An ICP is useful only when it excludes people. A profile that describes every plausible buyer changes no decision, which is why most of them sit in a slide deck and affect nothing.
An ideal customer profile describes the kind of organisation you serve best: the size, situation and characteristics that make a customer likely to buy, stay and be worth having. It is a company-level description, and it exists to make decisions — which leads to pursue, which to decline, where to spend marketing budget.
The test of a good ICP is whether it excludes. A profile matching most of your pipeline is a description of your pipeline, not a strategy, and it will change nothing about how anybody spends their week.
The most valuable half of the exercise is the anti-profile. Writing down we do not serve businesses under ten people, or we decline work requiring on-site presence, gives salespeople permission to say no and stops the slow accumulation of customers who consume support, never expand and eventually leave. Without it, every enquiry looks worth pursuing on the day it arrives.
An ideal customer profile describes the organisation; a buyer persona describes the person inside it. Both matter and they answer different questions — the ICP decides which companies to approach, the persona decides what to say when you reach somebody there. Conflating them produces a document with a company size and a job title and a photograph, which is not usable for either purpose.
Ettex CRM holds the customer records the profile is derived from and the fields you would qualify against, with the profile document itself in Ettex Docs. The value side of the same question is customer lifetime value, and the persona layer is buyer persona.
Being direct: there is no firmographic enrichment, no scoring model and no market data. The profile comes from your own customers, which for a small business is both the only source available and the better one.
A description of the type of organisation you serve best — size, sector, situation — used to decide which prospects to pursue and which to decline.
The ICP describes the company; the persona describes the person inside it. One decides who to approach, the other what to say.
From your own best customers by profit and retention, plus your worst ones. Look for shared situation and trigger events, not just size and sector.
Because they exclude nobody. A profile that matches your whole pipeline describes it rather than directing it.
A persona assembled in a workshop is fiction with a stock photograph. One built from ten customer conversations changes how you write, price and sell — and takes about a week.
Customer acquisition cost is simple to calculate and easy to calculate flatteringly. Leaving out the salaries, counting the wrong customers, or averaging across channels all produce a number that says everything is fine.
Customer lifetime value is a projection, and projections flatter. Calculated on margin rather than revenue, over a horizon you can defend, it becomes the most useful number in the business — and the most easily abused.
