Someone at a dinner asks your best client what you do for them. Your client is delighted with your work. They say something like "he handles all my financial stuff, he's great." The person nods and the conversation moves on.
Nothing bad happened. Nothing good happened either. A referral that could have been made was not made, because your client had nothing specific to hand over.
This is the quietest revenue leak in a trust-based practice, and it is not your client's fault.
What does the missing sentence actually cost?
Referrals travel as language. Your client is not going to pull up your website at dinner. They repeat one sentence, from memory, under social pressure, in about four seconds. Whatever they can say is your entire marketing footprint in that moment.
"He handles my financial stuff" cannot be acted on. Nobody hears it and thinks "that is what I need." Compare it to "she works with dentists who are three to five years from selling their practice." The listener either fits or does not, and if they fit they will ask a second question.
The firms with steady referral flow are usually not the friendliest. They are the ones whose clients hold a sentence that survives being repeated.
Where does the fuzzy sentence come from?
From your own materials, most of the time.
Look at your homepage. If it says you provide comprehensive planning and personalized service to individuals and families, your client has nothing to borrow. They will fall back on "he's great," because that is the only true, specific thing they have.
There is a second source, and it is more sympathetic. Experienced professionals resist narrow descriptions because they can genuinely serve a wider range of people, and a narrow sentence feels like turning work away. I understand the instinct. In practice the broad sentence does not bring in the wider range, it brings in nothing, because it gives no one a reason to start a conversation.
What does a usable sentence look like?
Three parts, no more.
Who it is for. What problem you take off their plate. What is different about how you do it.
"We do tax planning for small business owners who have outgrown their bookkeeper, and we work off a fixed annual fee instead of hourly billing." That is one sentence, a client can repeat most of it, and the listener knows within a second whether it applies to them.
Write it in the language your client would use, not the language of your profession. If a term needs a definition, it will not survive being repeated at a dinner table.
How do you find out whether yours works?
Ask three clients, in a normal conversation, how they would describe your firm to a friend. Do not coach them. Write down what they actually say.
If three people give you three different answers, the sentence is missing and they are each inventing one. If they give you roughly the same answer and it is not the one you would choose, your materials are teaching them the wrong line. Both are fixable, and the fix starts on your homepage rather than in a referral conversation.
That is also why referrals behave like a system rather than a matter of goodwill, which I wrote about in Referrals Are a System, Not a Hope, and why the first thing we look at in a build is the sentence at the top of the page, described under Considered Build.
Your clients are willing to send people to you. Most of them are waiting on the words.
If you want to see how clearly your own site states who you serve, The Second Look is free and takes about four minutes.
Isn't it my job to describe the firm, not my client's?
It is your job to write the sentence. It is your client's job to repeat it, and they can only repeat what you gave them.
What if my work genuinely varies by client?
Then name the problem rather than the deliverable. Varied work usually still shares a single before-and-after, and that is what travels in conversation.
How do I know if my sentence is working?
Ask three clients and compare their answers. Consistency means the sentence landed; three different vague answers mean the source is vague.
