Bar operations: speed, stock and the last hour

At eleven on a Saturday, a cocktail bar is three deep at the counter. Each bartender walks to the far end for ice, to the middle for glasses and to the till at the other end for every order. A round of six cocktails takes nine minutes. Tabs are kept on scraps of paper behind the till, and at closing two are missing and one guest disputes theirs. The next morning, the stock count shows far more spirits gone than the till recorded, and nobody can say where they went.

Bar operations are a contest between speed and control. Guests at a busy bar want their drinks quickly, and every extra step a bartender takes is a drink not served and a guest waiting. But a bar also handles expensive stock in small measures, often late at night, and without discipline the margin leaks away in free pours, missing tabs and drinks never rung through the till.

This guide covers how to run a bar for both: the layout and the stations, a menu built for the busiest hour, the till and the tabs, pour cost and measures, bar inventory management, the team, responsible service and the last hour of the night. It is part of our venue playbooks, which start with café operations. Every venue and figure in it is an example.

A bar's trade comes in waves, often late, and the bartender's product is made in seconds from stock that is expensive, easy to over-pour and easy to give away. Guests stand as well as sit, order in rounds and often pay at the end of the night. The bartender is maker, server and cashier at once.

That shape decides what matters. Speed at the busiest hour, measures on every pour, a till that records every drink and a closing routine that accounts for every bottle are the four foundations of a bar that earns.

A bar earns most of its money in a few busy hours, and its speed in those hours decides the night. Count the drinks a bartender can make in an hour at the peak, and the drinks the bar sells in its busiest hour, and the gap is the money the bar leaves on the counter.

Speed comes from fewer steps, not faster hands: everything within reach, a short menu, drinks that can be made quickly and a till that takes an order in seconds.

Design each bartender's station so that everything for the common drinks is within one or two steps: ice, the spirits used most often, the mixers, the glasses, the garnishes and the tools. A bartender who walks to the end of the bar for ice twenty times an hour loses minutes every hour.

Give each station its own set of the essentials, rather than one shared set in the middle. Watch the bartenders during a busy hour and note every time they walk away from their station; each walk is a step to remove.

A long cocktail menu looks impressive and slows a busy bar. Each cocktail with many ingredients, a complex garnish or a long method takes time the queue does not have. A short list of drinks the bar makes well, quickly, earns more than a long one made slowly.

Design the menu with the busiest hour in mind. Batch the parts of popular cocktails that can be prepared in advance, keep the most complex drinks for quieter times and make sure every drink on the list can be made consistently by every bartender.

Preparation before service saves time during it. Juices squeezed, syrups made, garnishes cut, glasses polished and stocked, and the parts of popular cocktails batched and labelled. A bar that is fully prepared at opening can serve its first rush at full speed.

Write a preparation list for each day, based on what sold on the same day in recent weeks, and check it before service. Running out of a batched mix at midnight is as costly as running out of ice.

The bar POS should make ordering quick: the most common drinks on the first screen, a few touches for a round, and modifiers, such as a double or a different mixer, easy to add. A till that takes longer to use than the drink takes to make slows the whole bar.

Every drink must go through the till. A drink served and not recorded is stock lost without a sale, and a bar where drinks bypass the till cannot know its own margin. A drink that cannot be recorded in two touches will, on a busy night, sometimes not be recorded at all.

Bar tabs let guests order through the evening and pay once at the end. They are convenient for guests and good for sales, but they need control: each tab linked to a name and, usually, a card held or authorised, a clear record of every drink added and a check at closing that every tab is settled.

Decide the bar's rules for tabs: when one can be opened, what is needed to open it, the limit before a guest is asked to settle and what happens to a tab left open at closing. Train the team to apply them every time.

Most tab problems appear at closing: a guest who has left without paying, a tab with drinks someone else ordered, a dispute about what was served. Close tabs before the last hour gets busy, not after, and check every open tab before the bar closes.

A tab system that shows every drink, with the time it was added and who added it, makes disputes easy to settle. One kept on paper behind the till makes them impossible.

