses on tax preparation, financial analysis, and strategic advice. Many small businesses need both — a bookkeeper to maintain the books and a CPA to handle taxes and planning.

Can I do my own bookkeeping, or do I need a professional?

You can do your own bookkeeping if you have the time and discipline to stay on top of it. In practice, most small business owners fall behind within a few months because running the business takes priority. If your books are already behind or you are unsure how to categorize transactions correctly, a professional bookkeeper will save you time and prevent costly errors.

How often should I update my books?

At minimum, update your books monthly. Weekly is better if you have a high volume of transactions. The longer you wait, the harder it is to remember what transactions were for, and the more likely errors will pile up.

What is cash vs accrual accounting and which should I use?

Cash accounting records income when you receive payment and expenses when you pay them. Accrual accounting records income when you earn it and expenses when you incur them, regardless of when money changes hands. Most small businesses start with cash accounting because it is simpler. If your business carries inventory or has significant accounts receivable, accrual may give you a more accurate financial picture. Your accountant can advise on which method fits your situation.

What bookkeeping records do I need to keep?

Keep bank and credit card statements, receipts for business expenses, invoices you send and receive, payroll records, tax returns, and any contracts or loan documents. The IRS generally recommends keeping records for at least three years, and up to seven years for certain items.

Cleanup and catch-up services

How much do bookkeeping cleanup services typically cost?

Cost depends on how far behind your books are and how complex your transactions are. A few months of catch-up for a straightforward business costs less than years of neglected books with multiple accounts. We provide a quote after reviewing your current situation so you know the cost before we start.

What is the difference between bookkeeping cleanup and catch-up?

Cleanup means fixing errors, miscategorizations, and discrepancies in books that were being maintained but have problems. Catch-up means bringing books current when they have not been touched for weeks or months. Many businesses need a combination of both.

How long does a bookkeeping cleanup take?

A few months of catch-up work can often be completed in one to two weeks. If your books have not been touched in over a year or have significant errors, it may take longer. We give you a timeline estimate after the initial review.

What is the first step in bookkeeping cleanup?

The first step is a review of your current books to identify what is wrong — missing transactions, incorrect categories, unreconciled accounts, duplicate entries. That review tells us the scope of the cleanup and lets us give you an accurate quote and timeline.

What are the signs I need a bookkeeping cleanup?

Common signs include: your bank balance does not match what your books show, you have transactions sitting in "uncategorized" or "ask my accountant," your balance sheet has negative numbers that should not be there, you cannot produce a profit and loss report you trust, or your tax preparer has told you the books need work before they can file.

Can I clean up my QuickBooks file myself?

You can tackle simple issues like recategorizing a few transactions or clearing out duplicates. But if your accounts are not reconciling, your balance sheet is off, or you are not sure where the errors are, a professional cleanup is usually faster and more reliable. Fixing books incorrectly can create bigger problems down the line.

What should I do if my books are several months behind?

Gather your bank and credit card statements for the months you have missed. If you use QuickBooks, connect your bank feeds so the transactions can be downloaded. Then either work through them systematically yourself or bring in a bookkeeper to catch you up. The longer you wait, the harder the catch-up becomes.

What should I do if I have several months of unfiled bookkeeping?

Start by collecting all your bank statements, credit card statements, and any receipts you have for the missing period. This gives your bookkeeper the raw data needed to reconstruct your records. Do not try to guess or estimate — work from the actual statements.

What is the step-by-step process for a DIY QuickBooks cleanup?

Start by reconciling your bank accounts one month at a time, beginning with the oldest unreconciled month. Then review and fix categorization errors in your transactions. Next, clear out any duplicate transactions. After that, review your accounts receivable and accounts payable for accuracy. Finally, run a balance sheet and profit and loss report to check that the numbers look right. If you get stuck at any step, that is a good time to call a professional.

What should I look for in a QuickBooks cleanup service?

Look for someone who will start with a review of your current file before quoting a price, who explains what they find in plain language, and who delivers reconciled books you can verify against your bank statements. Ask whether the cleanup includes fixing your chart of accounts and whether they will walk you through the results when finished.

Monthly bookkeeping rhythm

What bookkeeping tasks should I do every month?

Reconcile all bank and credit card accounts, review and categorize any uncategorized transactions, send overdue invoice reminders, review your profit and loss statement, and check your cash flow. Monthly reconciliation is the single most important habit — it catches errors early.

