What a lean family office costs, and how to keep it lean
Built on Chapter 18 of The Single Family Office by Richard C. Wilson. Full chapter text: FamilyOffices.com.
Families choose a lean, mostly outsourced family office for many reasons, but cost is usually near the top. The pitch is simple: get the control of your own office without paying for a full staff. Whether that promise holds depends on how well the family chooses and manages its outside partners.
Where the money goes
A lean office still has costs. They tend to fall into a few buckets.
The core team. Often one or two people. In many lean offices, these are family members who work for little or no salary, which keeps fixed costs very low.
Outsourced investment help. Many lean offices hire an outsourced CIO, or hand liquid assets to a multi-family office. These fees are often tied to assets.
Accounting and reporting. Bookkeeping, consolidated reporting, and tax returns are usually handled by outside firms.
Legal and estate work. Trust and estate planning, entity setup, and deal contracts are billed by the project or the hour.
Insurance and lifestyle services. These vary widely with how the family lives.
Why lean can cost less
A smaller family rarely needs a full-time portfolio manager, estate attorney, or tax specialist. Paying for those skills only when needed keeps monthly overhead down while still meeting the family's goals.
Lean offices also avoid many fixed costs that come with a traditional office: rent for a large space, benefits for a big staff, and expensive systems built for a larger team.
Why lean can cost more than expected
Outsourcing is not free. Fees based on assets can add up as the portfolio grows. Hourly legal and tax work can balloon in a busy year. And when many providers each do a slice, someone has to coordinate them. If no one does, mistakes creep in.
The biggest hidden cost is a bad provider. Because a lean office depends so much on outside firms, choosing the wrong one does more damage than it would in a fully staffed office.
Judge cost against value
One founder I spoke with was willing to spend a modest, steady share of net assets each year on running a small office, as long as results beat the alternatives. He did not judge only on returns. He also counted family harmony, better communication, and services the family would otherwise lack.
That is the right frame. The question is not just "what does this cost?" It is "what do we get for it, compared with what else we could do?"
How to keep it lean
- Write a clear mission first, so you only buy services you need.
- Get several quotes for major services and review them every few years.
- Ask providers to agree to fee caps on routine work.
- Name one person, family member or staff, to coordinate all providers.
- Track total cost in one place and review it with the family yearly.
Resist the sales pitch
A new family office attracts a steady stream of vendors selling essential services. Many are paid on commission. In the early years, hold off on expensive research subscriptions, showy offices, and nice-to-have extras. Most well-run families find providers by referral from peers.
When lean stops making sense
As wealth and complexity grow, outsourced fees may start to exceed the cost of hiring in house. When the family is paying outside firms for full-time-level work in one area, it is time to look at hiring.
What to take from this
- Map every cost into a few clear buckets.
- Judge cost against value, including non-financial benefits.
- Name one coordinator for all outside providers.
- Revisit the in-house versus outsourced mix as wealth grows.
