One Amazon PPC proposal lists a monthly retainer. Another charges a percentage of ad spend. A third combines a base fee with a variable charge. Comparing the headline numbers will only get you so far: you also need to know what each provider will do and what you will pay separately.
Start by asking every provider for the same three things: a fee calculation, a written scope and a total-cost example at your planned ad spend. That makes the proposals easier to compare before you commit.
We sell Amazon PPC management, so we have a commercial interest in this decision. This guide uses our published starting prices for transparent examples. It does not claim an industry average or rank agencies by price.
Separate the management fee from the advertising budget
Your advertising budget pays for advertising. Your management fee pays a provider to manage the agreed work.
For example, Amazon describes Sponsored Products as cost-per-click advertising: you pay when someone clicks an ad. That advertising charge is separate from an external agency's service fee. See Amazon Ads' explanation of Sponsored Products.
When planning your budget, write out:
Advertising spend + management fee + separately charged tools or services = the combined cost of the agreed advertising work.
This is not your total cost of selling on Amazon. Product costs, selling and fulfillment fees, returns and other business expenses still matter. Include any applicable taxes in your own budget as well.
Ask the provider to show both the first month and a normal ongoing month. A setup charge, initial audit or creative project can make those totals different.
Understand the fee calculation
These are structures to check for in proposals, not a claim about how often agencies use each one.
| Fee structure | How to read the quote | What to clarify |
|---|---|---|
| Flat monthly fee | A stated amount for an agreed scope | Which changes in products, marketplaces or workload trigger a new quote? |
| Percentage of ad spend | The agreed percentage multiplied by the defined spend | Is there a minimum? Which accounts and advertising products count toward spend? |
| Minimum or percentage, whichever is higher | Calculate both amounts and use the larger one | Is the minimum a floor, or is the quote actually charging a base fee plus a percentage? |
| Base fee plus percentage | Add the fixed amount to the percentage charge | What does the base cover, and what causes the variable charge to rise? |
| Fee with a performance component | A fixed or variable fee tied to an agreed result | How are the result, baseline, measurement period and adjustments defined? |
The difference between “or” and “plus” matters. A minimum of $999 or 10% of spend, whichever is higher, is a different calculation from $999 plus 10% of spend.
For a percentage-based proposal, ask whether the calculation uses actual billed spend or another figure. Also confirm currency, invoicing dates, treatment of credits and what happens during a partial month. Those details should be clear before an invoice arrives.
A performance-linked fee needs equally clear definitions. “Growth” could refer to total revenue, attributed ad sales or something else. Ask how refunds, discounts, stockouts and changes in product range affect the calculation. A fee tied to sales does not automatically mean a fee tied to profit.
Worked examples using Maester's starting pricing
Our published starting model is $999 per month or 10% of monthly ad spend, whichever is higher. Ad spend is separate. We confirm the scope and final quote before work begins.
| Monthly ad spend | 10% of spend | Starting management fee | Ad spend plus management fee |
|---|---|---|---|
| $5,000 | $500 | $999 | $5,999 |
| $10,000 | $1,000 | $1,000 | $11,000 |
| $15,000 | $1,500 | $1,500 | $16,500 |
These are illustrative calculations, not recommended budgets, typical client spending or performance forecasts. They exclude separately quoted work and applicable taxes.
At $5,000 in spend, the minimum applies. At $15,000, the percentage produces a higher fee, so the starting management charge is $1,500. You do not add another $999 to that amount.
For your own comparison, ask every candidate to calculate its fee at your expected spend and at a higher-spend scenario. This shows how the bill would change if you increased advertising. It does not mean you should increase it.
Compare what the fee actually covers
Two proposals can use the same price and cover different work. Give each provider the same account outline: marketplaces, product range, current advertising, priorities and the work your own team already handles.
Then check these areas.
Campaign work
Ask which advertising products and accounts are included, whether setup or restructuring is covered, and who reviews targeting, search terms, bids and budgets. Confirm whether seasonal planning and new-product campaigns are included or quoted separately.
