Only the bonus model works below $50,000 a month in profit.","The three alternatives are percentage of ad spend, percentage of revenue, and performance bonuses on top of a reduced base. Percentage of ad spend is the most common and the worst aligned, because it pays your agency more when your budget grows. Revenue share works, but realistically only above $50,000 per month in profit.\n\n## The short version\n\n- **Percentage of ad spend** rewards a bigger budget, not a better one. Avoid it.\n- **Percentage of revenue** aligns properly but is only fair to both sides at scale.\n- **Reduced base plus a bonus** is the most workable hybrid, if the bonus is tied to the right metric.\n- **Tie any bonus to cost of customer acquisition, not to revenue.** Revenue can be bought.\n- **Ask what the model does when a product should be killed.** Every structure reveals itself there.\n\n## Why sellers look for an alternative\n\nUsually one of two reasons. Either the retainer feels expensive relative to a small account, or the seller wants the agency to carry some risk.\n\nBoth are reasonable. But before switching structures, be clear about what a flat fee actually buys, which is neutrality. At Flapen the fee is $800 per month for one product up to $2,400 for five, and it does not move whether we increase your ad budget or cut it in half. When I tell a client to stop spending on a product, my revenue is unaffected. That neutrality is the thing you give up when you move to any of the alternatives below.\n\n## The three alternatives\n\n| Model | How it works | The incentive it creates |\n|---|---|---|\n| Percentage of ad spend | Agency takes a cut of your ad budget, often low double digits | Spend more. Directly opposed to efficiency |\n| Percentage of revenue | Agency takes a share of sales | Grow sales, including through unprofitable spend, unless capped |\n| Reduced base plus bonus | Lower monthly fee, bonus on a defined metric | Depends entirely on which metric you choose |\n\n### Percentage of ad spend\n\nYour goal is the lowest cost of customer acquisition you can get. Their revenue rises with the budget. There is no version of this where those two things point the same direction.\n\nIt gets worse at exactly the wrong moment. When a product is underperforming, the correct advice is often to cut spend and fix the listing. Under this model, that advice costs the agency money.\n\n### Percentage of revenue\n\nBetter aligned, because the agency only earns when you sell. Two things to watch.\n\nFirst, revenue is not profit. An agency paid on revenue can hit its number by pushing spend, if there is no efficiency floor in the agreement. Cap it with a cost of customer acquisition target, or a minimum margin, or both.\n\nSecond, it punishes foundational work. If your listing needs rebuilding before ads can perform, a revenue-share agency spends three months earning very little for work that matters. We only offer revenue share above $50,000 per month in profit, at 10 to 20 percent, precisely because below that line the volatility makes it unfair to whichever side is unlucky.\n\n### Reduced base plus bonus\n\nThe most workable hybrid, and the one to negotiate if you want the agency carrying risk. A lower fixed fee covers the operating cost, and a bonus rewards the outcome.\n\nThe entire design decision is which metric the bonus sits on:\n\n1. **Cost of customer acquisition, trending down at held volume.** The best choice. Hard to game.\n2. **Contribution margin after ad spend.** Also good. Ties the bonus to money you actually keep.\n3. **Organic share of revenue.** Excellent for a brand trying to reduce ad dependence.\n4. **Revenue.** Weak, because it can be bought with your own budget.\n5. **ACoS alone.** Weak, because ACoS improves when you stop spending.\n\n## How does amazon ads performance pricing work\n\nIn practice it is one of the three above, dressed differently. Ask two questions of any performance-priced proposal.\n\nFirst, what is the baseline, and who measured it? A bonus paid against a baseline the agency set for itself is not a performance structure.\n\nSecond, what happens in a bad month, and what happens when the right call is to reduce spend? A model that has no answer to the second question will produce bad advice eventually. This is also where ACoS targets matter. A new product needs aggressive ACoS to build velocity and ranking, and a mature product needs efficient ACoS to protect margin. If the pricing model does not accommodate two different targets at two different stages, it will fight the strategy.\n\n## What most agencies will not tell you\n\nPercentage of ad spend is popular because it is easy to sell, not because it works. It sounds like the agency has skin in the game. It does, but the skin is on the wrong side.\n\nAnd the harder truth about all three alternatives: they exist to move risk, and moving risk always costs something. Usually it costs neutrality, which is the single most valuable thing an outside operator gives you. The advice you most need to hear is the advice that reduces the agency's revenue, and every alternative below a flat fee makes that advice more expensive for them to give.\n\nIf you do move off a flat fee, put the kill criteria in the contract. Rating trend, return rate, conversion rate, and cost of customer acquisition trajectory, with a defined window. That way the honest recommendation is contractually protected rather than left to goodwill.\n\n## Related answers\n\n- [Fair Amazon agency pricing models](\u002Fblog\u002Ffair-amazon-agency-pricing-models)\n- [How to structure bonuses tied to Amazon revenue](\u002Fblog\u002Fhow-to-structure-bonuses-tied-to-amazon-revenue)\n- [What to include in an Amazon PPC agency SLA](\u002Fblog\u002Fwhat-to-include-in-an-amazon-ppc-agency-sla)\n- [How to vet Amazon PPC agencies](\u002Fblog\u002Fhow-to-vet-amazon-ppc-agencies)\n- [Hiring an Amazon agency: the complete guide](\u002Fblog\u002Fhiring-an-agency)\n\nWe publish every tier rather than quoting case by case, at [Flapen](\u002Famazon-consulting).\n\n## Keep learning\n\n- [Compare Amazon business models](\u002Fguides\u002Fbusiness-models)\n- [Value your Amazon business](\u002Ftools\u002Fbusiness-value-calculator)\n","published","working-with-agencies",[14,15,16,17],"ppc","amazon-fba","fees","organic-ranking","joel-turcotte-gaucher","\u002Fimages\u002Fblog\u002Fclusters\u002Fhiring-an-agency-03.jpg","2026-09-04T00:18:51.798+00:00",{"faq":22,"seo":39,"batch":40,"cluster":41,"cover_alt":42,"answers_prompt":43,"primary_benchmark":44},[23,27,31,35],{"id":24,"answer":25,"question":26},"alternatives-to-flat-retainer-for-amazon-ppc-faq-1","Usually because the retainer feels large against a small account, or because they want the agency carrying risk.
