Every contractor eventually has the conversation. A homeowner books a visit, you drive 25 minutes, spend half an hour finding the problem, quote the repair, and they say they’ll think about it. You’ve just given away an hour and a half and a tank of fuel. A service call fee is how you stop doing that, and how you set it, and how you explain it on the phone, matters as much as the number.
This is a guide for trade business owners: what service call fees and trip charges are, how to work out what yours should be, and how to tell customers about it without losing the booking.
Service call fee, trip charge, diagnostic fee: what’s the difference?
People use these interchangeably, and that’s part of why customers get confused. Roughly:
- Trip charge: covers getting to the job. Drive time, fuel, the truck. It doesn’t include any work.
- Diagnostic fee: covers finding the problem. Common in HVAC, appliance repair and electrical, where diagnosis takes real time and skill.
- Service call fee: usually means the trip plus a set amount of diagnosis or labor, often the first 30 minutes or so.
Pick one name, define what it covers, and use exactly the same words on your website, on the phone and on the invoice. “There’s a $X service call fee, which covers the trip and the first 30 minutes of diagnosis” is clear. “There’s a fee to come out” invites an argument later.
Should you charge a service call fee at all?
Most established trade businesses do, for good reasons. It filters out people collecting free quotes with no intention of booking. It pays you for the expertise you use to diagnose a problem, even when the customer decides to fix it themselves. And it makes your day more predictable.
The case against: some markets are competitive enough that “free estimates” wins work, especially for big-ticket jobs like roofing, remodeling or new installs, where a sales visit is part of winning a large project. Plenty of businesses charge for repair and diagnostic visits and keep estimates for installs free. That’s a sensible split.
How do you work out what to charge?
Start from your real costs, not what the shop down the road charges. A simple method:
- Work out your cost per hour on the road. Technician wages and payroll costs, plus the truck (payment, insurance, fuel, maintenance), plus a share of overhead like the office, software and phones, divided by the hours your techs actually bill.
- Estimate a typical service visit. Average drive time each way plus the diagnosis time you want covered.
- Multiply, then add your margin.
Here’s a made-up example to show the arithmetic. Use your own figures. If your loaded cost is $95 an hour and a typical visit is 30 minutes of driving plus 30 minutes of diagnosis, the visit costs you $95. With a 30 percent margin you’d land around $125. If your service area is large, consider a higher fee or a zone surcharge for the far edges rather than averaging it across everyone.
Should the fee go toward the repair?
Many contractors credit the service call fee against the repair if the customer goes ahead the same day. It’s a strong sales line: “If you go ahead with the repair today, the $125 comes off the bill.” It rewards the customers you want and still covers you for the ones who walk away. Just build it into your pricing so the credit doesn’t eat your margin on the repair.
What about nights, weekends and emergencies?
An after-hours or emergency call costs you more: overtime, an on-call tech, a ruined evening. A separate after-hours fee is normal. The important thing is that callers hear it before anyone drives out. It also filters calls: once people know a 9 p.m. visit costs more, a lot of them will happily take 8 a.m. instead. Our guide to emergency answering services covers how to route those calls.
How do you explain the fee on the phone?
Say it early, say it plainly, and say what it gets them. A script that works:
“Before I book you in, just so you know, our service call is $125. That covers the technician coming out and the first half hour finding what’s wrong. If you go ahead with the repair while he’s there, the $125 comes off the bill. Does that work for you?”
If they push back with “the other company does it free”, don’t argue. “That’s fine, a lot of companies build it into their repair prices instead. Ours is upfront so there are no surprises.” Some callers will still go elsewhere, and that’s the fee doing its filtering job.
The thing to avoid is the fee appearing for the first time on the invoice. That’s how you get bad reviews from customers you actually helped.
Where else should the fee appear?
- On your website, near your booking button.
- In the booking confirmation text or email.
- In whatever script your office, answering service or AI receptionist uses, word for word.
That last point is easy to miss. If whoever answers your phone explains the fee differently from how you do, customers get mixed messages. An AI receptionist like Ansdale, which is ours, can state your service call fee on every call exactly as you word it, including the after-hours version, before it books the visit. Plans start at $49 a month.
Questions people ask
What is a service call fee?
A fee for sending a technician to your home, usually covering the trip and a set amount of diagnosis time. Some companies credit it against the repair if you go ahead.
Is a trip charge the same as a service call fee?
Not quite. A trip charge usually covers only getting to the job, while a service call fee often includes some diagnosis or labor. Businesses use the terms differently, so define yours clearly.
How do I calculate my service call fee?
Work out your loaded cost per hour on the road, multiply by the time a typical visit takes including driving, and add your margin. Base it on your own costs rather than competitors’ prices.
When should I tell customers about the service call fee?
On the phone before booking, on your website, and in the booking confirmation. It should never appear for the first time on the invoice.
