Key takeaways
- Profit and cash are different: a profitable restaurant can still run out of money before a tax payment.
- A 13 week cash forecast, updated every week, is the best early warning tool you can build.
- Know your fixed dates (payroll, rent, VAT or sales tax, loan repayments) and the cash they need.
- Build a reserve in good weeks, and agree your options with the bank before you need them.
In short: profit is an opinion about the month; cash is a fact about the bank. A restaurant can be profitable and still miss payroll, because the money for a tax bill or a stock order leaves before the sales arrive. A simple 13 week cash forecast, kept up to date each week, shows the squeeze weeks ahead.
This is general information, not financial advice; check your own tax and lending position with an accountant.
When restaurants fail, the usual story is not "no profit". It is "no cash on the day a big payment fell due". Understanding the timing of money is therefore as important as controlling cost.
Profit versus cash
A few examples show the difference.
- You buy a new oven for 6,000. It appears in your profit over several years as depreciation, but the cash leaves on one day.
- You order extra stock for a big weekend. The cost is a purchase now and a cost of sales later; cash leaves now.
- A VAT or sales tax payment is due at the end of the quarter. You collected that tax from guests during the quarter, but it was never yours. If you spent it, the bill can be a shock. In the UK, the VAT basics are on GOV.UK.
- You repay a loan. Part of each repayment reduces the loan, not profit.
- The owner draws money for personal use.
None of these show clearly in a profit and loss, and every one of them matters to the bank balance. See gross profit and prime cost for the profit side.
Know your money rhythm
Make a list of what comes in and goes out and when. For a typical restaurant:
Money in
- Card sales: arrive after a delay set by your payment provider.
- Cash sales: banked when you deposit them.
- Online and delivery orders: your own site pays out like card sales; marketplaces pay on their own schedule, often weekly, minus commission.
- Gift cards or pre paid vouchers: cash in now, sales later.
- Other income: events, deposits, catering invoices.
Money out
- Suppliers: often weekly or 30 day terms.
- Payroll: weekly or monthly, plus employer taxes and pension at set dates.
- Rent: monthly or quarterly, usually in advance.
- Tax: VAT or sales tax, payroll tax, corporate tax.
- Loan and finance payments.
- Utilities, insurance, licences, software and repairs.
Some of these dates are fixed and some can be moved. Write down the fixed ones first.
Build a 13 week cash forecast
A 13 week forecast looks one quarter ahead, which is far enough to see a tax payment and near enough to be accurate. Make a table with weeks across the top and these rows:
- Opening bank balance.
- Expected receipts (by channel).
- Payments: suppliers, payroll, rent, utilities, tax, loans, other.
- Closing balance.
Each week, replace the first column with the real result and add a new week at the end. This is called a rolling forecast.
| Week 1 | Week 2 | Week 3 | Week 4 | |
|---|---|---|---|---|
| Opening | 10,000 | 12,500 | 15,000 | 12,500 |
| Receipts | 12,000 | 12,000 | 11,000 | 11,000 |
| Suppliers, payroll, other | 9,500 | 9,500 | 9,500 | 9,500 |
| Rent | 0 | 0 | 4,000 | 0 |
| Tax | 0 | 0 | 0 | 9,000 |
| Closing | 12,500 | 15,000 | 12,500 | 5,000 |
The business is profitable every week, yet by week four it has half the cash it started with. If sales fall by 15% that month, it would be short. The table shows this seven weeks early, which is exactly the point.
Set aside tax money
If you collect VAT or sales tax from guests, treat it as someone else's money. Move it to a separate account each week, or at least calculate it weekly and keep the balance clear. Do the same for payroll taxes. In many countries a late tax payment brings penalties and interest, and the authority may offer a payment plan only if you contact them early. Ask your accountant which schemes exist where you trade.
Use supplier terms carefully
Paying suppliers 30 days after delivery means you sell the stock before you pay for it. That is helpful, but it only works if you pay on the day. Agree terms in writing, keep to them and avoid discount offers that cost more than they save. Know the rules on late payment in your country; in the UK, interest and recovery costs are covered on GOV.UK.
If you are getting short, call the supplier before the due date. Most prefer a conversation to a late payment.
Control stock and waste
Cash sitting on shelves is cash you cannot use. Keep stock levels based on your par levels and expected trade. A big bulk discount rarely pays if half of it spoils. See suppliers and ordering and stock control.
Match the rota to demand
Payroll is the biggest regular cash payment. Check labour hours against sales each week and adjust the next week's rota. See labour cost and the rota.
Plan for slow seasons
Many restaurants have predictable quiet periods: January, mid summer, a religious fasting month, school holidays. Look at the last two years of sales and mark them on your forecast.
In the good months, build the reserve. In the slow months, you can:
- Shorten opening hours.
- Run a simple offer that drives off peak trade (not deep discounts).
- Use the time for training, deep cleaning and maintenance.
- Rely on online collection or delivery to keep volume. See online ordering without commission.
Know your emergency options before you need them
Talk to your bank in a good month about an overdraft or a short term facility. Ask your landlord how they respond to a request for a short rent payment plan. Ask your accountant about instalment arrangements with the tax authority. Do not wait until you are overdue.
Weekly cash habits
- Update the forecast every Monday.
- Check the bank and the till takings against your sales report.
- List payments due in the next three weeks.
- Review stock levels against sales.
- Decide any action now, not after payroll.
DineHarbor's reports help with the sales side of the forecast by showing recent sales and order counts, and the weekly numbers guide lists what to check.
Common mistakes
- Spending the tax money.
- Buying equipment from cash that was needed for payroll.
- Forgetting that rent is due in advance.
- Treating a good weekend as a trend.
- Having no reserve. See start up costs.
Warning signs of a squeeze
Several signs show up before an actual shortfall. You begin paying suppliers a few days late. The bank balance dips just before payroll every month. You find yourself delaying repairs. The tax payment is covered only if next week is busy. Stock is cut below sensible levels to save cash, and then dishes run out. If you see two of these at once, update the 13 week forecast the same day and plan an action.
Daily money habits
Reconcile the till to the day's takings every night, and bank cash on a regular schedule. Keep a clear record of card payouts against sales, so that a missing payment is noticed within days, not at the month end. If you use several channels, such as the dining room, collection, delivery and a marketplace, list them separately, because each pays on a different timetable. Check each payout against what you expect and chase any difference quickly.
Separate personal and business money. Set a regular owner drawing that the forecast can carry, and avoid taking more in strong weeks unless the reserve is full.

Questions and answers
Why is my restaurant profitable but short of cash?
Profit counts the sale and the cost in the month they happen; cash counts when money moves. Tax payments, stock purchases, equipment, loan repayments and owner drawings take cash without reducing profit in the same way.
How much cash reserve should a restaurant keep?
A common target is two to three months of fixed costs and payroll, more if trade is seasonal. Set yours from your own break even and the length of your slowest season.
How long do card payments take to arrive?
It depends on your payment provider and plan. Many pay out within one to a few working days, but check your agreement and plan your cash around the real delay.
Can I negotiate payment terms with suppliers?
Often yes, once you have a track record. Longer terms help cash flow, but late payment damages the relationship and may carry interest. In the UK, late payment rules are on GOV.UK.
What should I do if I see a shortfall coming?
Act early: talk to your bank, your landlord and key suppliers before the date, cut or delay non essential spending, and check whether tax payment plans are available from the tax authority.