Pour cost is the cost of the drink as a share of its selling price. It is the number that tells a bar whether its prices and its pouring are right. A cocktail that costs 3.00 in ingredients and sells for 12.00 before tax has a pour cost of 25 per cent; poured with an extra few millilitres of spirit every time, its cost, and its pour cost, rise without anyone noticing.

Know the pour cost of every drink on the list, and check it when prices change. Our guide to pour cost: the number behind every drinks price covers the calculation.

Measures are the simplest control a bar has. A spirit poured with a measure costs the same every time; one poured by eye costs more, varies by bartender and makes the stock count meaningless. Free pouring may look skilful, but on a busy night it gives away the margin.

Use measures for every spirit, train the team to use them quickly and check them during service. A bartender who measures every pour serves a consistent drink and protects the bar's margin at the same time.

Bar inventory management is counting what the bar has, what it used and what it should have used, and finding the difference. The difference between the stock used and the drinks sold is the leak: over-pouring, spillage, free drinks and drinks never recorded.

Count the key stock regularly, often weekly, and compare usage with sales. Our guide to bar inventory management without closing the bar covers how to count quickly and what the variance means.

At the end of each night, a quick check of the most valuable stock, such as the open bottles of the spirits used most, catches problems the weekly count would only find later. Our guide to a bar stock checklist for the end of the night covers what to include.

The check also tells the next day's opener what to restock. A bar that closes with a clear picture of its stock opens without surprises.

Voids, comps and free drinks are part of every bar: a drink sent back, a round on the house for a regular, a mistake corrected. Each should be recorded, with a reason, so the bar can see how many there are, for whom and by whom.

Review them every week. A bartender whose comps are far above everyone else's may be generous with friends; a pattern of voids after drinks are served may hide drinks taken without payment. Most of the time, the review shows nothing wrong, and that is worth knowing too.

Late-night trade brings risks with cash and payments. Keep the cash in the till to a minimum, count it at the end of each shift with two people present where possible and record any differences.

Card and phone payments reduce the cash risk, but they need a reliable reader and a quick process. A payment that takes a minute at the busiest hour slows the bar as much as a slow drink.

A busy bar needs more than bartenders. A barback who restocks ice, glasses and bottles, clears empties and changes kegs lets the bartenders keep making drinks. On the busiest nights, one barback can be worth more than another bartender.

Staff the bar for the shape of the night: fewer at opening, the most at the peak, and enough at closing to close the tabs, clean and count. Our guide to staff scheduling against the trading curve covers how to match the rota to the night.

Train every bartender on the recipes, the measures, the till, the tab rules and the closing routine. Consistency is what makes a bar's drinks worth returning for: the same cocktail, made the same way, whoever is behind the bar.

Taste the drinks regularly and check the recipes against the menu. A bar where each bartender has their own version of the signature cocktail has no signature cocktail at all.

Bars serve alcohol, often late at night, and responsible service is both a legal duty and part of running a good bar. The team must refuse service to guests who have had too much, check ages where the law requires and know what to do when a guest becomes unwell or aggressive.

Train every member of the bar team in the rules where you trade, and support them when they refuse service. A bar where responsible service is taken seriously is safer for guests, the team and the licence.

Two things run out at the worst moment in a busy bar: clean glasses and ice. Plan both for the peak: enough glasses for the busiest hour, a glass washer that can keep up and a barback who keeps them moving; enough ice for the night, with a reserve.

A bar that runs out of a glass type at midnight serves drinks in the wrong glass or not at all. One that runs out of ice stops completely.

Many bars serve food: snacks, small plates or a full menu. Food keeps guests longer, slows their drinking and adds to the bill. But it also adds work for a bar team already busy with drinks.

Keep bar food simple and quick, prepared by a kitchen or a dedicated person where possible. A bartender who has to plate food at the busiest hour is a bartender not making drinks.

The last hour of the night decides whether the bar closes well. Call last orders clearly and at the same time each night, close the open tabs, start clearing and cleaning before the last guests leave and keep an eye on guests who have had enough.

