What is a KPI (key performance indicator)?
A KPI (key performance indicator) is a measurable figure that shows how far a company has come toward a specific goal. Good KPIs are clearly defined, regularly measurable and lead to concrete decisions.

KPI: definition and distinctions
A KPI is a metric directly tied to a business goal. Not every number is a KPI: the number of website visitors is a measurement, while the number of inquiries per hundred visitors is a KPI if the goal is more inquiries. What matters is that actions can be derived from the value.
A distinction is made between strategic KPIs, such as revenue growth or customer satisfaction, and operational KPIs such as quote turnaround time, utilization or complaint rate. There are also lagging indicators, which describe a result, and leading indicators, which hint at it early, for example the number of open quotes. Good management combines both types so that deviations show up early.
How to find good KPIs
The starting point is always the goal: what should be better next year? Only then do you ask how you would recognize it. The SMART rule has proven its worth: a KPI should be specific, measurable, achievable, relevant and time-bound. It also needs a clear formula, a fixed data source and an owner.
Examples for SMEs are website conversion rate, cost per inquiry, closing rate in sales, contribution margin per order, on-time delivery, average response time in support or recurring revenue. Less is more: five to seven metrics per area can actually be monitored in day-to-day work.
- Conversion rate and cost per inquiry in marketing
- Closing rate and quote volume in sales
- On-time delivery and lead time in production
- Response time and resolution rate in support
- Contribution margin and liquidity in financial management
Real-world example: a trade business with a metrics dashboard
An electrical contractor feels constantly busy but earns little. After an analysis, four KPIs are set: quote rate (how many inquiries lead to a quote), closing rate, order margin and the time from inquiry to quote. The data comes from the job management software and time tracking. Each metric has a fixed definition and an owner who checks it weekly.
A dashboard shows the values weekly. It quickly becomes clear that quotes arrive too late on average and small jobs bring hardly any margin. The business shortens the quoting time and sets minimum prices without needing more working time for it. After a quarter, the comparison shows whether the measures work.
Common mistakes and implementation
Common mistakes are metrics without a goal, too many values, inconsistent definitions (“What counts as a lead?”) and vanity metrics such as followers or page views with no link to results. Unreliable data also devalues any dashboard. Put definitions in writing and regularly check whether a KPI still fits the goal.
Nano Concepts develops dashboards that bring together data from your website, CRM, ERP and accounting, and makes sure the values are updated automatically and presented clearly. Together with you, we first determine which figures genuinely help with decisions and which would only take up space in the dashboard.
Frequently asked questions about KPI (key performance indicator)
A metric is any measurable figure, such as revenue or number of employees. A KPI is a metric that reflects a specific goal and is used to steer decisions. So every KPI is a metric, but not every metric is a KPI.
As few as possible. Five to seven metrics per area are usually enough, and often fewer for management. Anyone who tracks too many values loses focus. What matters is that someone feels responsible and acts when there are deviations.
Vanity metrics look good but say little about business success. Examples are page views, followers or downloads with no link to inquiries or revenue. Values directly tied to results such as inquiries, orders or margin are more meaningful.
In a dashboard with a few clearly labeled values, comparison with the previous period and a traffic light or target marker. A single data source and automatic updating matter. That way, those responsible see at a glance where action is needed, without hunting through tables.