What bookkeeping tasks should I do every quarter?

Review your profit and loss statement and balance sheet for the quarter. Compare actual results to your budget if you have one. Make sure sales tax filings are current. If you pay estimated taxes, calculate and submit your quarterly payment. This is also a good time to review your chart of accounts for categories you are no longer using.

What bookkeeping tasks should I do at year-end?

Reconcile all accounts through December 31. Review your annual profit and loss and balance sheet. Gather all documents your tax preparer will need (1099s, W-2s, receipts for major deductions). Verify that all vendor payments over $600 are documented for 1099 reporting. Back up your QuickBooks file. This is also the time to review the prior year and set a budget for the new one.

Why should I reconcile my bank accounts every month?

Reconciliation catches errors — duplicate charges, missing deposits, unauthorized transactions, and miscategorized expenses. If you wait months between reconciliations, a small error can compound into a much bigger problem. Monthly reconciliation also means your financial reports are accurate when you need them.

How do I avoid common bookkeeping mistakes?

Reconcile monthly without exception. Keep business and personal finances completely separate. Categorize transactions as they happen rather than in bulk at the end of the quarter. Review your books regularly instead of only at tax time. And ask for help when something does not look right — a small question now prevents a big cleanup later.

What is the best way to keep my books tax-ready year round?

Reconcile every month, categorize every transaction, and save receipts for any expense over $75 (or any expense your tax preparer might question). If you do these three things consistently, tax season is a handoff instead of a scramble.

QuickBooks specifics

What is a chart of accounts?

A chart of accounts is the list of categories your bookkeeping software uses to organize every transaction — income, expenses, assets, liabilities, and equity. Think of it as the filing system for your money. A well-organized chart of accounts makes your financial reports useful. A messy one makes them confusing.

How do I fix duplicate transactions in QuickBooks?

Go to your bank feed and look for transactions that appear both as manually entered records and as downloaded bank feed entries. QuickBooks will sometimes match them automatically, but when it does not, you need to manually match or delete the duplicate. Always reconcile after cleaning up duplicates to make sure your balance is correct.

How do I handle missing transactions in my books?

Check your bank and credit card statements for the period in question and compare them to what is recorded in your books. Any transaction on the statement but not in your books needs to be entered manually. If you use bank feeds, check whether the connection was interrupted — missing transactions often result from a temporary disconnect.

What are accounts payable and accounts receivable?

Accounts receivable is money your clients owe you for work you have already done. Accounts payable is money you owe your vendors for goods or services you have received. Tracking both gives you an accurate picture of your cash flow — not just what is in the bank today, but what is coming in and going out.

Why is my balance sheet out of balance?

A balance sheet that does not balance usually means there are unreconciled transactions, journal entries with errors, or transactions posted to incorrect accounts. The most common cause in QuickBooks is opening balances that were set up incorrectly or transactions that were entered without a proper offsetting entry. A cleanup review can identify the source.

How do I review my profit and loss report?

Run the report for the period you want to review (monthly or quarterly). Look at total income first, then total expenses, then net profit. Compare to the prior period to spot anything unusual — a category that jumped significantly or income that dropped. Check for transactions in "uncategorized" or "ask my accountant" and reclassify them. The report is only as useful as the data behind it.

What is a cash flow report and why is it important?

A cash flow report shows money actually moving in and out of your business during a period. It differs from a profit and loss statement because it accounts for the timing of payments, not just when income was earned or expenses incurred. A business can be profitable on paper but still run out of cash if receivables are slow and payables are due now. The cash flow report shows you that gap.

Why don't my bank deposits match my income in QuickBooks?

Several things can cause this. If you use accrual accounting, income is recorded when invoiced, not when the payment lands in the bank. Deposits that combine multiple payments into one lump sum will not match individual invoice payments. Sales tax collected and deposited alongside revenue can inflate the deposit amount. And sometimes transactions are simply miscategorized. Reconciling monthly is the best way to catch and resolve these differences.

How do I track unpaid invoices?

In QuickBooks, run an Accounts Receivable Aging report. This shows every outstanding invoice, how long it has been unpaid, and the total amount owed to you. Review this report weekly or at least monthly, and follow up on anything past 30 days. Consistent follow-up on receivables is one of the simplest ways to improve cash flow.

