How to Run a Pub Profitably in 2026

Last updated: 26 June 2026

Most pubs fail not because they don’t work hard enough, but because they measure the wrong numbers. You can be pulling pints twelve hours a day and still haemorrhage money without realising it — because nobody’s actually looking at what’s walking out the back door versus what’s ringing on the till. That’s the gap where profit dies. If you’re running a pub right now and your stock variance sits somewhere between “I haven’t got a clue” and “the spreadsheet says we’re okay”, you’re losing serious cash every single week. The good news: once you fix this, you’ll claw back between 1–2 gross profit (GP) points within a couple of months. This guide shows you exactly how to run a pub profitably by measuring what actually matters: wet GP by line, real stock counts, and reconciliation that you can trust. You’ll understand why your brewery stocktaker isn’t enough, what a weekly line check really does, and how to build a routine that takes 45 minutes instead of hours.

Why Most Pubs Fail to Measure Profit Correctly

You walk into a pub at closing time and ask the landlord how much they made today. Nine times out of ten, they’ll tell you the till takings. Wrong number. Takings tell you what customers paid you. They don’t tell you whether you actually made any money.

The most effective way to measure pub profitability is to track gross profit by product line—spirits, draught beer, cask, soft drinks—not a single headline stock figure. The reason most pubs can’t see their profit is because they are looking at the wrong metric. Your EPOS tells you what sold. It doesn’t tell you whether the stuff you sold cost you more than you thought it did, or whether you poured more of it than you charged for.

Here’s what I see most often: a licensee reconciles stock once a month, usually under pressure from the brewery or the pubco. The variance is 2–3%, they shrug, maybe they tighten up the team for a week, then it slides back. Nobody asks the simple question: which line is bleeding? Is it the Guinness? The vodka? The lager? If you don’t know, you can’t fix it. And if you can’t fix it, you’re throwing away the margin that actually pays your rent.

The real issue is that most pub stock losses aren’t theft. They’re:

• Over-pouring: A free-poured 25ml spirit measure is often 32–35ml. That’s a 30% giveaway per pour.
• Cellar temperature: Ale that sits at 14°C instead of 13°C loses condition, goes flat, gets binned.
• Line cleaning waste: Running lines on a Monday morning without measuring what comes out. That’s 2–3 pints of product per line, every week, vanishing into gutters.
• Forgotten spillage and breakage: Dropped crate, split keg, broken bottle—nobody logs it because it’s embarassing.
• Partial kegs not tracked: You tapped a keg of lager on Thursday, it’s now Friday. How many pints are left? Most licensees guess.

When you add these up across a week, it’s not 0.5% variance. It’s real money. And nobody’s counting it because there’s no system.

Understand Gross Profit by Line, Not a Single Stock Figure

Here’s the insight that changes everything: Your profit doesn’t live in an average stock variance figure—it lives in what you earned on spirits versus what you earned on draught, and whether one line is subsidising another.

Let’s say your headline stock variance is 0.8%. That sounds okay. But what if your spirits are at 0.3% variance (tight, controlled, profitable) and your draught is at 1.8% (haemorrhaging)? The 0.8% average hides the real problem. You’re making good money on vodka because you’re using a measure and logging everything. You’re losing it on Guinness because your lines are hot, your cellar temperature has drifted, and nobody’s measuring what comes out when you run the lines.

This is why SmartPubTools was built around cellar tracking, not just a general stock app. Most point-of-sale systems will tell you what you sold. They won’t tell you whether the thing you sold cost you more than it should have.

To run a pub profitably, you need to understand:

• Wet GP by line: How much profit did spirits make you this week? How much did draught? How much did cask ale?
• Cost of goods sold (COGS): What percentage of your takings disappeared into stock? Should be 28–32% for a well-run pub. Anything above 35% is a warning sign.
• Which lines are pulling their weight: If your premium lager is sitting at 1.5% variance and your house beer is at 0.4%, one is under-priced and the other is overpriced, or one is being poured differently than the other.

Once you know these numbers by line, you can start making decisions. Tighten the draught lines. Retrain the staff who free-pour spirits. Check the cellar temperature. Measure what you’re throwing away. The moment you start measuring by line instead of guessing at an average, profit moves.

Implement Weekly Stock Counting as Your Profit Foundation

Weekly stock counting combined with same-day till reconciliation is the single most effective practice to identify and stop profit leaks in a pub. I know what you’re thinking: I don’t have time to stocktake every week. My spreadsheet works fine. My brewery stocktaker will catch anything serious. None of that is true, and I’ll explain why in a moment. But first, the reality of why weekly counts work.

When I was running stock on a tangle of spreadsheets and still losing track of partial kegs and spirit measures, I built a simple count routine around a dipstick and a set of scales. The weekly variance went from guesswork to a number I could trust within a fortnight. That wasn’t magic. That was just disciplined, consistent measurement.

Here’s what a weekly count looks like in practice:

• Monday or Tuesday morning (45 minutes, one person): Walk the cellar with a dipstick, measure every cask and partial keg. Write down the depth. Weigh every open spirit bottle. Count sealed stock. Log it.
• Same day, before closing: Pull the till report. Compare what you counted against what the till says sold. Reconcile the difference. If it’s more than 0.5% variance, you know something shifted that day.
• Same week: If a line is drifting, you catch it before it becomes a £500 problem. You retrain a bartender, check a line temperature, or measure what’s being wasted.

The reason this works is because variances are small and fresh. You remember what happened on Monday. You know which member of staff was on. You can trace the problem. If you wait a month, the variance is so big you can’t see the source anymore. You just shrug and move on.

