Bar Stock Control in UK Pubs 2026

Last updated: 11 April 2026

Most pub landlords spend more time chasing bad stock counts than actually running their business. You’ll do a Friday night count, find a £300 discrepancy, spend two hours working backwards through till rolls, and never quite figure out where it went. Then you do it again next week.

Stock control isn’t the sexy part of pub management — nobody gets excited about reconciling draught beer against till sales — but it’s the difference between a pub that makes money and one that bleeds it. When I took over Teal Farm Pub in Washington, Tyne & Wear, bar stock control was exactly the chaos I just described. Saturday nights would run hot, staff would pour from muscle memory without ringing it in, and by Tuesday the figures made no sense.

In this guide, you’ll learn the exact system that turned that around: the real-world methods that work in a busy wet-led pub handling simultaneous transactions, staff mistakes, and the unpredictable ebb and flow of a Saturday night. Not theory. Not what consultants tell you works. What actually works when you’re managing 17 staff across FOH and kitchen and you need to know tonight whether you’ve got a theft problem or a training problem.

Why Most Pubs Fail at Stock Control

The most common reason pub stock control fails is that it’s treated as a one-person job instead of a system that depends on every member of staff. The landlord or manager does the count on a Tuesday morning, finds the numbers don’t match till sales, assumes there’s theft, and moves on. Nothing changes. The next week it happens again.

I’ve watched this pattern repeat in dozens of pubs. The real problem isn’t dishonesty — most of the time it’s not. It’s that nobody involved understands the relationship between what they pour, what they ring in, and what the numbers say on paper. A member of bar staff pours a pint, gets interrupted mid-transaction, finishes the pour but doesn’t ring it in. They’re not trying to steal. They genuinely forgot, and by the end of their shift they’ve forgotten it ever happened. Multiply that by six staff members over five nights and you’ve got a £200 variance by Friday.

The second reason stock control fails is that it’s invisible. You can see when a customer complains about a pint, but you can’t see the £40 worth of draught Guinness that went down the drain because nobody cleaned the line properly. You can’t see the spirits poured but not rung in because it was busy and someone’s finger slipped. These aren’t big incidents — they’re small leaks that happen dozens of times a week.

The third reason is that most traditional stock control systems are designed for restaurants or retail, not for pubs with draught product. A restaurant counts ingredients. A pub needs to count kegs, monitor pour rates, track what’s in lines, and account for spillage and wastage. The systems are completely different, and trying to force a food venue model onto a wet-led pub is where most landlords run into trouble.

The Three Components of Effective Bar Stock Control

Effective bar stock control has three parts, and they have to work together. Miss one and the whole thing collapses.

1. Accurate Physical Counts

You need to know exactly what you have in stock at a known point in time. Not an estimate. Not “about three kegs of lager.” Exactly three kegs, weight and volume if you have scales. Bottles counted individually. Optics checked for content. This is the only number you can trust because you’ve actually seen it.

For draught product, this means checking cellar stock (full kegs, part-used kegs, kegs on the line) and measuring pour rates. If a keg should yield 140 pints and you’ve sold 120 pints according to till records, you should have the equivalent of 20 pints still in that keg. If you don’t, something’s wrong — either the till data is wrong, or you lost product somewhere.

Most pubs count stock once a week. That’s the minimum. If you’re serious about controlling waste and spotting theft, you count twice — a full count on Tuesday or Wednesday when business is slow, and a spot check on Saturday night checking just high-value items (spirits, premium draught, wine).

2. Reliable Till Data

Your EPOS system — or till, if you’re still using a traditional register — has to record every single transaction accurately. Not “approximately.” Not “we usually ring things in.” Every pint, every spirit, every soft drink. This is harder than it sounds because it requires staff discipline and training. A busy Saturday night with three people behind the bar is exactly when accuracy drops. That’s also when discrepancies build up fastest.

The problem with traditional tills is that they don’t talk to your stock system. You take a reading Tuesday morning, and then you have no idea what should have been sold until you count again next Tuesday. That’s a seven-day blind spot. An EPOS system comparison for UK pubs will show you that the best systems integrate stock directly, so you can see in real-time whether today’s actual sales match till records.

3. Regular Reconciliation

Take your physical count. Compare it to what the till says you should have sold. Find the gap. That’s reconciliation. If counts and till data match, you’ve got integrity. If they don’t, you need to find out why before you count again.

The gap usually sits between 3–5% in a well-run pub. That’s spillage, sampling, a drink that wasn’t rung in, a customer complaint where you remade a pint. It’s normal. If your variance is 8–12%, you’ve got a training problem or a behaviour problem. If it’s above 15%, you’ve got a serious issue.

