Pub EPOS with Cellar Management: Brulines & Vianet Explained

Last updated: 23 April 2026

Most pub landlords assume their EPOS system and cellar management are separate problems that need separate solutions. They’re not. When your till doesn’t talk to your stock, you’re paying twice: once in software, once in wasted labour counting bottles by hand. But here’s what catches most operators off guard—cellar integration isn’t just a feature tick box. It’s a compatibility minefield, especially if you’re a tied tenant on a pubco like Marston’s. Choose the wrong system, and you’ll be locked into a 24-month contract with an EPOS that won’t sync with your tied supplier’s pour systems.

The real question isn’t whether you need cellar management integration. The question is whether your EPOS system will actually work with Brulines, Vianet, or whatever your pubco requires. During a Saturday night at Teal Farm—180 covers, kitchen orders flying, bar tabs running on three terminals simultaneously—we learned that integration isn’t about having nice data. It’s about knowing exactly what you’ve poured, what you’ve sold, and whether the numbers match before the auditor arrives.

This guide breaks down what cellar management integration actually does, why Brulines and Vianet matter for tied tenants, the real total cost of implementation, and the compatibility questions you need to ask before signing any EPOS contract.

What Cellar Management Integration Actually Is

Cellar management integration means your EPOS system automatically records what was poured and compares it to what was sold, flagging discrepancies in real time. Without it, you’re relying on manual stock takes, which are slow, error-prone, and often happen only once a week.

Here’s how it works in practice. Every drink poured through a connected optic or pump is logged by the cellar system. Your EPOS records every sale. Integration software pulls both datasets together and produces a variance report—the difference between what you poured and what you charged. A 2% variance is normal (spillage, training mistakes, samples). Anything above 5% means you have a problem: either systematic undercharging, staff theft, or faulty equipment.

Without integration, you won’t know about a 10% variance until your monthly stock take, by which time you’ve already lost £400 in a 180-cover pub. With integration, you know by Tuesday morning and can address it before the week is out.

The operational benefit isn’t the data itself. It’s the speed. You stop counting stock by hand. You stop cross-referencing invoices with till reports manually. Your cellar team spends 30 minutes a day checking an exception report instead of four hours a week taking physical stock. That’s roughly 12 hours of labour saved per week—at £12/hour, that’s £600 a month in saved wages.

Why This Matters for Wet-Led Pubs Specifically

Food-led pubs can get away with weekly stock takes. Their variance is naturally lower because food waste is more visible and controllable. A wet-led pub—especially one with spirits and premium lagers—has higher daily variance naturally. At Teal Farm, we sell roughly 40% of our revenue through draught systems, where every pour is theoretically trackable. If you’re not tracking it, you’re flying blind on 40% of your turnover.

Most generic EPOS comparison sites treat this as a nice-to-have feature. It’s not. For wet-led operators, cellar integration is the difference between managing profitability and guessing.

Brulines vs Vianet: The Difference That Matters

Brulines and Vianet are not competitors in the way that Epos Now and ICRTouch are. They are tied supplier systems—each one belongs to a different pubco network, and your EPOS must be certified to work with whichever one your pub is connected to.

Brulines: Marston’s, Enterprise, and Independent Pubs

Brulines is the cellar management system used by Marston’s (the largest pubco in the UK), Enterprise Inns, and various independent estates. It’s been around since the 1990s and is the most widely installed pour-level system in UK pubs. If you’re a Marston’s tenant—as we are at Teal Farm—your cellar is almost certainly fitted with Brulines hardware (optics, pump counters, and a central monitoring unit).

Brulines doesn’t just track pours. It also monitors temperature, CO2 levels, and line cleaning cycles. These aren’t optional extras for compliance—they’re required. The EHO and your pubco audit these records. Without integration to your EPOS, you’re maintaining Brulines data in isolation, which means you’re creating two separate records: one for the auditor and one for running your business.

Brulines integration means your EPOS automatically pulls pour data from the Brulines unit every night. You no longer need to log into Brulines separately to check variance. You don’t need to manually export reports and reconcile them with your till. It’s automatic.

