Lightspeed Restaurant Inventory Review for Pubs
Last updated: 26 June 2026
Most restaurant inventory systems are built for food cost management, not for a pub’s unique nightmare: tracking a cask that’s half-empty, a spirit bottle with 10 different pours logged, and draught lines that lose product to temperature swings and poor cleaning.
Lightspeed Restaurant is a capable point-of-sale and inventory platform—I’ve seen it work well in casual dining chains and QSR operations. But it was designed for a kitchen inventory problem, not a cellar management problem. If you’re a pub licensee evaluating Lightspeed for stock control, you need to know exactly what it can and cannot do, and where the gaps are that cost you money.
I’m going to give you an honest assessment based on 15 years running a Marston’s pub and helping other licensees claw back money they’re losing to poor stock discipline. This isn’t a generic software review—it’s what a working pub operator needs to know before committing budget to a system.
Key Takeaways
- Lightspeed Restaurant is a solid general inventory system for food businesses but lacks the specialist tools pubs need to track cask depth, spirit bottle weight, and cellar temperatures.
- A 1% stock loss on wet sales quietly costs a typical pub £3,000–£5,000 a year, and Lightspeed alone won’t catch it because it can’t see what’s actually in your bottles and casks.
- Pubs need weekly physical counts tied to till data on the same day; Lightspeed is built for periodic cycle counts and food variance, not the disciplined wet stock routine that stops shrinkage.
- If you’re serious about stock control, you need a system designed by someone who has actually run a pub cellar, not a general restaurant platform adapted for licensed trade.
What Is Lightspeed Restaurant?
Lightspeed Restaurant is a cloud-based EPOS and inventory management platform. It integrates sales data with stock tracking, shows you what sold via the till, and lets you log physical counts to spot variances. The premise is sensible: reconcile what your system says you sold against what actually left the cellar and bar.
For restaurants and casual dining, this works reasonably well. Food items come in fixed packaging, shelf life is measurable, and waste is usually visible and easy to account for.
But a pub’s inventory problem is fundamentally different. Spirits live in open bottles. Draught kegs are measured by dip, not by consumption. Wine is poured in different measures. Temperature, line cleanliness, and human measurement error don’t exist in a kitchen inventory system.
What Lightspeed Does Well
Sales Integration
Lightspeed’s core strength is that it talks to your till. When you ring a pint or a spirit, the system logs it. You can then manually count stock and compare actual versus expected. In theory, that variance tells you where shrinkage is happening.
For packaged goods—bottled beers, crisps, pre-made products—this works fine. You know a case of lager came in with 24 bottles. You sold 20. There should be 4 left.
Reporting and Dashboard
Lightspeed gives you visibility into stock value, cost of goods sold (COGS), and inventory turnover by category. You can see trends and compare periods. For a pub manager trying to understand the shape of the business, that’s useful context.
Multi-Location Support
If you run multiple pubs, Lightspeed can track across all of them from one dashboard. That’s operationally convenient.
The Critical Gaps for Pub Operators
No Cellar-Specific Measurement Tools
Here’s the painful truth: Lightspeed doesn’t know the difference between a full cask and a half-empty one unless you manually measure it with a separate dipstick and tell the system. It assumes that if you didn’t log a count, the cask is still at whatever level you last logged. That’s a recipe for invisible shrinkage.
A proper pub stock system needs to show you: cask depth, partial keg status, spirit bottle weight, and cellar temperature. Not as separate paperwork that you then input—as live data that sits in the same interface where you reconcile against sales.
Open-Bottle Measurement Is Manual and Unreliable
When I was running my stock on a tangle of spreadsheets, I discovered that spirits hide more loss than anything else. A free-poured 25ml measure is often 32–35ml in reality. A bottle that “should” have 30 measures left might genuinely have only 22, because nobody’s been weighing it.
Lightspeed has no built-in feature to weigh open spirit bottles or flag when a bottle is drifting from expected to actual. You have to do that manually, off-system, then reconcile by hand. Most pub managers don’t bother—and that’s where £50 to £100 a week walks out of the door.
