Segment Your Clients by Complexity, Not Assets
Good to Know
Most firms decide how much service a client receives by looking at one number: assets under management. It’s clean, it’s easy to defend, and it’s often wrong. The client who pays you the most is not necessarily the client who needs the most — and building your calendar around AUM quietly over-serves your simplest relationships while starving your most demanding ones.
The instinct is understandable. Revenue has to cover the work, so it feels natural to give the largest accounts the most attention. Kitces research shows the profession does exactly that: advisory teams averaging under $5,000 of revenue per client reported a median of 14 client touchpoints a year, while teams at $12,500 or more offered a median of 20.[1] More revenue, more service. The problem is the hidden assumption underneath — that revenue and need move together. Often they don’t.
Where the model breaks
Complexity and assets are only loosely related. A $700,000 pre-retiree in the middle of selling a business, with equity compensation, a blended family, and aging parents, is far more work — and far more exposed to a costly mistake — than a $3 million retiree with a paid-off house and a simple withdrawal plan. Tier by AUM and you hand the retiree your premium cadence and the business owner your standard one. You’ve inverted the service exactly where it matters.
It also caps your growth. Kitces’ work locates a familiar “capacity crossroads” around $250,000 to $400,000 of annual revenue per advisor — roughly 30 to 40 client relationships — beyond which service quality erodes unless something in the model changes.[1][2] Advisors who hit that wall usually respond by working longer, not by rethinking who gets what.
An advisor scenario
ADVISOR SCENARIO
A firm runs three service tiers by AUM. In the top tier sits a $2.5 million widow whose plan has barely changed in four years: quarterly meetings, a written review, priority scheduling. In the middle tier sits a couple with $700,000 who are selling a company, exercising options, blending two families, and quietly panicking about all three.
By the fee schedule, the widow is the priority. By the work — and by the risk of an expensive misstep — the couple should be getting far more of the firm’s attention. The AUM model can’t see that, so the couple gets a standard annual review and the widow gets the concierge treatment she doesn’t need.
The difference between those two outcomes isn’t compassion or competence. It’s whether the steps existed before they were needed.
A complexity-based model
The fix isn’t to abandon economics — it’s to let complexity, not just assets, drive how service is allocated. Five steps:
1
Score complexity, not just assets.
Build a short rubric: number of entities and income sources, dependents, upcoming liquidity events, tax situations, and behavioral needs. Give each client a complexity band.
2
Map service tiers to complexity bands.
Set your cadence and depth against the rubric, not the fee schedule. Some smaller relationships will earn more attention; some large, simple ones will comfortably need less.
3
Match proactive touches to what’s actually happening.
Trigger outreach off real events — a sale, a vesting date, a parent entering care — instead of a flat annual review that lands whether or not anything has changed.
4
Reprice where fee and complexity are badly mismatched.
A very complex, lower-asset client served well may be underpriced; name that honestly rather than absorbing it as invisible overservice.
5
Measure whether it worked.
Track capacity freed, retention, and whether clients say they feel understood — the metric that most predicts whether they stay.
The Bottom Line
Tiering by AUM is a proxy that has quietly stopped tracking reality. It was never really a measure of need — only of revenue — and it leaves your best work landing in the wrong places. Segmenting by complexity is how you add capacity without adding headcount, and how you make sure the clients who most need your judgment actually get it. For anyone weighing a move into the profession, it’s also a clear look at where modern advice creates its value: not in managing the most money, but in managing the most complexity well.
The firms that scale without burning out aren’t the ones with the most clients — they’re the ones who know which clients need them most.