How do I track unpaid bills?

Run an Accounts Payable Aging report in QuickBooks. This shows every bill you have entered but not yet paid, organized by vendor and how long it has been outstanding. Use this report to plan your payments and avoid late fees or missed vendor discounts.

Record keeping and expenses

What expenses can I track as a business owner?

Any ordinary and necessary expense related to running your business can be tracked. Common categories include office supplies, software subscriptions, professional services (legal, accounting), marketing, travel, meals (with business purpose documented), insurance, rent, and utilities. If you are unsure whether something qualifies, ask your bookkeeper or tax preparer.

How do I categorize expenses correctly?

Use your chart of accounts as the guide. Each expense should go into the category that most accurately describes what it was for. Be consistent — if you categorize software subscriptions under "Software" in January, do not switch to "Office Expenses" in March. When in doubt, check the IRS Schedule C categories for sole proprietors or ask your bookkeeper which category applies.

How do I separate personal and business finances?

Open a dedicated business bank account and business credit card. Run all business income and expenses through those accounts and nothing personal. Do not pay personal bills from the business account or deposit business income into your personal account. Clean separation makes bookkeeping faster, tax preparation simpler, and protects your limited liability if you operate as an LLC or corporation.

How do I track cash flow in my business?

Start with your cash flow report in QuickBooks, which shows money moving in and out over a period. Beyond the report, get in the habit of reviewing your bank balance against your upcoming obligations weekly. Know what invoices are outstanding (money coming in) and what bills are due (money going out). If you regularly run tight on cash despite being profitable, the issue is almost always timing — and the cash flow report will show you where.

What deductions can I legally claim?

You can deduct ordinary and necessary business expenses — things like rent, utilities, insurance, supplies, professional services, marketing, travel, and employee wages. The key test is whether the expense is both common in your industry and helpful to your business. Keep receipts and documentation for every deduction. Your tax preparer can identify deductions specific to your industry and situation.

What expenses are not deductible?

Personal expenses, fines and penalties, political contributions, and most entertainment expenses are not deductible. Clothing is generally not deductible unless it is a uniform or required safety gear. Commuting costs between your home and your regular place of business are not deductible. When in doubt, ask your tax preparer before claiming a deduction.

Can I write off my home office, car, or phone?

Yes, but with conditions. A home office deduction requires a dedicated space used regularly and exclusively for business. Vehicle expenses can be deducted for business use (not commuting) using either actual expenses or the standard mileage rate. A phone used for both personal and business can be partially deducted based on the percentage of business use. Keep a log or records showing the business use for each.

What is the best bookkeeping software for small businesses?

QuickBooks Online is the most widely used option and works well for most small businesses. It integrates with banks, payment processors, and most tax preparation software. Other solid options include Xero and FreshBooks. The best choice depends on your business size, industry, and what features you need. See our bookkeeping software recommendations section below for more detail.

Tax prep and planning

What is the best way to prepare for tax season?

Keep your books current throughout the year. Reconcile monthly, categorize every transaction, and save receipts. Before your filing deadline, gather all 1099s and W-2s, confirm your profit and loss and balance sheet are accurate, and organize any documentation your tax preparer has requested. Businesses that keep clean books year round spend a fraction of the time on tax prep compared to those scrambling to catch up in March.

What documents should I give my tax preparer?

At minimum: your profit and loss statement for the year, your balance sheet, all 1099 forms received and sent, W-2s for employees, bank and credit card statements (or access to your QuickBooks file), receipts for major deductions, and records of estimated tax payments made during the year. If you had significant asset purchases, provide those records too.

Do I need to pay quarterly estimated taxes?

If you expect to owe $1,000 or more in federal taxes for the year, the IRS generally requires quarterly estimated payments. This applies to most self-employed individuals and business owners. Missing quarterly payments can result in penalties and interest, even if you pay the full amount by the filing deadline.

How much should I set aside for taxes?

A common starting point is 25-30% of your net profit, but the right number depends on your tax bracket, state taxes, deductions, and entity type. Your tax preparer can give you a more precise percentage based on your specific situation. Set this money aside in a separate account as you earn it so it is available when quarterly payments are due.

What happens if I don't pay quarterly estimated taxes?

