The short definition
A KPI is a small number of measurements selected as the ones that indicate success.
The selection is the whole point. Any measurement can be reported; a KPI is one you have committed to acting on.
What makes a good one
Tied to money. Directly or by a short chain. Enquiries lead to jobs lead to revenue. Impressions do not.
Within your influence. You can change response time. You cannot change how many people searched for your trade this month.
Measured consistently. Same definition, same method, every period. Changing the definition mid-year destroys the comparison, and it is the most common way KPIs quietly stop meaning anything.
Reviewed on a schedule. A KPI nobody looks at is a number.
Sensible KPIs for a Houston service business
Three or four from this list is plenty:
- Enquiries per month, by source
- Cost per booked job, by source
- Close rate
- Response time to new enquiries
- Average job value
- Review count and rating
- Repeat customer share
Each one, moving the wrong way, has an obvious next action. That is the test.
The counting trap
More KPIs feels more rigorous and is usually less. Fifteen tracked numbers means none is genuinely watched, and when several move in different directions there is no basis for a decision.
If everything is key, nothing is.
Leading and lagging
Lagging indicators report what happened: revenue, jobs won. Accurate, and too late to act on.
Leading indicators predict what is coming: enquiries received, quotes outstanding, response time. Less certain, and actionable while it still matters.
A useful set contains both — leading indicators to steer by, lagging ones to confirm the steering worked.
Setting targets
A KPI without a target is an observation. But set targets against your own history rather than an industry figure, because published benchmarks blend businesses with nothing in common.
A reasonable approach: measure for a quarter, then set the next quarter's target from that baseline.
Choosing yours
Pick three. Write down what each should be by the end of the quarter, and what you will do if it is not.
Frequently asked questions
How many KPIs should a small business track?
Three or four. Fifteen tracked numbers means none is genuinely watched, and when several move in different directions there is no basis for deciding anything.
What makes a good KPI?
It is tied to money by a short chain, within your influence, measured the same way every period, and reviewed on a schedule. A number nobody looks at is not a KPI.
What is the difference between leading and lagging indicators?
Lagging indicators report what happened — revenue, jobs won — accurately but too late to act on. Leading indicators like enquiries received and response time predict what is coming and can still be changed.
How do I set targets?
Against your own history, not an industry benchmark. Measure for a quarter to establish a baseline, then set the next quarter's target from it.
