Meta Ads Agency Pricing for eCommerce: Retainers, Percent of Spend, and Minimums

Meta ads agencies charge eCommerce brands in three main ways: a flat monthly retainer set by ad spend tier, a percentage of ad spend, or a hybrid with a minimum fee. On the agency pricing pages we checked for this article, published starting fees run from $750 a month to $6,500 plus a percentage of spend, and ad spend is always paid on top. Hayes Media, an eCommerce growth agency that runs Meta ad creative and media buying together for DTC and Shopify brands, doesn't publish an ads price. Its fee is scoped on the discovery call. Whatever you pay, the fee should buy senior media buying, a steady supply of new creative, and reporting in new customer CAC against the target you set.

What does a Meta ads agency cost an eCommerce brand?

It depends on the pricing model and on how much you spend. Every agency below publishes its own numbers, and each one prices something slightly different, so read what's included before you compare the figure.

Here's what each agency's own page said when we checked:

GrossiWeb (flat fee by spend bracket): "$750 a month for accounts spending up to $5,000, $1,500 up to $15,000 and $2,500 up to $30,000", with "video shoots and professional production, quoted separately".

WebFX (greater of a base fee or a percentage): "$975 or 15% of ad spend, whichever is greater" for $1,000 to $30,000 a month in spend, and "$4,500 or 12% of ad spend, whichever is greater" above $30,000. The first month costs $1,975 or $4,250.

AdvertiseMint (percentage of spend): A "25% Agency Rate" at $10,000 to $24,999 a month in spend, stepping down to a "5% Agency Rate" above $1,000,000 a month, with a "$0 Set Up Fee".

Flighted (flat retainer by spend tier): It's "from $5,000 a month" for brands spending "$25K or more a month on ads", with "50+ new ads a month" in the retainer.

Knowlify (creative-led plans): "Plans start at $5,000 a month" for "about 100 video ads a month", with account management available too and media spend paid straight to Meta.

Structured (base plus percentage): It's "starting at $6,500 plus % of spend", for "Brands with $150k (or more) in monthly business revenue".

Those are published starting points. Your own quote depends on your spend and on what's in scope.

What are the three ways Meta ads agencies price their fee?

A flat retainer, a percentage of spend, and a hybrid of the two. Each one pays the agency for a different thing, so the model tells you as much as the number. A few definitions first. Ad spend is what you pay Meta, the management fee is what you pay the agency, and a minimum is the smallest spend, revenue, or fee the agency will take on.

Flat retainer by ad spend tier

You pay a fixed fee each month, and the fee moves to the next tier when your spend crosses a band. GrossiWeb and Flighted both price this way.

It rewards results inside the band. In a made-up tier of $25,000 to $50,000, the agency earns the same whether it spends $26,000 or $49,000 of your money, so there's no reason to push budget for its own sake. The catch is the jump at the next band. Ask what the next tier costs before you sign.

Percentage of ad spend

The fee is a share of what you spend, so it rises and falls with your budget. AdvertiseMint publishes this model, with the rate dropping as spend grows.

It rewards spend. It's cheap to start and it scales with the work, but the agency earns more every time your budget goes up, whether or not the extra spend brings in customers at a cost you can afford. That doesn't make it a bad model. It means you need a scoreboard that isn't spend.

Hybrid with a minimum fee

You pay a base fee or a percentage, whichever is greater, or a base plus a percentage on top. WebFX and Structured both publish versions of this.

It rewards a bit of both. The minimum covers the agency's cost of running a small account, and the percentage takes over as you grow. Work out the fee at today's spend and at the spend you plan to reach, because the model can look like a flat fee early and a percentage later.

Where does creative production sit in the fee?

This is where quotes differ the most, and it matters if you want one team on creative and media buying. On the pages we fetched, creative shows up in three ways.

Included, with a count: Flighted lists "50+ new ads a month" inside its retainer. AdvertiseMint lists "One Video Per Month" at its lowest tier and "Eight Videos Per Month" at its highest, plus "Unlimited Graphic Design Edits".

Billed separately: GrossiWeb plans a creative test each month but quotes "video shoots and professional production" separately.

