Post-service customer satisfaction is the customer's view of a completed field visit, measured with the same short question set after every service record. Staff, response time, diagnosis, repair, spare parts and the report are each asked about separately. Each answer is tied to its work order. This guide covers question topics, scale choice, timing, privacy and low scores.
Why measure post-service satisfaction separately?
Post-service satisfaction is a different measure from product satisfaction. The customer is judging the visit itself: how fast the team arrived, how well the fault was diagnosed, how the repair was done, how the staff behaved and how clear the report was. The measurement should be linked to the service record. The same customer may have worked with different engineers on different dates. If a score is not matched to a work order and a service report, it is unclear which job was judged. A good measurement keeps three things together: the question set, the rating scale and the work order each answer belongs to.
Which topics should the survey cover?
Each topic gets its own question. A single general question gives too little information to act on.
- Staff: the team's manner, courtesy and whether the fault was identified on the first visit.
- Process: response time, diagnosis time and repair time, asked separately.
- Parts and report: whether spare parts arrived on time and whether the service report was delivered to the customer.
- Complaints: how easily a concern could be raised and how quickly it was resolved.
- Overall: a general rating and a question on whether the customer would choose the team again.
Choosing a scale: 1-5, 1-10 or Likert?
Choose the scale by question type. Keep the same scale for questions of the same type, so results are read against one standard.
| Scale | Best suited for | Advantage | Point to watch |
|---|---|---|---|
| 1-5 stars | Staff and process questions | Short and easy for customers to understand | Answers can cluster around the middle score |
| 1-10 | Overall rating and likelihood to choose again | Gives finer distinctions | The end points should be explained clearly to the customer |
| Likert (strongly disagree to strongly agree) | Attitude statements | Measures the degree of agreement with a statement | Longer wording can make the survey feel heavier |
| Yes / no | Callback request, report delivery | Fastest to answer | Results can only be read as a binary outcome |
When should the survey be sent?
A survey is most meaningful once the job is closed from the customer's side. Send it on the day the service report is completed or shortly after the work order closes. Define the send trigger in your own workflow. In PureField, a completed service report can be shared as a PDF, by email, and through the service report rating portal. The customer can rate the report in that portal, so the feedback is tied to the job it describes.
How NPS and CSAT are read for service work
NPS is calculated from the 0-10 question on likelihood to recommend: the share of respondents scoring 9-10 minus the share scoring 0-6. CSAT is the share of positive answers to a satisfaction question out of all answers.
- NPS shows the long-term tendency to recommend the relationship.
- CSAT shows satisfaction with a single service job.
Reading both together is useful. With a small sample, one score can mislead, so decisions are better made after several records have accumulated.
Privacy notice and consent
A survey can contain personal data such as name, email, phone number or an answer that can be linked to a person. The privacy notice should state which data is collected, why, how long it is kept and who receives it.
- Decide in advance whether answers will be linked to a person.
- Ask only for the fields the survey needs.
- State the retention period and the deletion procedure in the notice.
For the final wording, consult your legal advisor. This guide is intended as preparation.
Handling a low score
A low score should be treated like a complaint record. Find the work order it belongs to, assign a responsible person and set a callback time.
- Callback: the responsible person contacts the customer who gave the low score.
- Closure: the action taken and the outcome shared with the customer are recorded.
- Recurrence: repeated complaints on the same device or in the same area are reviewed separately.
In the PureField panel, work order assignment and field visit tracking keep these steps on the same record.
Adapting questions by equipment type
For HVAC, medical devices and industrial machinery, a shared core question set is used, and equipment-specific questions are placed in a separate section. For medical devices, calibration and verification questions are kept apart from the core set. Keep the number of questions short. Customers should be able to answer in a few minutes, since longer surveys get fewer responses.
Turning results into improvements
When survey results are read together with service report and work order data, it is easier to see which records relate to which problem. For example, if the process score is low in one area, planning records for work orders and spare parts delivery notes for the same period can be reviewed together. The review rhythm can be weekly or monthly, depending on team capacity. Each review answers three questions: which topic dropped, which device or area was affected, and which change was tried.

Frequently asked questions
How do you measure post-service customer satisfaction?
The same short question set is asked after every service record, and each answer is tied to its work order. The topics are staff, process, parts and report, complaints and an overall rating. The scale is chosen at the start and read consistently over time.
Which topics should a service satisfaction survey include?
Staff, process (response, diagnosis and repair), parts and service report, complaints and an overall rating form a solid core. A few extra questions can be added depending on the equipment type.
Should a service survey use a 1-5 or 1-10 scale?
Staff and process questions work well on a 1-5 star or Likert scale, while the overall rating and likelihood to choose again suit a 1-10 scale. What matters most is keeping the scale fixed for each question type and reading results against one standard.
When should the survey be sent?
Send it shortly after the job closes from the customer's side. The trigger can be set as completion of the service report or closure of the work order, depending on your workflow.
What should a survey privacy notice cover for GDPR or KVKK?
The notice should state which data is collected, the purpose, the retention period and who receives it. Ask only for the fields you need and decide in advance whether answers will be linked to a person. Have your legal advisor review the final text.
How should a customer who gave a low score be contacted?
Treat the low score as a complaint record. Find the related work order, assign a responsible person and set a callback time. Record the action taken and the outcome shared with the customer.
