The Secret to Serving Big Events, the Truth About Weddings, and Tips for Long-Term Growth

Mike Radford’s next event is 200 people. His biggest before that was under 100. Does he need a second cart and a second machine?

Justin’s answer is the most useful ten minutes we have recorded on running a coffee cart. It comes down to one number.

Drinks per hour is the whole model

“I really tend to think about all my pricing and resource needs, staff and equipment, from a drinks-per-hour, per-coffee-cart basis.”

Mike’s question is missing the piece that decides it: how long is the event?

200 guests over four hours with a steady flow is 50 drinks an hour. One cart, one machine. You’re fine.

200 guests in two hours is 100 drinks an hour. Now you have a problem, and adding a barista is not the fix most people think it is.

The bottleneck is the steam boiler, not the barista

“The true bottleneck of all single-group espresso machines that run on 120 volts, aka a standard wall outlet, is their steam boiler if you’re making hot drinks. So you could add a barista, eke out a little bit more, but then your steam boiler is going to be the limiting factor.”

That is true of a $3,000 machine and a $7,000 one. Same outlet, same physics.

If you have to serve more drinks in the same window, change what you are serving:

Ways around the boiler

• Cold brew on tap
• Pre-made or bottled cold lattes
• Hot drip coffee alongside the espresso bar

If the event is over four hours, you are probably fine as is. Under two, you definitely need one of those.

Shorter events cost more, and clients don’t expect that

Justin had run this exact math on a call the same day. 125 guests, two hours, one barista on the fence.

Option one: extend service to two and a half hours. One barista at 50 drinks an hour covers it. About $1,100.

Option two: keep the two-hour window and add a second barista. That is about $200 in extra labor, marked up to $400 or more. About $1,500.

“Anytime you trigger those thresholds and have to add an extra cart or extra staff, you’re doubling staff, doubling output, and basically the price is going to double. So it’s always better, if the client’s event can accommodate it, to extend service as opposed to add more resources.”

Daniel pointed out how counterintuitive this is for the client. They ask for a shorter event expecting a discount and get a higher quote.

The fix is to show them both. Duplicate the quote in Flashquotes, change the duration or the staff count, send both links. Let them pick.

”Not everyone is going to get a drink”

Sometimes the client says: two hours, 200 people, one cart, that’s the budget. Justin books it. He just says the quiet part out loud.

“You have to be super transparent. That’s fine, but just be aware, our maximum service capacity is going to be a hundred drinks in that two-hour window. Not everyone’s going to get a drink.”

Most event planners are fine with that. There’s juice. There’s a bar. It’s an evening event.

The question to ask is whether they care more about value or speed. Value: one cart, extend service. Speed: the second barista, no line.

Conferences are the exception. Everyone sits for a session, then 200 people hit the cart in a 15-minute break. Your output does not go up. The line just gets long. Conferences almost always need two baristas.

“Conferences are insane. The drink output is bonkers.”

Big events teach you where your operation is weak

Longer, bigger events carry higher stakes, and they find the weak links. The first time you forget a critical item in front of a 500-person conference, you will not forget it again.

Justin’s take: that’s the point. Big events teach robustness. You adapt your equipment, your packing, and your staffing so you can handle them gracefully next time.

How to turn one big event into a recurring client

Every recurring client comes from being excellent the first time. If Mike’s 200-person event could ever repeat, roll out the red carpet.

I shared a study from the restaurant world that I think transfers. Once a customer visits three times, there’s a 70% chance they become a regular. Until they’ve visited three times, there’s a 70% chance they never come back.

So engineer the first three bookings. Knock the first one out of the park. Leave them with an incentive for the second. Sweeten the third. You could build the whole sequence as a workflow in Flashquotes.

Justin’s honest caveat: a $700 to $1,500 event is a bigger ask than a slice of cheesecake, so this is harder in our industry. But the principle holds.

The cheapest version: leave a bag of your beans with the person who booked you. Every morning they make coffee at home, your brand is on the counter, and it’s not as good as when your barista made it.

If you’re doing outbound, go after offices

Kenny Peterson asked where to focus outbound effort: event planners, venues, or businesses directly.

Corporate offices. Three reasons.

Frequency. A wedding planner might do a dozen weddings a year, and half the couples don’t want coffee. An office that wants you every Friday, or even every month, is a recurring account from one sale.

Calendar. Weddings are seasonal and mostly summer weekends.

“If you’re focused on weddings, you have maybe 40 to 80 days in the year that’s prime wedding business. Whereas corporate, you’ve got 250 days per year.”

Who owns the budget. A planner or venue pitches you to their client, who is spending their own money. An office administrator is the buyer, spends company money, and can book you again without reselling you to anyone.