The IRS charges an underpayment penalty plus interest on the amount you should have paid. The penalty is calculated quarter by quarter, so even paying late for one quarter triggers it. State tax agencies often impose their own penalties as well. The penalty is avoidable — it just requires planning your payments in advance.

How do I calculate my estimated tax payments?

Take your expected annual net profit, apply your effective tax rate (federal plus state plus self-employment tax if applicable), and divide by four. You can base the estimate on last year's tax liability or this year's projected income. IRS Form 1040-ES includes a worksheet to walk through the calculation. Your tax preparer can help you set up the right amount for each quarter.

How do I lower my tax bill legally?

Maximize your deductions by tracking every legitimate business expense. Contribute to retirement accounts (SEP IRA, Solo 401k) which reduce taxable income. Consider your entity structure — an S Corp election can reduce self-employment tax for some businesses. Time large purchases or expenses strategically. Work with a tax professional to identify opportunities specific to your situation.

Should I file as an LLC, S Corp, or sole proprietor?

Each structure has different tax implications. A sole proprietor pays self-employment tax on all net profit. An LLC taxed as a sole proprietor works the same way but offers liability protection. An S Corp election can reduce self-employment tax by allowing you to split income between a reasonable salary and distributions. The right structure depends on your income level, growth plans, and whether the administrative costs of an S Corp are worth the tax savings. A tax professional can model the numbers for your specific situation.

When should I elect S Corp status?

The general rule of thumb is when your net business profit is consistently above $40,000-$50,000 per year and the tax savings from the salary/distribution split outweigh the added costs of payroll processing and additional tax filings. Election timing matters — you typically need to file IRS Form 2553 by March 15 of the tax year. Talk to your tax preparer before making this election.

What forms do I need to file as a small business owner?

It depends on your entity type. Sole proprietors file Schedule C with their personal 1040. S Corps file Form 1120-S. Partnerships file Form 1065. All businesses with employees file payroll tax returns (940, 941). If you paid contractors over $600, you file 1099-NEC forms. State filings vary. Your tax preparer will know which forms apply to your specific situation.

What is the deadline for business taxes?

Sole proprietors and single-member LLCs file by April 15 (with their personal return). S Corps and partnerships file by March 15. C Corps file by April 15. Extensions are available — six months for personal returns, five months for S Corps and partnerships — but an extension to file is not an extension to pay. Estimated taxes owed are still due by the original deadline.

Should I hire a tax professional or do my own taxes?

If your tax situation is straightforward — single income source, few deductions, no employees — you can likely handle it yourself with tax software. Once you have a business with multiple income streams, employees or contractors, significant deductions, or questions about entity structure, a tax professional will typically save you more than they cost. They also reduce your audit risk by filing correctly the first time.

What triggers an IRS audit?

Common triggers include unusually high deductions relative to your income, reporting zero or near-zero net income for multiple years, large cash transactions, mismatches between what you report and what third parties report (1099s, W-2s), and home office deductions. Random selection also accounts for some audits. The best protection is accurate books and documentation for every number on your return.

How do I file taxes if I have multiple income streams?

Each income stream gets reported on the appropriate form — W-2 income on your 1040, business income on Schedule C (or your business return), rental income on Schedule E, investment income on Schedule D. Keep separate records for each income source. A tax professional is especially valuable when you have multiple streams, as the interactions between them can affect your overall tax strategy.

How do I prepare my books for tax season?

Reconcile all accounts through December 31. Review your profit and loss statement for any miscategorized transactions. Verify that all 1099-reportable payments are documented. Check that your balance sheet is accurate. Gather receipts for major deductions. Run your year-end reports and compare them to last year to catch anything that looks off. If your bookkeeper handles your monthly books, this should already be done — just confirm with them.

Bookkeeping and taxes together

Can bookkeeping cleanup help with my taxes?

Yes. If your books have errors or missing transactions, your tax return will reflect those problems — you may be overpaying, underpaying, or missing deductions entirely. A cleanup corrects the underlying data so your tax preparer works with accurate numbers. Some clients find that a cleanup pays for itself through recovered deductions.

How does bookkeeping affect my taxes?

Your tax return is built from your books. Every number on your profit and loss statement flows into your tax filing. If expenses are miscategorized, income is missing, or accounts are not reconciled, your tax return will be wrong. Good bookkeeping throughout the year means your tax return is accurate and you claim every deduction you are entitled to.

