Reading Financial Statements
Three documents describe every business: the income statement (how the period went), the balance sheet (what the business owns and owes right now), and the cash-flow statement (where the money actually moved). The deeper lesson: they're one system, not three reports — profit on the income statement is an accounting opinion, cash on the cash-flow statement is a fact, and the balance sheet explains the gap between them.

What this topic is
The three core financial statements and how they interlock: the income statement (revenue, expenses, and profit over a period, on an accrual basis), the balance sheet (assets = liabilities + equity at an instant), and the cash-flow statement (actual money movement, reconciling profit to cash).
Why it matters
Owners who can't read their statements fly on feel: they confuse profit with cash (and get blindsided by profitable-but-broke months), miss balance-sheet rot (swelling receivables, creeping debt), and can't answer the questions lenders, investors, and buyers ask first. Reading them takes an hour to learn and pays forever.
Who should learn it
Every owner — especially anyone who only looks at the bank balance.
What you will understand
- Three statements, one system: period performance, instant position, actual cash movement
- The income statement is accrual — revenue when EARNED, expenses when INCURRED, not when paid
- The balance sheet always balances: assets = liabilities + equity
- Profit is an opinion, cash is a fact — the cash-flow statement reconciles the two
Prerequisites
Common misconception
"Profit means money in the bank." The income statement is accrual: it books revenue when earned (invoice sent, work delivered) and expenses when incurred — not when cash moves. A business can show a profitable quarter while its cash drains (customers paying slowly, inventory piling up, loan principal due) or a loss-making quarter while cash grows (deposits collected upfront). Profit is an accounting opinion; cash is a fact — and the cash-flow statement exists to reconcile them.
