Running a Bar: The Reward and the Risk
Running a bar can be one of the most rewarding—and one of the most punishing—jobs in the hospitality industry. When it’s good, it’s magic: loyal regulars, a strong team, money in the bank. But when it’s not? You’re losing sleep, losing staff, and watching money leak out of your business with no idea where it’s going.
What Really Sets Successful Bars Apart
So what separates the long-term success stories from the struggling venues in the bar business? And how do they provide & increase customer satisfaction?
It’s not luck. It’s not location. It’s not being the cheapest place in town or having the most Instagrammable cocktails.
It’s systems. Accountability. Consistency. Leadership. And a clear understanding of how to run the business side of things without losing sight of the people who make it work.
A successful bar is good for business—but it’s also good for the people in it.
Good for the bar staff who feel supported and proud of their work.
Good for the guests who find their “third place”—that local spot where they feel seen, welcome, and part of something.
Good for the neighborhood that comes alive when the lights go on.
This guide breaks down what it really takes to run a successful bar—from inventory and staffing to service, culture, and profit.
But before we get into the how-to, let’s start with some eye-opening numbers:
- Most bars aim for a profit margin between 15% and 30%, but hitting that range requires precision. At the same time, U.S. bars lose 20–25% of their inventory every week—often due to a range of issues. Some are intentional, like outright theft or bartenders pouring doubles for friends. But more often, the losses are unintentional: unrecorded comps, draft waste, inconsistent pouring techniques, or inaccurate inventory counts.
- Many bars aim for a pour cost around 20%, depending on concept and product mix. But pour cost only tells part of the story. It shows what you spent—not what you should have spent. To uncover lost profits, you need to look at variance: the gap between what was sold and what was actually used. That’s where waste, theft, and missed revenue hide.
- Labor and food costs continue to be major pressure points for bar and restaurant owners. Labor alone often makes up 30–35% of revenue. And while staffing used to be the top concern, many operators now say food inflation has taken the lead—squeezing margins from both ends.
- Despite the challenges, the sector is growing: bars and nightclubs in the U.S. have seen a 2.4% annual growth rate over the past five years. And in 2025, bars are still holding strong with gross profit margins between 72% and 82%—outpacing many other industries.
1. Get the Basics Right: Service, Product, and Atmosphere
Let’s start with the fundamentals in the hospitality industry. You can’t build a great bar on gimmicks. The foundation of every successful bar is simple: great service, a quality product, and a welcoming atmosphere.
Great service—exceptional customer service—doesn’t happen by accident. It’s purposeful, and it’s accomplished through training, clarity, and repetition. Your guests should feel just as cared for on a busy Saturday night as they do on a "normal" Tuesday.
Product goes beyond what you serve: they are not just menu items with their prices. It's about how you serve your offerings. A cocktail made with care, a properly poured beer, pristine glassware—these details add up. If you’re not checking your pours, garnishes, or prep standards,
you’re leaking money and damaging your brand. Every drink should feel intentional.
Atmosphere is often the invisible difference between a quick drink and a full tab. It includes everything your guests experience that isn’t poured or plated—cleanliness, music, lighting, comfort. As someone once said,
“People may not remember what you said, but they’ll remember how you made them feel.”
Creating a good atmosphere can greatly inmprove customer experience.
When the lights are harsh, the music’s overwhelming, or the space feels neglected, guests won’t stick around. The environment should invite people in—not push them out. Customer retention is about providing the best customer experience possible—every guest, every time.
A well-tuned atmosphere invites people to stay longer, spend more, and come back (with friends). It all adds up to providing an excellent customer service.
Successful bars get these fundamentals right every single shift. Because that’s what earns trust, builds loyal customers, and keeps the bar full—on Tuesdays and Saturdays alike.
2. Know Your Numbers
You can't manage what you don't measure.
One of the fastest ways to fail is to focus only on sales. Revenue is important, sure—but profitability is what keeps your doors open. So, you need to keep track of inventory levels.That’s where knowing your numbers comes in.
Let’s break that down.
a. Cost of Goods Sold (COGS)
COGS is the percentage of your revenue that goes toward the products you sell—beer, liquor, wine, food, etc. It’s one of the clearest indicators of how efficiently you’re operating— your food cost, your beverage cost, and how much profit margin you’re keeping.
But to really understand your performance and operational costs, you need more than just a monthly snapshot. Monthly inventory alone isn’t enough. A lot can slip through the cracks in 30 days. That’s why it’s important to track COGS weekly—and track your weekly inventory right—so that you know your bar profit margins.
b. Depletion and Variance
Let’s clear something up: depletion is not the same as sales—and it’s definitely not the same as variance or shrinkage.
