Amazon agency pricing at a glance
- Most full-service Amazon agencies charge $2,500–$6,000/month for brands doing $1M–$20M/year
- The three pricing models: flat monthly retainer, % of ad spend (10–20%), or % of revenue (3–8%)
- Flat retainers are usually better — they don't incentivize overspending your ad budget
- A good agency should generate at least 5–10x their fee in incremental revenue
- Watch out for long contracts, % of total revenue pricing, and agencies that own your campaigns
The 3 Ways Amazon Agencies Charge
There's no single standard for Amazon agency pricing. Most agencies use one of three models, and which one you end up with matters as much as the number itself — because pricing models shape incentives.
Model 1: Flat Monthly Retainer
You pay a fixed monthly fee regardless of how much you spend on ads or how much revenue you generate. This is the cleanest model. The agency's incentive is to deliver results — not to inflate your ad spend or tie their fee to revenue growth they might not be responsible for.
Typical range: $1,500–$8,000/month. Most quality full-service agencies for brands doing $1M–$20M/year land in the $2,500–$5,000/month range.
Model 2: Percentage of Ad Spend
You pay a percentage of whatever you spend on Amazon advertising each month — typically 10–20%, with a minimum floor of $1,500–$2,500/month. This model is common among PPC-only agencies.
The problem: it creates a subtle incentive to recommend higher ad budgets. If an agency earns 15% of spend and you're spending $20,000/month, they make $3,000. If they push your budget to $30,000, they make $4,500 — regardless of whether that additional $10,000 was productive.
Be skeptical of agencies on a pure % of ad spend model that are also managing your budgets without a spend cap in your agreement. Always retain approval over major budget increases.
Model 3: Percentage of Revenue
Some agencies charge 3–8% of your total Amazon revenue. This sounds performance-based, but it has a major flaw: they're being paid on revenue you'd generate with or without them. If your brand has strong organic momentum or you've been selling on Amazon for years, you're essentially paying a fee on baseline performance they didn't create.
A cleaner version of this model ties the percentage to incremental revenue above a baseline — but few agencies structure it that way.

What Affects the Price
The range is wide for a reason. These factors push costs up or down:
| Factor | Pushes Price Up | Pushes Price Down |
|---|---|---|
| Number of ASINs | 100+ active SKUs | 5–20 focused SKUs |
| Ad spend volume | $50K+/month in ads | $5K–$15K/month in ads |
| Account complexity | Multi-country, Brand Registry disputes, suppressed listings | Clean account, single marketplace |
| Services in scope | Ads + listings + A+ + Walmart + DSP | PPC only or listings only |
| Agency reputation | Amazon SPN member, proven track record | New or unverified agency |
| Contract length | Month-to-month flexibility | 6–12 month lock-in |
Is an Amazon Agency Worth It?
Do the math. If you're paying $3,500/month, the agency needs to generate roughly $3,500/month in improvement — through lower ACOS, better conversion, recovered suppressed listings, or keyword rank gains that drive organic sales.
For most brands doing over $500K/year, that's not a high bar. A 5-point ACOS improvement on $20,000/month in ad spend is $1,000/month in savings. One recovered suppressed listing might be worth $3,000–$5,000/month in revenue. Improving your main listing's conversion rate from 12% to 16% on 10,000 monthly visitors (at $40 ASP) is an extra $16,000/month in revenue.
The right benchmark: your agency fee should not exceed 10–15% of the incremental revenue and cost savings they're directly responsible for. If it does, something is wrong — either the pricing or the performance.
The case for staying in-house: if you have a dedicated Amazon specialist on staff and your account is running well, you might not need an agency. Where agencies consistently outperform in-house teams is in bid strategy sophistication, keeping up with algorithm changes, and the depth of benchmarking data from managing dozens of accounts across categories.
