Profit is an opinion. Cash is a fact.
Profit is an accounting measure. It depends on when revenue and expenses are recorded, which is often not when the money moves. Sell something today on net-30 terms and you have booked a profit you will not see in cash for a month. Cash is simply what is in the account. You can argue about profit. You cannot argue with a balance.
Where the cash actually goes
Profitable businesses run short because cash leaves through doors the P&L does not fully show:
- Accounts receivable. Money you have earned but customers have not paid yet.
- Inventory. Cash turned into stock sitting on a shelf.
- Loan principal. Repayments reduce cash but are not an expense on the P&L.
- Taxes and owner draws. Real outflows that never appear as operating costs.
- Equipment and capital purchases. Spread over years on paper, paid in full today.
Any one of these can pull your bank balance well below your profit. Several at once, in a growing business, is how a good year turns into a cash scare.
The number to actually watch
The antidote is a simple, forward-looking view of cash: how many weeks or months of runway you have at the current burn, and a rolling forecast of money in versus money out over the next 8 to 13 weeks. It does not need to be elaborate. It needs to exist, and it needs to be looked at before a crunch, not during one. Most owners only build it after their first scare. The ones who sleep well build it before.
Profit tells you whether the business model works. Cash tells you whether you will survive long enough to prove it. You need both on the table, side by side, every month.
