Retainer or Percentage: What Is Better For A Strategic Partnership?

Editorial note: This article draws on the Succession Resource Group 2025 Advisory Firm Valuations Report (176 transactions, $13.3 billion in AUM), McKinsey 2024 research on B2B service firm margins and recurring revenue, Harvard Business Review data on client retention economics, the Schwab 2024 RIA Compensation and Benchmarking Study, and the IBBA Market Pulse Report 2024 on professional services valuation multiples. Analysis and first-person observations are the author's own. No advisory firms or pricing tool vendors paid for placement.

TL;DR

• Advisory practices built on recurring retainer revenue are valued at 3.08x gross revenue on average in 2025, per the Succession Resource Group's analysis of 176 transactions representing $13.3 billion in AUM. Percentage-based and project-based practices are not in the same valuation conversation.

• Companies with Monthly Recurring Revenue grow 30% faster and achieve valuations up to 10 times higher than project-based firms, per McKinsey 2024 research. The math is not ambiguous. The only question is why advisors still accept the alternative.

• The percentage-based referral model is not a pricing choice. It is a trust signal in reverse: the client who insists on it is telling you they do not believe in the value, do not intend to invest in the relationship, and want to retain the option to walk away the moment your guidance starts costing them something. The fee is not just how you get paid. It is the filter that determines who you work with.

  
  

The Conversation on the Plane

Last week I was flying to a conference. The plane was full of crypto and finance professionals heading to the same event.

I ended up seated next to a wealth manager who had recently started integrating cryptocurrency into a practice that was otherwise built on traditional asset management. He had done two things by making that move: differentiated himself in a saturated market and forced himself to confront a structural problem with his own pricing model.

The traditional wealth management model ties compensation to a percentage of assets under management or growth. On paper it sounds logical. In practice, in a market where a single day can swing a client from near-zero to thirty million dollars, it creates a fundamental problem: the advisor's income becomes a function of market volatility, not advisory quality. When the crypto market runs, he earns more than he deserves. When it corrects, he earns less. Neither number reflects what he actually contributed.

Somewhere over the Atlantic he finally admitted that he have been thinking about moving to a flat retainer model.

Over the desert I've shared that after more than a decade of experiments (anything from pro-bono to revshare models) retainer is the only model that made sense and have worked for me for years since I fully implemented it as a rule of thumb.

What follows is the complete argument for why the retainer wins every time, and why the percentage-based alternative fails not just the advisor but the client too.

What the Percentage Model Actually Incentivizes

The standard argument for percentage-based compensation is that it aligns incentives. The advisor only earns if the client succeeds. Skin in the game. Accountability through shared risk.

This argument sounds coherent until you think about what it actually optimizes for.

An advisor compensated on a percentage of outcomes has one rational objective: maximize the measurable outcome as quickly as possible. Not your long-term success. Not the strategic decisions that build durable value over three years. The fastest extractable result. Because the fastest result is the one that generates the highest percentage payment in the shortest time, which frees the advisor to move to the next client and repeat the cycle.

This is not alignment. It is misalignment with excellent marketing copy.

Real strategic advisory is, by definition, long-term. It involves decisions whose consequences take quarters or years to materialize. A percentage model cannot compensate for that timeline without creating pressure to shortcut it. The advisor who is paid on outcomes will, consciously or not, steer toward the decisions that produce the measurable outcome fastest, not the decisions that build the business most durably.

There is a deeper problem. If the advisor is genuinely taking entrepreneurial risk by working for a percentage of outcomes, then the logical question is: why is he not simply building his own company? An entrepreneur is compensated for taking risk because they own what they build. An advisor working on percentage takes the risk without the ownership. That is not entrepreneurship. That is commission sales dressed as strategic partnership. And if the work is genuinely transactional enough to be compensated that way, it does not require a strategic advisor. It requires a salesperson.

Why the Fee IS the Filter

The second argument for percentage-based models is that they lower the barrier to entry. A client with limited cash flow can engage an advisor they could not otherwise afford.

This argument has it exactly backwards.

The inability to pay a retainer is not a cash flow problem. It is a qualification signal. A founder who cannot or will not commit to a fixed advisory fee is telling you several things simultaneously: they do not believe deeply enough in the relationship to invest in it, they have not done enough due diligence to be confident in the advisor's value, and they want to retain the right to exit without cost the moment the advice becomes inconvenient.

These are not the clients who implement advice. They are the clients who consume time.

Harvard Business Review data confirms that acquiring a new client costs 5 to 25 times more than retaining an existing one. An advisor who accepts percentage-only clients is continuously replacing the clients who leave rather than compounding the value of relationships that stay. The economics are structurally negative from the first engagement.

The retainer fee solves a problem most advisors misidentify. It is not primarily an income mechanism. It is a client quality filter. The fee selects for founders who are serious enough to put money on the table before they know the outcome. Those founders, and only those founders, are the ones who actually listen to what you tell them.

I have experienced this directly. Clients who pay nothing for advice treat it accordingly. They nod in the meeting, agree with the analysis, and do nothing. The advice costs them nothing, so losing it costs them nothing. Clients who pay a retainer implement faster, follow through more completely, and push back harder when they disagree, because they are extracting value from what they are paying for. The fee does not just change how I get paid. It changes how they listen.

