How to Manage Your Amazon Agency: A Client’s Playbook for Maximum ROI (2026)

Hiring a good Amazon agency is only half the work. The other half is making sure you give the agency what it needs to do its job well.

Two brands can hire the same agency and still get very different results. One brand may give the agency quick access, clear information, and fast approvals. Another brand may delay decisions, hide important data, or have unclear responsibilities. These small differences can have a big impact on results.

If you are learning how to manage your Amazon agency, focus on what happens after you sign the contract. Get the agency onboarded quickly, agree on clear goals, set a regular communication schedule, decide who is responsible for what, and understand when the partnership is no longer working.

This guide is for brands that are already working with an Amazon agency, including brands that may be wondering if their current agency is still the right partner.

The First 30 Days: Onboarding Your Agency for Speed

Good Amazon agency onboarding should remove unnecessary problems during the first week.

Your agency should not spend its first month asking for account access, basic product information, or old performance data that your team already has.

Give the agency enough access to do the work included in your contract. However, do not give extra permissions that are not needed.

Match account access to the agency’s responsibilities. Keep a record of who has access and review those permissions whenever the agency’s role changes.

You should also explain the business side of your account. This helps the agency make decisions based on profit and business goals instead of only looking at sales or advertising numbers.

Slow onboarding costs money.

Every week the agency waits for account access, margin information, creative files, or approvals is another week when you are paying for work that cannot be fully completed.

A smooth handoff also makes it easier to judge the agency later. You can clearly separate agency performance problems from delays caused by your own team.

Set the Right Goals (and Make Them Measurable)

Choose two or three clear goals that connect directly to your business.

Do not create a scorecard with dozens of numbers that do not clearly show whether the business is improving.

For example, a brand focused on profit may care more about contribution margin and TACoS. A brand launching a new product may care more about category rank and getting new customers efficiently.

The right goals depend on what you hired the agency to achieve.

Do not turn this relationship guide into a pricing or ROI calculation. Use your existing framework for measuring agency ROI / pricing, and then use those agreed goals during every agency review.

The most important thing is consistency. Your agency should clearly know how you will judge its performance before it starts making major changes to the account.

How to Manage Your Amazon Agency: Communication Cadence That Healthy Partnerships Use

A healthy agency relationship should have a regular communication schedule.

You should know when updates will be shared, what each meeting is meant to cover, who needs to attend, and which urgent issues should be reported immediately.

The weekly update does not always need to be a long meeting.

For many accounts, a short written update works better because it creates a clear record of problems, decisions, and things the agency is waiting for.

Monthly reviews should focus on performance and explain what happened.

The quarterly business review, or QBR, should look at the bigger picture. It should question the current strategy and decide what needs to change next.

Silence is a warning sign.

If you mainly hear from your agency when a report is due, when the contract renewal is coming, or when you ask them for an update, the relationship is too reactive.

Good account management means the agency should warn you early when inventory, pricing, compliance, creative, or advertising problems could affect the plan.

Who Owns What: The Client-vs-Agency Division of Labor

Many agency relationships fail because responsibilities are unclear.

The client thinks the agency is handling something, while the agency thinks it is waiting for the client.

You can avoid this problem by clearly deciding who owns each responsibility based on the signed scope of work.

Use this as a RACI-style starting point, not as a rule that applies to every agency relationship.

If you hire an agency only for PPC, your internal team will probably own more responsibilities.

If you hire a full-service agency, the agency may handle more of the execution.

However, the client still owns internal approvals, legal decisions, financial commitments, and important business information that only the internal team can provide.

This table focuses on the bigger relationship between the client and agency. For daily account work, use a separate guide that explains what your account manager should check every day.

Reading the Reports: Real Progress vs Vanity Metrics

Agency reports should show whether your business is moving in the right direction and explain why results changed.

A report that only lists completed tasks can look impressive without proving that the work actually helped the business.

You need explanations, tradeoffs, and decisions, not just a list of things the agency worked on.

• TACoS trend: Is advertising becoming more or less efficient compared with total sales? What is causing the change?
• Contribution margin: Are your growth decisions helping the business stay profitable after important costs are included?
• Organic rank: Are your important products gaining or losing visibility for valuable search terms and categories?
• New-to-brand (NTB): For supported Amazon Ads formats, are your campaigns reaching customers who are new to your brand? See Amazon Ads’ official new-to-brand metrics documentation for the current definition and availability.

Impressions, clicks, raw ACoS, and the number of campaigns that were “optimized” can still be useful.

However, these numbers do not tell the full story by themselves.

Ask what each number means for the business, how it compares with the agreed starting point, and what the agency plans to do next because of the result.

Questions to Ask in Every Agency Review

• What changed since the last review, and what is the strongest evidence showing why it changed?
• Which result is not going according to plan, and what are you doing about it?
• What decision or information do you need from us before the next review?
• Where are we giving up some growth to protect margin, or giving up some margin to increase growth? Is that still the right decision?
• What is the biggest risk you see in the next 30 to 90 days that we may not be watching?

These questions move the discussion beyond basic task reporting.

A capable agency should be able to explain its strategy in simple language, clearly explain the tradeoffs, and tell you when a problem is outside its responsibility instead of hiding behind a dashboard.