Plan the closing routine as carefully as the opening one: the last orders, the tabs, the cash, the stock check, the cleaning and the safe departure of the team. A bar that closes in a hurry leaves problems for the morning.

Bar teams often finish very late, when public transport has stopped and the streets are quieter. Plan how the team gets home: shared taxis, a lift or a finishing time that allows the last train.

A bar that looks after its team at the end of the night keeps its team.

A few numbers tell a bar owner most of what they need: sales by hour, especially at the peak; the drinks sold per bartender per hour; the pour cost of each drink and overall; the stock variance; voids and comps by member of staff; and the staff cost against sales.

Watch them weekly. A rising stock variance, or a pour cost creeping up while prices stay the same, is a leak worth finding quickly.

Draught beer brings its own discipline. The lines must be cleaned on a schedule, the kegs changed quickly and the gas and temperature kept right, or the beer pours badly, foams and is wasted.

Train the team to change a keg quickly and correctly, and keep a spare of each popular beer ready, cold and connected where the cellar allows. A keg that runs out at the peak and takes ten minutes to change costs the bar far more than the beer.

A bar's signature drinks are what guests come back for and talk about. Keep a few, made the same way every time, priced for their ingredients and their effort, and give them a prominent place on the menu.

Cost every signature drink as carefully as the house pour, and check its pour cost when the ingredients change. A signature cocktail with a beautiful garnish that costs more than its price allows is a signature loss.

Bars are vulnerable to theft: drinks given away to friends, cash taken from the till, bottles leaving at the end of the night. Most bar teams are honest, and good controls protect them as much as the venue: every drink through the till, regular counts, voids and comps reviewed and cash counted by two people.

Treat the controls as normal practice, not as suspicion. A team that knows every bottle is counted, and that the counts are reviewed with them, rarely has anything to hide.

The mood of a bar changes through the night: a calmer early evening, a busier peak and a winding down towards close. The music, the lighting and the pace of service should follow it.

Plan the changes rather than leaving them to whoever is behind the bar. A bar whose lights come up and music changes at the same time each night signals the last hour to guests more kindly than any announcement.

An invented cocktail bar finds that its Saturday peak makes about 120 drinks an hour while the queue suggests it could sell far more. It redesigns each station so ice, the main spirits, glasses and garnishes are within reach, cuts the cocktail list from twenty to twelve, batches the parts of its four best sellers and adds a barback for the peak.

It introduces measures for every spirit, moves tabs onto the till with a name and card for each, closes tabs from half an hour before last orders and counts the key stock weekly. Within a month, peak drinks rise by about a third, tab disputes stop and the stock variance falls to a fraction of what it was.

servearound's point of sale takes orders for seated tables, so bar seats or high tables set up on the floor plan can each hold a check until it is settled, with every drink recorded, and checks can be split, merged, moved or handed to a colleague. Guests standing and ordering at a busy counter cannot be rung through servearound, and it holds no cards for tabs: payments are recorded, with cards taken on your own terminal.

Drinks can go to a bar station's own screen, an item that runs out comes off every menu at once, and voids and comps carry an optional reason, with payment analytics showing them by member of staff and sales by hour. servearound keeps no stock counts and works out no pour costs; inventory tracking is coming. See point of sale and kitchen.

Speed at the busiest hour, measures on every pour, every drink through the till and a disciplined close.

Fewer steps: stations with everything in reach, a short menu, batching and a quick till.

No. Measures keep the drinks consistent and the margin intact.

The key stock weekly, with a quick check of the most valuable items each night.

Sales by hour, pour cost, stock variance, voids and comps by member and staff cost.

Clear last orders, tabs closed early, cleaning started and the team home safely.

Bar operations balance speed and control. Design each station so everything is within reach, keep the menu short, batch what can be batched and use a bar POS that takes an order in seconds. Put every drink through the till, manage bar tabs on it with clear rules and close them before the last hour gets busy.

Know the pour cost of every drink, use measures on every pour and practise bar inventory management with weekly counts and nightly checks. Review voids and comps, staff for the shape of the night, serve responsibly and close as carefully as you open.
