Guide · Cash flow · UK
Peak months and lean months arrive every year. Planning cash flow around them is how strong weeks fund the quiet ones instead of being spent twice.
Hospitality revenue rarely arrives in a straight line. Christmas parties, a warm bank holiday weekend and the summer tourist run can make one month worth two of another, while the fixed costs underneath, rent, core wages, utilities and finance, barely move. Cash flow planning is the discipline of anticipating those swings before they arrive, so the good months fund the lean ones instead of being spent as if every month will look the same.
A business can be profitable across a full year and still run out of money in February, because profit and cash are not the same thing. Restaurants typically work on net margins in the single digits and can see revenue swing by half or more between their busiest and quietest periods, yet suppliers still need paying, payroll still runs and the quarterly rent still lands. Cash-flow problems, not thin margins alone, are among the most common reasons otherwise viable kitchens close. The operators who stay open are usually the ones who saw the compression point coming and planned the reserve to cross it, rather than discovering it when a card payment bounces.
Seeing it coming
The single most useful tool most operators do not keep is a rolling thirteen-week cash-flow forecast, updated every week with what actually traded. A snapshot of today's bank balance says nothing about whether next month's payroll is covered or whether the quiet weeks after the festive peak will leave enough behind to buy stock. A forecast that looks a quarter ahead answers those questions while there is still time to act, which is the whole point: it converts a nasty surprise into a decision made calmly, weeks in advance.
Build it from your own history. Last year's monthly pattern, adjusted for what has changed, tells you which weeks will be strong and which will be thin, and lets you map the big outgoings, rent, VAT, tax and any loan repayments, against the weeks that can least afford them. Managing cash by watching the bank balance rather than forecasting future need is one of the most expensive habits in the sector, precisely because it hides the shortfall until it has already happened.
The forecast is only half the job; the other half is building the reserve while the money is there. A peak month is the moment to set cash aside deliberately, not to spend the whole uplift as if it were normal trading, because the reserve you build in December is what pays the rent in February.
Timing the outgoings
Once you can see the year, you can shape it. Capital spend, deep refurbishments and large stock commitments belong in or just after the strong months, not on the eve of a known trough. Supplier terms, deposit-led event work and delivery settlement all affect when cash actually arrives versus when the sale is booked, and a mismatch there can squeeze working capital even in a busy week. Watching the gap between gross profit and cash is central here; a kitchen where gross profit is fine but cash is tight usually has a timing problem, not a pricing one, and timing is something a forecast lets you fix.
Protecting the plan
A cash-flow plan is only as good as the surprises it does not absorb, so the costs you can schedule should be scheduled rather than left to ambush you. Planned maintenance, deep cleaning and statutory checks are known quantities that belong in the forecast as fixed lines, which is far cheaper than an emergency call-out landing in your worst week. Folding them into a maintenance budget that prevents surprises keeps the unpredictable spend small enough for the reserve to cover, so a seasonal trough stays a quiet month rather than becoming a crisis. This is general guidance rather than financial advice, but the principle holds across almost every hospitality model: plan the peaks, fund the troughs, and let the fixed costs stay fixed.
Questions
Profit is measured across a full year, but cash is spent week by week. A kitchen can be profitable annually yet hit a shortfall in a quiet month, because fixed costs like rent, wages and utilities continue while revenue drops. Forecasting cash separately from profit is what catches this in time.
It is a rolling projection of money in and money out for the next quarter, updated every week with actual trading figures. It shows whether upcoming payroll, rent and stock purchases are covered, giving an operator time to act before a shortfall arrives rather than after.
There is no single figure, but the reserve should be large enough to carry fixed costs through the known trough between your peak periods. Building it deliberately during strong months, rather than spending the whole uplift, is what makes the quiet months survivable.
Time large capital spend and major stock commitments for during or just after your strong trading periods, never immediately before a known quiet spell. Lining big outgoings up against strong weeks is one of the simplest ways to protect working capital.
Yes. Planned deep cleaning, extraction maintenance and statutory checks are predictable costs that should sit in the forecast as fixed lines. Scheduling them keeps them cheap and avoids an emergency call-out landing in your weakest trading week.
