When a Family Business Needs a Private CFO, Not a Financial Planner

The difference between managing wealth and leading through the moments that define it

March 13, 20267 min readBy Shawn McMillan, CPA.CF, ICD.D

There is a conversation I have had more than once with founders who have spent decades building a business. They have a financial planner, an accountant, an estate lawyer, and an investment manager. They are well-advised, on paper. And yet, when the moment arrives — a decision to sell, a child stepping into the business, a significant estate planning question — they find that no one is actually coordinating the full picture.

Each advisor is doing their job. The lawyer is drafting documents. The accountant is filing returns. The investment manager is managing the portfolio. But no one is sitting above the advisor layer, asking the harder question: does this all fit together? Is the plan coherent? Are we optimizing for the right things?

That is the role of a Private CFO. And it is a fundamentally different role from a financial planner.

What a Financial Planner Does — and Where It Ends

A financial planner is trained to help individuals and families manage their personal finances — savings, investments, insurance, and retirement planning. For most Canadians, a good financial planner is exactly what they need. The model works well when the financial picture is relatively straightforward: a salary, a portfolio, a mortgage, and a retirement goal.

But for a family that has built significant wealth through a privately held business, the financial picture is rarely straightforward. The business itself is often the largest asset on the family's balance sheet. The personal and corporate finances are intertwined. The tax implications of any major decision — a sale, a reorganization, a distribution — are complex and consequential. And the human dynamics of a family navigating a generational transition add a layer of complexity that no financial planning software can model.

A financial planner is not trained for this environment. That is not a criticism — it is simply a recognition that the skill set required is different. What these families need is someone who has operated inside businesses at the CFO level, who understands transactions and capital structures, who has coordinated complex advisor relationships, and who can translate all of it into clear decisions for the family.

The Moments That Require a Private CFO

In my experience working with families across Alberta and Western Canada, there are four situations where the absence of a Private CFO creates meaningful risk.

The business sale

When a family decides to sell the business they have spent a generation building, the stakes are personal as well as financial. The transaction will surface every gap in the financial reporting, the corporate structure, and the tax planning. Buyers will conduct thorough due diligence. The family's advisors — the accountant, the lawyer, the investment banker — will each be focused on their piece of the process.

What is often missing is a single point of coordination: someone who understands the full transaction, can challenge the advisors, and ensures the family's interests remain central throughout. A Private CFO fills that role. I have been through enough transactions to know that the families who navigate them best are the ones who have someone in their corner who has done it before — not just as an advisor, but as a principal. The best time to engage is at least two years prior to a sale, to ensure the business and tax optimization structures are in place well before a buyer is at the table.

The generational transition

Transitioning a business from the founding generation to the next is one of the most complex and emotionally charged events a family can navigate. The financial planning required — restructuring ownership, establishing governance, managing tax implications — is significant. But the human element is equally important: coaching the incoming generation, managing the founder's transition, and ensuring the business continues to perform through the change.

A financial planner can help with the personal financial planning aspects of a transition. A Private CFO can manage the full picture — including the parts that require operating experience and judgment that comes from having been in the chair. And more so in being a coach and advisor to the second generation taking over, so they have a trusted person they can bounce ideas off of without judgement and receive true feedback — not just a yes-person worried about their job.

Estate and wealth transfer

For first-generation wealth creators, the estate planning process often involves a corporate reorganization, a family trust structure, a holding company strategy, and a tax minimization plan that needs to be coordinated across legal, accounting, and financial advisors. The technical complexity is significant. The cost of getting it wrong — in unnecessary tax, in family conflict, in missed opportunities — is equally significant.

The challenge is that each advisor sees their piece of the puzzle. The lawyer drafts the trust documents. The accountant models the tax implications. The investment manager manages the assets. A Private CFO coordinates the whole picture, ensures the advisors are aligned, and translates the plan into language the family can understand and act on — keeping advisors in their respective lanes, as each tends to venture into providing services beyond their core role, adding noise rather than clarity for the family.

Ongoing family financial oversight

For families with significant financial complexity — multiple corporate entities, real estate holdings, investment portfolios, and operating businesses — the ongoing oversight required to manage it all well is substantial. Decisions compound over time. A distribution strategy that made sense five years ago may no longer be optimal. An investment policy that was appropriate before a liquidity event may need to be revisited.

A Private CFO provides the ongoing financial leadership that ensures the family's affairs are being managed with the same rigour and accountability that a public company board expects from its CFO. Not just compliance — strategy, grounded in someone who understands business operations from having been there before.

The Advisor Coordination Problem

One of the most consistent observations I have made working with successful families is what I call the advisor coordination problem. The family has assembled a capable team of advisors. Each advisor is technically competent. But the advisors are not coordinating with each other — and no one is coordinating them.

The result is a plan that is technically sound in each of its parts but incoherent as a whole. The estate lawyer has drafted documents that the accountant has not reviewed for tax implications. The investment manager is managing the portfolio without visibility into the corporate structure. The financial planner is projecting retirement income without accounting for the business sale proceeds.

A Private CFO sits above this layer. They do not replace the advisors — they direct them. They ensure alignment, identify gaps, hold advisors accountable for delivering on the plan, and translate complex advice into clear decisions for the family. In my experience, this coordination function alone often delivers more value than any individual advisor on the team.

What to Look for in a Private CFO

The Private CFO model is relatively new, and the term is used loosely. As with fractional CFO services generally, the quality of the practitioner varies significantly. When evaluating a Private CFO, the questions that matter most are the same ones that matter for any senior financial leader:

  • Have they operated inside businesses at the CFO level? Not as an advisor or consultant — as a principal, with accountability for outcomes. The judgment required to navigate a family through a business sale or a generational transition comes from having done it, not from having advised on it.
  • Have they led or been directly involved in transactions? M&A experience is not optional for a Private CFO working with families who are considering a sale. Ask for specifics: deal size, structure, their role, what went wrong and how they handled it. There are always learning opportunities on every deal.
  • Do they have experience coordinating complex advisor relationships? Managing a team of lawyers, accountants, and investment managers requires a specific kind of leadership — the ability to direct professionals who are often more technically specialized than you are, while maintaining a clear view of the family's overall interests.
  • Can they communicate clearly with non-financial family members? The most technically capable CFO is of limited value if they cannot translate complex financial information into language that the family can understand and act on. The ability to present the story behind the numbers — not just the numbers — is essential.

Shawn's Take

The families I have worked with most effectively are the ones who recognized, at some point, that their financial complexity had outgrown the model they were using. They had good advisors. They were not being poorly served. But they needed someone to coordinate the picture — someone who had been in the chair, who understood transactions, who could challenge the advisors when necessary, and who could help the family make clear decisions at the moments that mattered most. And more so, someone willing to have the hard conversations. Not everything is picture perfect or easy to talk about — but it still needs to be dealt with and on the table.

That is what a Private CFO does. It is not wealth management. It is financial leadership — applied to the family, with the same rigour and accountability that a well-run business expects from its CFO, to keep the risks in perspective while driving the growth.

If you are a family navigating a transition, a sale, or simply the question of how to protect and grow what you have built, I am happy to have a confidential conversation about whether this model makes sense for you.
