Field Service KPIs and Metrics
If you only have time to watch a handful of numbers, watch these: close rate, average ticket, technician utilization, gross margin, and customer satisfaction. Together they tell you whether you are winning enough work, at the right price, getting it done efficiently, keeping money after costs, and leaving customers happy enough to come back. Everything else is supporting detail.
The goal of measuring is not to have a dashboard. It is to notice problems early and to know whether a change you made actually worked. A KPI (key performance indicator) earns its place only if a bad reading would make you do something different. Track fewer numbers, look at them more often, and act on them.
This guide is general education, not financial or accounting advice; benchmarks vary by trade, region, and business model.
The four categories that matter
Most field service metrics fall into four buckets. A healthy business keeps at least one KPI from each in view.
Sales
- Close rate — the share of quotes or estimates that turn into booked work. It tells you whether your pricing, follow-up, and sales conversation are working. Higher is generally better, but a rate that is too high can mean you are underpricing.
- Average ticket — average revenue per job or invoice. It reveals whether you are selling the full scope of work or leaving value on the table. Rising average ticket, without discounting quality, usually signals better estimating and upsell discipline.
Operations
- Technician utilization — the portion of paid tech hours spent on billable work versus driving, waiting, or idle. It is the single biggest lever on capacity. Higher is better, up to the point where techs are rushed.
- Jobs per day (per tech) — throughput. Useful for scheduling and capacity planning, but read it alongside average ticket so you do not reward speed over value.
- First-time-fix rate — the share of jobs resolved on the first visit. It drives both cost and customer happiness; every callback burns a truck roll you cannot bill. Higher is better.
- On-time percentage — how often techs arrive inside the promised window. It is the promise customers judge you on before any work is done. Higher is better.
Financial
- Gross margin — revenue left after the direct cost of doing the work (labor, materials, subcontractors). It tells you whether your pricing survives contact with reality. Direction matters more than any target: stable or rising is good, sliding is a warning.
- Revenue per technician — total revenue divided by field headcount. A quick read on whether each seat is productive and whether growth is real or just added cost.
- AR days (days sales outstanding) — the average time between invoicing and getting paid. Cash you have earned but not collected cannot pay wages. Lower is better.
Customer
- Customer satisfaction — a survey score or thumbs-up rate after a job. A leading indicator of retention and referrals.
- Retention / repeat rate — the share of customers who book again. Keeping a customer is far cheaper than winning a new one, so this quietly protects margin.
- Review rating — your public average across review platforms. It shapes whether strangers ever call you in the first place.
KPI quick-reference table
| KPI | What it tells you | How to improve |
|---|---|---|
| Close rate | Whether quotes convert to work | Faster follow-up, clearer estimates, financing or good-better-best options |
| Average ticket | Whether you capture full job value | Present full scope, bundle related work, train on upsell |
| Technician utilization | How much paid time is billable | Tighten scheduling, cut drive time, reduce idle gaps |
| Jobs per day | Throughput and capacity | Better routing, prep parts in advance, remove admin from techs |
| First-time-fix rate | Callbacks and wasted trips | Right parts on the truck, better diagnosis, skill matching |
| On-time percentage | Reliability customers feel | Realistic windows, live dispatch, buffer for overruns |
| Gross margin | Pricing versus real costs | Fix pricing, control material waste, track job costs |
| Revenue per technician | Productivity per seat | Raise utilization and average ticket together |
| AR days | Speed of getting paid | Invoice on-site, take payment at close, automate reminders |
| Customer satisfaction | Retention and referral risk | Close the loop on complaints, set expectations upfront |
| Retention / repeat rate | Loyalty and lifetime value | Maintenance plans, proactive outreach, consistent quality |
| Review rating | Inbound trust and lead flow | Ask happy customers to review, respond to every review |
Gross margin depends on knowing your true costs. If you are unsure what a job actually costs to deliver, start with job costing for service businesses before you trust any margin number.
How to start
You do not need all twelve. Pick three to five that map to your biggest current pain, and ignore the rest until these are under control.
- Choose one KPI per category. For example: close rate (sales), utilization (operations), gross margin (financial), and review rating (customer). Four numbers you actually look at beat twenty you never open.
- Set a baseline first. Measure where you are today before you set a goal. Without a baseline you cannot tell improvement from noise.
- Pick a review rhythm. Operations metrics suit a weekly glance; financial and customer metrics suit monthly. Put the review on the calendar so it happens whether or not the week was busy.
- Attach one action to each. A KPI with no owner and no lever is just decoration. Decide in advance who watches it and what they do when it moves the wrong way.
Common mistakes
- Tracking vanity metrics. Total jobs completed or gross revenue feel good but hide whether the work was profitable. A record month at thin margins can be worse than a quieter, healthier one.
- No baseline. Announcing a "target" close rate with no idea of the current rate means you cannot judge progress. Measure, then aim.
- Chasing one number in isolation. Push jobs-per-day without watching first-time-fix and you simply create callbacks. Push average ticket without watching close rate and you price yourself out. KPIs are read in pairs.
- Copying someone else's targets. Benchmarks vary enormously by trade, ticket size, and region. Your own trend line is a more honest coach than a number from a conference slide.
- Measuring what you cannot act on. If nobody owns the lever, drop the metric.
FAQ
How many KPIs should a small service business track? Three to five to start. Enough to cover sales, operations, financial, and customer health, few enough that you actually read them every week or month.
What is the difference between a KPI and a metric? Every KPI is a metric, but not every metric is a KPI. A KPI is a metric you have chosen because it is key — it drives a decision. The rest are context.
How often should I review my numbers? Match the rhythm to the metric. Operational numbers like utilization and on-time reward weekly attention; financial and customer numbers like margin and retention are better read monthly, where short-term noise averages out.
Next steps
Start narrow: pick one KPI from each category, record today's baseline, and put a recurring review on your calendar.
