Questions to Ask Before Hiring an Amazon Agency

TL;DR

What to expect from this article: A working list of the questions that actually separate a strong Amazon agency fit from a costly mismatch, organized around scope, team structure, measurement, and data ownership, plus why most sellers only think to ask them after something has already gone wrong.

Key takeaways:

• Most sellers evaluate agencies on price and pitch alone, when the questions that predict a good outcome are about scope, team structure, and how success gets measured, not the number on the proposal.

• A written scope of work, not a sales deck, is the only reliable way to confirm what's actually included before you sign, since verbal pitches and signed contracts frequently diverge on exactly the services a brand assumed were bundled.

• 61% of Amazon sellers who switched agencies in the past two years cited "unclear scope of services" as a top-three reason for leaving, according to Jungle Scout's 2026 Amazon Benchmark Report, a gap that almost always traces back to questions that weren't asked at signing.

• Asking how an agency measures success, and by whom, is the single fastest way to expose whether a fee is tied to your profit or just to your ad spend.

• Data and account access questions matter as much as pricing questions: an agency that doesn't give full client-side access to Seller Central and Advertising Console is building a form of lock-in worth pricing into the decision before you sign, not after you try to leave.

What questions should you ask before hiring an Amazon agency?

Before hiring an Amazon agency, ask direct questions about scope, team structure, how success is measured, and data ownership, because a sales pitch and a signed contract frequently describe two different services, and the mismatch usually only surfaces months in. Most sellers spend their evaluation time comparing price and case studies, which answers "is this affordable" and "have they done this before," but leaves the harder question unanswered: will this specific engagement, at this specific scope, actually solve what's currently broken.

The questions below are organized around the four areas where mismatches most commonly happen: what's actually included, who's actually doing the work, how results get measured, and what happens to your account and data if the relationship ends.

What should you ask about pricing and scope before signing?

Ask for a written, line-item scope of work before signing, and confirm which services are bundled into the base fee versus billed separately, because "full-service" isn't a standardized term and the same monthly number can represent very different scopes. Specific questions worth asking directly:

• Is the fee tied to ad spend, a flat retainer, or a hybrid, and what does that mean for how your incentives are structured? A percentage-of-spend model earns more as your budget grows, whether or not that growth is profitable.

• What's included in the base fee, and what's billed as an add-on? DSP management, creative production, A+ Content builds, and account audits are the services most commonly carved out of a headline number.

• What happens if my catalog size, ad spend, or scope changes mid-contract? Get the re-pricing terms in writing before you need them, not after.

• Can I see a sample scope-of-work document from a comparable client? A written scope from a real client tells you far more than a slide describing services generically.

Get this in writing before comparing the number on the invoice. Two proposals quoting the same monthly fee can be selling meaningfully different products.

What should you ask about who's actually doing the work?

Ask exactly who will be working on your account, how many other accounts they manage, and whether the team spans the specialties your brand actually needs, because "full-service" pricing sometimes funds a small coordinated team and sometimes funds one generalist stretched across every function. Questions that surface the real staffing model:

• Who is my day-to-day point of contact, and what's their background? A named account manager with visibility into strategy is different from a rotating support queue.

• How many accounts does that person or team currently manage? An account manager spread across 20 brands has less bandwidth per account than one managing five.

• Does my account get access to specialists in PPC, listing, and catalog, or one person covering all three? If your brand has gaps in more than one function, one generalist is unlikely to close all of them at depth.

• What happens if my main point of contact leaves the agency? Ask about handoff process and continuity before it becomes a live problem.

What should you ask about how success will be measured?

Ask how the agency defines and reports success, and whether that definition connects to your contribution margin or just to ad-platform metrics like ACOS and ROAS, because those metrics can look healthy while the business isn't actually becoming more profitable. Questions worth putting directly to a prospective agency:

• What metrics will I see in a monthly or quarterly report, and who decides which ones matter? If the answer is exclusively ACOS, ROAS, and impressions, ask how those tie back to margin.

• What decisions were made on comparable accounts that clients wouldn't have made themselves, and why? This separates active strategy from automated bid adjustments dressed up as management.

• How do you attribute lift to your own work versus organic or seasonal movement? An agency that can't explain its attribution logic can't prove its fee is earning its keep.

• What does a bad quarter look like in your reporting, and how would I find out? An agency willing to describe how they surface their own underperformance is a different kind of partner than one who only reports wins.

What should you ask about account access and data ownership?

Ask for full client-side access to Seller Central, Advertising Console, and all underlying reporting before you sign, and confirm in writing what happens to that access and your historical data if the relationship ends, because an agency that controls the account rather than the brand is building a form of lock-in that only becomes visible when a brand tries to leave. Direct questions to ask:

• Will I have admin-level access to my own Seller Central and Advertising Console accounts throughout the engagement? Not read-only, not agency-owned logins, full client-side access.

• What happens to my campaign history, creative assets, and reporting if I switch agencies or take the work in-house? Get a specific answer, not a general assurance.

• Is there a transition period built into the contract, and what does the agency owe me during it? Some agencies scale down support the moment a client gives notice; others maintain full service through a defined handoff window.

• Are there exit fees, minimum terms, or auto-renewal clauses I should know about now? These terms matter far more at the point of leaving than they do at the point of signing, which is exactly why they need to be asked before signing.

What questions separate a real full-service agency from one that just says it is?

The clearest test is whether an agency can answer these questions specifically, with real numbers and named processes, versus generically, with reassurance and case studies that don't map to your account. A generic "we've helped hundreds of brands grow" answer to a scope or measurement question is itself the answer: it means the agency hasn't thought through your specific situation, or would rather you didn't ask.

A supplements brand evaluating three agencies at similar quoted retainers, all around $4,000 to $4,500 a month, asked each one for a written scope-of-work document and a direct answer on how DSP, A+ Content, and catalog audits were billed. Two of the three agencies' written scopes revealed that catalog work and A+ Content builds were carved out as separate line items not mentioned in the initial pitch, work that would have added an estimated $1,500 a month once actually needed. The brand signed with the agency whose written scope matched its verbal pitch exactly and included a defined 48-hour issue-response window in the contract, avoiding what would likely have been over $18,000 in undisclosed first-year costs across the other two options.
