Three statements describe a business: what it earned, what it owns and owes, and where the cash actually went.
They are arithmetically linked, which is more useful than it sounds. Profit has to reach retained earnings and cash movement has to reach the bank balance, so when the three disagree the books are simply not closed yet.
This covers what each statement shows, how to read it, how the three tie together, the difference the accounting basis makes, and the things none of them will tell you.
The three basic financial statements, the income statement, balance sheet, and cash flow statement, are the foundation of financial reporting. This guide explains each one with real-world example line items.
1. The Income Statement
The income statement (also called the P&L) covers a period of time and shows how revenue becomes net income.
| Line Item | Example ($) |
|---|---|
| Revenue | 500,000 |
| Cost of Goods Sold | (200,000) |
| Gross Profit | 300,000 |
| Gross Margin % | 60% |
| Salaries and Wages | (120,000) |
| Rent | (24,000) |
| Marketing | (30,000) |
| Other Operating Expenses | (16,000) |
| Total Operating Expenses | (190,000) |
| EBITDA | 110,000 |
| Depreciation and Amortisation | (10,000) |
| Operating Income (EBIT) | 100,000 |
| Interest Expense | (8,000) |
| Net Income Before Tax | 92,000 |
| Income Tax (25%) | (23,000) |
| Net Income | 69,000 |
The three are arithmetically linked, so when they disagree the books are not closed. The cause is almost always mundane: an unreconciled account, a journal in the wrong period, a transaction entered twice. Fix it before you read anything into the numbers.

The balance sheet is a snapshot at a date. Assets = Liabilities + Equity always.
Assets
| Current Assets | Example ($) |
|---|---|
| Cash and Cash Equivalents | 80,000 |
| Accounts Receivable | 60,000 |
| Inventory | 40,000 |
| Prepaid Expenses | 10,000 |
| Total Current Assets | 190,000 |
| Non-Current Assets | Example ($) |
|---|---|
| Property, Plant and Equipment (net) | 150,000 |
| Intangible Assets | 20,000 |
| Total Non-Current Assets | 170,000 |
| TOTAL ASSETS | 360,000 |
Liabilities and Equity
| Current Liabilities | Example ($) |
|---|---|
| Accounts Payable | 35,000 |
| Accrued Liabilities | 15,000 |
| Short-Term Debt | 20,000 |
| Total Current Liabilities | 70,000 |
| Long-Term Liabilities and Equity | Example ($) |
|---|---|
| Long-Term Debt | 100,000 |
| Total Liabilities | 170,000 |
| Paid-In Capital | 120,000 |
| Retained Earnings | 70,000 |
| Total Equity | 190,000 |
| TOTAL LIABILITIES AND EQUITY | 360,000 |
3. The Cash Flow Statement
The cash flow statement explains the change in cash during the period.
Operating Activities (Indirect Method)
| Item | Example ($) |
|---|---|
| Net Income | 69,000 |
| Add: Depreciation and Amortisation | 10,000 |
| Increase in Accounts Receivable | (15,000) |
| Increase in Inventory | (5,000) |
| Increase in Accounts Payable | 8,000 |
| Net Cash from Operating Activities | 67,000 |
Investing Activities
| Item | Example ($) |
|---|---|
| Purchase of Equipment | (30,000) |
| Net Cash from Investing Activities | (30,000) |
Financing Activities
| Item | Example ($) |
|---|---|
| Repayment of Long-Term Debt | (20,000) |
| Net Cash from Financing Activities | (20,000) |
| Net Increase in Cash | 17,000 |
| Opening Cash Balance | 63,000 |
| Closing Cash Balance | 80,000 |
How the Three Statements Connect
The three are not separate reports that happen to sit together. They are three views of the same transactions, which is why a figure that moves in one has to surface in the others. The example figures above are linked at four points.
