How much does an Amazon agency cost in 2026?

“Book a call to find out” is not a price.

If you’re evaluating Amazon agencies in 2026, you’ve probably noticed that almost nobody publishes numbers. We do — our bands are on our homepage — so this guide can be specific in a way most agency content can’t afford to be. Here is how the market actually charges, what the fee should buy, and where the traps are.

The four pricing models

Flat monthly retainer. A fixed fee for a defined scope — common for full-service account management. Full-service retainers for established brands commonly run from a few thousand dollars a month at the low end to $15,000+ for large catalogs with multi-marketplace scope. The model is predictable; the risk is scope drift, where the retainer stays flat while the attention quietly shrinks.

Percentage of ad spend. Standard in PPC-only engagements, typically in the 5–15% range depending on spend level. The structural problem: the agency is paid more when you spend more, whether or not the spend is efficient. If your incentive is a lower TACoS and theirs is a higher budget, the model is fighting you.

Percentage of revenue. Usually 3–10% of Amazon revenue, sometimes with a floor. It aligns better than %-of-spend, but watch what “revenue” means — total account revenue includes the sales you’d have made anyway.

Performance hybrid. A base retainer plus a bonus tied to an agreed metric — incremental GMV, TACoS improvement, or profit. Hardest to negotiate, best-aligned when the baseline and attribution are defined honestly upfront. This is what we use on Growth and Scale engagements, and we’d argue it’s what you should push any agency toward.

Our published numbers, as an anchor

We publish our bands because a market where every price is “it depends” is a market that favors the seller:

• Launch — $3,000–$5,000/mo plus a one-time setup fee. New brand or first year on Amazon: Brand Registry, first 10 listings, launch PPC plan, storefront. One principal operator, up to 10 parent ASINs.
• Growth — $6,000–$12,000/mo plus a performance bonus on incremental GMV or TACoS improvement. Most engagements sit here: one principal plus Shenzhen team support, up to 40 parent ASINs.
• Scale — custom, priced against attributed GMV and retained operating scope. Multi-marketplace (US + CA/UK/DE/JP), DSP, dedicated team.

You don’t need to hire us for these numbers to be useful. Take them into any negotiation as a calibration point: if a quote is far below, ask what’s been cut; if far above, ask what you’re getting that a senior-operator model doesn’t already include.

What actually drives the price

Four things move the number honestly: catalog size (40 parent ASINs is a different job than 8), ad spend (managing $200K/mo is a different job than $15K/mo), marketplace count (each locale adds listings, compliance, and coordination), and operating scope (is the agency drafting your inbound plans and handling account-health incidents, or just touching bids?).

Be suspicious when a quote scales with things that don’t change the work — your funding round, your category’s glamour, or how big you said your ambitions were on the discovery call.

The questions that expose a bad deal

Ask every agency you evaluate:

1. “What did you ship for a comparable client last week?” Specific answer with evidence, or deflection? This single question filters more agencies than any RFP.
2. “Who exactly runs my account, and how senior are they?” If the pitch team and the delivery team are different people, price the delivery team.
3. “What happens at my next milestone?” Model the fee at 2× your current revenue or spend. %-based models can double your cost without doubling the work.
4. “What’s the exit?” Contract length, out-clause, penalties. Our standard is 6 months with a 60-day out after the first 90 days and no early-termination penalty in good faith — anything much stricter deserves an explanation.

When you shouldn’t hire an agency at all

Below roughly $150K/mo GMV, an in-house operator with a focused tool stack usually beats any agency on cost-effectiveness — including us. We review $150K–$300K/mo case by case, and about half of our own audit calls end with us recommending the brand stays in-house or with their current setup.

The best-fit case for a full-service agency is a brand at $300K+/mo that has hit the ceiling of “one operator plus tools” — typically somewhere between $500K and $1M/mo — where the constraint is no longer effort but operating judgment across listings, ads, inventory, and account health at once.

The Operator Read

Price is only meaningful attached to scope, seniority, and incentives. A $4K retainer with a junior pool and no exit is more expensive than a $10K engagement with a named senior operator and a performance bonus that pays only on incremental results.

Get the model, the scope, the person, and the exit in writing. And if an agency won’t tell you what things cost until you’ve sat through a pitch — you’ve already learned the most important thing about how they operate.
