What Service Fees Should a Mobile Mechanic Charge?

Here's what I've learned after 25 years of watching mobile mechanics leave money on the floor.

You're not charging enough, and you're not charging the right way.

The problem isn't your labor rate. It's that you're wrapping everything into one price like a charity bake sale. Customers can't see what they're paying for, so they haggle. You can't prove what anything costs, so you can't defend it.

Here's what actually works. Charge tangible, value-added service fees — trip fee, diagnostic fee, shop-supplies fee, after-hours fee, parts-handling fee. Things a customer can point to and say "that makes sense." Not vague junk surcharges that feel like you're just making stuff up.

The math is brutal and beautiful. These fees carry an 85–95% contribution margin because your labor and overhead are already covered by your hourly rate. Almost every dollar of fee drops straight to gross profit. That profit funds a dispatcher, a parts runner, or a second van without you selling a single extra job.

Run the numbers yourself. I'll save you the spreadsheet.

Monthly fee revenue = (attach rate %) × (monthly jobs) × ($ fee)

Fee gross profit ≈ fee revenue × 0.90

Here's a real example. A solo mobile mechanic running 120 jobs/month adds a $45 mobile-service (trip) fee at 100% attach rate — that's $5,400/mo. A $60 diagnostic fee attached on 40% of jobs — $2,880/mo. An 8% shop-supplies fee averaging $14/job at 90% attach — $1,512/mo.

Stack it up: $9,792/mo in fee revenue. Roughly $8,810/mo of gross profit. That's enough to hire a part-time office manager and still raise your average ticket by about $82/job.

The 2027 benchmark for mobile mechanics? A $39–$59 trip fee, a $49–$89 diagnostic fee, and a 6–10% shop-supplies fee capped near $25. The strongest operators run 3–4 named fees, not one inflated rate that screams "I don't know what I'm doing."

Now, the tools to actually collect these fees. I've ranked them by what they deliver for a mobile mechanic who needs to stop guessing and start billing.

1. PULSE Service Fees Calculator — Free. Instant. Answers the only question that matters: "What does this actually add to my month, and can it fund a hire?" Models that 85–95% contribution margin explicitly. Default pick for anyone deciding which fees to roll out.

2. Jobber — Most widely used field-service platform for mobile trades. Build a default "Mobile Service Fee" line item into every quote and invoice.

Set a separate diagnostic fee product. Apply percentage-based shop-supplies fee automatically. Online booking and automated quote follow-ups present fees up front.

$39/mo (Core), $119/mo (Connect), $199/mo (Grow) billed annually.

3. Housecall Pro — Best price-to-capability ratio for one-to-three-van operations. Supports custom fees, surcharge line items, built-in 2.59%–2.9% card processing.

Price-book feature saves each fee as a tappable item so techs add them in the driveway without math. $49/mo (Basic), $129/mo (Essentials), $279/mo (Max). The Essentials tier covers what most mobile mechanics need.

4. Workiz — Purpose-built for field-service dispatching. Strong on call tracking and job costing. Configure flat and percentage fees, automate a fuel/trip surcharge, tie fees to specific service types. Two-way texting and missed-call automation recover lost jobs. $45/user/mo (Lite), $95/user/mo (Standard).

5. RepairShopr (Syncro) — Excels at parts-handling fees. Tracks part cost, applies a markup rule, shows margin on every line. Cleanest way to defend a parts-handling charge to a price-sensitive customer. $59.99/mo (Basic) to $149.99/mo+.

6. ServiceTitan — Enterprise-grade. Overkill for a solo van, but growing fleets use it for dynamic pricing, fee bundling, true price book that enforces fees company-wide. Custom pricing, typically several-hundred-dollars-per-technician-per-month. For operators past 4–5 vans.

7. QuickBooks Online — Not field software, but it's where you track whether fees actually hit the bottom line. Create separate income accounts for each fee. Run a profit-and-loss that shows fee revenue distinctly from labor. $38/mo (Simple Start), $75/mo (Essentials), $115/mo (Plus).

8. Square — Simplest way for a one-person operation to collect fees on-site with a tap. Save fees as saved items in the catalog. Ring them up alongside labor. Same-day deposits. In-person processing 2.6% + 15¢, invoices 2.9% + 30¢. Free POS tier.

9. Stripe Billing — Right tool when you add recurring fleet contracts or maintenance memberships that bundle a standing service fee. Attach a monthly fleet-service fee, meter per-visit diagnostic charges, automate dunning. 0.7% on recurring invoiced volume plus standard 2.9% + 30¢ card processing.

Stop leaving $10,000 a month on the table. Your fees should fund your growth, not your excuses.
