Cash flow in a restaurant is the movement of money in and out of the business. Managing cash well is vital for the restaurant's survival, even if it is profitable on paper.
Cash flow is the financial indicator that measures the real money coming into and going out of a restaurant over a given period. Unlike accounting profit, which can include income and expenses that have been accrued but not yet received or paid, cash flow reflects the real money available in the till and the bank. In hospitality, this distinction is critical: a restaurant can be profitable in its income statement but go under for lack of liquidity if payments to suppliers fall due before sales are collected. The hospitality cash cycle has one favourable quirk: customers pay on the spot (in cash or by card, which settles in 24-48 hours), while suppliers usually give 30-60 days' credit.
This creates a positive float that funds the operation, but it also sets a trap: if sales drop sharply, payments owed to suppliers keep falling due based on earlier purchases, putting cash under strain. The main components of a restaurant's cash flow are: sales receipts (cash, cards, delivery apps), payments to food and drink suppliers, payroll and Social Security (the biggest fixed monthly payment), rent, utilities (electricity, gas, water, telecoms), loan repayments, quarterly taxes (VAT, IRPF income tax withholdings, corporate income tax) and one-off expenses. Managing cash flow professionally means preparing a rolling 12-week cash forecast, identifying payment peaks (mid-month and month-end for payroll, the 20th for Social Security, quarter-ends for tax) and keeping a liquidity cushion equivalent to 1-2 months of fixed costs as an emergency reserve.
Cash flow = Receipts in the period - Payments in the period
Operating cash flow is calculated by subtracting all payments made in a period from all receipts collected in the same period. If in a month you collect €45,000 (€40,000 by card and €5,000 in cash) and pay out €38,000 (€15,000 payroll, €12,000 suppliers, €4,500 rent, €2,000 utilities, €4,500 other), your monthly cash flow is +€7,000. For the cash forecast, you project expected receipts (based on sales history and seasonality) and committed payments (known due dates) week by week, identifying the points where the balance could fall below your safety minimum. Cumulative cash flow shows your cash position at the end of each period.
Your restaurant turns over €50,000 a month on average, with a net profit of 8% (€4,000). That looks healthy, but then January comes: sales fall by 30% in the post-Christmas slump (the cuesta de enero), to €35,000, but payments stay the same: €15,000 of payroll, €10,000 to suppliers (for December's orders), €4,500 of rent, €8,000 of VAT for the fourth quarter (built up from October to December) and €2,500 of utilities. Total payments: €40,000. With receipts of €35,000, your cash flow is negative: -€5,000.
If you had no cash reserve, you cannot pay wages on time. This explains why so many profitable restaurants close after the first weeks of January. The solution: always keep a cushion of at least €10,000-15,000 to absorb these seasonal dips.
Cash flow is the lifeblood of the business; without it, the restaurant dies even if it is profitable. Industry statistics suggest that 60% of restaurant closures in Spain are caused not by a lack of profitability but by liquidity problems. Hospitality is highly seasonal (dips in January, September and after holidays) and has concentrated payment peaks (quarterly taxes, the extra salary payments, pagas extra, that are standard in Spain). Without a cash forecast, these dips catch managers off guard.
Managing cash flow also has a direct impact on your relationship with suppliers: a restaurant that pays on time negotiates better prices and terms; one that pays late loses good suppliers and ends up paying more. Managing cash professionally also helps you spot opportunities: if you have surplus cash, you can negotiate early-payment discounts (typically 2-3%) that improve your margin directly.
Zindra brings together your sales, purchases and expenses to generate 12-week cash forecasts automatically, alerting you when a payment peak could cause strain and helping you plan ahead, for example by renegotiating payment terms or adjusting orders.

Food cost is the percentage of a dish's selling price that goes on the cost of its ingredients. It is the single most important indicator of how profitable your menu is.
The staffing ratio is the relationship between the number of employees and the restaurant's customers, tables or revenue. It tells you whether you have the right team to give good service without costs running away.
Prime cost (coste primo in Spanish) is food cost plus staff cost. It is the most complete measure of a restaurant's direct operating cost and should stay between 55% and 65% of turnover.
