How much does an Amazon agency cost? Retainers, revenue share and the alternatives
Agencies' own 2026 price guides put Amazon agency retainers at about $1,500 to $25,000 or more a month, rising with brand size and scope. Percentage models usually run 10-20% of ad spend or 3-10% of Amazon sales, often with a $1,000-$5,000 setup fee, and ad spend is paid on top. Reseller accelerators work differently: they buy your stock at wholesale and keep the spread to retail.
- SupplyKick's 2026 pricing guide (updated September 14, 2026) lists retainers from $1,500-$3,000 a month for brands under $250K a year up to $15,000-$25,000+ for $10M+ or multi-marketplace brands.
- SupplyKick, Canopy Management and SalesDuo each put percentage-of-ad-spend fees at 10-20% of monthly Amazon ad spend. The ad spend itself is paid on top.
- SupplyKick puts percentage-of-sales fees at 3-10% of Amazon revenue and setup fees at $1,000-$5,000. Marknology publishes its own rate: from $2,000 a month plus 3% of Amazon sales in any month that reaches $10,000.
- Pattern's 3P Accelerator buys inventory upfront. Its Form 10-K says brands reimburse its advertising costs and put more than $220 million of ad spend through its platform in 2025.
- At May 2025 BLS medians, a marketing specialist ($78,760) and a logistician ($82,320) cost about $208,000 a year once benefits other than paid leave, which a salary already covers, are added.
- For an example brand with $3M a year in Amazon sales and $30,000 a month in ads, published rates come to $108,000-$900,000 in agency fees over three years, before ad spend.
Most pages that answer this question are written by agencies pricing their own service. We are a tech agency too, and we build one of the alternatives compared below, so weigh our view accordingly. Every agency figure here comes from an agency's own published 2026 guide, linked and checked November 6, 2026, and our editorial standards explain how we check sources. We explain how reseller accelerators earn money, but we never estimate what a named company's model costs a brand. Our own prices are not on this page.
How do Amazon agencies charge?
Most Amazon agencies bill in one of four ways, or a mix of them. Canopy Management, an Amazon agency, names three fee structures that dominate PPC management: a percentage of ad spend, a flat monthly retainer, and a hybrid of a base fee plus a percentage or a performance component (checked November 6, 2026). SupplyKick's 2026 pricing guide adds a fourth, a percentage of your Amazon revenue. SupplyKick calls the flat retainer the most common model overall, while Canopy says a percentage of ad spend is the most common for advertising work.
Each mechanism pays the agency for something different, and that matters more than the headline number:
- Flat retainer. A fixed monthly fee for an agreed scope. It is predictable, but the fee does not move when results do, so the scope has to be written down.
- Percentage of ad spend. The fee rises with the budget. Canopy itself points out that the agency earns more when you spend more, whether or not the extra spend is profitable.
- Percentage of sales. The fee rises with revenue, not margin. SupplyKick's guide warns that sales from low-margin products or unprofitable promotions still raise the fee, and advises negotiating a cap or a tiered rate.
- Hybrid. A lower base plus a share of sales above a threshold, or a bonus tied to agreed metrics. It is the hardest to compare, because the threshold does most of the work.
A reseller accelerator is a different business: it buys your inventory and earns the gap between wholesale and retail, so there is no fee to compare and its cost has to be measured another way. We cover it separately below. Our accelerator, aggregator and agency comparison explains who holds the seller account in each model.
What do published price ranges look like?
The table below lines up the published ranges for each mechanism and adds a three-year line for one example brand: $3 million a year in Amazon sales ($250,000 a month) and $30,000 a month in ad spend, both held flat for three years. It is an illustration, not a client, and it assumes no growth. The agency figures are management fees only. The $1,080,000 of ad spend over those three years is paid to Amazon on top, whichever agency model you choose.
