A warranty callback is a return visit to a customer to correct or finish work the company already performed, done at no charge because it falls under the company's workmanship guarantee or a manufacturer's warranty.
How warranty callbacks are measured
Warranty callback rate = Warranty callbacks ÷ Jobs completed in the same period × 100
Cost per warranty callback = Labor (drive + on-site) + Parts not reimbursed + Vehicle cost + Margin lost from the displaced job
Say you complete 500 jobs in a quarter and 15 come back under warranty. The rate is 3%. Each callback takes 1 hour on site and 40 minutes of drive at $45 an hour loaded ($75), $20 of vehicle cost and $30 of unreimbursed parts. That is $125 in direct cost. If the slot could have held a paying job with $150 of margin, the total is $275 each, or $4,125 for the quarter.
A manufacturer may reimburse some parts or labor on equipment warranties. Track what you recover separately so the real cost stays visible.
Why it matters
A warranty callback is a truck roll with no revenue. It also displaces paying work and often lands on a customer who is already unhappy.
It is a subset of your overall callback rate, which also includes paid return visits. Keeping warranty callbacks separate shows the cost of rework specifically. Common causes:
- Incomplete diagnosis on the first visit.
- Install or workmanship issues.
- Defective parts or equipment.
- The wrong technician for the job, which also affects first-time fix rate.
Check the service history on each callback. Patterns by technician, job type or equipment brand show where to train or change suppliers.
Scheduling matters too. Warranty callbacks are usually urgent, and they get squeezed into full days. If the slot is offered without counting the drive, the callback pushes every job after it. CrewLink computes travel from where the truck will actually be before a slot is offered, so a callback goes where a truck can actually reach it. See the dispatch board.
A common mistake
Sending whoever is free rather than the technician who did the original work, or one with the right skill. The callback is a chance to fix the problem and find the cause. A different technician starting from scratch may take longer and miss the pattern.

Common questions
What is the difference between a callback and a warranty callback?
A callback is any return visit for the same issue. A warranty callback is one you do at no charge because the original work is under guarantee.
How long should a workmanship warranty last?
It is a business decision based on your trade, competition and risk. State the term clearly at the time of sale.
Should the original technician handle the warranty callback?
Often yes, when practical. They know the job, and it gives direct feedback on what went wrong.
