What's the difference between revenue, profit, and cash in the bank, and why did my accountant say I'm profitable when my account is nearly empty?
The short answer
Profit is an accounting statement (revenue minus expenses on paper), while cash is what's actually in your account right now, and they diverge whenever customers pay late, you prepay expenses, or you hold inventory.
