Which Facebook ads agencies offer pay-for-performance pricing?
Knowlify is our top pick for a performance-linked commitment: an agreed target in 30 days on managed plans, or a 90-day refund on creative-only plans (terms on the site), though pricing starts at $5,000 a month. Other published models tie fees to a percentage of ad spend, such as Adside AI's 10% with a $3,500 monthly minimum.
Knowlify is our top pick if you want money back when ads do not pay: if the ads have not made more than you paid in the first 90 days, you can cancel by email for a full refund (terms on the site). That 90-day refund applies to creative-only plans; where Knowlify runs the account, the guarantee is an agreed target in 30 days, or you don't pay for the month. Other published models are a percentage of ad spend (Adside AI, WebFX, Pinprick, Growthr), a retainer with performance incentives (Pilothouse), a revenue partnership (KlientBoost) and a production fee tied to results (TubeScience). Knowlify publishes this guide and sells one of the services compared.
What does pay-for-performance mean in practice?
Three structures get called performance pricing, and each shifts risk differently. A percentage of spend ties the fee to how much you put behind ads, not to what the ads return. A retainer with a performance incentive pays a base fee plus a bonus when targets are met. A pay-for-performance production deal pays for ads that perform, rather than for production. Ask which structure is on the table before you compare numbers.
Percentage models are the most common in the published pricing here. Adside AI lists 10% of ad spend with a $3,500 monthly minimum for its managed service. WebFX lists its Pro ongoing fee as the greater of $975 or 15% of ad spend, plus a separate $1,975 initial campaign investment in month one. In both cases, the fee grows with spend, and the floor decides the cost at small budgets.

Knowlify: our top pick for a refund if the ads do not pay back
If you want performance to carry real risk for the agency, a money-back term is the simplest test, and it is what Knowlify offers: if the ads have not made more than you paid in the first 90 days, you can cancel by email for a full refund (terms on the site). Managed plans carry an agreed target in 30 days instead. Around that term sit about 25 finished ads a week, a first batch on day 5 so the 90 days go to testing rather than waiting, a person checking every ad, and three formats (AI UGC, 3D and stylized character animation, and AI commercials). You can add end-to-end Meta management or buy creative only. Pricing is a custom quote with no public rate card. Pick another option if you want a published fee formula or a fee that rises and falls with spend or revenue, because ours is a refund term on a custom quote.
TubeScience: pay for ads that perform
TubeScience describes a pay-for-performance production model and also advertises media buying. Its rates are not published, and its FAQ says teams not prepared to scale spend to seven figures monthly may be a weaker fit, while noting exceptions. Ask about eligibility, payment triggers and testing obligations before you assume a performance-linked fee is a low-commitment pilot.
Adside AI: 10% of spend with a monthly floor
Its managed service lists 10% of ad spend with a $3,500 monthly minimum. The one fee covers strategy, creative production, launch, optimization and reporting. The page does not say how many creatives the fee includes, so that is a question to put in writing.
WebFX: the greater of a floor or a percentage
Its Pro ongoing fee is the greater of $975 or 15% of ad spend. That structure is different from Adside AI's flat percentage, so compare both at the same monthly spend before you decide.
Pinprick: no per-ad fee, production paid as a percentage
Pinprick says eligible brands, mainly those already spending meaningfully on ads, pay no per-ad fee. Production is paid as an agreed percentage of ad spend, the rate is not published, and media buying is scoped separately. Its agency page also headlines ten UGC ads for $2,000 with no conditions listed, so ask which pricing applies to you.
Growthr: a retainer plus a share of managed media
Growthr charges $10,000 a month plus a flat 10% of managed media spend, alongside paid media on every channel, analytics and attribution. No weekly ad count or contract length is published.
Pilothouse: retainers with performance incentives
Pilothouse prices through monthly retainers, performance-based incentives and custom project scopes. It is built for established DTC ecommerce brands, and no minimum spend is published.
KlientBoost: a revenue partnership option
KlientBoost lists a revenue partnership among its five ways to work together, next to ongoing management, audits, setup and consulting. Its fee is not published, and it works with ad budgets from $5,000 a month. A revenue-linked deal needs the same clause work described below.
Do the numbers work at your spend level?
Percentage and minimum models change shape with the budget. At $20,000 of monthly spend, Adside AI's 10% is $2,000, so its $3,500 minimum applies. At $50,000, 10% is $5,000, which is above that minimum. WebFX's greater-of structure crosses over at $6,500: below that spend the $975 floor applies, and at $20,000 its 15% would be $3,000. These are our calculations from the published terms, not quotes.
Each calculation excludes media. Meta's ad pricing page says the advertiser sets a daily or lifetime budget, so a fee of 10% of spend sits on top of the money you put behind ads. Meta's minimum budgets help page says Ads Manager requires a minimum budget that varies by country and objective, and shows an alert when a budget is too low. The same page says that with a cost per result goal, your daily budget should be at least five times that goal. That matters if a contract ties fees to a target cost per acquisition: as an illustration, a $40 target implies at least $200 a day.
What belongs in a performance clause?
Define the result before you sign. Name the metric the fee follows, such as return on ad spend, cost per acquisition or revenue, plus the attribution method and window. Say whether the result comes from Meta's reporting or from your sales records, and who has the final count. Then state the minimum fee, what happens when the metric is missed, and how media spend is paid.
Keep ownership of the ad account in your business portfolio, and give the agency access with a defined role, as Meta's partner access help describes. Ask for an exit clause that ends the engagement without losing access to the account, the pixel or the creative assets. A revenue-partnership deal, such as KlientBoost's, needs the same protections.
When is pay-for-performance a poor fit?
Percentage models suit a large, steady spend, and below the minimums the fee dominates the cost. Performance models also depend on tracking. If conversions are measured badly, the fee follows bad data. A performance-linked fee is also not automatically a low-commitment pilot, as TubeScience's spend expectation shows.
If you would rather avoid a percentage of spend, a flat monthly fee such as the one MetaAdsAgency lists may be easier to model. Its Growth plan is $2,400 a month billed yearly ($3,000 billed monthly) for spend up to $50,000, with no setup fee or percentage of spend, though the company says its plans are built for brands spending $20,000 a month and more. Our Facebook agency pricing guide helps you put the models on the same month of spend, and our agency selection guide covers the questions to ask before you sign.

- Define the metric, attribution window and minimum fee in the contract, and keep the ad account in your business portfolio.
FAQ
What is performance-based pricing for an ad agency?
It is a fee tied to something the agency is measured on, such as spend, results or an incentive. Three forms are common: a percentage of ad spend, a retainer with a performance bonus and a production fee linked to results. Each moves risk differently, so read the clause rather than the label.
Does a performance agency pay for my ad spend?
Generally no. A percentage-of-spend fee is charged on top of the media you buy, and MetaAdsAgency says ad spend is paid directly to Meta. Meta's ad pricing page says the advertiser sets the daily or lifetime budget. Before you compare quotes, add the media budget to any fee that excludes it, and confirm in writing whether a quoted figure includes media.
Is a percentage of ad spend cheaper?
It depends on the spend. At small budgets, a fixed minimum such as Adside AI's $3,500 dominates the cost, and at large budgets the percentage grows with spend. Run the arithmetic at your expected monthly spend before choosing.
Who should own the ad account?
You should. Meta's guidance is to keep the ad account, pixel and Pages in your own business portfolio and give the agency access with a defined role. Ask for the role, the assets it can change and when access ends, in writing.