What happens if I use inaccurate bookkeeping for my taxes?

You risk underreporting income (which can trigger penalties and interest), missing legitimate deductions (which means overpaying), or filing an inconsistent return that raises audit flags. If the IRS audits you and your books do not support your return, the burden of proof is on you.

What happens if I file taxes with incorrect books?

If the errors are in your favor (you underpaid), you may owe additional tax plus penalties and interest if the IRS catches it. If the errors are against you (you overpaid), you left money on the table. Either way, filing an amended return to correct material errors is usually the right move. The sooner you correct it, the smaller the penalties.

How do I fix errors after filing my taxes?

File an amended return using IRS Form 1040-X (for personal returns) or the appropriate amended form for your business entity. You generally have three years from the original filing date to amend. Include documentation supporting the corrections. If the amendment results in additional tax owed, pay it with the amendment to minimize interest.

Should I amend my tax return if my books change after filing?

If the changes are material — meaning they significantly affect your taxable income or the tax owed — yes, you should file an amended return. Small reclassifications that do not change the bottom line usually do not require an amendment. When in doubt, ask your tax preparer whether the change is significant enough to warrant filing.

What happens if my books don't match my tax return?

This is a problem that should be resolved. Common causes include timing differences (especially with accrual accounting), adjustments your tax preparer made that were not recorded back to your books, or errors in either the books or the return. Reconcile your books to your tax return after filing each year. If they do not match, figure out why and correct whichever record is wrong.

Can poor bookkeeping reduce my refund or increase what I owe?

Absolutely. If expenses are not recorded or are miscategorized, you lose deductions. If income is double-counted or incorrectly classified, you overpay. Clean books ensure you pay exactly what you owe — no more, no less.

Can bookkeeping errors trigger tax problems?

Yes. Errors in your books flow directly into your tax return. Misclassified income, missing expenses, or unreconciled accounts can result in underreporting, over reporting, or inconsistencies that flag your return for review. Consistent, accurate bookkeeping is the simplest way to avoid tax problems.

How do I choose the right bookkeeping service?

Look for someone who specializes in small businesses in your industry or a related one. Ask whether they use QuickBooks (or your preferred software), how often they will reconcile your accounts, and what reports you will receive. Understand what is included in their monthly fee versus what costs extra. A good bookkeeper communicates clearly and explains your numbers in language you understand.

Book keeping software recommendations

What is the best bookkeeping software for a small business just starting out?

QuickBooks Online Simple Start or QuickBooks Online Essentials are the most common choices for new businesses. They handle invoicing, expense tracking, bank connections, and basic reporting. If your business is very small and you want something simpler, Wave is a free option that covers the basics. The right choice depends on how many transactions you process and whether you need features like inventory tracking or multiple users.

What is the difference between QuickBooks Online and QuickBooks Desktop?

QuickBooks Online is cloud-based — you access it from any browser, your data is backed up automatically, and it receives updates continuously. QuickBooks Desktop is installed on a single computer, offers more advanced reporting and inventory features, but requires manual backups and only receives periodic updates. Most small businesses are better served by QuickBooks Online for its accessibility and ease of use. Desktop is still preferred by some accountants and businesses with complex inventory needs.

Should I use QuickBooks or Xero?

Both are solid choices. QuickBooks has a larger user base in the US, which means more accountants and bookkeepers are familiar with it and more third-party apps integrate with it. Xero has a cleaner interface and unlimited users on all plans. If your bookkeeper or tax preparer has a preference, go with their recommendation — the software they know well will serve you better than the one they have to learn.

Do I need bookkeeping software, or can I use a spreadsheet?

You can use a spreadsheet for very simple businesses with few transactions. But spreadsheets do not reconcile with your bank, do not generate standard financial reports, and are prone to formula errors. Once you have more than a handful of transactions per month, bookkeeping software saves time, reduces errors, and gives you reports your tax preparer can actually use.

What features should I look for in bookkeeping software?

Bank and credit card connection (automatic transaction import), invoicing, expense categorization, financial reporting (profit and loss, balance sheet, cash flow), receipt capture, and the ability to share access with your bookkeeper or tax preparer. If you have employees, look for payroll integration. If you sell products, look for inventory tracking. Start with what you need now — most platforms let you upgrade as your business grows.
