Key takeaways
- Most provider pages list services but hide price, term and ownership, so ask for all three in writing.
- Flat retainers keep the provider focused on profit, while percentage fees grow with spend or revenue.
- Keep your own 90-day baseline so you can judge the provider on TACoS, profit and organic share.

Based on the ranking provider pages we read in November 2026. PPC Spider full-service is a flat $1,500/mo.
What Amazon marketplace management services include
We read the pages that rank for this search, from large agencies to virtual assistant shops. Their service lists look almost identical. The difference between providers is not the list. It is who does the work, how it is priced and what happens when something breaks.
A complete service covers the full loop that decides Amazon growth. Advertising buys visibility, listings turn it into sales, sales build organic rank, and stock keeps the whole thing from stalling. A provider that runs only one or two of these parts will hit a ceiling set by the parts it does not touch.
- Advertising: Sponsored Products, Sponsored Brands and Sponsored Display
- Listing SEO: titles, bullets, backend terms and copy that answers shopper questions
- Creative upkeep: images, A+ Content and the Brand Store
- Catalog and account health: suppressed listings, variation fixes, policy notices and cases
- Inventory planning, inbound shipments and FBA reimbursements
- Brand protection: Brand Registry, unauthorized sellers and counterfeit takedowns
- Reporting that connects ad spend to total sales and profit
What most provider pages leave out
Across the ranking pages we read, none published a monthly price and none stated a minimum term, a notice period or what happens to your data on exit. Several led with large client counts or growth percentages that cannot be checked. That is the real gap for a buyer: the information you need to decide is the information missing from the page.
Before any call, write down five questions that a service list never answers. What does it cost per month, in dollars? How long is the first term, and what is the notice period after it? Who owns the Seller Central, Ads and Brand Registry access? What is not included? Which three numbers will the monthly report lead with?
How providers price marketplace management
There are four common models, and each one changes what the provider is rewarded for.
Virtual assistant hours are the cheapest on paper, but you still have to supply the strategy, and quality depends entirely on the person assigned. Percentage of ad spend rewards the provider when spend rises, whether or not that spend is profitable. Percentage of sales rewards revenue even when margin falls. A flat monthly retainer is easiest to budget and leaves the provider no reason to spend more of your money than the profit target allows.
- Hourly or virtual assistant: low price, strategy stays with you
- Percentage of ad spend: fee grows with spend, not with profit
- Percentage of sales: fee grows with revenue, not with margin
- Flat retainer: fixed cost, incentive tied to results
Worked example: what the pricing model really costs
These numbers are illustrative, not a real account. Take a brand selling $60,000 a month on Amazon with 20 ASINs and $9,000 of monthly ad spend.
On a 15 percent of ad spend model, the fee is $1,350 a month. If the brand doubles spend to $18,000 to chase a seasonal peak, the fee rises to $2,700, even if half of the extra spend loses money. On a 5 percent of sales model, the fee starts at $3,000 and grows with every sale, including organic sales the provider did not create.
On a flat retainer such as PPC Spider full-service at $1,500 a month, the fee stays at $1,500 at both spend levels, because the plan covers up to 25 ASINs and $20,000 of monthly ad spend. The point is not that flat is always cheapest. It is that you can see the cost before you sign, and the provider gains nothing from spending more.
Fees on the Amazon side matter too. Amazon said its US FBA fees would rise by an average of $0.08 per unit from January 15, 2026. For the same illustrative brand shipping 8,000 units a month, that is roughly $640 a month of extra cost that a good management team should already have built into ACoS targets and prices.
What PPC Spider charges for Amazon management
PPC Spider publishes every price. Full-service Amazon management is a flat $1,500 a month for up to 25 ASINs and $20,000 of monthly ad spend. It includes a dedicated account manager, ads manager, operations and creative teams, a shared Slack channel, bi-weekly meetings with action items, weekly and monthly reports, PPC, listing SEO, account health, inventory planning and reimbursements, A+ and Brand Store upkeep, brand protection, a promotions calendar and SpiderOS access.
Accounts above 25 ASINs or $20,000 of ad spend, multi-brand, 1P and 3P or international businesses get a custom Enterprise quote. If you only need one department, Amazon PPC management starts at $995 a month and ongoing listing SEO at $950 a month.
The first term is 90 days, then month to month with 30 days notice. There is no percentage of ad spend. You own the accounts and the data: the team works inside your Seller Central and Ads accounts as users you can remove at any time, and the SpiderOS login is yours.
Contract, access and ownership terms to check
This is where buyers get hurt, and it is the part competitor pages skip. A provider should never ask for your primary Seller Central login. Amazon lets you add users with their own credentials and set permissions, so you can remove them in one click.
Ask in writing who owns the ad account history, the listing copy and the creative files. If the answer is anything other than you, walk away. Ask for the exit process as well: how long the handover takes and what documents you receive.
- Separate user logins, never a shared password
- Brand Registry stays in your name
- Creative files and keyword maps handed over on exit
- Notice period stated as a number of days
- No fee tied to ad spend or to organic sales
Checklist: steps to compare marketplace management services
Run these six steps on every provider you shortlist, including us. Each one has an owner and a number that tells you whether it worked.
- Founder or ecommerce lead: in Seller Central, open Business Reports and record last 90 days sales, units and sessions per ASIN. Metric: a baseline you can compare the provider report against.
- Finance lead: in the Amazon Ads console, export 90 days of spend and sales, then calculate TACoS as ad spend divided by total sales. Metric: TACoS is the number the provider must improve, not ACoS alone.
- Founder: send each provider the same five questions on price, term, notice, ownership and exclusions. Metric: written answers with dollar amounts and day counts, received before a sales call.
- Ecommerce lead: ask for a live demo of the reporting dashboard, not a PDF sample. Metric: you can see profit after fees and organic share of sales per product.
- Ops lead: ask how the provider handles a product that is close to stocking out. Metric: a named rule, such as throttling ads on that ASIN, not a general promise.
- Founder: after month one, compare the provider report against your own baseline. Metric: wasted spend cut, listing fixes shipped and stock risks flagged, all with dates.
When marketplace management is not the right fit
A monthly service is not for every seller. If your catalog is a handful of ASINs selling a few thousand dollars a month, a $1,500 retainer can be larger than the profit it could add. Start with a one-time listing rewrite or a free audit and revisit management once the listings convert.
It also makes less sense if you already have a strong in-house team that only lacks one skill. In that case buy that one department, such as PPC or listing SEO, rather than handing over the whole account. And if your margins cannot support advertising at all after fees, fix pricing and costs first, because no agency can buy profitable sales on a product that loses money per unit.