Operators mix these up all the time, and it leads to confusion and missed opportunities.
Depletion is the amount of product that left your inventory during a specific period—whether it was sold, spilled, comped, over-poured, stolen, or wasted.
Here’s the formula:
Depletion = Starting Inventory + Purchases – Ending Inventory
It tells you what was used—not necessarily what was sold.
Now, variance is the gap between what you should have used (based on sales) and what you actually used (your depletion).
Variance = Depletion – Sales (in cost)
That gap is where your profits are leaking. Some variance is normal, but consistent or untracked variance is where your money goes missing—whether through theft, giveaways, sloppy pours, or staff not ringing things in.
And then there’s shrinkage—a general term for losses in retail or inventory-based businesses.
In bars, it usually means product that went missing due to theft, breakage, or error—but it’s less precise and more common in retail than in hospitality.
Shrinkage is kind of like saying, “Some stuff disappeared.”
It’s not a number you calculate directly. And in bar operations, it’s far more useful to talk about variance—because variance tells you what’s actually happening, and how to fix it.
You can’t see that gap without consistent tracking and accurate inventory data. And you definitely won’t catch it with a clipboard and some back-of-the-napkin math.
c. Track More Than Just COGS
COGS gets a lot of attention—and rightly so. But it’s just one piece of the puzzle.
If you’re serious about running a profitable bar, you need to track more than just what product costs. You need to understand where your money’s going, what’s working, and what’s quietly dragging your margins down.
Here’s what should be on your radar every single week:
- Weekly revenue, broken down by category (liquor, beer, wine, food)
→ So you know where the money’s actually coming from—and what’s underperforming. - Labor costs, including front-of-house, back-of-house, and management
→ Because payroll is one of your biggest expenses—and the easiest to let spiral. - Food inventory
→ With food inflation still squeezing margins, you need to track this separately. Portioning, spoilage, and waste add up fast—and hurt your bottom line in ways bar inventory doesn’t. - Liquor, beer, and wine (LBW) inventory
→ Bar inventory comes with a whole different set of risks—over-pours, comps, theft, and inconsistent counts. Variance here is almost always higher than in the kitchen, which makes weekly tracking essential if you want to spot problems early and protect your margins. - Inventory on hand—how many weeks of product you’re carrying
→ Too much stock ties up cash. Too little, and you lose sales. The sweet spot matters. - Slow movers and dead stock—items sitting on shelves with no return
→ These tie up money, space, and mental bandwidth. They need a plan—or they need to go.
Together, labor and COGS make up your prime cost—and that number is your reality check. If you’re not watching it, you’re not steering the ship.
💡 Pro tip: Keep prime cost under 60% and you’ve got room to breathe. Let it climb too high, and you’re working twice as hard for half the profit.
If you’re only checking these numbers monthly, you’re reacting. Check them weekly, and you’re leading.
d. Use the Numbers to Make Better Decisions
This isn’t about becoming a spreadsheet junkie. It’s about seeing your business clearly—so you can stop guessing and start acting on what the numbers are really telling you.
When you track the right numbers weekly, you stop reacting to problems after they’ve already hurt your margins. You start spotting them early, adjusting before they snowball, and making decisions that actually move the needle.
Here’s what that can look like:
- Adjust your par levels based on usage, not gut feelings
- Cut waste by tightening prep and portioning routines
- Negotiate better with vendors using real volume data
- Move slow stock with creative pairings or limited-time specials
- Schedule smarter to align labor with actual demand, not wishful thinking
It’s not about having perfect numbers. It’s about using the numbers you do have to make faster, smarter decisions—week after week.
Because guessing costs you money. Tracking gives it back.
3. Hire Smart and Train Smarter
A bar owner can’t run a great bar without a great team. But too many operators stop at hiring—they assume people will just “figure it out.”
They won’t. Or worse, they’ll invent their own version of what’s acceptable. That's not good bar management.
That’s why training and coaching matter.
Start by hiring for attitude. Skills can be taught. But a bad attitude? That spreads like mold in the draft lines. You want people who care—about the guest experience, about showing up for each other, and about doing things right.
Then, set expectations early and often. Don’t wait until someone “messes up” to correct them. Make it clear from day one:
- What does great service actually look like? How can your team provide memorable experiences?
- What are the non-negotiables for prep, side work, and closing?
- What’s the system for inventory—when it’s done, how it’s done, and who’s responsible?
- What are the standards for beer pours, keg rotation, and comp tracking?
- What does “clean” mean in your venue? What’s expected in terms of timing and communication?
And here’s the key: training doesn’t end after week one.