Vianet: Star Pubs, Greene King, and Others

Vianet is the competing pour-level system, predominantly used by Star Pubs (Heineken’s pub division) and some independent estates. It serves the same function as Brulines—tracking pours, temperatures, and compliance data—but it’s a different technology platform with a different API.

An EPOS system certified for Brulines integration may not be certified for Vianet, and vice versa. This is not a minor technical detail. This is a contract-breaking issue. If you’re on Vianet and you install an EPOS that only integrates with Brulines, your pubco could argue that you’ve breached your tenancy agreement by failing to maintain the audit trail they require.

We’ve seen this happen. One operator switched from an integrated Brulines-compatible system to a cheaper EPOS that had “cellar management” as a feature—but it turned out the feature only worked with generic systems, not Brulines specifically. Eight weeks later, they were forced to upgrade again because their Marston’s agreement required Brulines integration for audit purposes.

The Real Difference

From an operator’s perspective, Brulines and Vianet do almost the same thing. The difference is which pubco you’re tied to. It’s like asking “what’s the difference between a Visa card and a Mastercard?” From your pocket, they’re almost identical. But if the shop only takes Visa, it doesn’t matter how good Mastercard is.

Why Integration Matters for Tied Tenants

If you’re a free house, cellar integration is a business efficiency choice. If you’re a tied tenant, it’s often a contractual requirement.

Tied pubs operate under specific agreements with their pubco. These agreements typically include:

• A requirement to use the pubco’s approved cellar system
• A requirement to maintain specific audit trails for EHO and tax purposes
• A requirement that your EPOS system must integrate with the cellar system, not run separately

This last point is buried in most tenancy agreements in language like “the licensee shall ensure that all beverage management systems are integrated and maintained to pubco audit standards.” Most tenants don’t read this carefully until they’re six weeks into a new EPOS installation and their pubco tells them it’s not compliant.

At Teal Farm, we’re a Marston’s CRP (Community Retail Partnership) pub. Our tenancy agreement explicitly states that our EPOS must support Brulines data capture for audit purposes. When we selected our system, we didn’t just ask “does it have cellar management?” We asked Marston’s directly: “Is this EPOS on the approved list for Brulines integration?” The answer was yes, in writing, before we signed the contract. This matters.

If your EPOS isn’t integrated with your pubco’s cellar system, you have two options: upgrade the EPOS (expensive) or downgrade your cellar system (not an option—it’s in your agreement). The cost of getting this wrong is 12-24 months of non-compliance and potential termination notices.

This is something most generic EPOS comparison sites completely miss. They’ll compare features and prices, but they won’t tell you that your Dream EPOS system isn’t on your pubco’s approved compatibility list.

The Real Total Cost (Beyond Monthly Fees)

The sticker price of an EPOS system with cellar integration is usually quoted as a monthly fee: £49, £79, £129. These quotes are misleading because they exclude the real cost of integration, which typically runs 40-60% higher than the software cost itself.

Hardware Costs

If your cellar doesn’t already have pour-level tracking hardware installed (optics, pump counters, line monitors), you’re installing that too. Brulines hardware costs roughly £1,500–£3,000 depending on the number of taps and the age of the existing setup. This isn’t optional if you’re a tied tenant—it’s required. But most EPOS providers quote only the till and software, and pubcos often quote hardware separately or expect you to have it already.

Total hardware: £1,500–£3,000 (one-time, or amortised over 5 years)

Installation and Integration Setup

Installing an EPOS isn’t a plug-and-play operation when cellar integration is involved. The system needs to be physically connected to your Brulines (or Vianet) unit, API access needs to be configured, and test runs need to be performed. Most providers charge £400–£800 for this work. Some include it in their package; most don’t.

Total installation: £400–£800 (one-time)

Staff Training (The Hidden Cost)

This is where most operators get blindsided. Your staff aren’t just learning a new till system. They’re learning how to:

• Use the EPOS for sales entry (straightforward)
• Understand what the cellar integration is doing (confusing for most staff)
• Troubleshoot basic connection issues (they’ll need to)
• Read variance reports and flag discrepancies (new responsibility)

A typical training programme is 4–6 hours for basic operation, plus 2–3 follow-up sessions over the first two weeks. If you have 8 staff and they’re paid at £12/hour, that’s roughly £480–£720 in wages for training time, plus lost productivity during the first week (expect 10-15% slower service while staff get comfortable).

