How to write an Ideal Customer Profile for a UK B2B business

Pull up your customer list and rank it three ways: margin, how quickly they bought, and how little they cost to keep happy. The companies near the top of all three lists are your ideal customers. They are rarely the biggest logos. Write down what they have in common before you write anything else, because everything below is about making that pattern observable.

1. Firmographics you can actually see

Sector, size, location, ownership, age and stage. In the UK the most reliable of these come from Companies House. SIC codes tell you the declared sector, although many companies pick loosely, so use them as a first cut rather than a verdict. Filed accounts give average headcount for most companies and balance sheet totals for all of them. Incorporation date gives age. Officers and persons with significant control tell you whether it is founder-run, family-owned or part of a group.

Avoid bands you cannot observe. Small private companies do not publish turnover, so a profile that says two to five million turnover forces guesswork. Headcount bands and balance sheet size are checkable.

2. Pains, in the customer's words

List the three problems your best customers had before they bought, phrased the way they described them, not the way your product sheet does. If a haulier's customers said the cold chain creaks when volume steps up, that is the pain. Temperature-controlled logistics capacity constraints is not.

3. Triggers that make the pain urgent

For each pain, name the event that makes it acute: a new retail listing, a new depot, a key hire, a contract win, an audit, a regulation with a date. These become your timing signals later, so be specific about where each one shows up.

4. Disqualifiers

The most valuable and most skipped part. Write down the companies that look like a fit and never buy: the ones with an in-house team, the ones locked into a competitor's contract, the ones too small to have the budget, the ones in administration. Every disqualifier you write saves hours of outreach later.

A profile that fits fifty thousand UK companies is not a profile. Aim for a first version that fits a few hundred to a few thousand, depending on your deal size. You can always widen it once the narrow version is working. Founders resist this because it feels like leaving money on the table. In practice a narrow profile is the only way outreach ever gets specific enough to be answered.

Finish with three or four paragraphs a new salesperson could read and act on: who these companies are, what they are dealing with, what tips them into buying and who to leave alone. Keep it in plain English. The narrative is what makes the profile usable by a person, and what makes it usable by an AI assistant when you start automating.

Stage one of Sales Architect Studio reads your website, drafts three candidate profiles with the reasoning shown, and lets you refine the one you pick by tapping cards. It writes the narrative and carries the profile into the signal, data and approach stages so the whole plan stays consistent.