Setting Up Your Stock Count System

The most effective bar stock control system in UK pubs uses three separate counts: draught product, spirits, and everything else. Each requires different methods because the products behave differently.

Draught Product Stock Count

Draught is the hardest to count because it’s invisible. You can’t see how much is in a keg. You have to calculate it. Here’s how:

• Record the weight of each keg on hand (full kegs should be marked with their weight)
• Calculate how many pints are in each keg using the keg size (a standard keg yields approximately 140 pints)
• Track pour rates from your EPOS — if you’ve sold 120 pints of lager this week, divide by the number of keg units you have on line to estimate what should be left
• Physical check: is the line pressure correct? Are there any leaks? A keg that should have 20 pints left but has 10 means you’ve lost product in the line
• Record any spillage or waste separately — this goes into the “expected loss” category, not the “variance” category

When I set this up at Teal Farm, I created a simple spreadsheet with columns for keg type, keg number, weight, date checked, till sales for the week, and variance. Every Tuesday morning I weigh the kegs, check the numbers, and flag any line that looks wrong. If a keg shows 15 pints missing and I only sold 5, something in the line is broken or leaking. That’s a maintenance issue, not a stock issue.

Spirits and Premium Products

Spirits are the opposite of draught — they’re easy to count but high value. Measure bottle contents with a jigger or optic. A standard optic pour is 25ml or 35ml. If you’ve sold 20 measures of vodka according to till, and you have one fewer bottle than you started with, that’s correct. If you have two fewer bottles, you’ve got a variance of one bottle.

This is where theft usually shows up. High-value products in plain sight. A bottle a week going missing doesn’t sound like much until you do the maths — that’s £1,200 a year from a single spirit. That’s why Saturday night spot checks matter. You check spirits every Saturday at the end of the night, and you compare to till sales for that day only. If the numbers don’t match, you know it happened today, not sometime in the previous week.

Beer and Soft Drink Stock

Bottles and cans are straightforward — count them. Use your EPOS to know what should have sold, compare to the count. The variance here is usually low because it’s easy to audit. If you’re finding big discrepancies in bottle stock, look at your staff. Are they opening bottles and not ringing them in? Are they using them to top up drinks? Are they giving them away?

Integrating EPOS with Stock Management

A modern EPOS system is the single biggest upgrade you can make to bar stock control. I say this as someone who ran stock control manually for three years. I understand why pubs stick with old tills — the switching cost feels high, and if the current till “works fine,” why bother?

Here’s why you should bother: An EPOS system with stock integration will reduce stock variance by 2–3 percentage points within the first month, which translates directly to margin improvement. On a £5,000 weekly bar take, that’s £100–150 a week. That’s £5,000–£7,500 a year. And that’s just from the variance reduction — you also save staff time and eliminate guesswork.

When evaluating wet-led pub EPOS solutions, look for these specific features:

• Real-time stock tracking — you should be able to see current stock levels at any time, not just at count time
• Integration with draught system — the system needs to track keg usage and estimate pour rates
• Variance reporting — the system flags discrepancies automatically so you don’t have to hunt for them manually
• Staff accountability — you need to know which staff member rang in which transaction so you can trace issues back to individual behaviour
• Offline capability — if your internet goes down, the till still works and syncs later (this matters more than you think on a Saturday night)

When we were testing systems at Teal Farm, the real test came on a Saturday night with a full house. Three staff behind the bar. Card-only payments. Kitchen tickets running. Tabs for the quiz team. Most systems that look perfect in a demo fall apart when three people are hitting the same terminal at once during last orders. The EPOS we chose handled it, and just as importantly, it gave us a clear record of what was rung in, what was sold, and what the variance was by 10 p.m. that same night. That’s not possible with a traditional till.

One warning: The real cost of an EPOS system isn’t the monthly fee — it’s the staff training time and the lost sales during the first two weeks. Your speed of service will drop. Your accuracy will initially dip. Staff will get frustrated. You’ll question your decision. This is completely normal and temporary. Budget two weeks for proper pub onboarding training and accept that your numbers will be messy during that period. By week three, you’ll be faster and more accurate than before.

If you’re tied to a pubco, check their compatibility requirements before buying any EPOS. Some pubcos only allow certain systems, or they require integration with their own stock management platform. This is a non-negotiable check — you could spend £2,000 on a system only to find out your pubco won’t support it.

Finding and Fixing Stock Discrepancies

When your count doesn’t match your till data, you have a variance. The first question is always: how big is it? The answer determines what you do next.

Stock variances below 3% in a wet-led pub are normal and expected — they represent spillage, sampling, comped drinks, and measurement error that is unavoidable even in a well-controlled system. Don’t chase these. Accept them as part of cost of goods sold.