A 5% increase in client retention drives profits up between 25% and 95%, per Harvard Business Review research. The advisor who builds a retainer-based client base and invests in keeping those clients is compounding. The advisor who continuously accepts new percentage clients to replace the ones who left is running on a treadmill that never goes anywhere.

The Five Structural Failures of the Percentage Model

Failure 1: It mistakes activity for alignment

Percentage compensation rewards outcomes. In advisory work, many of the most important outcomes are invisible, delayed, or produced by decisions not to do something. The advisor who talks a founder out of a bad acquisition has delivered enormous value. Under a percentage model, that value produces no compensation. Under a retainer, it is part of the ongoing relationship that justifies the fee. The model that rewards outcomes systematically devalues the advisory work that prevents bad outcomes, which is often the most valuable work.

Failure 2: It makes you a product, not a partner

When a referral partner or client approaches you with a percentage arrangement, they are structuring the relationship as a transaction: bring me this outcome, I will give you this share. There is no long-term commitment on either side. No investment in building an ecosystem, a body of work, or a compounding relationship. Anyone can walk away at any point with no strings attached.

That structural impermanence produces predictable behavior. Neither party invests in depth. Neither party thinks beyond the current transaction. The result is the model that percentage defenders describe as "aligned" produces relationships that are intrinsically short-term and extractive. You deliver. They take. The arrangement dissolves when the immediate interest passes. That is not a partnership. It is a supply chain.

Failure 3: It destroys your selectivity

A professional who will work with anyone who offers a revenue share has, by definition, abandoned selectivity. Selectivity is not a luxury in advisory work. It is the mechanism by which you protect the quality of your attention, the accuracy of your advice, and the reputation that comes from working only with businesses you genuinely believe in.

The Schwab 2024 RIA Benchmarking Study found that the top-performing advisory practices grew through referrals from existing high-quality clients, not through volume client acquisition. Quality compounds. Volume dilutes. An advisor who accepts every percentage-based engagement because it costs nothing to try ends up with a calendar full of clients who will not implement advice and a reputation defined by the average of that client pool.

The retainer fee enforces a standard. It is not high enough to exclude serious founders. It is high enough to exclude the ones who are not ready to be serious.

Failure 4: It puts your integrity in the hands of people you cannot control

Here is the version of this problem that is almost never discussed: in a referral-based percentage model, you are recommending a partner or service to your own network and earning a cut of what that client pays. You are, in effect, selling your client to a third party for a percentage of their money.

What happens if that partner does not serve the client well? What if they overpromise? What if the service quality does not match what you represented? Your client did not choose this partner through independent due diligence. They chose them because you recommended them, because you had an economic incentive to recommend them.

That conflict of interest does not disappear because you believe in the partner. It is structural. And when the client eventually realizes that your recommendation was financially motivated, it is your credibility that takes the damage, not the partner's.

The retainer model eliminates this. You advise in your client's interest because your income does not depend on what they buy or who they buy it from. Your recommendation is the product. The purity of that recommendation is what justifies the retainer.

Failure 5: Fast-scaling clients abandon percentage advisors immediately

The final argument for percentage models is that they scale with client success: as the client grows, the advisor earns more. This is the theory.

The practice is different. Clients who scale quickly almost universally drop their percentage-based advisors the moment they can afford not to need them. Why? Because at the point of real scale, the client recognizes that the percentage is no longer a small number. It is a meaningful line item. And they realize they can hire multiple specialized advisors on fixed retainers for what they are currently paying one advisor on a percentage.

The percentage advisor who helped them from zero to traction gets replaced. The retainer advisors who help them from traction to scale get retained. The model that sounds like it rewards success produces advisors who are structurally excluded from the most valuable phase of client growth.

What the Retainer Model Actually Produces

The case for the retainer is not just about avoiding the failures above. It produces specific, measurable outcomes that the percentage model cannot.

• Predictable revenue that compounds. 53% of organizations now use recurring revenue models specifically because of financial stability advantages. An advisor with twelve retainer clients at a consistent monthly rate starts every month with twelve months of income already committed. That predictability is not just comfortable. It is the foundation of every other business decision: hiring, investment, capacity planning, and selective new client acceptance.

  
  

• A practice that can be valued and sold. The Succession Resource Group's 2025 analysis of 176 advisory transactions found advisory practices valued at an average of 3.08x recurring revenue, with top-quartile practices driven by high retention rates and long-term retainer contracts commanding materially higher multiples. The IBBA Market Pulse Report 2024 confirms that professional services firms with long-term retainers command top-of-range valuation multiples, while project-based and percentage-based firms sit at the bottom. A percentage-based advisory practice is not a business. It is a job with unreliable hours.

  
  

• The ability to actually advise. When your income does not depend on any specific outcome, you can recommend whatever actually serves the client. You can tell them not to do the deal. You can recommend a competitor's product. You can advise patience in a market where patience is the correct strategy. The retainer is the economic structure that makes genuinely independent advice possible. Without it, every recommendation carries the invisible weight of how it affects your next payment.