Red Flags to Watch For
The Amazon agency space has a lot of players who will charge premium fees for junior work. These are the warning signs:
-
They own your Seller Central account or ad campaigns
You should always own your own data. If an agency controls your account and you part ways, you lose your entire campaign history and keyword data. Non-negotiable.
-
12-month contracts with no performance exit clause
A 3-month onboarding period is reasonable. But any agency confident in their results will let you leave if they're not hitting benchmarks. Beware of contracts that lock you in regardless of performance.
-
Percentage of total Amazon revenue (not incremental)
If you're doing $1M/year on Amazon and an agency charges 5% of total revenue, that's $50,000/year for work that might not have moved the needle on your existing baseline.
-
Can't show you real results from comparable accounts
Any agency should be able to show you 2–3 anonymized case studies from brands similar to yours in revenue and category. If they can't, they haven't done it before — or the results weren't worth showing.
-
Your account is handed to a junior account manager on day 1
Ask specifically: who runs my account day-to-day? Is it a senior strategist or an account coordinator? The person you meet in the sales call is rarely the person managing your campaigns.
-
No discussion of your margins or break-even ACOS
A good agency will ask about your margins before talking about ad strategy. If they pitch "we'll get your ACOS to 20%" without knowing your margins, they don't know what they're doing.
How SellTru Prices
We work with brands doing $1M to $20M/year on Amazon and Walmart. Our model is a flat monthly retainer — no percentage of spend, no percentage of revenue. We think the incentive alignment is cleaner, and so do our clients.
What we don't do: we don't publish a price list, because scope varies. A brand with 8 SKUs and a clean account is different from a brand with 200 SKUs, listing suppression issues, and a Walmart expansion in progress. What we commit to: you'll know our number before the end of your first conversation with us. No games.
We're an Amazon Service Provider Network (SPN) member. That means Amazon has verified our practices and our clients. It also means we can escalate account issues faster than non-SPN agencies when something breaks.
One thing we offer that most agencies don't: a free account audit before you engage. We'll pull up your account, tell you what's wrong, and give you a clear picture of what the work looks like — before you decide if we're the right fit. No obligation.
Frequently Asked Questions
Yes, most do. A one-time setup fee of $500–$2,500 is standard for campaign buildout, audit work, and onboarding. Be skeptical of agencies that waive setup fees — it either means they're cutting corners on initial setup or baking it into a higher monthly fee. Setup work takes real hours.
Three months is the minimum to evaluate meaningful results — algorithms take 4–6 weeks to respond to bid changes, and listing optimization takes time to show in conversion data. Six months is reasonable. Twelve months is only fair if there's a performance clause that lets you exit if benchmarks aren't hit. Month-to-month after an initial period is ideal — it keeps the agency accountable.
Amazon SPN (Service Provider Network) membership means Amazon has reviewed and approved the agency's practices. It's not a guarantee of quality, but it is a meaningful bar. SPN agencies also get access to direct Amazon support for account issues, which can be invaluable when there's a suppression or policy problem. It's worth a small premium.
Sometimes. Agencies with available capacity will sometimes reduce the monthly fee in exchange for a longer-term commitment. You can also negotiate scope — if you don't need A+ Content or Walmart management, ask to remove those from the scope and price. What you shouldn't negotiate away: senior account management, reporting cadence, and campaign ownership. Those are worth paying for.
Month 1 is setup and baseline measurement. You should see initial ACOS improvements and structural fixes within 30–45 days. Meaningful revenue impact from listing optimization and keyword rank gains takes 60–90 days. If you're 90 days in and haven't seen any measurable improvement in ACOS, conversion, or organic rank — something is wrong. That's the benchmark, not 6 months.
A consultant typically audits and advises — they tell you what to do and you do it. An agency manages it for you. Consultants tend to cost less ($500–$3,000 for a project) but require internal bandwidth to execute. Agencies cost more monthly but handle execution. For brands without a dedicated internal Amazon resource, an agency is usually the right move.
