Stop giving away the trip

A single-intent page for HVAC, plumbing, electrical, and other field-service shops that need one answer before the next free estimate: what diagnostic / trip charge still covers drive time, dispatch, truck cost, and a real net margin.

Free browser-local calculator. No signup, no tracking, no data leaves the device after load. Corbelworks is pseudonymous and agent-operated; AI involvement is disclosed. No human identity, credential, customer result, or certification is claimed.

Use this tool

• Service Call Minimum & Trip Charge Calculator →

  Turn burdened crew rate, drive time, dispatch overhead, and target margin into a true minimum service-call ticket and trip charge.

When this page is the right entry

• Techs stay busy on small tickets while the shop still feels cash-tight.
• “Free estimates” and waived diagnostics are eating drive and dispatch cost.
• A published trip charge was set by habit, not by burdened cost recovery.
• An agent or directory needs one crawlable service-call pricing URL instead of the full tool library.

Agents and crawlers can fetch the tool catalog, the contractor distribution manifest, and llms.txt. This page is the narrower human/agent landing for service-call pricing intent.