A 100% booking rate is a warning sign

Annie closes every commercial lead she quotes and under 5% of weddings. She asked how to get more commercial leads.

Justin and I both jumped on the same thing: 100% is too high.

“You’re too hard to find, or you’re too cheap. We’ve seen that over and over again. People with low lead volume and really high booking rates, you are too hard to find.”

The sequence to fix it:

1. Get to 40 to 60 leads a month. Ten to fifteen a week is where the trends start to show. Fix your website conversion, then invest in SEO or paid ads.
2. Then read your booking rate. If it’s still over 50%, raise prices. Every quote or every few quotes, go up 5 or 10 percent.
3. Stop when it settles around 25 to 35 percent. That’s the sweet spot. You are not trying to book every lead. You are trying to get the most revenue out of each cart.

Think of it like a rental property. You could fill it 30 nights a month at $50 a night and feel great about 100% occupancy. Or book three weekends at $1,000 each and work a fraction as hard. Hotels aim for 60 to 70 percent occupancy at a good rate, not full.

On weddings specifically: the cart is one of the last things a couple books, after venue, catering, and alcohol. And January inquiries are price checks for events they won’t lock in until spring. A low wedding booking rate in winter is normal.

The January double whammy

Justin’s theory used to be that booking percentage should hold steady regardless of season. Fewer leads, same close rate.

That is not what happens.

“During slow times of the year, lead volume and booking percentage tank at the same time. It happens in January, it happens in July, and it sucks. The busiest times of year for us, December and May, have the highest inquiry volume and the highest booking percentage.”

If it’s slow right now and everything feels broken, it’s not you. Give it a month or two.

How Goodhart finances new carts

Angelica asked about financing the jump from 10 to 40 carts. Justin is now at 61 and plans to add about 30 this year.

His default is Stripe Capital. A fixed fee, repaid automatically as a small percentage of revenue that already flows through Stripe. More expensive than a bank loan, much simpler. Small business loans and lines of credit also work.

The rule for when to buy:

“If we had multiple fully booked days with our entire fleet during the last busy season, it’s time to add a cart. I add carts after every single busy season where we have fully booked days in every single city.”

Before you buy, exhaust the cheaper option. When the fleet is booked, the first question is always: do you have flexibility on your date? If the answer is no and their intent is high, that’s the $1,000 or $2,000 you just lost. Count those, and you’ll know when.

Daniel’s math: if adding a second cart drops your daily revenue per cart from $400 to $300, you now have two carts making $300 a day instead of one making $400. That’s a win. Don’t judge the decision by your slow season. Look at how much you turned away last December.

And the bootstrapper’s move, which we hear on this podcast constantly: let the big event fund the cart. Someone asks for more than you can deliver. Say yes. Quote it high. Get paid in full before the event, buy the machine, then serve it.

Custom cups, napkins, and marshmallows

Angelica’s second question was about low-quantity, fast-turnaround branded items for activations.

Etsy. Justin orders all of Goodhart’s custom cups there. Years ago this meant eight-week lead times and 1,000-cup minimums. Now you can get cups, napkins, stir sticks, even custom marshmallows for a brand activation with low minimums and quick turnaround, with built-in store reviews.

Who to hire first

Rachel asked what roles Justin has hired and what they do. For an operator at two to five carts, the order that works:

1. An operations person, promoted from your best barista. Someone reliable who is willing to sit at a laptop. They start hybrid, still working events, then take over cart prep, warehouse stocking, logistics, and eventually staffing and hiring.
2. An admin assistant for sales support. Low-level email replies, chasing branding files, verifying details. This role grows into a full event planner.

Why split it that way:

“Sales and operations will rip you apart. Sales has different goals than operations. Your sales goals pull you away from your operations goals, and your operations goals pull you away from sales goals. And the personalities and professional skill sets tend to be different.”

My framing: you are always hiring for the lowest-leverage task left on your plate. Serving drinks first. Then operations. Then sales. What’s left for the founder is marketing, process, hiring, and culture.

Best advice for someone launching a cart

Mother Coconuts asked what Justin wishes he’d known when he started.

“Just start. The lessons you most need to know are the ones other people may not be able to teach you for your unique business climate and goals. The doer alone learns.”

My addition: listen to every episode of this podcast, from the beginning. Equipment, financing, leads, SEO, pricing. If you actually do what’s in them, a six-figure business within a year is doable.

Justin’s caveat: implementation trumps knowledge every time.

Daniel brought up The War of Art again. Pressfield’s resistance is the thing telling you to plan a little more, listen to one more episode, go to one more conference. Use it as a compass. The thing you’re avoiding most is the thing to do next.