- Net income from the income statement flows into retained earnings on the balance sheet, which is why retained earnings accumulate from one period to the next rather than describing a single year
- Depreciation and amortisation is an expense on the income statement but no cash leaves the business, so it is added back in the operating section of the cash flow statement
- An increase in accounts receivable on the balance sheet reduces operating cash flow, because the revenue has been recognised but not yet collected
- Capital expenditure in the investing section of the cash flow statement increases property, plant and equipment on the balance sheet
If the income statement shows a profit while operating cash flow is negative for several months running, look at receivable collection and inventory levels before anything else. A profitable business that cannot collect is the most common way a set of books reads as healthy while the bank balance falls.
GAAP vs Cash Basis
GAAP (Generally Accepted Accounting Principles) requires accrual accounting, revenue recognised when earned, expenses when incurred. Cash basis records events only when cash moves. GAAP financial statements are required for audited reports, bank covenants, and investor reporting.
What the Statements Will Not Tell You
The three statements describe what happened to the money. They are close to silent on the things most likely to end a business, and knowing where that silence falls is part of reading them properly.
Concentration is the first blind spot. A revenue line of the same size reads identically whether it came from two hundred customers or from two, and the second is a materially different business. The same is true on the supply side, where a single source for a critical input is a risk that appears nowhere on the face of the accounts. Neither shows up until the year it matters, and then it shows up all at once.
Commitment is the second. The balance sheet records what you owe, not what you have promised: a lease with years left to run, a contract with a notice period, a renewal that is about to reprice, an order book that is either full or empty. The third is people. The accounts do not say that one person holds every customer relationship or that only one person can operate the production system, and that is often the largest single risk in a small company.
- Keep a short list of customers by share of revenue alongside the accounts, and read the two together
- Track the order book or forward bookings separately, since the income statement is entirely backward looking
- Note the renewal and notice dates on anything you cannot quickly replace
- Write down what would happen if each key person were unavailable for a month, because nothing in the statements will tell you

Frequently Asked Questions
What is EBITDA and why does it appear on the income statement?
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortisation) is a proxy for operating cash generation. It is not a GAAP line item but is widely used in valuation and lending covenants.
Why do assets always equal liabilities plus equity?
This is the accounting equation. Every asset is financed either by a creditor (liability) or by an owner (equity). If the balance sheet does not balance, there is a recording error.
How do retained earnings connect the income statement and balance sheet?
Net income increases retained earnings each period. Dividends decrease retained earnings. Retained earnings accumulate from inception of the business.
Which statement should I look at first each month?
The cash flow statement, then the income statement, then the balance sheet. Cash is the one that ends the business if it runs out, so it gets read first even in a profitable month. The income statement tells you whether the month worked, and the balance sheet is where you check that the story the other two tell is actually true: unexplained movements in receivables, stock or director loans usually surface there first.
What does it mean if the three statements do not agree?
It means the books are not closed, and it is a signal rather than a nuisance. The three are arithmetically linked, so profit has to reach retained earnings and the cash movement has to reach the bank balance. When they disagree the cause is almost always mundane: an unreconciled bank account, a journal posted to the wrong period, or a transaction entered twice. Fix it before you read anything into the numbers.
How often should I review financial statements?
Monthly at minimum. Review the income statement and cash flow statement monthly, and the balance sheet quarterly. If you are raising capital or applying for a loan, you will need year-end statements prepared on an accrual basis.
Who outside the business will ask to see these?
Lenders, landlords, insurers, prospective buyers and, at some point, a tax authority. Each wants something different: a lender is reading the cash flow and the debt on the balance sheet, a buyer is reading the earnings and how repeatable they are. The practical consequence is that statements produced only for your own use still need to be defensible, because the day someone asks is rarely the day you have time to rebuild them.
Do these have to be prepared by an accountant to be valid?
No. Statements you produce yourself from your own books are perfectly valid for managing the business, and most small companies run on exactly that. What changes is who will rely on them. A bank or an investor will usually want them prepared or reviewed by someone independent, and the further up that scale you go, the more the standard of preparation matters rather than the numbers themselves.
