Service call

A service call is a single scheduled visit by a contractor's technician to a customer's location to diagnose, repair, or maintain equipment. It's the basic unit of field service work — most contractors organize their day around how many service calls they can complete.

What's typically included

A standard service call usually covers:

• Travel to the customer's location
• Initial diagnosis of the reported issue
• Minor repairs or adjustments that fit within a typical visit window (usually 60-90 minutes)
• Documentation of work performed
• Customer communication about findings and next steps

Major repairs, parts replacements, or work outside the original scope are typically quoted separately — either during the same visit or as a follow-up appointment.

How service calls are priced

Most contractors structure service-call pricing as either:

• Diagnostic fee + hourly: a flat fee (typically $79-$249) to show up and diagnose, then an hourly labor rate for repair work.
• Flat-rate by job: a published price for each common repair, regardless of how long the work takes.
• Time and materials: straight hourly billing for time on site, plus parts marked up.

Service call vs estimate vs maintenance visit

• Service call — diagnostic and minor repair, billed.
• Estimate — onsite quote for larger work, usually free or applied toward the project.
• Maintenance visit — scheduled preventive service under a maintenance agreement, usually included or pre-paid.

The line between these blurs in practice — a service call can turn into an estimate when the issue is bigger than expected, and a maintenance visit can turn into a service call if the tech finds something failing.

Tracking service calls

Field service software like CrewConductor tracks service calls from booking through invoice — capturing the customer, the tech, time on site, work performed, and parts used. The data flows into the invoice automatically and into customer history for the next visit.
