If you've ever Googled "Amazon agency" and come back more confused than when you started, you're not alone. The category includes everyone from boutique specialists who've managed a handful of brands to large performance shops running nine-figure ad spend. The services they offer, the pricing models they use, and the way they actually work with clients vary quite a bit. So here's a plain-English breakdown of what an Amazon agency actually does and when you might need one.
The Core Services
Most Amazon agencies fall into one of two buckets: full-service account management and point-solution specialists. Full-service agencies handle all the major functions of an Amazon account: catalog management, advertising, content, inventory strategy, and account health. Point-solution agencies focus on one thing, usually PPC or creative, and do it well. Neither model is better in the abstract; it depends on what your business actually needs.
A full-service agency typically covers account setup and ongoing management (opening brand registry, catalog architecture, variation strategy), advertising (Sponsored Products, Sponsored Brands, Sponsored Display, DSP), content (listing copy, A+ content, storefront), and operational support (FBA shipment management, replenishment planning, case management). Some agencies also offer strategic guidance on pricing, competitive positioning, and channel mix. The scope varies, so when you're evaluating agencies, it's worth asking specifically what's included and what's billed separately.
What Good Account Management Actually Looks Like
The day-to-day work of Amazon account management is less glamorous than most agencies make it sound on their websites. It's catalog audits, Buy Box monitoring, suppressed listing fixes, stranded inventory cleanup, and weekly reporting. It's managing the cadence of FBA inbound shipments so you don't go out of stock the week before Prime Day. It's opening support cases to correct data errors that Amazon's systems introduce without warning, then following up on those cases because the first response is often wrong.
On the advertising side, good management means more than adjusting bids weekly. It includes building the right campaign structure from the start, managing keyword harvest from auto campaigns, running A/B tests on creative, and understanding how ad performance interacts with organic rank. A lot of brands find that their agency optimizes ad metrics without ever asking whether the overall strategy is right. Those are different problems.
Content is the third pillar, and it's increasingly important. Alexa for Shopping, Amazon's AI shopping assistant, pulls from listing content and A+ modules to answer shopper questions. If your title, bullet points, and A+ content aren't written for how AI surfaces answers, you're at a structural disadvantage, not just an SEO one. Our content optimization for AI search work is designed specifically for this shift.
Pricing Models and What They Mean in Practice
Amazon agencies generally price in one of three ways: flat monthly retainer, percentage of ad spend, or a hybrid of both. Flat retainers are predictable for budgeting and align the agency's incentive with account health broadly, not just ad volume. Percentage of ad spend is common for advertising-only engagements and tends to scale with your media budget. The hybrid model is a retainer plus an ad spend percentage, which is how most full-service shops structure things at scale.
What you want to avoid is a pure commission model tied to revenue. It sounds performance-driven, but it creates misaligned incentives: the agency benefits from your baseline business, not just from the incremental value they create. If your brand would generate $2M on Amazon with no agency at all, a 5% commission means you're paying $100,000 a year for whatever marginal improvement they contribute. That's a hard number to justify, so take a look at our pricing page for a full breakdown of how agency pricing actually works.
When You Actually Need an Agency
The honest answer is that not every brand needs an agency. If you have a small catalog, steady sales, and someone on your team who can manage the account competently, you might be fine on your own. Amazon's tools have gotten better, and a focused in-house operator can handle a lot. DIY Amazon Seller Central management tools like CentralDesk can automate a lot of the routine processes and surface insights that would otherwise take hours in spreadsheets, which changes the math on whether you need outside help.
The calculus changes when your catalog grows, when advertising gets complex enough that campaign structure and bid logic require real expertise, when account health issues start taking meaningful time to manage, or when you're entering a new category or marketplace that you don't know well. It also changes when you're leaving money on the table and you're not sure why: whether that's a content problem, a bidding problem, or a listing suppression you didn't notice.
The best way to find out whether an agency would make a difference for your brand is to walk through your account with someone who's seen a lot of them.