Total training cost: £480–£1,200 (plus lost sales, typically £200–£400 in a 180-cover pub)

Data Migration and Reconciliation

If you’re switching from an old system, someone needs to migrate historical data, reconcile existing stock levels, and ensure the new system starts clean. This sounds simple but typically takes 8–16 hours of work at £20/hour (you or an external consultant).

Total data migration: £160–£320 (one-time)

First-Month Downtime and Adjustment

Most integrated EPOS systems have a learning curve where the cellar integration data is wonky for the first 2–4 weeks. Variance reports don’t match. You’re not sure if the system is wrong or your staff are. You’re often reconciling manually anyway, defeating the purpose.

This typically costs £300–£500 in labour as you spend extra time troubleshooting. It’s not glamorous, but it’s real.

Total adjustment period cost: £300–£500 (one-time)

The Real Total Cost (Year 1)

A system quoted at £79/month looks like £948 per year. In reality, you’re looking at:

• Monthly software: £948
• Hardware (one-time): £2,000
• Installation: £600
• Training and productivity loss: £1,200
• Data migration: £240
• Adjustment period: £400

Year 1 total: approximately £5,388

That’s £449/month when you spread it across 12 months, not £79. And that’s assuming no major issues. If you need hardware repairs or additional training, add another £200–£400.

When you run these numbers against labour savings (roughly £600/month in manual stock-take time), the payback period is 8–10 months. After that, you’re saving money. But you need to know the real cost before you commit to a 24-month contract.

Compatibility Checklist: Questions to Ask Before Signing

Before you sign a 24-month EPOS contract, you need answers to these questions in writing. Not verbal promises. Written confirmation from the EPOS provider.

1. Which Cellar Systems Are You Certified For?

Ask the EPOS provider directly: “Are you certified for Brulines integration, Vianet integration, or both?” If they say “we support cellar management” without specifying the system, they’re being deliberately vague. Push for specifics.

If you’re a Marston’s tenant and they say they only integrate with generic systems, walk away. You’ll be non-compliant within six months.

2. Is Integration Included in the Monthly Fee or Charged Separately?

Some providers include cellar integration in their base package. Others charge £15–£25/month extra for it. If it’s extra, it needs to be in writing as part of your quote. You don’t want to discover this three months in when you ask them to activate the integration.

3. Will Your Pubco Approve This System?

If you’re a tied tenant, contact your pubco directly before signing. Ask them: “Is this EPOS on your approved list for [Brulines/Vianet] integration?” Get their answer in writing. If they say “we don’t maintain an approved list,” ask them what happens if the system doesn’t integrate properly. The answer should be “we’ll work with you to fix it” not “that’s your problem.”

We did this at Teal Farm with Marston’s. They sent us an approval email within 48 hours. It took five minutes and saved us a potential £3,000 mistake.

4. What Happens if Integration Fails During the Contract Period?

Ask in writing: “If the cellar integration fails or becomes non-compliant with [pubco] requirements, what is your support SLA? Who pays for fixing it? Can I exit the contract early without penalty?”

Most contracts are silent on this. You want clarity upfront.

5. What Training and Support Is Included?

Cellar integration isn’t intuitive for staff. Is training included, or is it £100–£200 per staff member? Are follow-up sessions included if something breaks? Do they have a helpline, email support, or both?

6. How Often Does the Cellar Data Sync?

Real-time sync is a lie. No system syncs truly in real time. Most sync every 2–4 hours or once daily. If your EPOS says “real-time cellar integration,” ask them to define it in writing. If it’s actually 4-hour batch syncs, you need to know that before you depend on variance data for daily management.

7. What’s the Contract Break Clause?

This is the most important question. If the system doesn’t work, or your pubco says it’s not compliant, can you exit early? Most 24-month contracts have break clauses at 12 months with 30 days’ notice and no penalty. Some don’t. If there’s no break clause, you’re locked in regardless of what happens.

No break clause? Don’t sign.

Implementation Reality: What Actually Happens

Here’s what really happened when we integrated Brulines with our EPOS system at Teal Farm. This is the experience most operators don’t read about before they commit to a contract.