| Mechanism | How the fee is set | Published 2026 ranges (checked Nov 6, 2026) | Three years for the example brand | What pushes it up |
|---|---|---|---|---|
| Flat retainer | Fixed monthly fee for an agreed scope | $1,500-$3,000 a month under $250K a year, $3,000-$7,500 at $250K-$2M, $7,500-$15,000 at $2M-$10M and $15,000-$25,000+ at $10M+ or multi-marketplace (SupplyKick); $1,000-$5,000 for PPC management at small and mid-size brands (Canopy) | $270,000-$540,000 at SupplyKick's $7,500-$15,000 tier | Scope added mid-contract; creative and tools billed separately; extra marketplaces |
| Percentage of sales | A share of Amazon revenue | 3-10% (SupplyKick), a range Marknology also cites from SupplyKick | $270,000-$900,000 at 3-10% | Revenue growth, including low-margin sales and promotions, unless the rate is capped |
| Percentage of ad spend | A share of monthly Amazon ad spend | 10-20% (SupplyKick, Canopy and SalesDuo), and SalesDuo adds that many agencies set a minimum fee of $1,500-$2,500 a month | $108,000-$216,000 at 10-20%, usually for advertising work only | Bigger budgets and seasonal ramps |
| Hybrid | A lower base plus a share above a threshold | The example in both SupplyKick's and SalesDuo's guides: $3,500 a month plus 4% of monthly sales above $400,000. One real rate card: Marknology, from $2,000 a month plus 3% of that month's Amazon sales in any month that reaches $10,000 | $126,000 on the example, because sales never pass the threshold (each month at $100,000 above it would add $4,000); at least $342,000 on Marknology's starting rate | Where the threshold sits and which sales count |
| Reseller spread | No management fee; the reseller buys at wholesale and sells at retail | No published rate; the spread is set in each contract | Not a fee line: compare contribution margins with the formula below | Wholesale price, ad reimbursements, returns and buybacks |
| In-house team | Salaries plus benefits | BLS May 2025 medians: marketing specialist $78,760, logistician $82,320; benefits other than paid leave 22.5% of compensation (June 2026) | About $624,000 for those two roles | Headcount, recruiting and tools |
| Owned system | Build once, then hosting and maintenance, plus any base license on the terms agreed before the build | No published market rate; priced from a written scope | Build + three years of hosting and maintenance + any base license cost on those terms + the people who run it | Custom scope and the number of channels |
Two things stand out. At this brand size, the low end of a full-service retainer and 3% of sales land on the same $270,000, but they behave differently later: a percentage fee grows with revenue and a retainer does not. And the smallest line, a share of ad spend, usually buys advertising management only. Listings, creative, account health and inventory planning are billed separately or left out, so compare like with like before comparing numbers.
The fee is rarely the whole bill. SupplyKick's guide lists one-time onboarding fees of $1,000-$5,000, product photography at $200-$800 per ASIN, and early-termination penalties of one to three months of retainer on six- or twelve-month contracts. It also says each extra international marketplace adds 30-50% to the base retainer, and that agencies typically charge 15-30% more for Vendor Central (1P) accounts than for equivalent Seller Central work. Marknology's rate card shows what a published exclusion list looks like: ad spend, software (passed through at cost), photography and video and fulfillment all sit outside its fee, and each extra international marketplace adds a $2,000 one-time setup plus a monthly fee quoted with the plan.
What would the same fee models cost at three sales levels?
A fee model that looks cheap at one size can be the expensive one at another. The table applies the published 2026 figures to three illustrative brands, holding sales flat. These are not client numbers or quotes. Marknology's column is a floor, because its retainer starts at $2,000 and is sized to the work, so a larger account would likely be quoted more.
| Monthly Amazon sales (illustrative) | SupplyKick's retainer tier | 3-10% of sales | Marknology's starting rate ($2,000 + 3%) | SupplyKick's 2-5% rule of thumb |
|---|---|---|---|---|
| $50,000 ($600K a year) | $3,000-$7,500 | $1,500-$5,000 | From $3,500 | $1,000-$2,500 |
| $250,000 ($3M a year) | $7,500-$15,000 | $7,500-$25,000 | From $9,500 | $5,000-$12,500 |
| $1,000,000 ($12M a year) | $15,000-$25,000+ | $30,000-$100,000 | From $32,000 | $20,000-$50,000 |
Three things follow from the arithmetic. At $50,000 a month, SupplyKick's own retainer tier comes to 6-15% of sales, above its own 2-5% rule, so a smaller brand has the least room for a full retainer. At $250,000 a month the models overlap, and scope decides which is cheaper. At $1,000,000 a month, even 3% of sales ($30,000) passes the $25,000 where SupplyKick's top tier opens, so a percentage fee is the first thing to cap. Run your own sales through the same columns before you compare quotes.
What do reseller accelerators cost you?
A reseller accelerator earns its money mainly from a spread, not a management fee. It buys your products at a wholesale price, sells them on its own marketplace accounts and keeps the difference between that price and retail. That makes it the merchant of record, the seller the shopper buys from. The word accelerator also covers fee-based programs, so read the contract rather than the label.
Pattern is a public company, so its model is documented. Its 3P Accelerator page says "We purchase your inventory upfront" and describes Pattern handling forecasting, content, listing optimization, ad strategy and customer service; it also says brands set the strategy and have the final say on major decisions (checked November 6, 2026). Pattern's Form 10-K for fiscal 2025 says it generates the substantial majority of its revenue from consumer product sales on marketplaces and is the principal in the vast majority of its contracts. Its 10-Q for the quarter ended September 30, 2026, filed November 5, says it sells products from more than 275 brands and operates across more than 80 marketplaces.
