Coffee shop equipment planning: can your bar actually handle your busiest hour?

Matt Powers· Calioh CoffeeTen years operating · more than fifty locations assessedUpdated October 2026

I see people spend a lot of time figuring out which espresso machine they want and almost no time figuring out how much coffee that machine needs to make.

I get it. Buying equipment is one of the fun parts of opening a coffee shop. But if the machine can't keep up with your busiest hour, you're going to have a problem that a nicer-looking bar won't fix.

Start with how much business the shop needs to do

Before you pick a machine, you need a pretty good idea of how many transactions your shop needs every day. Not how many you'd like to do. How many you actually need to do for the business to work.

Your site feasibility work should give you two numbers: the daily transactions it takes to break even and the daily transactions you need to reach your target profit margin. And don't just test the first year. Look at the tougher years of your lease, after rent increases and other costs have had time to catch up with you.

The break-even number tells you whether you can survive. The target number tells you what the equipment has to support if you want to build a successful business.

I also wouldn't size a bar around the absolute maximum number of customers a neighborhood could theoretically support. That's not a realistic sales forecast, and it's a good way to spend money on equipment you'll never use.

Now figure out what happens during the rush

Here's where I think a lot of equipment planning goes sideways. People estimate their daily sales and assume a machine that can handle that volume is good enough.

But your customers don't show up evenly throughout the day. You can have a perfectly manageable Tuesday and still get buried on Saturday morning.

I pulled 28 days of POS data from our own café to work through this. We're a full-food coffee shop, so your numbers may look different, but the process is the same.

Three things matter:

• Drinks per transaction: 1.3. We average about 1.3 beverages per check once you account for coffee, tea, chai, blended drinks, and people ordering more than one drink.
• Percentage of daily transactions in the busiest hour: 18%. On an average day, our busiest hour represents about 18% of our transactions. A commuter-heavy shop or drive-through could be higher.
• Busy-day multiplier: 2x. We had one Saturday morning hour where we made 73 drinks, roughly twice what an average day's peak would suggest. And that wasn't even our busiest hour of the day.

Let's say your shop needs to average 180 transactions a day to hit its goal.

Here's the math:

• 180 transactions × 1.3 drinks per transaction = 234 drinks per day
• 234 × 18% in the busiest hour = about 42 drinks
• 42 × 2 for a busy Saturday = about 84 drinks in one hour

That's the number I want to know before anyone starts selling me an espresso machine.

An espresso machine's capacity isn't the same as your bar's capacity

Manufacturers love to advertise how many espressos a machine can produce per hour. That's fine, but customers aren't standing at the counter waiting for espresso shots to come out of a group head. They're waiting for finished drinks.

Someone has to grind, dose, tamp, pull the shot, steam milk, make the drink, put a lid on it, and get it into someone's hand. On traditional machines, that workflow can become your bottleneck long before the machine itself does.

For planning, here's what I use based on our measurements and operating experience:

• Dual-head super-automatic: Around 90 finished drinks per hour. One model may be rated for up to 350 espressos per hour, but we measured roughly 40 seconds to produce a finished milk drink.
• Single-head super-automatic: Around 45 drinks per hour.
• Two-group traditional machine: Around 30 drinks per hour with one barista, or 55 with two.
• Three-group traditional machine: Around 80 drinks per hour with two or three baristas. We made 73 drinks on ours during a Saturday morning hour with two baristas, and we were about at our practical limit.

These aren't universal ratings, and I'm not suggesting every barista works at the same speed. They're planning numbers. Once you're operating, measure your own bar and use your own data.

If your bar is running at 90% capacity, you already have a problem

Another thing people miss is that you can't plan to have your bar working at 100% capacity for an entire rush and expect everything to run smoothly.

At 80% utilization, a simple queueing model puts the average wait in line at roughly four times the time it takes to make a drink. At 90%, it's roughly nine times. Real coffee shops have more moving parts than that model, but the lesson is the same: as you get close to capacity, wait times can get ugly fast.

Go back to our example of 84 drinks during your busiest hour:

• One dual-head super-automatic rated at 90 finished drinks an hour: 93% utilized. Too tight.
• Two of those machines, combined capacity of 180 drinks an hour: 47% utilized. Plenty of room.
• One three-group traditional setup at 80 drinks an hour: over 100% utilized. It can't keep up.

I would much rather have this conversation before spending the money than after we've got a line of frustrated customers waiting for their lattes.

And test the setup against both your break-even sales and your target sales. A bar that works at break-even but falls apart when the shop gets busy can end up putting a ceiling on your revenue.

Now figure out what the building needs

Once the equipment layout makes sense, you've got to figure out whether the space can actually support it.

This is where your equipment schedule comes in. For every piece of equipment, list the electrical requirements, whether it's hardwired or uses a plug, water and drain connections, and its dimensions. I also want to know which specs came from the manufacturer's actual cut sheet and which are still estimates.

The things I'd make sure the electrician, plumber, and architect have are:

• The total electrical load, broken down by voltage and amperage, so the electrician can evaluate the panel.
• Hardwired connections and the required circuits, including any dedicated circuits called for by the manufacturer or applicable code.
• Water connections, filtration requirements, and anything needing hot water.
• Drains, including the ones people forget, like refrigeration condensate.
• A clear list of anything that still needs to be verified before plans are submitted.

One big warning: figure out your food program early. If your cooking equipment triggers a Type 1 hood requirement, that can completely change your build-out budget and whether the space is even practical. Ventless equipment can help, but don't assume something is exempt because the salesperson says it is. Talk to your local building and health departments.
