“Trusted advisors are not just sources of expertise. They are people clients turn to when the stakes are high, the issues are unclear, and the answer matters.”

‍

I have met recently with several services firms wanting to make the transition from being perceived as a vendor to being viewed as a trusted advisor.

Accounting firms want to be known for more than bookkeeping and compliance. Tax firms want to move beyond filings and into strategic planning.  Consulting firms want to influence enterprise decisions rather than compete on hourly rates.

There are really good reasons for this.

Vendor relationships are transactional. They often perform work the company has to do but doesn’t want to do internally. Vendors go through procurement. They provide services that several other firms can also provide. Decisions get made on responsiveness, efficiency, and price.

Advisor relationships are entirely different.

They are personal. Sticky. Hard to replace. Trusted advisors understand the client’s business deeply and help solve problems beyond the narrow scope of the original engagement. They get invited into higher-value conversations. They gain access to CEOs and boards. They influence decisions earlier. Pricing becomes less sensitive because the relationship is no longer centered on a discrete task.

The economics of this shift are significant.

Research has shown that firms generating meaningful revenue from CFO-level advisory services earned materially higher recurring revenue and faster growth than firms concentrated in traditional compliance work. See one example from CPA.com and Journal of Accountancy here: https://www.journalofaccountancy.com/news/2024/dec/growth-in-client-advisory-services-set-to-continue-rapid-increase/   Other studies on professional services firms show similar patterns: firms perceived as experts and strategic advisors grow faster, retain clients longer, and command higher fees.

Importantly, this transition is not a branding exercise.

You cannot market your way into being perceived as an advisor while still operating like a vendor internally. Clients figure that out quickly. The firms that successfully make this transition change the way they behave, organize, measure performance, develop talent, and interact with clients.

What Good Looks Like

One of the clearest signs that a firm is operating as a trusted advisor is that the client experiences the relationship differently.

The advisor is not waiting for the phone to ring. They are proactively bringing ideas. They connect the client to people. They identify risks before the client sees them. They understand the client’s broader business agenda, not just the immediate project.

The shift sounds subtle, but operationally it is massive.

Here is what the difference typically looks like:

One of the best examples of the difference came from my own experience as a client.

For years, I used a very competent accounting firm. They were responsive. Accurate. Efficient. Pricing was reasonable. I stayed with them because the work got done and switching providers felt inconvenient.

But they operated entirely like a vendor.

I never met the lead partner in person or on video. Most communication happened through forms, engagement letters, invoices, and file-sharing systems. They put effort into minimizing interaction time, which honestly is what many compliance-oriented firms are trained to do.

Eventually we switched to a provider that combined bookkeeping and tax services. There was no real emotional loss associated with leaving because there was very little relationship depth to begin with.

Ironically, this is exactly how many highly competent firms train their professionals to behave: maximize efficiency, minimize unbillable interaction, complete the task accurately, and move on. Operationally, it works. Commercially, it creates replaceability.”

How Firms Actually Make the Transition

The firms that successfully become trusted advisors usually make changes in six operating model areas.

1. Mandatory Account Planning

Most vendor firms organize around projects. Advisor firms organize around accounts and relationships.

That sounds simple, but it changes behavior dramatically.

When firms assign account ownership and require account plans, professionals begin thinking differently:

• Who are all the stakeholders?
• What are this client’s broader business priorities?
• Which relationships are weak or missing?
• What future events or risks are likely coming?
• Where can we help before an RFP exists?

The best firms also orient performance discussions around account expansion, stakeholder depth, and strategic relationship growth. Not just utilization or current project execution.

This is one reason account-based operating models are so powerful. People know exactly which clients they are responsible for developing, protecting, and expanding. They can create action plans early in the year, track progress systematically, and deepen influence with intentionality instead of randomness.

2. Broader Commercial and Industry Knowledge

In professional services, the client’s mandate is almost always broader than the advisor’s specialty.

When I worked in transfer pricing, my buyers were heads of tax at multinational companies. Transfer pricing was only one small portion of what they were responsible for.

If I stayed narrowly within my lane, I would have looked interchangeable with every other technical advisor in the market.

What changed the relationship was expanding my understanding into adjacent disciplines — particularly valuation and international tax. That broader capability allowed me to participate in much more strategic conversations, especially around intellectual property migrations and structuring decisions.

That change is important.

Clients rarely wake up thinking, “I need transfer pricing.” They think:

• “How do I reduce risk?”
• “How is this going to affect our key goals?”
• “How do I navigate this major decision?”

Trusted advisors connect their expertise to the client’s larger business outcomes.

This often requires firms to:

• Cross-train professionals
• Build broader industry knowledge
• Add adjacent service lines
• Hire people capable of strategic conversations beyond technical execution

3. Proactive Client Development

The keyword here is proactive.

Advisor relationships are built when clients feel that their advisors think about them even when no active project exists.

This is one of the hardest behavioral shifts for seller-doer firms because execution pressure is real. Most professionals are already overloaded. Waiting for inbound work feels more efficient than creating outbound relationship activity.

