Key ideas in How Business Keeps Score
- A business's total belongings are divided entirely between outside lenders and inside owners
- There is no third group claiming company assets; every asset is financed by either debt or equity
- Creditors get paid first, and owners claim whatever is left
- Assets must be controlled or owned directly by the business, not borrowed from employees
- An asset must provide measurable future economic benefit or cash flow
- Vague hopes or future intentions cannot be recorded as assets until concrete value exists
- Liabilities are not just bank debt; they include any future obligation owed to an outside party
- Receiving cash in advance creates a liability to deliver future goods or services
- Getting supplies on credit creates an obligation to pay later
- Owner's equity is whatever is left over after settling all obligations to outsiders
- The accounting formula can be rewritten as Assets minus Liabilities equals Equity
- Equity shrinks whenever debts grow without an equal increase in assets
- Every incoming asset must come from somewhere: paid with another asset, borrowed, or funded by the owner
- The equation must balance after every single transaction because resources cannot appear out of nowhere
- Gaining an asset always causes an equal decrease in another asset, an increase in liabilities, or an increase in equity
- Every single transaction must touch at least two accounts
