Bookkeeping is recording every financial transaction your business makes, in categories, so you can produce accurate financial statements and tax returns. Accounting is interpreting those records. You can do the bookkeeping yourself; most owners benefit from a professional for tax returns and planning.
The five building blocks
Every transaction affects at least one of these five account types:
| Type | What it is | Examples |
|---|---|---|
| Assets | What the business owns | Cash, accounts receivable, equipment, vehicles, inventory |
| Liabilities | What the business owes | Credit card balances, loans, sales tax collected but not yet paid, accounts payable |
| Equity | The owner's stake | Owner contributions, owner draws, retained earnings |
| Income (revenue) | Money earned from customers | Service income, product sales |
| Expenses | Costs of running the business | Rent, fuel, software, wages, advertising |
The basic accounting equation ties them together: Assets = Liabilities + Equity. Profit (income minus expenses) increases equity; owner draws decrease it.
Why it matters beyond taxes
- Cash control: you see problems (a slow-paying client, a creeping expense) while you can still fix them.
- Pricing: you cannot price profitably without knowing your true costs.
- Lending: banks and SBA lenders ask for profit and loss statements and balance sheets.
- Liability protection: clean, separate books support your LLC's liability shield.
- Lower professional fees: a CPA who receives organized books spends fewer billable hours.
- Selling the business: buyers pay for documented profit.
How much time and money it takes
| Approach | Owner time per week | Typical cost (as of 2026, varies by region and volume) |
|---|---|---|
| DIY with software | 1–2 hours | Software roughly $0–$100/month |
| Part-time bookkeeper | 15–30 minutes (review and questions) | Often $200–$800/month for a small business |
| Bookkeeping plus tax service | 15 minutes | Often $300–$1,500+/month depending on complexity |
| Annual tax return preparation | — | Schedule C returns often a few hundred to around $1,000; partnership or S corporation returns often $1,000–$3,000+ |

Frequently asked questions
Can I do my own bookkeeping?
Many small business owners do their own bookkeeping with accounting software, especially in the early years. A simple monthly routine is usually enough. Many still use a tax professional for returns and planning.
When are quarterly estimated taxes due?
For individuals, federal estimated tax payments are generally due around April 15, June 15, September 15 and January 15 of the following year, adjusted when a date falls on a weekend or holiday. Check IRS.gov for current dates.
How long should I keep business records?
The IRS generally recommends keeping records that support items on a tax return for at least three years, and longer in certain situations, such as employment tax records or if income was underreported. Many owners keep records for seven years.
