Retainer or Percentage: The Argument Every Business Owner Should Hear

On a flight to a conference, he sat next to a wealth manager who had integrated cryptocurrency into his practice. The problem: his income tracked market volatility, not advisory quality. When crypto ran, he earned more than he deserved. When it corrected, less.

Over the Atlantic, he admitted he had been thinking about moving to a flat retainer.

The case is stronger than most realise.

What the Percentage Model Actually Incentivises

The standard argument: incentive alignment. The advisor only earns if the client succeeds. Skin in the game.

This sounds coherent until you consider what it actually optimises for.

An advisor on percentage has one rational objective: the fastest extractable result — highest payment in shortest time.

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

Real strategic work involves decisions whose consequences take quarters or years to materialise. Percentage creates pressure to shortcut that timeline. And if the advisor is genuinely taking entrepreneurial risk on percentage, why not build their own company? Working on percentage takes the risk without the ownership. Commission sales in a suit.

The Fee Is the FilterInability to pay a retainer is not a cash flow problem. It is a qualification signal.

A client who will not commit to a fixed fee wants the right to exit the moment advice becomes inconvenient. They consume time, not advice.

HBR data: acquiring a new client costs 5–25x more than retaining one. An advisor on percentage continuously replaces departing clients instead of compounding relationships that stay.

Clients who pay nothing treat advice accordingly — they agree, then do nothing. Retainer clients implement faster and push back harder, because they are extracting value from what they pay.

A 5% increase in retention drives profits up 25–95%, per HBR. Retainer base: compounding. Percentage treadmill: standing still.

The Numbers

Advisory practices built on retainer revenue are valued at 3.08x gross revenue on average, per the Succession Resource Group's 2025 analysis of 176 transactions (3.3 billion in AUM).

McKinsey 2024: companies with Monthly Recurring Revenue grow 30% faster and achieve valuations up to 10x higher than project-based firms.

Schwab 2024 RIA Benchmarking Study: top-performing advisory practices grew through referrals from existing high-quality clients, not volume acquisition. Quality compounds. Volume dilutes.

A percentage-based practice is not a business. It is a job with unreliable hours.

When Percentage Makes Sense

One context: transactional work with a binary, verifiable outcome and defined timeline. A deal closes or not. A property sells or not. Defined outcome, assessable contribution.

This collapses the moment work is ongoing, relationship-based, or outcome-dependent over quarters — which describes most serious service work.

Outside genuine transactional situations, the retainer wins.
