Which KPIs should a small business track?

A small business should track few indicators, and each one should lead to a decision. For almost any case, four are enough to start: cash (how much money you have available), margin (what's really left after costs), repeat customers, and one indicator of your main bottleneck. Those four tell you whether the business is breathing, whether it makes money, whether it keeps customers, and where it jams. Everything else, at the start, is noise.

The usual mistake isn't measuring too little, it's measuring too much: filling a screen with colourful charts no one looks at because none of them changes what you'll do tomorrow. A good KPI always answers the same question: if this moves, what do I do differently?

What is a KPI and how is it different from a metric?

A metric is any number you can measure. A KPI is a metric a decision depends on. That difference is everything. Visits to your website are a metric; if they rise or fall and you change nothing, it's not a KPI, it's a decorative figure. The day you decide to invest more in acquiring customers because visits are dropping, that metric becomes a KPI.

That's why there's no universal list of KPIs that fits everyone. There's a test: take any number you're measuring and ask yourself what you'd do differently if it moved. If the answer is "nothing", delete it from the dashboard. It's not informing you, it's distracting you.

Which indicators should almost any business track?

The details change by sector, but there are four that rarely go to waste:

• Cash. The money available and what's coming in and going out over the next weeks. It's the indicator that warns you before a serious problem; many profitable businesses close from running out of cash, not out of profit.
• Margin. What's left from each sale after the costs that sale drags along. Turning over a lot at a thin margin hides businesses working for others without knowing it.
• Repeat customers. What share of your sales comes from people who already bought from you. Retaining is almost always cheaper than acquiring, and this number tells you whether the business holds up or lives off chasing new customers every month.
• Your bottleneck. The indicator specific to where your business jams: lead time, occupancy, quotes that fall through, whatever slows you down. This is the one no one else can dictate to you.

With those four, you already make better decisions than with twenty charts. Add a fifth only when you actually miss something concrete, not to fill space.

How do you choose yours, step by step?

Don't copy a list off the internet. Draw them from your own decisions:

1. Write down the three decisions that worry you most. Raising prices, hiring, dropping a product, investing in acquisition. KPIs exist to feed decisions, so start with them.
2. For each decision, say what number would change your mind. That number is a KPI candidate. If no decision depends on a number, you don't need that number.
3. Check you can get the data without pain. If pulling it takes half a day a month, you won't look at it. Prefer a slightly rougher KPI that comes straight out of what you already record.
4. Set a rhythm and a threshold. How often you look and from what value you act. A KPI without a threshold is a pretty number; with a threshold, it's a useful alarm.

By the end you'll have four or five indicators tied to real decisions. That's the difference between a dashboard that gets used and one that's opened the first month and never again.

What mistakes are usually made?

Almost all of them come from confusing "having data" with "understanding the business".

When is it NOT worth building a KPI dashboard?

Measuring is useful, but it isn't always time for a dashboard:

• If you don't yet have decisions that depend on numbers. A very small, stable business sometimes runs fine from the head. First the hard decisions appear; then the KPIs that feed them.
• If you'll look at the dashboard once and forget it. A dashboard no one uses is wasted work. Better four numbers on a sheet you actually review than a gorgeous, dead dashboard.
• If the underlying data is dirty. A KPI calculated on badly recorded data lies to two decimal places. First you sort out the data; measuring comes after.

The goal isn't to have a dashboard, it's to make better decisions. If four numbers on a sheet achieve that, you don't need anything more.

Frequently asked questions

Which KPIs should a small business track?

Few, and each leading to a decision. For almost any small business, four usually do: cash (money available), margin (what's left after costs), repeat customers, and one indicator of your main bottleneck. More than five or six and you stop looking at them.

What's the difference between a metric and a KPI?

A metric is any number you can measure; a KPI is a metric a decision depends on. Visits to your website are a metric; if you change nothing whether they rise or fall, it's not a KPI. A KPI always answers the question: if this moves, what do I do differently?

How often should you look at KPIs?

It depends on the indicator: cash, weekly; margin and repeat customers, monthly. What matters isn't looking often, but looking at a fixed rhythm and acting when the number calls for it. A KPI only checked at year-end is no use for correcting in time.

Do I need expensive software to track my KPIs?

Not to start. With the data you already have in your invoicing and a spreadsheet you can track four or five KPIs. A dashboard or custom program only pays off once you know what to look at and want it updated by itself, without recalculating it by hand each month.