Variances between 3–8% mean something is slightly wrong. You have a training issue or a process issue. A staff member is occasionally forgetting to ring things in. Someone is topping up drinks without entering them. A line is leaking slowly. These issues are fixable with training and process tightening.

Variances above 8% indicate a serious problem. Either you have systematic staff behaviour you need to address, your till data is unreliable, or you’re losing product through theft or waste that you don’t understand. This requires investigation.

How to Investigate Variance

Start with till audit. Print till rolls for the period in question. Do a spot check: pick 20 transactions at random and verify that the product was actually sold (ask the customer, check the glass, verify it was consumed). If till data is accurate, move to the next step.

If till data is unreliable, that’s your problem. You need staff retraining. Every shift before service, remind staff: if you pour it, you ring it. No exceptions. No “I’ll add it to the tab later.” No “I’m too busy right now.” Ring it when you pour it. That one rule eliminates 80% of variance issues.

If till data is accurate but stock count is wrong, you have a loss problem. Is it spillage? Ask staff — they’ll know. Is it an unmeasured loss in a line? Check line pressure and condition. Is it going down the drain during cleaning? Train staff on efficient cleaning. Is it being given away? This is where you need to look harder, because this is the only point where dishonesty usually enters the picture.

Use your pub profit margin calculator to model what the impact of variance is in pounds. If you’re losing 5% of stock value and your weekly bar take is £5,000, that’s £250 a week, or £13,000 a year. That’s a real number. That gets people’s attention, including your own staff’s attention. Show them the maths. Tell them: this is the difference between a pub that survives and one that closes.

Stock Control for Wet-Led vs Food-Led Pubs

Wet-led pubs and food-led pubs need completely different approaches to stock control. Most comparison websites and consultants miss this entirely. They give generic hospitality advice that works equally well for a restaurant as a pub. It doesn’t.

Wet-Led Pub Stock Control

Wet-led pubs (your Teal Farm model — high volume of draught, spirits, and bottles with minimal food) have one critical challenge: draught product loss happens in real-time and is almost impossible to audit after the fact. You pour a pint at 9 p.m. on a Saturday. By the time you do your count on Tuesday, that transaction is five days in the past. You can’t see it anymore. You can only see the maths: if your till says you sold 400 pints of lager and you started with 8 kegs and ended with 5 kegs, those numbers should match perfectly. If they don’t, something happened in those three kegs that you can’t recover by looking at them Tuesday morning.

This is why regular spot checks matter so much in wet-led pubs. Check high-value draught on Saturday and Sunday night, right after service. You’re checking the system when it’s fresh and staff can still remember what happened.

Wet-led stock control also requires strict discipline around free pours and comps. In a food venue, a free item is easily tracked because the kitchen records it. In a pub, a free pint is poured by a member of staff, served, and consumed. Nobody writes it down. But you need to know it happened so you can account for it. Create a “void” or “comp” transaction type in your till. Every free drink gets logged. This takes 15 seconds. It solves half your variance problems immediately.

Food-Led Pub Stock Control

Food-led pubs have lower draught volumes and higher inventory complexity because they’re managing food, drink, and mixed product. Stock control is easier in one way — more of your inventory is on the shelf and can be counted — but harder in another way because you’re managing more SKUs (stock keeping units) and the kitchen is using stock that doesn’t go through the till.

In a food-led pub, you need to track food waste separately from drink waste. You also need to know what the kitchen is using. If the till says you sold 20 fish and chips but the kitchen used 25 portions of fish, you have a 5-portion variance. Where did it go? Comped? Dropped on the floor? Given away? You need to understand the difference.

Use your pub staffing cost calculator to factor in the cost of a dedicated person doing stock reconciliation. In food-led pubs, this person often exists. In wet-led pubs, it’s usually the landlord or manager doing it in addition to other duties. If your pub is big enough to justify a dedicated stock controller, the cost is worth it because the accuracy improvement pays for itself.

Bar stock control is one of those things that feels tedious until you realise how much money it’s costing you. Once you’ve got a system that works — accurate counts, reliable till data, regular reconciliation — it becomes automatic. You spend 2–3 hours a week on stock management instead of 5–6. You know your numbers. You spot problems early. Your margins improve.

That’s the real win. Not perfection. Not a zero variance. Just knowing your business well enough that you can make decisions based on facts instead of guesses. That’s what separates pubs that survive from pubs that struggle.

The next step is choosing the right pub management software to make this systematic and automatic. Don’t overthink it. Look for real-time stock tracking, draught integration, and variance reporting. Test it during a busy service. Check compatibility with your pubco if you’re tied. Then commit to the implementation and give your staff proper training.
