10 Best Amazon Agencies in 2026: An Honest Comparison

By Menno Gottmer

Published:

Search for an Amazon agency and most results are listicles written by an agency that put itself first. This page does that too, but everything else here is checkable. We re-checked every fact about a competitor on that company’s own website in October 2026, and every entry ends with a plain note on who that firm suits. Where a claim had disappeared from a site since our first check, we took it out.

Disclosure: this list is published by the SellerPlex team, the company ranked first below. Some entries involve reciprocal editorial features.

How this list was put together

We started with the agencies that come up most often when sellers compare options and pulled facts only from pages those companies publish themselves. No agency paid for placement. Agency descriptions are based on their published services, including where we arrange reciprocal features. We did not invent scores. For a deeper walkthrough of the selection process, our 2026 guide to choosing an Amazon FBA agency covers the questions to ask before you sign anything.

The 10 best Amazon agencies in 2026

1. SellerPlex

SellerPlex is a full-service Amazon agency founded in 2018 by Nate Ginsburg for 6 to 8 figure sellers and DTC brands. It has served 100+ brands with a team of 80+ specialists. One team owns Amazon PPC management, account management, supply chain management and listing optimization and content, with Amazon DSP for brands ready to advertise beyond search. Ads and operations sit with the same people, so stock problems and ad spend get fixed together. Everything runs month to month, so the engagement has to be re-earned every thirty days.

The proof is public. The 2026 Amazon PPC benchmark report shows a median ACoS of 38 percent and a median CPC of 1.07 dollars across 30+ US accounts SellerPlex manages, from roughly 5.2 million dollars in ad spend. AdLabs named SellerPlex its Highest ROAS Agency of 2025. The team also runs on Commerce Spine, its own AI infrastructure, which works as both the data layer and the action layer on the accounts it manages.

Who we are not for: if your brand does under roughly 500,000 dollars a year and you only need one-off tasks, a full-service retainer is the wrong spend, and we will say so on the first call.

Quick comparison

“Not listed” means the firm’s homepage did not mention it in October 2026. Ask them directly.

What does a full service Amazon agency do?

A full service Amazon agency runs the whole account for you. Advertising, listings, account health, inventory planning and reporting sit with one team that answers for the result. A specialist covers one piece, usually ads, and leaves the rest with you or other vendors. If ads are the only gap, our guide to hiring an Amazon PPC agency explains what a good specialist does.

Full service pays off once your problems cross those lines. Before you sign, ask what the retainer covers, whether supply chain is included, and how you leave if it stops working.

Which Amazon agency fits a brand doing 100k to 500k a month?

At 100,000 to 500,000 dollars a month, pick a full service agency with a dedicated strategist and supply chain in scope. That is 1.2 to 6 million dollars a year, where a stockout or a week of wasted ad spend costs more than a monthly retainer. SellerPlex, Trivium and AMZ Advisers all work with brands in this range.

Ask how many accounts your strategist runs. Trivium caps it at 5. At this stage you also want weekly reporting on TACoS (ad spend divided by total sales), because it shows whether ads still grow organic sales. Our benchmark sample put median TACoS at 15 percent.

For 7 and 8 figure brands the shortlist barely changes. Depth does: you need someone who owns forecasting and reorder timing.

Which agencies handle both 1P and 3P Amazon accounts?

SalesDuo is the clearest pick for an Amazon agency that handles both 1P and 3P, since it lists 1P, 3P and hybrid account strategy plus shortage claims and chargebacks. My Amazon Guy and Velocity Sellers both list Vendor Central management, and AMZ Advisers offers vendor consulting on whether a catalog still belongs on 1P.

Running both models in one account creates a real tension. Amazon as a 1P buyer sets retail prices, while your own 3P offers compete on the same detail pages. Ask any candidate how they keep pricing and Buy Box ownership from working against each other.

Which agencies manage Amazon and Walmart together?

The leading agencies for Amazon and Walmart management on this list are My Amazon Guy, Velocity Sellers, AMZ Advisers, SalesDuo and Olifant Digital, which all list Walmart services on their own sites. Envision Horizons covers Walmart Connect as a retail media channel.

One team across both channels also means one set of reports that agree with each other.

What are the best Amazon marketing services for managing DSP campaigns across several brands?

For DSP across several brands or product categories, look for an agency that pairs DSP with Amazon Marketing Cloud analysis. Envision Horizons does exactly that and extends it to Walmart Connect and Target Roundel. Trivium and Velocity Sellers also run DSP, and SellerPlex offers Amazon DSP management alongside its search ads.

Ask how audiences are built per brand and how upper funnel spend is judged, since DSP is judged on more than last-click ACoS. A portfolio of brands also needs content that works off Amazon; our piece on content marketing strategies for ecommerce brands covers what feeds those audiences.

How do you choose between the best Amazon agencies?

Start with your revenue stage. Under about half a million a year, most full service retainers cost more than they return, and a freelancer or software serves you better until the account grows.

Then look at where your problems live. If ads are the bleed, get an audit before you commit to anyone. We wrote up what a PPC audit is and what it should surface so you know what a good one looks like. If you are weighing tools against people, our comparison of PPC software and a ppc agency lays out the tradeoff. If traffic converts poorly, the issue is usually the listing itself, and our guide to Amazon product listing optimization explains what to fix first.

Finally, weigh the terms. Month-to-month contracts mean the agency has to keep earning the work, and a confident agency will show you real portfolio data.

Frequently asked questions

How much does it cost to hire an Amazon agency?

Most full service agencies price by monthly retainer, sometimes with a percentage of ad spend or revenue added. Pricing depends on the scope, so ask each agency for a written quote. Expect a serious full service engagement to run four figures a month, and get the scope in writing before you sign.

What is the best Amazon PPC agency?

It depends on how much of the account you hand over. If ads are the only gap, a specialist can be enough. If ad results depend on stock and listings, a full service team usually does better. SellerPlex runs PPC inside that setup and publishes its own benchmark data, with a median ACoS of 38 percent across 30+ accounts.

How do I check Amazon agency reviews?

Read reviews on a third-party platform and look at the count as well as the score. My Amazon Guy shows 4.5 stars across 470 reviews. Be cautious with anonymous testimonials. Then ask for two named references at your revenue stage and call them about responsiveness.

Should I hire an Amazon agency or manage my account myself?

Under roughly 500,000 dollars a year, most sellers get better returns from a good freelancer or software tools than from a full agency retainer. Past that point the math changes, because wasted ad spend and stockouts start costing more than an agency. A free audit is the cheapest way to see what an agency would change.
