The Practice Changes That Take Two Years
Part six of the 18-Month File. Revenue mix, client concentration and the operational spine of a practice are the things that most change what it is worth, and none of them can be changed quickly. At six months out they are facts you inherit. At twenty-four they are still decisions.

The short answer: The structural properties of a practice, meaning its revenue mix, its concentration and whether it is documented, are what most determine its value and how well it survives any change. All three move slowly. That is the argument for starting two years out rather than six months out.
This is part six of the 18-Month File.
The previous piece dealt with who follows you. This one deals with what you are carrying.
The distinction matters because they respond to different work. Portability is about relationships. This is about the shape of the business, and it is the part that determines what the practice is worth to anyone, including to you.
Revenue mix, which is the big one
Recurring advisory fee revenue and transactional revenue are not valued alike by anyone. Recurring revenue can be underwritten, because it is reasonably expected to repeat. Transactional revenue is discounted sharply, because nobody can model it forward with confidence.
That single distinction moves valuation more than almost anything else, and the effect is laid out in what is your book actually worth.
It is also the slowest thing on this list to change, because it happens one household at a time and each conversation is a real advice conversation about how a client is served and charged, not an administrative exercise. Done properly it takes years. Done quickly it is the sort of thing that draws attention from compliance and from clients, neither of which you want.
An advisor two years out can meaningfully change their mix. An advisor six months out is taking whatever they have to market.
Concentration, which nobody volunteers
Ask an advisor what share of revenue sits in their top ten households and you get one of two responses: a precise answer, which is rare, or a pause.
The pause is the finding.
Concentration is a risk property, and it is priced by every counterparty who looks at a practice. If a third of revenue sits in ten relationships, two ordinary departures, for reasons that have nothing to do with you, become a material event. That is true in a sale, true in a transition and true if you stay exactly where you are for twenty more years.
Reducing it is slow and unglamorous: growing the middle of the book, adding relationships, and in some cases deliberately investing time in households that are not currently the loudest. There is no fast version.
Documentation, which sounds like nothing
The service model, the client segmentation, the meeting cadence, the workflows, who does what and when. In most practices this exists entirely as one person's habits.
An undocumented practice cannot be handed to anybody. Not to a buyer, not to an internal successor, not to a service team at a destination firm during the weeks when everything is in motion. The dependency only becomes visible at the moment it becomes expensive.
This is the cheapest item in the series and the one most likely to be skipped, because it produces nothing visible in the quarter you do it.
Growth attribution, which changes what you do next
Most advisors know their assets grew. Fewer can say how much came from market appreciation, how much from existing households adding, and how much from relationships won.
Those are different businesses. A practice growing on market appreciation is riding a cycle. A practice growing organically is compounding something. The two look identical on a chart of assets and behave completely differently when conditions change, and the distinction is invisible unless somebody measures it. Part two, documenting your production before you need it, covers how to keep that record.
Size itself also moves the multiple independently, which is worth knowing before deciding how hard to push on growth. That effect is quantified in the scale premium.
Why this belongs in a preparation series at all
Because it passes the test the series is built on. Every item here makes the practice better to own and run, and would be worth doing if the question of moving never arose.
More recurring revenue means more stable income. Less concentration means less risk. A documented operating model means a practice you can staff, hand over, or step away from for two weeks. None of that is transition-specific, which is precisely why it is safe to start now without having decided anything.
Next
Part seven, what not to do while you are still there, is the boundary: the ordinary, well-intentioned mistakes that convert a clean position into a contested one.
We do this work with advisors who are years from any decision, and with plenty who never make one. If you want an outside read on your own mix, concentration and growth, request an introduction. The advisor never pays, and it is held in confidence.
