Your tech pulls into the driveway at 2:40. The job is a tripped breaker that turns out to be a bad one, or a furnace igniter, or a leaking shutoff under the sink. Forty minutes later it's fixed. The tech wants to do three things: get the paperwork signed, take payment, and get to the next job.
That's not a bad attitude. That's a good tech.
At most shops, the end of the job looks the same. The tech slaps a sticker on the panel or the furnace, and hands over a business card once the paperwork is signed. Then it's on to the next job, and that's the whole sales effort. Both just sit there: the sticker stays in the utility room, and the paper card ends up in the trash.
Your techs studied to be techs. They learned code, refrigerant charts, venting, troubleshooting. Nobody went to trade school to learn closing techniques. And yet, in the last minute of every job, they're standing in front of the one person most likely to call your shop again.
Your biggest sales team drives your trucks
Think about who actually talks to your customers. Not the office. Not the website. The person in the truck.
By our estimate, somewhere between 50 and 70% of a home service shop's staff are in trucks, depending on the business model. A shop with a big call center, sales and install crews sits near the low end. A lean service shop runs closer to the top. So a 200-person shop has roughly 100 to 140 people standing in customers' homes every day.
Your techs are your biggest sales team. They just don't want to sell. They don't have to. Show the coin. The customer scans. You're in.
And honestly, they shouldn't have to be. Customers trust the tech because the tech isn't selling. The minute it sounds like a pitch, that trust takes a hit. Most techs know that, so they skip the ask, wrap up and go.
Good work isn't enough to get the next call
Here's the hard part. Based on the data we've looked at, doing great work doesn't mean the customer calls you next time.
In a 2025 survey of 1,000 homeowners who hired an HVAC company in the past year, 94.9% said they were satisfied with their last service. But only 42.6% hired a company they had used before (FIELDBOSS, 2025, a field service software vendor). Satisfied customers still drift.
Part of the reason is simple memory. In a national survey of 863 homeowners, 45.1% couldn't name the last plumbing company they used without looking it up (Zion & Zion, 2019, plumbing customers only). Average time since their last plumber visit was more than two years. Of the people who forgot, 25% went to an internet search, and only 2% went looking for a magnet or sticker.
So your tech did the job right, the customer was happy, and two years later they search "electrician near me" or "furnace repair" and call whoever shows up first.
The best customer is the one you just made happy. One scan keeps them.
You're already paying to win that customer
You spend money on business cards, Google ads and stickers left on your work. Billet Coin lets you keep the customer you already paid for. One scan and you're in their phone.
Search ad leads for home services run roughly $90 to $130 each at the median, depending on the trade (LocaliQ, 2025). That's per lead, not per booked job. Every customer who forgets you and searches again is one you may end up paying for twice.
That sticker only works if somebody is standing in front of it. When the heat quits, the homeowner might be at work. They reach for their phone, not the basement.
Your sticker's in the utility room. They're not. Be in their phone.
Great techs and great salespeople are different people
Most owners already know this. The tech who can find a bad neutral or a cracked heat exchanger in ten minutes is rarely the person who loves asking for the sale. The personalities just don't often come in the same person.
You don't fix that by changing your people. You fix it by splitting the job.
Smart shops do two things:
- Techs flag the need. If the panel is undersized, the furnace is near the end, or the water heater is rusting out, the tech notes it and passes the lead to a comfort advisor or salesperson. The tech never has to pitch.
- They make the next call automatic. The customer should already have your shop in their phone before the truck leaves, so nobody has to remember to ask.
Great techs and great salespeople are different people. Billet Coin means your techs don't have to be both.
Take the sales out of the last minute
Your techs need one simple move that doesn't feel like selling. No script. No pitch. No asking for anything.
That's what Billet Coin is for. Each tech keeps a solid metal coin with your shop's contact info laser-marked as a QR code. Made in our shop in Fort Wayne, Indiana. At job complete, while the customer is signing on their phone or tablet, the tech holds up the coin:
"Scan this, it'll put us in your phone."
The customer points their camera at the coin and taps Add to Contacts. Your shop's contact card is saved. The tech pockets the coin and heads to the next job.
A few things worth knowing:
- The crew keeps the coin. It goes back in the tech's pocket after every scan. It's a tool, like a meter or a gauge.
- The QR saves a fixed contact card. No app, no web page, nothing to log into.
- It's the same every time. The tech doesn't have to remember what to say or decide whether the moment is right. Show, scan, saved.
Why it works for techs
Techs like it because it isn't selling. It's closer to showing the customer where the shutoff valve is.
It works the same across the trades:
- Electrical: after the panel swap or the outlet repair, the electrician shows the coin while the homeowner signs. Next time a breaker trips, your shop is in their contacts.
- HVAC: after the tune-up or the no-heat call, the tech shows the coin. When the AC quits in July, the homeowner searches their contacts, not Google.
- Plumbing: after the water heater or the drain, the plumber shows the coin. Next leak, they already have your number.
Your tech gets to be what they trained to be: the expert who fixed the problem. The coin does the part they never wanted to do.
What this means for your shop
When every truck does the same simple thing at the end of every job, keeping customers stops depending on which tech happened to be there. Your best people don't have to change who they are. Your newer people don't need a sales class.
And the customer you just made happy has you in their phone before your truck leaves the driveway.
- Get a crew quote: three styles to choose from.
- We laser-mark your shop's contact info as a QR code.
- Show your coin. They scan. You're in.
Your techs didn't sign up to sell. One scan keeps the customer anyway.