A list of tasks is useful, but ask how priorities are chosen and how decisions are explained. A promised number of account changes is not, by itself, evidence of better management.
Listing and creative work
Ask what happens when the agency identifies weak product images, unclear copy or an unavailable product. Will it fix the issue, brief your team or quote a separate project?
At Maester Solutions, PPC management covers advertising. Seller Central operations, new listing images and new creative or copy projects are separate work. If an issue outside advertising is limiting performance, we flag it and discuss who will handle the fix.
This distinction matters when comparing a PPC-only proposal with one that also includes account management or design. Our agency, in-house and freelancer comparison covers how to compare the wider delivery arrangements.
Reporting and communication
Agree which reports you will receive, how often you will discuss them and who your contact will be. Ask for an explanation of what changed, why it changed and what needs your decision.
Also confirm who covers the account when the main contact is unavailable. The reporting format matters less than whether it helps you understand the work and decide what happens next.
Tools, access and ending the engagement
Check whether required software is included in the fee or billed separately. Ask which reports and working records you can retain, what the handover includes and when access will be removed if the engagement ends.
Keep budget approval limits explicit. A percentage-based fee rises with spend, so it is particularly useful to agree who can authorize increases. A flat fee also needs clear limits on the scope and decisions the provider can make.

Include the fee when reviewing advertising economics
Amazon defines ACoS as advertising spend divided by attributed advertising sales, expressed as a percentage. That formula does not include a separately invoiced agency management fee.
For an illustrative month with $5,000 in ad spend and $20,000 in attributed sales, ACoS is 25%. Adding a $999 management fee gives $5,999 in combined spend and management cost. Dividing that by the same $20,000 gives approximately 30%.
The second calculation is a separate planning ratio, not Amazon's reported ACoS and not a profit margin. It still excludes product costs, selling fees and other expenses. Attributed sales also do not prove that every purchase was caused by the advertising.
Use this distinction to ask better questions about affordability. A fee can look small next to revenue while still mattering to your margins. Our guide to lowering Amazon ACoS explains why cost targets need business context.
When a smaller engagement or internal management may fit
A monthly agency engagement is one option. If you already have someone who can monitor campaigns and act on the findings, a defined review or specialist project may address a specific gap. Confirm what support is available rather than assuming every provider offers it.
If your total budget leaves little room for both management and advertising, compare a narrower scope or continued internal management. There is no universal spend threshold that makes hiring an agency worthwhile.
The decision depends on the work, your team's capacity, the proposed fee and the economics of your products. None of those can be settled by a percentage alone.
Before you sign, get five answers in writing
- What will the first month and an ongoing month cost at our planned spend?
- Which tasks are included, and which stay with our team or cost extra?
- Who manages the account, explains decisions and covers absences?
- Who approves budget increases and changes in scope?
- What happens to access, records and unfinished work when the engagement ends?
A clear proposal should let you answer those questions without filling gaps yourself.

Frequently asked questions
How much does Amazon PPC management cost?
The amount depends on the provider's pricing model and agreed scope. Maester Solutions starts at $999 per month or 10% of monthly ad spend, whichever is higher. Amazon ad spend is separate, and the final quote is confirmed before work begins.
Is the advertising budget included in a PPC management fee?
Do not assume it is. Ask for advertising spend, management fees and additional services to be listed separately. At Maester Solutions, the management fee does not include the advertising budget paid to Amazon.
Is a flat fee better than a percentage of ad spend?
Neither model establishes quality or value by itself. Compare the scope, minimum fee, approval rules and total cost at several spend levels. A flat fee can change when scope changes, while a percentage fee changes with the spend used to calculate it.
Does Amazon PPC management include listing images and account management?
Only if those services are explicitly included in the proposal. At Maester Solutions, Seller Central account management, new listing images and new creative or copy projects are separate from PPC management.