Some costs stay with the brand. The same 10-K says brands reimburse Pattern for advertising costs incurred in selling their products, and that brands put more than $220 million of ad spend through its platform in 2025. Most brands must reimburse it for products customers damage or return, and brands carry promotion and buyback obligations. A substantial portion of its brand agreements allow termination for convenience on 60 days' notice. Its 1P Accelerator works differently again: Pattern does not buy inventory, and brands pay platform and service fees. Our Pattern comparison goes further.
Some resellers pay for ads themselves. MarketLeap's FAQ says it earns a margin between the wholesale price it pays and the retail price it sells at, charges no monthly retainer or percentage of revenue, funds all ad spend from its own margin, and runs a rolling 30-day contract (checked November 6, 2026). MarketLeap is based in Luxembourg and describes itself as a wholesale distributor and marketplace operator rather than an agency.
Because the main cost is not a fee, it shows up as margin you no longer earn, spread across every unit the reseller sells. We do not estimate any reseller's spread, and it varies by contract. Ask for the wholesale price in writing, then put both sides through the same formula:
Reseller cost per unit = your retail contribution margin − your wholesale contribution margin
Your retail contribution margin is the retail price minus landed cost, marketplace fees, fulfillment and storage, returns and the ad spend it takes to sell a unit. Your wholesale contribution margin is the wholesale price minus landed cost and whatever the contract still bills back to you: ad reimbursements, returned units, promotions and buybacks. Multiply the gap by three years of units, then subtract the team and working-capital costs you would no longer carry. A reseller that buys upfront also pays you sooner, which counts if cash is tight.
What does an in-house team cost?
Hiring swaps the agency fee for payroll. Take two roles that cover the core of full-service agency work: a marketing specialist to run ads and listings, and a logistician to plan inventory and suppliers. The Bureau of Labor Statistics puts the May 2025 median annual wage at $78,760 for market research analysts and marketing specialists and $82,320 for logisticians. Benefits made up 30.0 percent of private-industry employer compensation costs in June 2026, and 7.5 points of that was paid leave, which an annual salary already pays for (all checked November 6, 2026). So a salary is divided by 0.775, not 0.70, the same method our operations cost calculator uses.
At those medians the two roles cost $161,080 in wages and about $208,000 a year with benefits, or about $624,000 over three years. SupplyKick's guide lands in the same range: $161,000-$268,500 a year for a two-person team with tools and freelance creative. Both leave out recruiting, a manager and cover when someone leaves, and a median salary buys a median hire, not necessarily one with Amazon advertising experience. Our in-house team comparison works through the engineering side of the same decision.
What does an owned system cost over three years?
An owned system replaces part of the monthly service fee with software that runs on your own accounts. Its cost has a different shape: much of it is the build, paid once, then hosting and maintenance, plus the Growth OS base license on terms agreed before the build. Ad spend is the same whichever way you manage it, so leave it out unless a model changes who pays it.
Owned system, three years = one-time build + three years of hosting and maintenance + the base license, on the terms agreed before the build + the people who still run it
Each term comes from a quote, not a market rate. With us, custom modules and AI agents are scoped in an architecture doc with a fixed price and go-live date, and base license terms are on request. Our SP-API development cost guide shows the build and maintenance ranges we see in our own projects: our experience, not a price list. To run your own numbers, the operations cost calculator sets agency, in-house and owned-system costs side by side over three years, from your own quotes, with BLS pay figures as the only defaults. If what you need is one workflow automated rather than a whole system, our guide to ecommerce workflow automation cost has a cost-driver worksheet for scoping it.
Two caveats. Software does not replace judgment: someone still sets strategy, approves purchase orders and decides where the ad budget goes, whether that is your own operator or an agency working alongside the system. And a build is only worth it if it takes over work you pay for today. Measuring that needs profit by SKU after fees and ads. For SellerDrive, an Amazon account-management firm, we built an analytics panel that combines SP-API order and finance data with Advertising API data, including a profit and loss statement that computes fees Amazon's reports do not provide.

Which model fits your stage?
No model is right for every brand; the fit depends on your sales, your channels and who you already employ. The table sums up where each one usually fits, based on the costs above. If SaaS tools are the alternative you are weighing, our SaaS stack comparison covers the subscriptions and usage tiers that raise their price as you grow.
