Why Profitable Restaurants Still Run Out of Money

A restaurant can be profitable on paper and still fail to pay its suppliers. It happens regularly, and the owners rarely see it coming, because they were watching the wrong number.

Profit is an accounting measure over a period. Cash is what's in the account on the day the payment is due. They diverge more than people expect, and the gap is where businesses die.

Where profit and cash come apart

Timing

You pay for stock before you sell it. Wages go out weekly or fortnightly regardless of trade. Rent is due on a fixed date. Meanwhile a quiet fortnight has already happened and the money that should have covered those obligations never arrived.

Costs that never touch the P&L

Loan principal repayments are cash out but not an expense — only the interest portion appears. Same with equipment bought outright, and with the tax bill sitting against last year's profit. A business can show a healthy net margin while the bank account drains toward obligations the P&L never mentions.

Depreciation, in reverse

Depreciation reduces profit without touching cash, so a restaurant can look barely profitable while generating decent cash. This is the one that cuts in your favour — and it's why judging health by profit alone misleads in both directions.

The 13-week forecast

The single most useful financial tool in a restaurant, and it lives in a spreadsheet.

Thirteen columns, one per week. Down the left, every cash movement — not accounting categories, actual payments.

• In: forecast takings by week, based on last year adjusted for what you know
• Out: supplier payments by due date, wages, PAYE and GST, rent, insurance, loan repayments, subscriptions, anything scheduled
• Closing balance carried into the following week

Update it every Monday with actuals and roll it forward one week. It takes twenty minutes once built.

What it gives you is time. A shortfall in week nine is a problem with eight weeks of options — trim a roster, delay a purchase, talk to a supplier, arrange facility headroom. The same shortfall discovered on the day is a crisis with none.

How much should you hold in reserve?

Eight weeks of operating expenses is the minimum. Twelve is comfortable.

Operating expenses meaning everything you'd have to pay if revenue fell substantially — rent, salaried wages, insurance, loan repayments, utilities. Not food cost, which falls with trade.

Most restaurants hold nothing like this, which is why an equipment failure or a bad month escalates so fast. The reserve isn't idle money; it's what converts an emergency into an inconvenience.

Build it the way you'd build any savings — a fixed weekly transfer to a separate account, treated as non-negotiable. Waiting for a surplus large enough to move in one go means it never happens.

Seasonality is the usual killer

Almost every restaurant has a strong season and a weak one. The failure pattern is consistent: spend at the rate the strong months generate, then meet the quiet period with nothing set aside.

Work out the shortfall in advance. Take your quiet-season weekly revenue, subtract weekly costs, multiply by the number of weeks. That's what the strong season has to fund on top of its own costs — and it's a number you can plan against rather than discover.

It's one of the six patterns behind most restaurant failures, and among the most preventable.

Practical levers when cash is tight

• Talk to suppliers early. A supplier told in advance will usually work with you. One told after a missed payment moves you to cash-on-delivery, which makes everything worse.
• Reduce stock holding. Every dollar of inventory is cash sitting on a shelf. Most kitchens carry more than they need, particularly in dry goods.
• Arrange facilities before you need them. Overdrafts are far easier to obtain when the accounts look healthy. Get the facility in place and leave it unused.
• Take deposits on functions. Large bookings should contribute cash before they consume stock and labour.
• Separate the tax money. GST and PAYE are not yours. Move them to a separate account as they accrue and the quarterly bill stops being an event.