Creative first, management optional: Knowlify sells plans built around the volume of video ads it makes, and it will manage the ad account too if you want that.

Ask any agency who pays the creators. Flighted lists "creator and influencer fees" under what's not included. Hayes Media sources and briefs creators, and the client pays them directly.

When you compare two quotes, put creative on the same basis. To use made-up numbers, a $5,000 retainer that includes new ads every month and a $3,000 retainer that leaves you to make them aren't the same product. If you're weighing this against hiring, our guide to running ads with an agency or in-house breaks down the roles you'd need.

What should a Meta ads agency fee buy?

At minimum, four things:

A senior person on your account. Ask who makes the budget, scaling, and kill decisions, and how many other accounts that person runs.

A steady supply of new creative. Ask how many new ads you'll get, who makes them, and how they're tested. Our creative testing framework shows what a real testing process looks like.

Reporting against your number. Platform ROAS is a diagnostic rather than a verdict. The agency should report new customer CAC, or incremental ROAS, against the CAC target you give it. Incremental ROAS counts only the revenue that wouldn't have happened without the ads.

Ownership. The ad account, pixel, and creative files should stay in your name.

If your ROAS is already sliding, a cheaper fee won't fix it. Our guide to why Meta ROAS drops covers the usual causes, and what a Meta ads agency actually does covers the job itself.

What does each model cost on the same account?

These are made-up numbers to show the mechanism, not any agency's real prices. Say your brand spends $30,000 a month on Meta today and plans to reach $80,000.

Flat retainer: $6,000 a month up to $50,000 in spend and $9,000 up to $100,000. At $30,000 you pay $6,000, which is 20% of spend. At $80,000 you pay $9,000, which is 11.25%.

Percentage of spend at 15%: $4,500 at $30,000 and $12,000 at $80,000. The rate stays at 15% the whole way.

Hybrid, $5,000 or 10%, whichever is greater: $5,000 at $30,000, which is 16.7%, and $8,000 at $80,000, which is 10%.

The cheapest quote today isn't the cheapest one at the spend you're planning for. Now add the fee to your acquisition cost. If $30,000 of spend brings in 600 new customers, your CAC on ad spend alone is $50. Add the $6,000 retainer and the real cost of each new customer is $60. That fee-loaded number is the one to hold against your CAC target.

How does Hayes Media price Meta ads and creative?

Hayes Media doesn't publish a price for Meta ads or ad creative. The fee is scoped on the discovery call, based on your account, your spend, and how much creative you need. You can take Meta media buying or Meta ad creative on its own, or both from one team.

Hayes Media reports creative and media buying in new customer CAC or incremental ROAS, against the CAC target your brand gives us. We don't set that target. You know your margins, and the target should come from them.

On proof, the homepage says "Our Performance Creative Process has produced winning ads that have spent $100,000's with on-target metrics." and "We run your ads using the media buying strategies that we've refined over 8 years and millions in ad spend." The Remi case study reports "12,400% Revenue Growth" and a "150% ROAS Increase", and Mammoth Headwear reports a "3.3x Conv. Rate Increase". These case studies are published by Hayes Media on its own site, and Hayes Media has no third-party review profile, so weigh them as our account of our work.

If you're comparing named agencies rather than pricing models, see our list of Meta ads agencies for eCommerce. We wrote that list and put ourselves first, and it says so.

When this doesn't apply

An agency fee only makes sense if there's enough spend and enough margin behind it.

Your margin can't carry paid acquisition. Fix pricing or the offer first. No agency fee changes the math of a product that loses money on every first order.

You're still looking for product market fit. Make simple ads yourself, cheaply, until something sells.

You only need email or SMS. That's a different service with different pricing. Our guide to email marketing agency pricing covers what those agencies charge.

You're smaller than the agency usually works with. Hayes Media works with brands doing at least $100K per month in revenue. It's a guideline, not a gate: a smaller brand with a clear budget set aside to scale and real traction on Meta already qualifies.

Get an audit before you compare quotes

The best way to judge any quote, ours included, is to know what your account needs first. On a discovery call we'll audit your Meta account and your current creative, show you where spend is leaking, and scope what the work would cost. No onboarding fees. No lock-in contracts. No junior marketers. Book a discovery call
