Accounts payable

Money you owe suppliers for things already received.

Example

An unpaid $9,000 cloud bill from last quarter.

Stretching payables buys short-term runway and burns supplier goodwill. It is a lever, not a strategy.

Accounts receivable — Money customers owe you for work already delivered.
Cash flow — The actual movement of money in and out of your bank account, as distinct from revenue you have earned but not been paid.
Balance sheet — A snapshot at one moment of what you own (assets), what you owe (liabilities), and the difference (equity).

Profit is not cash — Profitable companies go bankrupt. This is the single most important idea in company finance and almost nobody explains it to founders. (12 min)
Reading a balance sheet — What you own, what you owe, and what is left. A snapshot rather than a period — and the one that has to balance. (10 min)
Working capital and why growth eats cash — The money trapped between doing the work and being paid for it. It is why profitable, growing companies run out of money — and it is the cheapest financing you are not using. (12 min)
