Which KPIs to measure in an SME

“What you don’t measure you can’t improve”, but the opposite mistake is just as dangerous: measuring everything and deciding nothing. Many SMEs fill dashboards with numbers no one uses, while ignoring the few indicators that really signal whether the company is healthy. A KPI (key performance indicator) is useful only if it guides a decision. If a number doesn’t change what you will do tomorrow, it is statistics, not management.

First rule: few and clear

An SME does not need fifty indicators. Five to ten are enough, chosen because they answer concrete questions: are we making money? will we collect enough to pay everyone? are we growing sustainably? Every KPI must have an owner, a reading frequency and a reference value. An indicator no one looks at regularly is time wasted producing it.

Liquidity above all

A company can be profitable on the balance sheet and fail for lack of cash. That is why liquidity is the first group of indicators to keep an eye on:

Cash balance and 3-6 month projection: how much you have and how much you will have, considering expected collections and payments.
Days sales outstanding: how long it takes on average before customers pay. Slow receivables strangle even profitable companies.
Burn rate (for those in the investment phase): how much cash you consume each month and for how many months it lasts.

For an SME these numbers matter more than profit: profit is an accounting opinion, cash is a fact.

Profitability: are you really earning?

Turnover feeds the ego, margin pays the salaries. Look at:

Gross margin: how much is left of revenues after direct costs. It tells you whether your model has room to cover everything else.
Operating margin: how much is left after all operating costs. It is the true measure of profitability.
Revenue per customer or per project: helps you understand where you earn and where you work at a loss.

Many SMEs discover, on measuring, that a slice of customers or products erodes the margin instead of generating it.

Acquisition and customer value

If you sell continuously, two numbers tell the sustainability of growth:

Customer acquisition cost (CAC): how much you spend on average to win a new customer.
Customer lifetime value (LTV): how much that customer is worth overall before leaving.

The rule is simple: if acquiring a customer costs more than they are worth, growing worsens the accounts. The ratio between the two, together with the time to recover the cost, tells you whether you can invest in growth or whether you are financing a loss.

Retention and recurrence

Retaining a customer costs much less than acquiring a new one. Useful indicators:

Churn rate: how many customers you lose in a period.
Recurring revenue: the share of turnover that is predictable, much appreciated also by those valuing the company for an investment.
Repurchase rate: how many customers come back.

A high churn turns acquisition into a leaky bucket: the more you pour in, the more leaks out.

Operational KPIs, tailored to the sector

Beyond cash and profitability, every business has one or two operational indicators of its own: utilisation rate of hours for those selling time, inventory turnover for those selling products, quote conversion rate for those working on offers. Choose the one that, if it worsens, warns you first of a problem.

From the number to the decision

A KPI lives on comparison: with the target, with the previous period, with an alarm threshold. An isolated value says nothing. Build a simple dashboard, read at a fixed regular cadence — weekly for cash, monthly for profitability — and link every indicator to an action: what do you do if it rises above or drops below the threshold? Measuring without reacting is just accounting disguised as strategy.

In summary

Choose few KPIs, each tied to a decision.
Liquidity comes before profit: cash is a fact.
Margin, not turnover, measures whether you really earn.
Compare CAC and customer value before pushing growth.
Read the indicators regularly and link each one to an action.
