Pricing Power Is the Real Test of a Business

Companies describe themselves in language that is difficult to verify: differentiated, essential, trusted, category-leading. Most of it is unfalsifiable. There is, however, one test that cuts through nearly all of it, because it requires the customer to participate. Can the company raise its price and keep the customer?

Why the test works

A price increase is an involuntary survey of how substitutable something is. If customers absorb it and stay, the product occupied a position they could not easily replace. If volume falls away, the differentiation was mostly a description. Either way the answer arrives in the numbers, without anybody having to be persuaded.

Pricing power is the only competitive claim that a customer has to personally agree to.

Where it tends to come from

• —Switching costs: the time, risk or disruption involved in leaving.
• —Trust in categories where quality is hard to verify in advance.
• —Scale that lets a company hold price while absorbing cost increases.
• —Network effects, where leaving alone is worse than staying.
• —Genuine scarcity: capacity, location, licence or expertise.

How to tell whether an increase actually stuck

Announced increases and realised increases are different things. An increase that is quietly undone through promotions, extended payment terms, added scope at the same price, or a shift in mix toward cheaper products has not held — it has been relabelled. The evidence appears in gross margin over several periods and in volume alongside it.

The inverse is equally informative

A company unable to pass through rising input costs is absorbing them in margin, which is a decision with a limit. Watching how a business behaves when its costs rise is often more revealing than watching it in a favourable period, because constraint forces the real strategy into view.

This is why the test travels so well. It applies to a listed multinational and to a two-person service business, and in both cases it replaces an adjective with an observation.