Week 1: Installation and Initial Setup

The hardware installer arrived on a Tuesday morning (off-peak). They took 3 hours to run network cables from the Brulines unit in the cellar to the bar system, test the connection, and verify data flow. The install team was professional and created minimal disruption. Cost as quoted: £600. Actual cost: £600. (We were lucky—some installations overrun by £200–£300.)

That afternoon, the EPOS provider sent an engineer to configure the integration. They needed access to our Brulines login and our EPOS admin credentials. The configuration took 1.5 hours. They explained what they were doing, but it was technical and our staff wouldn’t have understood it anyway.

Week 2: Staff Training (Chaotic)

We ran four 90-minute training sessions across two days. Our eight bar staff attended in two groups. The trainer explained:

• How to navigate the EPOS (familiar to most staff from the demo)
• How to read a variance report (new and confusing)
• What to do if the till and cellar numbers don’t match (troubleshooting steps)
• Where to find the integration log if something breaks (too technical for most staff)

By the end of training, about 60% of our staff understood the concept. 40% nodded along and forgot it immediately. This is normal.

We also lost productivity that week. Service was 10-12% slower. Mistakes happened (wrong items rung, incorrect modifiers). This is expected but still costs money—we estimate £250 in lost revenue that week.

Week 3-4: The Wobble

The variance reports started coming through. On day one, the report showed a 3.2% variance on draught lager. That was normal. On day four, it showed 8.1% variance on whisky. That set off alarm bells.

We thought there was a system problem. The EPOS provider thought we had a stock discrepancy. It turned out we had both: the system wasn’t reading one of the optics properly and our staff were undercharging for double shots during a training period when they were distracted. Once we fixed the optic calibration, the variance dropped to 2.1% and stayed there.

This troubleshooting took about 4 hours of our time plus 2 hours of the provider’s time. Most of this happened during operational hours because we’re too busy during the day to do extensive testing.

Week 5 Onwards: Business as Usual (But Better)

By week 5, the integration was reliable. Every morning, a variance report landed in our inbox. It took 10 minutes to review. Issues that used to take a day to diagnose now took 15 minutes. Stock discrepancies that used to accumulate over a month were caught within 48 hours.

The real win came in month two. We identified that our draught system was over-pouring by about 0.3 oz per pint—completely undetectable without pour-level data. We adjusted the flow rate, and our draught margin improved by 1.2 percentage points. In a 180-cover pub with 40% draught sales, that’s roughly £60–£80 per week in recaptured profit. We’d made back the entire installation cost in 10 weeks.

What We Wish We’d Known

The implementation itself was straightforward compared to the operational adjustment. Integrating cellar data into daily management is a mindset shift, not just a software change. Your cellar manager and head bartender need to become amateur data analysts overnight. This takes longer than expected and requires more training than vendors typically quote.

Also, the first variance report will always feel wrong. Your staff will have done things slightly wrong for months, and suddenly the system is catching all of it. Expect staff friction and take time to investigate discrepancies calmly rather than assuming the system is broken.

If you’re a tied tenant, confirm with your pubco that the integration is working properly once you’re live. We sent Marston’s a sample variance report in week 3 to confirm it met their audit requirements. It did, but they caught a formatting issue that we fixed before it mattered.

The Bottom Line: Is Cellar Integration Worth It?

For a wet-led pub doing 150+ covers with significant draught sales, cellar integration pays for itself in 8–12 months through labour savings and margin recovery. For a small free house doing 60 covers, the ROI is much slower—probably 18–24 months.

But this isn’t just about ROI. If you’re a tied tenant, cellar integration isn’t optional. It’s a compliance requirement buried in your tenancy agreement. The question isn’t whether to integrate. The question is whether your EPOS provider is certified with your pubco’s system before you sign.

The operators who have problems are the ones who:

• Install an EPOS that claims to have “cellar management” without verifying it’s compatible with their specific pubco system
• Underestimate the real total cost beyond monthly fees
• Don’t confirm pubco compatibility in writing before signing
• Expect staff to manage variance data without proper training

If you get these four things right, cellar integration will transform how you manage your pub. If you skip any of them, you’ll be frustrated and out of pocket.
