profit is an accounting opinion, cash is a fact; timing of revenue and expenses tells the survival story
Cash beats profit because profit records economic activity when it occurs, not when money changes hands. A business can show a healthy profit and still go bankrupt if its sales have not yet been collected into cash.
Accrual accounting separates revenue recognition from cash collection, and expense recognition from cash payment. When you sell on credit, you record the sale immediately and the receivable appears on your balance sheet. When you buy on credit, you record the expense even though payment may be weeks away. These timing differences live in working capital: accounts receivable, accounts payable, inventory, prepaid expenses, and deferred revenue. Depreciation and other non-cash charges also make profit lower than cash, but working capital changes are often the much larger gap.
Imagine a contractor completes a $100,000 renovation in March. The client is billed in March and pays in June. The contractor pays $65,000 for labor and materials in March. In March, the income statement shows revenue of $100,000, expenses of $65,000, and profit of $35,000. The bank statement tells a different story: $65,000 went out, and nothing came in. If the contractor has no other reserves, payroll and suppliers cannot be paid. The business is profitable and insolvent at the same time.
Many people believe cash flow equals profit plus depreciation. Depreciation is only one source of difference. A rapidly growing business commonly sees profits rise while cash falls, because every new sale adds an unpaid receivable or more inventory sitting in the warehouse. Meanwhile, a shrinking business can collect its old receivables and cut cash expenses, producing cash while profits fall. Profit is also shaped by assumptions: depreciation method, inventory costing, estimates for bad debts and warranty claims. Change those assumptions and profit changes, but cash does not. That is why cash is a fact and profit is an opinion.
For a simple cash-only business where customers pay immediately and bills are paid on the spot, profit and cash move almost in lockstep. For a mature company with stable working capital, annual profit is a reasonable approximation of cash generation from operations. And over the entire life of a business, total profit and total cash generation will be close after accounting for owner investments and distributions. But for any business that must pay bills before collecting from customers, cash is the constraint that decides whether the company exists next month. Profit tells you whether the business model works; cash tells you whether you get to survive long enough to find out.
Cram A business that shows a profit is doing fine, right?
Rep Profit says you sold well. It says nothing about the money in the bank.
Cram Wait, profit is money. They are the same thing.
Rep Cash is a fact. Profit is an accounting opinion. You can have one without the other.
Cram How? If I sold a hundred, I have a hundred.
Rep Not if the customer has not paid yet. You book the sale, you count the profit, and the cash arrives later.
Cram So when do you actually count the sale?
Rep When you earn it, not when you get paid. That is accrual accounting.
Cram And you count expenses the same way.
Rep Exactly. You record a cost when you owe it, even before cash leaves. Timing shifts everything.
Cram So a profitable company can still go bust?
Rep It can. Lots of profitable companies die because they run out of cash paying last month's bills.
Cram So profit tells you that it worked, and cash tells you it will survive.
Rep Now you have the model.