The best teams are coached, not managed. Weekly check-ins, pre-shift briefs, in-the-moment feedback, post-shift debriefs—this is what turns decent staff into rock stars.
Training isn’t just about getting people up to speed. It’s about clarity, consistency, and follow-through. And when things slip? Bar managers shouldn't ignore it - they need to address it early. They can use a simple performance improvement plan to reset expectations and give people a chance to step back up.
4. Manage Like a Leader, Not a Babysitter
Managing a bar shouldn’t feel like chasing children around. If it does, bar managers may not have a staff problem—it’s more likely you have a systems problem.
Strong systems create space. When inventory, pricing, and portion control are dialed in, managers can shift their attention from putting out fires to making better decisions. Better systems don’t just improve efficiency—they raise service standards, improve scheduling, and boost team accountability.
Start with shift structure:
- Pre-shift meetings that actually mean something (focus, updates, motivation)
- Mid-shift check-ins
- End-of-shift side work, sign-outs, and feedback loops
Use checklists. Not as micromanagement, but as accountability tools. Nobody remembers everything on a busy night. A well-designed checklist keeps everyone on the same page.
Create clear roles and responsibilities. Who’s running the floor? Who’s checking counts? Who’s approving comps or voids?
When your team knows what’s expected—and you actually follow through—everything runs smoother.
And when something goes wrong? Don’t jump straight to blame. Look at the system first. Was the expectation clear? Was the tool available? Did we train for this?
This is how a successful bar manager runs smooth operations.
You can’t improve what you don’t measure in the bar industry. Whether you audit weekly, bi-weekly, or monthly, consistency is what matters for your business operations. Inventory counting and measuring isn’t just a task—it’s a system that reveals how your business is really performing.
The average bar or restaurant loses between 20–25% of its inventory each week. That’s not a theory. It’s the competitive bar industry average. And most operators don’t even know it’s happening. Why? Because the numbers don’t get measured consistently. Or worse, they get measured—but never reviewed. You need to understand what your food costs, the beverage cost, your operating costs, your profit margin are and it can only be done with inventory management.
Outsourcing liquor inventory control, like working with Barmetrix, brings a level of precision and consistency that internal processes rarely achieve. Expert auditing identifies exactly where the money’s going—and can tell you exactly what's missing—down to the gram.
Professional audits and data analysis reveal problems that standard counts won’t catch:
- Over-pours and inconsistent pour sizes
- Guest comps that never get recorded
- Staff drinks or meals that go untracked
- Special promotions with no tracking controls
- Missed delivery errors or short orders
- Theft or careless waste
- Expired or forgotten stock collecting dust
There’s no magic number for backstock, but here’s a good benchmark: most bars should carry a retail value equal to 2.5 to 3 times their average weekly sales. That helps keep your product fresh, your cash flow healthier, and your storage under control.
Use par levels, ordering guides, and audit reports to streamline purchasing and make smarter data-driven decisions.
6. Promote Smart, Not Loud
Marketing in the restaurant business isn’t magic—it’s part of your operating system. The best bars don’t market louder. They market smarter.
Start by offering value, not discounts. Over-discounting trains guests to wait for deals. Instead, give them something memorable: exclusive tastings, themed pairings, a limited-time bar menu. These add value without undercutting your brand.
Make sure your promotions match your identity and tackle your regular customer.
A craft cocktail bar doing $1 shot nights? Not a fit. A neighborhood pub with velvet ropes? Same problem. Keep it aligned. Keep it real.
Use the tools you already have:
- In-venue touchpoints (chalkboards, menu inserts, POS displays)
- Social media presence for authenticity—not perfection
- Email and SMS for simple, consistent communication
- Take control of all your marketing channels and social media platforms for targeted promotions
- Positive experiences from regular customers lead to mouth-to-mouth marketing, so you need to understand your customer preferences.
And don’t forget: promotions are also a great way to move slow stock. Use limited-time cocktails or highlighted specials to turn dead inventory into sales.
Consistency matters more than volume. Be visible. Be on-brand. And stay top of mind.
Final Thoughts: Bars Don’t Fail from Lack of Ideas—They Fail from Lack of Planning & Execution
You already know what a great bar looks like.
But here’s the truth: bars don’t fail because the owners didn’t care. They fail because the day-to-day systems weren’t strong enough to weather the chaos of service, staffing, and supplier headaches.
Want to run a successful bar with smooth operations and have a happy staff and satisfied customers?
✔ Get your numbers tight
✔ Build a team that’s coached, not managed
✔ Focus on repeatable systems
✔ Lead with clarity
✔ Keep guests coming back for the people, not just the product
The best bars don’t run on charm. They run on consistency, accountability, and culture. That’s what keeps the doors open—and the profits rolling in.
