What is a field service job sheet?
A field service job sheet, also called a service report or job card, is the record of one visit by a technician to a customer site. It says what was asked, who went and in which vehicle, when they arrived and left, what they found and did, which parts they used, whether the job is finished, and it carries the customer's signature.
The sheet is the basis for the invoice and for any dispute about the visit. For that reason the times on it matter: a customer who questions an arrival time or the hours charged will compare them with their own records. The visit log in this template compares them with tracking first.
How to use the job sheet and visit log
- The office opens the job: request time, customer, site, job type, priority and the response target from the contract.
- The office assigns it to a technician and vehicle with an arrival window agreed with the customer.
- The technician records each time as it happens, completes the safety check before starting and the work, parts and result at the end.
- The customer signs before the technician leaves. If they refuse or are not there, the technician writes why.
- The office checks the times against tracking and enters the visit in the Excel log.
- A second visit to the same job gets a new sheet and a new row with visit number 2, so first-time fix stays accurate.
Why compare the technician's times with tracking?
Times written at the end of the day are often rounded or estimated. A tracking system records when the vehicle entered and left the geofence drawn around the customer's site. Putting the two side by side shows three things: visits where the written time is far from the tracked time, visits that do not appear in tracking at all, and the real time spent on site, which is what you bill and plan with.
A difference is a question, not proof of a mistake. The geofence may be larger or smaller than the site, the technician may park far from the entrance, or the job may have needed a stop to collect parts. The log flags the visit and the supervisor asks.
How does the visit log calculate response time and first-time fix?
The other flags are a departure difference above the allowance, a visit with a technician arrival but no tracked arrival, a missed response target, an arrival outside the agreed window, a job not completed with no reason, and a completed job with no customer signature. The response targets of 4, 8, 24 and 72 hours by priority and the 15-minute allowance are example values on the Settings sheet; replace them with your contract terms.
Worked example: one job, two visits
Job JS-2026-303 is an emergency call-out to a mall. The request arrived at 22:40, and the response target for Emergency is 4 hours in the example.
- The technician wrote an arrival of 01:20; tracking shows the van entering the site geofence at 01:16. Response time: 01:16 − 22:40 = 2.6 hours, within the target. The 4-minute difference is inside the 15-minute allowance.
- The job needed a part, so the result was Not completed with the reason Parts needed and a follow-up visit. First-time fix: No.
- Visit 2 two days later completed the job. Tracking shows 09:38 to 11:14 on site, 96 minutes; the technician wrote 09:40 to 11:10.
- On job JS-2026-302 the technician wrote 08:30 to 11:30, but tracking shows 09:12 to 10:41. Both differences exceed 15 minutes, so the row is flagged for the supervisor.
Common mistakes with field service job sheets
- Writing times at the end of the day. Rounded times make the response and on-site figures meaningless.
- One sheet for several visits. A second visit hides inside the first, and first-time fix looks better than it is.
- "Not completed" with no reason. Without the reason you cannot tell a missing part from a closed site.
- No customer signature. An unsigned sheet is weak support for an invoice.
- Parts written as "various". Part numbers and quantities keep van stock and invoices right.
- Skipping the safety check on short jobs. Isolation and permits matter on a 20-minute job as much as on a full day.
What the template does not do
The log works with the times you copy into it; it does not read tracking data. Response targets, charges and what counts as a completed job come from your customer contracts, not from the template. Site safety rules, permits to work and isolation steps differ by customer and industry, so add the site's own requirements to section 5. For workshop repairs on your own vehicles, use the Maintenance Work Order Template instead. To size the team and the cost per visit, use the Field Service Visit Calculator.
