A business can be profitable on paper and fail because it cannot pay what it owes when it is due.
Profit and cash are different
Profit recognises revenue when earned; cash arrives when paid.
Which produces a gap that must be funded.
Growing businesses experience this most severely.
The working capital cycle
Time from paying for inputs to receiving payment from customers.
Which must be funded from somewhere.
A longer cycle requires more cash for the same revenue.
Why growth consumes cash
More sales require more stock, more staff and more receivables before payment arrives.
Which means rapid growth increases cash requirements faster than it increases cash.
Businesses have failed while growing quickly and profitably.
Receivables
Money owed by customers.
Which is an asset that does not pay wages.
Days sales outstanding is the measure and is worth tracking closely.
Late payment
Customers paying beyond agreed terms.
Which has been subject to legislation in several jurisdictions.
Statutory interest on late commercial payment exists and is rarely claimed.
Inventory
Stock is cash converted into goods.
Which becomes cash again only when sold and paid for.
Slow-moving stock ties up cash indefinitely.
Forecasting
A rolling projection of cash in and out by week.
Which is the single most useful financial document a small business maintains.
It identifies problems in time to act rather than after the fact.
Sources of funding
Invoice finance, overdrafts and term borrowing.
Which each have costs and are far easier to arrange before they are urgent.
Lenders respond very differently to a planned request than to a crisis.
The practical discipline
Invoice promptly, chase early, negotiate terms deliberately, and forecast weekly.
Seasonality
Businesses with concentrated trading periods carry costs year round.
Which requires funding the quiet months from the busy ones.
Forecasting by week rather than by year is what makes this visible.
Payment terms
What you offer customers and what suppliers offer you.
Which together determine the funding gap.
Negotiating either direction improves cash position without changing revenue.
Deposits and staged payments
Collecting money before or during delivery.
Which transforms working capital requirements.
Many businesses could ask and do not.
Credit control
Systematic chasing before invoices become overdue.
Which is more effective than pursuing after the fact.
A polite call before the due date changes payment behaviour measurably.
The single most useful document
A thirteen-week rolling cash forecast, updated weekly.
Tax obligations
Amounts collected on behalf of authorities are not the business's money.
Which is a common and serious error.
Using withheld tax for working capital creates personal liability in many jurisdictions.
Supplier relationships
Communicating early about payment difficulty.
Which generally produces better outcomes than silence.
Suppliers who are informed frequently accommodate; suppliers who are ignored do not.
Separate accounts
Holding tax and payroll amounts separately.
Which prevents spending money that is already committed.
This is a simple discipline that prevents a serious category of failure.
Getting help
Accountants, business advisers and lender relationship managers all respond better to early contact.
The summary
Profit is an opinion and cash is a fact, which is why the forecast matters more than the accounts.
Profit against cash
A profitable business can be unable to pay its bills.
Which is the central and frequently learned-too-late point.
Growth increases the gap because it consumes cash before generating it.
The working capital cycle
Time between paying suppliers and being paid by customers.
Which must be funded from somewhere.
Shortening it is frequently more valuable than increasing sales.
Receivables
Invoicing promptly, chasing systematically and setting terms deliberately.
Which is unglamorous and directly determines cash position.
Most small businesses invoice later than they could.
The rolling forecast
Expected cash in and out over the coming weeks.
Which is the single most useful document a small business maintains.
It should be updated weekly rather than monthly.
Payables
Negotiated terms with suppliers.
Which extend the cycle and depend on relationships.
Paying late without agreement damages both supply and reputation.
Seasonality
Predictable variation across the year.
Which requires building reserves in strong periods.
Businesses that treat peak months as normal run into difficulty in the trough.
Growth funding
Rapid growth consuming more cash than it generates.
Which is why profitable growing businesses fail.
Financing options include invoice finance, overdrafts and slowing growth deliberately.
Early warning signs
Stretching supplier payments, delaying tax and using overdrafts continuously.
Which indicate a structural problem rather than a timing one.
Acting at that point produces far more options than waiting.
Where to start
Build a thirteen-week cash forecast and update it every week.
Which is the standard tool and is simple enough for a spreadsheet.
Businesses that maintain one rarely get surprised.
A closing caution
None of this is prescriptive. Businesses differ by sector, by scale and by stage, and practices that work well in one context fail in another for reasons that are not always visible from outside.
What is consistent is that the businesses handling these questions well tend to have written something down, measured it in a defined way, and reviewed it on a schedule rather than when a problem forces the issue.
Where a decision carries legal, tax or employment consequences, professional advice specific to your jurisdiction is worth the cost, and this article is general description rather than advice.