The Decision Table: What Is Better, Retainer or Percentage

There is one category where a percentage or success-fee model is genuinely appropriate. It deserves acknowledgment.

Situation	Appropriate model	Why
One-time transactional work with a binary, verifiable outcome	Success fee / percentage	Deal closes or does not. Property sells or does not. The outcome is defined, the timeline is finite, and the advisor's contribution to that specific outcome can be assessed. M&A advisory, real estate brokerage, and litigation contingency are legitimate examples.
Ongoing strategic advisory relationship	Retainer	The work is continuous, the outcomes are delayed and multi-causal, and the most valuable advice often prevents bad decisions rather than producing measurable positive ones. Percentage compensation structurally devalues this work.
Referral partnership	Disclosed referral fee, not ongoing percentage	A one-time referral acknowledgment for making an introduction is different from an ongoing revenue share that creates a continuous conflict of interest. The former is transparent and bounded. The latter is not.
Early-stage equity advisory	Equity with vesting	When the relationship is genuinely foundational and the advisor is taking a real long-term position in the company's success, equity with a proper vesting schedule is a legitimate structure. This is distinct from a percentage of revenue, which carries no long-term commitment and no skin in the actual company.

The table is short because the exceptions are narrow. Outside of genuine transactional work with binary outcomes, the retainer wins on every dimension.

Conclusion

The wealth manager on that flight understood, intuitively, that something was structurally wrong with his pricing model. He had been operating in a market, crypto, where volatility made the percentage model absurd on its face: his income spiked during bull runs and compressed during corrections regardless of whether he had done anything useful.

But the percentage model was already structurally wrong before crypto made it obvious. It was wrong in traditional wealth management. It is wrong in strategic advisory. It is wrong in any context where the work is ongoing, the outcomes are delayed, and the most valuable contribution is judgment rather than execution.

The flat retainer is not a conservative pricing choice. It is the only structure that allows the work to be done properly, the client to be served honestly, and the practice to be built into something that compounds rather than resets.

Everything else is commission sales wearing a suit.

FAQ

Q: Why does the retainer model work better than percentage-based compensation?

A: The retainer model works better for four structural reasons. First, it decouples the advisor's income from short-term outcomes, which allows advice to be genuinely strategic rather than optimized for the fastest measurable result. Second, it acts as a client quality filter: founders who commit to a retainer fee have demonstrated they value the relationship enough to invest in it before seeing returns. Third, it gives assurance and opportunity for both parties to create infrastructure around the partnership as a fundamental for the long term more effective results. Fourth, it makes the advisor's practice worth something: advisory practices built on recurring retainer revenue are valued at 3.08x gross revenue, while percentage-based practices are not in the same valuation conversation.

Q: What is wrong with percentage-based advisory models?

A: The percentage-based advisory model has five structural failures. It incentivizes short-termism rather than genuine strategic alignment. It eliminates client selectivity, flooding the advisor with unqualified engagements. It creates conflicts of interest when referral fees are involved, compromising the independence of recommendations. It produces clients who do not implement advice because free guidance carries no psychological weight. And it systematically excludes the advisor from the most valuable phase of client growth, because fast-scaling clients replace percentage advisors with retainer-based specialists the moment the percentage becomes material.

Q: Does the client who cannot afford a retainer represent an opportunity?

A: No. The inability or unwillingness to commit to a retainer fee is a qualification signal, not a cash flow problem to be accommodated. A founder who cannot commit to a fixed advisory fee is telling the advisor that they do not believe deeply enough in the value to invest in it. Harvard Business Review research documents that acquiring a new client costs 5 to 25 times more than retaining an existing one. An advisor who continuously accepts low-commitment clients to replace the ones who left is running a replacement business, not a compounding advisory practice. The fee is not just income. It is the mechanism that selects for the clients worth having.

Q: Is there any situation where a percentage model is legitimate in advisory work?

A: Yes, one: genuinely transactional work with a binary, verifiable outcome and a defined timeline. M&A advisory, where a deal closes or it does not. Real estate brokerage, where a property sells or it does not. Litigation contingency work. In these contexts, the percentage model is logical because the outcome is defined, the advisor's contribution to that specific outcome can be assessed, and the relationship ends when the transaction closes. This structure collapses the moment the work is ongoing, relationship-based, or dependent on outcomes that take quarters or years to materialize, which describes the vast majority of strategic advisory work.

Q: How does the retainer model affect business valuation?

A: Materially and consistently. The Succession Resource Group's 2025 analysis of 176 advisory transactions found practices valued at 3.08x recurring revenue, with top-quartile practices, those with high retention rates and long-term retainer contracts, commanding the highest multiples. McKinsey 2024 research found that companies with Monthly Recurring Revenue grow 30% faster and achieve valuations up to 10 times higher than project-based firms. A retainer-based advisory practice is a business with predictable cash flows, assessable client retention, and a valuation that reflects compounding relationships. A percentage-based practice is a collection of one-off transactions with no guaranteed forward revenue. These are not comparable assets.