| Where you are | Usually the better fit | Why |
|---|---|---|
| Under about $250,000 a year, one marketplace | SaaS tools and your own time, or an entry-level retainer | A $1,500 monthly retainer is $18,000 a year, more than 7% of $250,000 in sales |
| Growing on Amazon, ads are the main lever, short of hands | An agency on a flat retainer or a share of ad spend | Specialists from day one, and the accounts stay yours if they are registered to your company |
| Several marketplaces, with ops work that grows with each channel | An owned system, with an agency or an in-house specialist for strategy | SupplyKick's guide says each extra international marketplace adds 30-50% to a retainer; software can carry the routine work as channels are added |
| You want out of daily marketplace work and accept a wholesale margin | A reseller accelerator | It runs the operation; you give up the retail margin and the seller role |
| You sell wholesale to Amazon (1P) | Pattern's 1P Accelerator or an agency | You keep selling to Amazon; Pattern's 1P program does not buy your inventory and charges platform and service fees |
| Software is part of what you sell, and you have a technical leader | An in-house team | You build and keep the capability |
An agency is the better choice when your accounts and systems already work and what you lack is specialist hands, especially in advertising. It starts quickly, needs no build, and a good one brings patterns from many accounts. Size matters too: SupplyKick's own guide advises against hiring an agency below $100,000 a year in Amazon revenue and gives 2-5% of Amazon revenue as a common rule for agency fees. An agency gets expensive when the fee is tied to sales or ad spend and those keep climbing, or when the same routine work is billed every month for years. That is the point to price an owned system against it, or to automate only that one job: send us the workflow in a project brief and we will scope it with a fixed price.
How do you compare quotes fairly?
Put every option on the same footing: three years, the same sales and ad spend, and every line that will actually be billed. A quote that looks cheaper per month can cost more over three years once setup fees, minimums and exclusions are added. The fair comparison is contribution margin after fees, ads, fulfillment and people, not top-line growth. Before you sign, ask each option for the same things:
- A three-year total at your current sales and ad spend, not a monthly headline
- A list of what the fee excludes: creative, A+ content, tools, DSP and other marketplaces
- Setup fees, minimum fees, any cap on a percentage fee and the rate above any threshold
- The notice period, auto-renewal terms and early-termination cost
- Confirmation that your company owns the seller account, the ad account and the creative files
- For a reseller, the wholesale price and every bill-back in writing

Frequently asked questions
Is 10% of sales a normal fee for an Amazon agency?
It sits at the top of the published ranges. SupplyKick's 2026 guide puts percentage-of-revenue fees at 3-10% of Amazon sales and gives 2-5% of Amazon revenue as a common rule for total agency fees; Marknology's own rate card charges 3% of a month's Amazon sales on top of its retainer (checked November 6, 2026). At $3 million a year in sales, 10% is $300,000 a year before ad spend. Ask for a cap or a rate that steps down as sales grow, and whether the fee applies to sales the agency did not influence.
How much does Amazon PPC management cost on its own?
Canopy Management puts professional PPC management at 10-20% of monthly ad spend or a flat retainer of commonly $1,000-$5,000 a month for small to mid-size brands. SalesDuo says growing brands typically pay $1,500-$8,000 a month or 10-20% of ad spend, while Marknology quotes its advertising-only plan to scope and never charges a percent of ad spend (all checked November 6, 2026). Listings, creative and inventory planning are usually extra.
Is ad spend included in an Amazon agency's fee?
No. Management fees are separate from the ad spend you pay Amazon, whichever fee model the agency uses. A $5,000 monthly retainer on $15,000 of monthly ad spend means $20,000 a month leaves the business. Resellers differ: MarketLeap says it funds ads from its own margin, while Pattern's 10-K says its brands reimburse its advertising costs.
Do Amazon agencies charge setup or onboarding fees?
Many do. SupplyKick's 2026 guide lists one-time setup or onboarding fees of $1,000-$5,000 and notes that some agencies waive the fee for a 12-month contract. Marknology's rate card adds a $2,000 one-time setup for each extra international marketplace. Ask what the fee buys: an audit, campaign builds and a written plan, or only account setup.
What does it cost to leave an Amazon agency early?
Check the contract before you sign it. SupplyKick's guide describes early-termination penalties of one to three months of retainer on six- or twelve-month contracts, and notes that 12-month contracts commonly auto-renew unless you cancel 60 to 90 days before the end. Shorter terms exist: Marknology publishes a 90-day minimum, then month-to-month with 30 days' notice. Also confirm that the seller account, the ad account and the creative files stay with your company when the contract ends.
Do Amazon accelerators charge a monthly fee?
It depends on the model. Reseller accelerators earn the spread between the wholesale price they pay you and the retail price: MarketLeap's FAQ says it charges no monthly retainer or percentage of revenue. Pattern's 3P Accelerator buys inventory upfront, while its 1P Accelerator does not buy inventory and brands pay platform and service fees, according to Pattern's 10-K.
My agency bills every month for the same routine work. Can that be automated instead?
Often, one job at a time. Reports, stock alerts, payout reconciliation and listing error checks follow fixed rules, so software can run them on your own accounts while the agency or your team keeps the judgment calls. Price it against what that work costs you over three years. To scope one job, send it through our project brief at /services/workflow-automation.
