The main alternative is a flat fee, and it is usually the better deal. Pay-for-performance
shifts risk to the agency and pays for it with their neutrality, which matters because the
advice you most need is the advice that reduces their earnings.
The short version
- Flat fee is the primary alternative and often the better one.
- You pay for shifted risk with lost neutrality.
- Equity is a partnership, not a pricing model.
- Hybrid: flat base plus a small bonus on a hard-to-game metric.
- Ask what happens when the right advice is to spend less.
The alternatives
I run Flapen with 50 operators managing about 70 brands, on a flat fee below $50,000 a
month in profit and revenue share above it.
| Alternative | Who carries risk | What you give up |
|---|---|---|
| Flat fee | You | Nothing structural. You pay in good months and bad |
| Flat base plus small bonus | Shared | A little neutrality, in exchange for upside alignment |
| Equity partnership | Shared long-term | Control and reversibility |
| In-house hire | You | Flexibility and breadth |
| Project-based work | You, per project | Continuity |
Flat fee
The default alternative and usually the right one. Ours runs $800 a month for one product up
to $2,400 for five, with no commission and no revenue share.
The trade is honest: you pay the same whether the month was hard or easy, and some months you
get a bargain while others we do. What you buy is neutrality. When I recommend killing a
product, my revenue does not change, and that is the entire argument.
Flat base plus small bonus
The middle ground worth considering if you want some risk shared.
A standard fee covering operating cost, plus a modest bonus on a metric that cannot be gamed:
contribution margin after ad spend, or cost of customer acquisition at held volume. Keep the
bonus small enough that it does not distort the advice.
Attach a kill-criteria override so that recommending a product be stopped does not cost the
agency its upside. Without that clause, any bonus structure quietly funds keeping failures
alive.
Equity
Sometimes offered as an alternative to fees. Treat it as a corporate decision rather than a
procurement one: different governance, a much longer horizon, and a difficult exit. It can be
right, and it should never be entered as a way to avoid a monthly invoice.
The question that settles it
Ask what happens when the right advice is to spend less.
Under a flat fee, nothing. Under percentage of ad spend, the agency's income falls in
proportion. Under revenue share, it falls too. Under a bonus tied to revenue, giving the advice
costs them directly.
Every seller eventually reaches a month where the correct recommendation is to cut spend, fix
conversion, or kill a product. What your pricing structure does at that moment is the whole
question, and it is decided before any work begins.
When performance pricing fits
Two cases, and they are narrower than the marketing suggests.
Large, stable accounts above about $50,000 a month in profit, where volatility is low
enough that a bad quarter does not make the arrangement unfair to either side.
Well-defined turnarounds with an agreed baseline, a defined window, and a metric that
resists gaming. A short engagement with clear success criteria is where shared risk works
best.
Outside those, a flat fee with published pricing and month-to-month terms achieves the same
protection more directly. If the agency is not earning it, you leave in thirty days.
What most agencies will not tell you
Pay-for-performance is easiest to sell to sellers burned by a retainer that delivered little.
That reaction is understandable and it usually trades a visible problem for a subtler one.
The retainer problem is really a lock-in problem. A twelve-month contract with a ninety-day
notice window is what makes a bad retainer painful. Fix that with month-to-month terms rather
than by restructuring the economics, and you keep the neutrality while removing the trap.
The other thing: performance structures are complicated, and complexity favors whoever wrote
the agreement. Baselines, attribution windows, and metric definitions all become negotiable
after the fact in a way a flat monthly number never is.
