Cash Flow Is Not Profit, and the Difference Ends Businesses

One of the more counterintuitive facts about running a business is that profitability offers no protection against running out of money. Businesses with healthy margins and growing revenue fail with some regularity, and the cause is rarely the absence of profit. It is the gap between when work is done and when the money for it actually lands.

Two different questions

Profit answers the question: over this period, did what we earned exceed what it cost? Cash answers a blunter one: is there money in the account today to meet what is due today? Accounting deliberately allows these to differ, because recognising revenue when work is performed gives a truer picture of activity. It also means a profitable month can coincide with an empty account.

Profit is an opinion about when something counted. Cash is a fact about whether it arrived.

Where the gap comes from

• —Work delivered now, invoiced later, paid later still.
• —Inventory or materials bought upfront and sold over following months.
• —Wages and rent that fall due on a fixed schedule regardless of collections.
• —Tax on profits earned in a period, payable after the cash has been spent.
• —Growth itself, which consumes working capital before it repays any.

What actually closes the gap

The levers are unglamorous and largely within an owner’s control. Ask for deposits on work that requires upfront outlay. Invoice the day the work is complete rather than at month end. Set payment terms deliberately and follow up on them without apology. Match the term of any borrowing to the life of what it funds. Hold a reserve sized to the real gap rather than to a comfortable assumption about it.

Collection in particular is frequently treated as an administrative afterthought when it is closer to core operations. A business that delivers well and collects slowly is lending money to its customers, usually at no interest, often without having decided to.

The number worth knowing weekly

One figure does most of the work: how many weeks the business could continue meeting obligations using money it actually has and payments it can reasonably expect. Calculated on real numbers rather than forecasts, and revisited weekly, it converts an anxiety into a variable — and variables can be managed.