But firms that make the transition operationalize proactive behavior instead of leaving it to personality.

Some techniques that work include:

• Require managers to ask about BD meetings every week
• Track relationship-building activity
• Create repositories of thought leadership that can be curated and shared
• Require account plans and next-step actions
• Make it a win to bring colleagues into relationships

The last point matters more than most firms realize.

Vendor firms often unintentionally create relationship hoarding behavior. Professionals fear losing economics, control, or status if they introduce colleagues. Trusted advisor firms remove those barriers and reward collaboration because broader firm connectivity increases client stickiness.

4. Thought Leadership That Is Actually Useful

Many firms produce content. Very few produce useful thought leadership.

Trusted advisor firms build systems that reliably identify emerging client issues and translate them into practical insight.

One firm I worked with created an internal process to catalog upcoming tax rule changes affecting clients. They then built targeted deliverables and proposals tied directly to those changes. Instead of waiting for clients to ask questions, they proactively arrived with answers.

That is advisor behavior.

The goal is not mass marketing. The goal is relevance.

The most effective thought leadership is:

• Timely
• Specific
• Easy for relationship managers to curate and send
• Directly connected to a client problem or decision

Done correctly, thought leadership becomes a relationship-deepening tool, not a marketing campaign.

5. Different Pricing Structures

Pricing structure shapes client perception.

Hourly billing reinforces the idea that the client is purchasing units of labor. Retainers and value-oriented pricing reinforce the idea that the client is buying ongoing judgment, access, and strategic guidance.

That does not mean every service should move to a retainer overnight. And independence considerations may prohibit value-based pricing for some services.

But over time, advisor firms typically evolve toward:

• Retainers
• Subscription models
• Multi-phase engagements
• Roadmap-based pricing
• Outcome-oriented pricing

The strongest advisor firms are present continuously, not episodically.

6. Different Talent Expectations

Advisor firms require different skills than vendor firms.

Technical capability is still essential, but it is insufficient by itself.

Professionals need to know how to:

• Build trust
• Listen well
• Ask broader business questions
• Follow up consistently
• Facilitate executive conversations
• Connect ideas across disciplines
• Navigate ambiguity

This often requires changes in:

• Recruiting
• Training
• Promotion criteria
• Compensation
• Leadership coaching

Many firms say they want trusted advisors while still promoting almost exclusively on technical production and utilization. The organization always follows what it rewards.

This is one of the biggest reasons transformations stall.

If professionals are primarily rewarded primarily for utilization or personal books of business, they will naturally optimize around execution and relationship control. That behavior is rational. The operating model told them to do it.

Trusted advisor firms reward entirely different things:

• Expanding relationships across stakeholders
• Bringing colleagues into accounts
• Creating pull-through opportunities for the broader firm
• Proactive client development
• Long-term account growth
• Retention and strategic client penetration

In other words, they reward enterprise value creation, not just individual production.

This becomes especially important in seller-doer firms, where professionals often fear that introducing colleagues into an account will dilute economics, reduce control, or weaken their status with the client.

CEOs routinely underestimate how strongly these fears prohibit collaboration.

I have seen firms publicly encourage cross-selling while privately operating compensation systems that punish it. Professionals notice the contradiction immediately. As a result, account expansion stalls, clients experience fragmented relationships, and firms remain dependent on isolated rainmakers.

The best firms remove these barriers intentionally.

They simplify origination rules. They reward collaboration visibly. They create shared success metrics around account growth. They celebrate strategic relationship expansion, not just closed revenue. Most importantly, they ensure professionals can economically “win” by broadening client access rather than protecting territory.

What the firm rewards tells professionals what the firm actually values.

The Risks and Tradeoffs

There are tradeoffs to this transition, and CEOs should be realistic about them.

First, advisory models are harder operationally.

They require more coordination, more relationship management, and more senior attention. You cannot scale them entirely through process efficiency.

Second, not every client wants an advisor relationship.

Some clients genuinely want low-cost, efficient task execution. That is not inherently bad. In fact, highly productized vendor models can be extremely profitable when designed intentionally.

The real problem is when firms claim to be advisors while still operating transactionally.

Third, firms can overload their professionals during the transition.

Seller-doers who are already carrying heavy delivery loads often struggle to add relationship development expectations on top. Firms need to rebalance workloads, provide support systems, and coach proactively or the transformation becomes unsustainable.

Finally, advisory positioning raises the bar on talent.

Once clients perceive you as strategic, expectations rise significantly. Firms need professionals who can handle broader business dialogue, uncertainty, and executive-level interaction.

Final Thought

Moving from a vendor to a trusted advisor is one of the most valuable transformations a professional services firm can make.

Clients receive more value. Relationships become deeper and more durable. Professionals become more commercially capable. The firm becomes harder to replace. Growth becomes more repeatable. Enterprise value increases.

But the transformation only happens when the operating model changes underneath it.