Draught Loss Is Invisible
Draught beer loss comes from three places: poor line temperature, bad line cleaning (product sits in pipes, goes flat, gets run off), and measurement error (the till ring doesn’t match what actually came out). Lightspeed can’t see any of that. It just knows you rang 40 pints and you should have lost 4 gallons. Whether you actually lost 4 or 6 gallons is unknown.
A cellar-aware system would flag draught variance by line, show you temperature logs, and alert you when one line is running higher loss than its peers. Lightspeed does none of that.
Weekly Reconciliation Is Clunky
The number that actually matters for a pub is wet GP by line, not a single headline stock figure. Spirits hide losses in over-pouring. Draught hides it in poor cellar management and waste. To catch it, you need to weigh open spirit bottles, dip every cask and partial keg, and reconcile against till data the same day.
Lightspeed is designed for periodic cycle counts—you count stock every 2–4 weeks, log it, and see the variance. That’s a restaurant rhythm. Pubs need a weekly rhythm. The longer you wait between counts, the harder it is to find the leak.
No Temperature or Humidity Tracking
A cask stored at 15°C lasts longer and pours better than one stored at 18°C. Poor cellar temperature costs you product life and waste. Lightspeed doesn’t measure, log, or alert on cellar conditions. It’s not designed to.
Cost and Setup
Lightspeed Restaurant pricing varies by tier, but you’re typically looking at £200–500+ per month depending on features and transaction volume, plus setup, training, and hardware integration. If you already have a capable till (which many pubs do), adding Lightspeed inventory on top is an extra layer of cost and complexity.
For a typical pub turning £500k–£1m annually, that’s a meaningful cost. And if it doesn’t solve your actual stock control problem, you’ve just spent money on reporting instead of prevention.
Better Alternatives for UK Pubs
Purpose-Built Pub Inventory Systems
There are systems designed specifically for pubs that do the things Lightspeed doesn’t: cellar temperature monitoring, cask depth logging, spirit bottle weighing, draught line variance by product, and weekly reconciliation against till data in a single workflow.
These systems cost less than Lightspeed, require less setup, and are built by people who understand that a pub’s inventory problem is not the same as a restaurant’s.
The StockTap pub stock app is one example—a purpose-built tool created by a working pub landlord for exactly this purpose. It handles cask dips, spirit weights, temperature logs, and weekly reconciliation against till data, all in one interface. No subscription, no monthly fees, just a one-time cost of £97.
Spreadsheet Plus Discipline
I know that sounds counterintuitive coming from a software company, but it’s true: a well-structured spreadsheet plus a disciplined weekly counting routine will catch more stock loss than Lightspeed will, because you’ll actually do the weekly count. I built a simple count routine around a dipstick and a set of scales, and the weekly variance went from guesswork to a number I could trust within a fortnight. Most pubs that move from a messy spreadsheet to a disciplined count claw back 1–2 gross profit points within a couple of months.
Lightspeed is better than a messy spreadsheet. But a disciplined routine with a pub-specific tool beats Lightspeed every time.
The Honest Verdict
Lightspeed Restaurant is not built for pub stock control. It’s a restaurant inventory system that can technically be used in a pub. But it will cost you more money and give you less insight than a system designed for the actual problem pubs face.
If you already use Lightspeed for your general EPOS and you want inventory reporting on top of it, it works—it’s a capable platform and the reporting is solid. But don’t buy Lightspeed specifically to solve your stock shrinkage problem. It won’t.
The pubs that claw back money from stock losses do so because they:
- Count wet stock weekly, not every four weeks
- Weigh open spirits and dip every cask the same day, every week
- Reconcile variance against till data immediately, while memory is fresh
- Treat stock control as a discipline, not an afterthought
You can do all of that with Lightspeed, but the system doesn’t make it easy or natural. It’s designed for a different workflow.
If you’re serious about stopping the £3,000–£5,000 a year that a 1% stock loss quietly costs, use a system built by someone who actually runs a pub cellar. The difference in outcome—and in your bottom line—will be measurable within weeks.