Warning Signs It’s Time to Switch

One bad month does not automatically mean you should fire your Amazon agency.

A bigger warning sign is when the same problems continue again and again, such as poor communication, weak ownership, bad decisions, low transparency, or no improvement after problems have already been discussed.

Judge the agency over several review periods and compare its performance with the services you actually hired it to provide.

• Reports look generic and do not connect results to your business goals.
• The agency rarely identifies problems before your internal team finds them.
• The team cannot clearly explain why it is using its current strategy or what would make it change that strategy.
• Communication becomes quiet between reporting dates or suddenly increases when contract renewal is close.
• Advertising spend keeps increasing, but profit or total business efficiency does not improve according to the agreed plan.
• The team does not have enough ex-Amazon or similar marketplace experience to handle the problems your account is facing.
• Your own team found the last three major account problems even though you are paying the agency for proactive management.

Before ending the relationship, first decide whether the problem can be fixed or whether the agency simply does not have the right skills.

Reset your goals, clearly explain the scope again, document responsibilities that were missed, and create a short recovery plan with clear deadlines.

Also review your agency contracts and red flags so you understand notice periods, ownership of data, account access, and transition requirements. You do not need to renegotiate the entire pricing model during a performance discussion.

If the problems continue and the recovery plan does not work, prepare the handoff before removing the agency’s access.

Export important reports and working files. Document tests that are currently running. Record unresolved support cases and compliance problems. List recurring tasks and agree on the final transition date.

If you need another partner, use a separate framework for choosing an Amazon agency instead of rushing to find a new agency during the offboarding process.

Once you have a shortlist, use a separate resource for comparing agencies.

Keep the diagnosis and the new agency decision separate. First, confirm that your current relationship is failing because of problems that another agency can realistically solve.

Frequently Asked Questions about How to Manage your Amazon Agency

How do I get the most out of my Amazon agency?

Give your agency clear goals, the right account access, margin information, quick approvals, and regular performance reviews.

Judge the agency based on the business results you agreed on, not simply by how many tasks it completes.

Your own team also plays an important role. Slow decisions, missing information, and unclear responsibilities can make it difficult for even a good agency to perform well.

What should I give my Amazon agency during onboarding?

Give the agency the correct account access, margin or COGS targets, historical performance data, brand guidelines, known account problems, and your main success metric.

You should also clearly identify who inside your company can make important decisions.

The goal is to stop the agency from wasting paid onboarding time asking for information your team already has.

How often should my Amazon agency report to me?

A good starting point is weekly updates for problems and decisions, monthly performance reviews, and a quarterly business review for bigger strategic decisions.

The exact schedule can change depending on the size and complexity of your account.

Urgent inventory, compliance, pricing, or advertising problems should be reported as soon as they happen instead of waiting for the next scheduled meeting.

What should an Amazon agency be responsible for vs me?

Responsibilities should follow the services listed in your signed contract.

Agencies often handle execution such as advertising optimization, listing work, monitoring, analysis, and recommendations.

Clients normally control major business decisions such as total budgets, final pricing, approvals, compliance documents, purchasing, and legal decisions.

Write these responsibilities down clearly so neither side assumes the other side is handling something.

What metrics should I hold my Amazon agency accountable to?

Choose two or three metrics that directly connect to the reason you hired the agency.

Depending on your business, these may include contribution margin, TACoS, organic rank, or new-to-brand performance.

Do not judge the agency only by impressions, raw ACoS, or how many campaigns it changed during the month.

What are signs my Amazon agency isn’t working?

Look for problems that keep happening.

These can include generic reports, weak explanations, poor proactive communication, important problems being found by your team first, slow responses, and increased spending without the agreed business results.

One bad month alone is usually not enough to make a decision.

Compare the agency’s performance with the agreed scope, goals, starting point, and any recovery steps you have already discussed.

When should I switch Amazon agencies?

Think about switching when the same skill, performance, or accountability problems continue even after you create a clear recovery plan.

First, document the problem, explain the scope again, set clear deadlines, and give the agency a fair chance to fix it.

If the problem continues, prepare your data, account access, active tests, unresolved cases, and transition responsibilities before ending the partnership.

What is a QBR and do I need one with my agency?

A QBR is a quarterly business review.

It focuses on bigger strategy decisions instead of daily or weekly tasks.

A QBR should review major performance trends, category changes, risks, priorities, and resources needed for the next quarter.

Most long-term agency relationships benefit from having one because it gives both sides a regular time to question the current strategy and change direction when needed.

How do I know if my agency’s reporting is just vanity metrics?

Ask whether each metric helps you make a business decision.

Impressions, clicks, activity counts, and raw ACoS can be useful, but they need context.

Good reporting connects metrics to your goals, explains why performance changed, shows important tradeoffs, and clearly explains what will happen next.

A list of completed tasks without business explanation is not a proper performance review.

How much access should I give my Amazon agency?

Give the agency only the access it needs to complete the work included in the contract.

Do not give broader permissions simply because it is easier.

Keep a record of who has account access and make sure you continue to own your main account and business records.

Review permissions whenever the agency’s responsibilities change, a team member leaves, or your relationship with the agency ends.
