Days payable outstanding shows how many days, on average, a restaurant takes to pay for its purchases and outstanding invoices from the moment it receives the goods or the invoice.
Days payable outstanding (DPO), known in Spain as the periodo medio de pago a proveedores (PMP), is a financial metric that measures the average time a restaurant takes to pay its suppliers. In hospitality it is especially important because cash moves very quickly: guests usually pay in cash or by card and the money arrives within a few days, while suppliers of food, drink, cleaning products, rent, maintenance or software may work with payment terms of 7, 15, 30, 45 or 60 days. That gap creates a cash cycle that can help the business if it is well managed, but it can also hide strain if it is used as improvised financing. A DPO that is too short can leave the restaurant without liquidity even though it is paying impeccably; one that is too long can damage supplier relationships, block deliveries, lose early-payment discounts and create a false sense of available cash.
The figure should be analysed together with cash flow, purchases to sales, OPEX, tax deadlines, payroll and seasonality. Paying late because a formal 45-day term has been negotiated is not the same as piling up overdue invoices through lack of control. Professional DPO management distinguishes healthy current debt, invoices outstanding but within terms, overdue payments, critical suppliers and early-payment discount opportunities. It also helps avoid a common mistake: looking at the bank balance as if it were all free money, when part of that cash belongs to purchases already received and committed.
DPO = (Average supplier balance / Credit purchases for the period) × Days in the period
To calculate days payable outstanding, divide the average balance owed to suppliers by credit purchases for the period and multiply by the number of days analysed. If over a 30-day month the restaurant keeps an average outstanding balance of €18,000 and makes €36,000 of credit purchases, DPO is (18,000 / 36,000) × 30 = 15 days. It can also be measured operationally, invoice by invoice: payment date minus invoice or delivery date. This second view is very useful for spotting specific suppliers that are paid late, even when the overall average looks fine.
A restaurant turns over €85,000 a month and buys €28,000 of food, drink and consumables. Its bank balance looks comfortable mid-month, but on reviewing due dates it finds €22,000 of outstanding supplier invoices, €9,000 of Social Security contributions and €6,000 of rent. Its calculated DPO is 42 days, while most suppliers have agreed terms of 30 days. The problem is not only financial: the fish supplier starts demanding payment up front and the drinks supplier withdraws a volume discount.
Management decides to prioritise payments by how critical each supplier is, formally negotiate 45-day terms with two large suppliers, keep 30 days for critical fresh products and take advantage of a supplier offering a 2% early-payment discount. Within two months DPO falls to 31 days, the commercial relationship improves and the cash forecast no longer depends on guesswork.
Days payable outstanding matters because it connects profitability, liquidity and continuity of operations. A restaurant can sell a lot and still struggle if it does not know when its purchases fall due. It can also appear to have cash available when in reality it is financing itself by delaying payments. Measuring DPO helps you plan treasury, avoid defaults, protect strategic suppliers, negotiate realistic terms, decide when to accept early-payment discounts and spot problems before supplies are cut off.
In multi-site businesses, comparing DPO by site or supplier reveals disorganised buying habits, unrecorded invoices or manual payments that do not follow a common policy. Used well, DPO is not about paying as late as possible, but about paying methodically: within terms, without straining cash and without damaging your purchasing power.
Zindra helps you control days payable outstanding by linking purchases, delivery notes, invoices, due dates, payments, cash flow and financial reporting. You can see which invoices are outstanding, which fall due soon, which suppliers account for most of the debt and how the coming weeks' payments will affect cash. That way the restaurant can prioritise payments, negotiate terms with data and keep a healthy relationship with suppliers without losing sight of its real cash position.

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.
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.
The profit and loss statement (P&L) is the financial report that shows all of a restaurant's income and expenses for a period, revealing whether the business is making an operating profit or a loss.
A restaurant's variable costs are the expenses that change directly or proportionally with the level of sales or production, such as ingredients, drinks, delivery commissions or consumables used per service.
The purchases-to-sales ratio measures what percentage of revenue is being spent on buying ingredients in a period. It is a quick signal for spotting food cost variances, excess stock or planning problems.
Supplier lead time is the time that passes from when a restaurant places a purchase order until it receives the goods and they are ready to use in the kitchen or bar.
Restaurant OPEX is the recurring operating expenditure needed to keep the business running: staff, rent, utilities, purchases, software, maintenance, marketing and outside services.