Regarding the common objections:

“My spreadsheet works fine.” No, it doesn’t. It works until it doesn’t, which is usually the moment you need it most. Excel is great for accounting. It is terrible for real-time cellar tracking because you’re moving data manually between systems, you’re updating it by hand, and one typo ruins the whole reconciliation. By the time you notice the error, you’ve already lost a week’s worth of margin.

“My brewery stocktaker will catch anything serious.” The brewery stocktaker comes once a month (if you’re lucky) and they’re measuring your liability to the brewery, not your profit. If you have a 2% variance, they note it and move on. They’re not asking which line it is, why it happened, or whether it’s a measurement issue or an actual loss. You’re supposed to know that. And you can only know that by counting yourself, weekly, and finding the pattern.

“I don’t have time to stocktake every week.” You have time to lose £3,000–£5,000 a year? Because that’s what a 1% stock loss on wet sales costs a typical pub. A weekly count takes 45 minutes. You’re not choosing between stocktaking and running the bar. You’re choosing between 45 minutes of counting and £3,000–£5,000 of margin. The math is not complicated.

If you’re serious about profitability, weekly counts are non-negotiable. The StockTap pub stock app is built specifically to make this routine fast and reliable enough that you’ll actually do it week after week, not just when you panic about variance.

Fix Your Cellar and Draught Lines Before They Kill Your Margin

Draught beer is usually where pubs haemorrhage the most stock without realising it. Cask ale, lager, stout—the margin on draught is typically 50–60%, which is why it’s so profitable. It’s also why it’s so dangerous when it goes wrong.

Three things kill draught margin silently:

1. Cellar temperature. Cask ale should sit at 13°C. If your cellar runs at 14°C or higher, the beer loses condition faster, goes flat, and you have to bin it. That’s product cost for nothing. Temperature should be logged daily. If you’re not logging it, you don’t know whether your variance is waste or measurement error.

2. Line cleaning waste. Running the lines on Monday morning is essential. But how much comes out? Most pubs don’t measure it. You’re running 6 lines, each one is 30 feet long, you’re dumping 2–3 pints per line, and nobody’s logging it. That’s 12–18 pints of Guinness, lager, and cask heading to the drain, every week, unpaid for. If you measure this consistently, you can account for it in your variance. If you don’t, it becomes a mystery variance that nobody can explain.

3. Line temperature. Draught lines should run at 5–7°C. If the line temperature creeps above 10°C, the beer starts to spoil inside the line. Punters can taste it. You get complaints. And half the time you bin the line to get it back to spec, losing another 2–3 pints.

Fix these three things and your draught variance will tighten by 0.5–1.0% within a month. That’s £1,500–£3,000 on a typical pub. It’s not a theory. It’s physics and discipline.

For spirits, the issue is different. It’s over-pouring. A bartender who free-pours will pour 32–35ml when the measure is 25ml. That’s a 30% giveaway per pour, and it compounds across a week into serious money. Solution: use a measure, every time. Some licensees think this slows down service or upsets customers. It doesn’t. It takes an extra two seconds and most punters respect precision. The ones who complain are usually the ones ordering doubles anyway.

Reconcile Stock Against Till Data the Same Day

This is the piece most pubs get wrong. They count stock, they check the till, but they don’t reconcile the same day, and they don’t look for the actual variance by line.

Here’s what proper reconciliation looks like:

• Count stock on Monday morning (spirits by weight, draught by dipstick, sealed stock by unit).
• Before closing Monday, pull the till report showing what sold that day.
• Compare: If the till says you sold 12 Guinness and your cellar count shows the cask dropped by 13 pints, you have a 1-pint variance on Guinness for that day. You can probably explain it (spillage, sample for a customer, line cleaning waste that wasn’t logged). If you can’t explain it, you investigate.
• If you wait until Friday to reconcile, the variance is now 5 days old. You’ve sold 60 pints of Guinness since Monday. That 1-pint variance is buried in a much bigger number and becomes invisible.

Same-day reconciliation is how you move from guessing about variance to understanding it. It’s also how you catch systematic problems early. If draught variance starts drifting upward on Thursdays and Fridays, you know it’s a cellar temperature issue (the weekend is warm) or a staff issue (specific bartenders are working those shifts). You can’t see that pattern if you reconcile monthly.

The reconciliation itself is simple: Stock count (opening + deliveries – closing) should equal till sales (quantity sold × price) minus waste logged (spillage, breakage, line cleaning, samples). If it doesn’t, the variance is either measurement error, unlogged waste, or actual loss. You investigate from there.

Automate Your Numbers or You Will Lose the Plot

I’ve met dozens of licensees who swear by their spreadsheet. I’ve also met dozens more who gave up on their spreadsheet because it took too long, they made mistakes, and they stopped using it. That’s usually when the profit problems start.

A spreadsheet works if you’re disciplined. But pub licensees are busy. You’re staffing, you’re pouring, you’re dealing with suppliers, you’re managing break-ins and complaints. The moment you miss one week of updates, the spreadsheet becomes unreliable. The moment you manually move data from one system to another, you introduce typos. The moment you introduce typos, you lose faith in the numbers. The moment you lose faith, you stop looking at them.

A proper pub management system—one built by someone who actually runs a pub—removes the friction. You count stock once a week in 45 minutes. The app logs it. It automatically reconciles against till data. It shows you GP by line. It flags variances. It gives you a weekly P&L. You don’t need to move data around. You don’t need to build formulas. You just need to count, and the system does the rest.

That’s the difference between theory and practice. In theory, you can run a pub on spreadsheets and discipline. In practice, you need a system that makes it easy, because busy licensees will use an easy system and ignore a complicated one.
