The service call fee is the first price most customers hear, usually from a CSR before anyone sees the equipment. It has two jobs that pull against each other: cover the cost of visits that don't sell, and not scare off the caller who would have bought.
Service call fee in plain English
A homeowner calls because the water heater is making a banging noise. The CSR books the visit and says: "There's an $89 diagnostic fee for the plumber to come out and find the problem. If you go ahead with the repair, it's applied to the price." The plumber finds sediment, quotes a flush, and the customer approves. The $89 is credited. If the customer had declined, they'd pay $89 and the visit would still be paid for.
What does a service call fee cover?
- Drive time. Paid at the tech's full wage whether or not the customer buys.
- Vehicle cost. Fuel, wear, insurance and the truck payment, spread per trip.
- Diagnosis. The skill to find the problem, which is the part customers most underrate.
- Office time. Booking, dispatching and confirming the visit.
How do you work out your service call fee?
Break-even service call fee
"Loaded" means wages plus payroll taxes, benefits, insurance and paid time off. The figures below are examples; plug in your own, or get the loaded hourly cost from the labor rate calculator.
| Input (example) | Value |
|---|---|
| Drive time per visit | 0.6 hours |
| Diagnosis time | 0.5 hours |
| Loaded hourly cost of a tech | $95 |
| Vehicle cost per trip | $18 |
| Break-even fee | (1.1 × $95) + $18 ≈ $123 |
That is the cost of a visit that sells nothing, before any overhead or profit. A fee below it means every no-sale visit loses money, which is fine as a deliberate choice if you know your close rate and average ticket cover it.
Credit, waive or keep?
| How it works | Watch out for | |
|---|---|---|
| Keep it | Fee charged on every visit, repair priced separately | Customers may feel double-charged |
| Credit to repair | Fee applied to the repair if approved | Repair prices must carry the diagnosis cost |
| Waive for members | Members pay no fee or a reduced fee | Count waived fees as a membership cost |
| Waive entirely | Free diagnosis, all cost in repairs | Every no-sale visit is a full loss |
Service call fee vs related charges
| Charge | What it pays for | When it applies |
|---|---|---|
| Service call or diagnostic fee | Getting a tech there and finding the problem | Every diagnostic visit |
| Trip charge | Travel, sometimes by distance zone | Often outer zones, or on top of a quote |
| After-hours or emergency fee | Nights, weekends, holidays | Outside normal hours |
| Flat-rate repair price | The repair itself | When the customer approves work |
Names vary by shop; what matters is that the CSR, the tech and the invoice use the same words.
What to tell callers about the fee
Service call fee script rules
- Say the fee before booking, not at the door
- Say what it covers: coming out and finding the problem
- Say what happens if they go ahead (credited or not)
- Mention member pricing if you have it
- Use the same words on every call and on the invoice
- Never call it 'free' if any charge can apply
How the fee is handled on the phone has a direct effect on booking rate. If booking rate drops after a fee change, listen to the calls before you change the price again.
Pricing disclosure rules to know
Rules about advertised prices are tightening. California's Honest Pricing Law (SB 478), in effect since July 1, 2024, makes it unlawful to advertise or offer a price for a consumer good or service that doesn't include all mandatory fees or charges, with exceptions such as government taxes; it doesn't cover purchases for commercial use.1 So if you advertise "$79 tune-up" to California homeowners and add a mandatory trip charge, that's a problem.
The FTC's Rule on Unfair or Deceptive Fees, effective May 12, 2025, applies only to live-event tickets and short-term lodging, so it doesn't directly cover home services.2 Other state laws and general consumer protection rules still apply. This isn't legal advice; check with counsel in your state.
How service call fees work in TradesWork
In TradesWork, a service call or diagnostic fee can be set up as a price book item, so the tech's phone and the invoice show the same name and price. Price book items have a member price mode (default, percent, explicit or none), and member prices show beside regular prices on the tech's estimates; see memberships for how plan discounts apply to invoices. Multi-location shops can override the price of an item, such as a trip charge, for one branch while keeping one central price book.
