Best for: Brands selling on Amazon that are based in California and want one team running listings, advertising, and brand protection instead of three freelancers who never talk to each other. This fits brands that own their products and sellers who distribute other brands across Los Angeles, San Diego, and the Bay Area, typically doing $25,000 to $2M+ per month on Seller Central or Vendor Central. Beauty, apparel, supplements, and tech or DTC brands fit best, including established brands launching new catalogs on Amazon.com.
An Amazon agency in California manages the work that decides whether your account makes money: listings, advertising, inventory, and account health. At Desverto we work as a full-service Amazon agency and take that work off your team. We write and optimize your listings, run your Sponsored Products and Sponsored Brands campaigns, plan stock around Prime Day and the Q4 holiday peak, keep you compliant with California rules, and keep the account healthy enough to keep selling. You approve the strategy, and you see every change before it goes live.
How we do it matters as much as what we do. We fix the listing and its Featured Offer eligibility before spending on traffic, because Amazon will not show your Sponsored Products ads on a listing that cannot win the Featured Offer. We model your fees before setting an ad budget, so every campaign has a profit target and an ACoS target. That order comes from seven years in the Amazon ecosystem and more than 3,500 optimized listings. Spending first and fixing later is the most expensive habit we see in new accounts.
The value for you is an account you can actually read: what you sold, what Amazon took, what the ads cost, and what was left. When a California brand moves to us from an agency that only ran ads, we usually find the same three things. Strong campaigns pointed at weak listings. Nobody has modeled the real fee stack. Brand Registry was never set up. We manage all of it under one plan with one monthly report, and the account stays in your name throughout.
Amazon accounts rarely fail because of one big mistake. They stall because of small setup and reporting gaps that compound every month. A listing that loses the Featured Offer stops showing its ads. A margin model built on the referral fee alone hides a large part of the real cost. None of it shows up in a sales dashboard, which is why an agency that only watches the ads will miss most of it.
Here is where those gaps usually start:
Sponsored Products ads do not display on a listing that is not eligible for the Featured Offer. Price, stock, and account health decide that eligibility, so an agency that adjusts bids before checking them is tuning ads that are not even serving.
Referral fees on most categories are 15%, with some lower and a few far higher, per Amazon’s US fee schedule. Then comes the FBA fulfillment fee, monthly storage that jumps in the October to December peak, and newer charges like the low-inventory-level fee and inbound placement service fee. The real per-unit cost rarely matches the launch spreadsheet.
A 3.5% fuel and logistics surcharge took effect on April 17, 2026, and the inbound placement service fee took effect on January 15, 2026. Accounts still working off a 2024 margin model are quietly losing a few points per unit they never accounted for.
California requires a Prop 65 warning on products that expose consumers to listed chemicals, and Amazon collects that warning information in Seller Central. A missing or wrong warning can get a listing suppressed or expose the brand to an enforcement claim.
California sells into visually competitive categories on the platform: beauty, apparel, and supplements. A listing that looks homemade next to a polished competitor loses the click before copy or price ever enters the decision, and no amount of bid tuning fixes that.
A+ Content, Brand Stores, Sponsored Brands, and Amazon’s brand-protection tools require Brand Registry, which needs a pending or registered trademark. Enroll after launch and you sell the early months without the content and protection that lift conversion.
Suppressed listings, compliance flags, and restricted-category issues get ignored while everyone watches the ad dashboard, then turn into a suspension that stops sales entirely. Supplement and skincare brands carry the most exposure here.
Some engagements still run on a shared password. That gives the agency more control over your account than you have, and it makes switching painful. Seller Central has user permissions built in for exactly this reason.
Very few agencies publish a price range. Without one, you cannot tell whether a proposal is fair until you have already put hours into the sales process.
Stock has to reach the fulfillment center well before Prime Day and Q4. Storage costs rise during the holiday peak, so a plan that looks profitable in spring can lose margin when inventory arrives late or sits too long.
Sales and ROAS alone do not show what remains after Amazon fees, product costs, freight and ads. Without contribution margin and TACoS, an account can look busy while losing money.
Every account we take on gets scored across three layers before we change a bid or rewrite a title. The layers are the same in every market we work in. What we measure inside them is specific to a US account selling out of California.
Featured Offer eligibility first, then ACoS, TACoS, CPC, and conversion rate by campaign. This is the layer most agencies report because it updates daily and looks good in a report. It is also the one that tells you the least on its own.
Contribution margin after the referral fee, FBA fee, storage, aged-inventory and low-inventory surcharges, the 2026 fuel and logistics surcharge, ad spend, and cost of goods. This is where most accounts look different from what the owner expected. A product with a strong sales rank can still lose money once fees come out of every unit.
Brand Registry status, California compliance including Proposition 65, organic rank movement, and in-stock rate going into Prime Day and Q4. This layer decides whether next year’s sales still need this year’s ad budget to hold.
Most agencies stop at Layer 1. We report all three. Layer 1 on its own cannot tell you whether a better month came from a healthier account or from spending more.
An account plan built from your audit, your fee stack, and your catalog. Not a template with the state name swapped in.
Every engagement includes:
We review the full strategy every quarter and again before each major sales event. Q4 and Prime Day stock has to reach the fulfillment center well before the event starts, and a monthly bid review will not catch that in time.
Our Amazon account management covers the work inside Seller Central, end to end. The first two weeks are an audit of your listings, ad structure, fee stack, Brand Registry status, California compliance, and peak-season readiness, and the plan comes out of that. Freight, tax filing, and business licensing stay with your forwarder, accountant, and attorney. We coordinate with them so nothing stalls between teams.
Listing optimization starts with keyword research, then titles, bullets, backend search terms, and A+ Content written around how people actually search. The listing images, A+ modules, and storefront are built to convert in visually competitive California categories, not just to look finished. The listing gets fixed before we buy traffic for it.
Sponsored Products, Sponsored Brands, and Sponsored Display, structured around branded, non-branded, competitor, and defensive targeting. Budgets follow contribution margin, and search-term harvesting runs every week. For new sellers, Amazon’s advertising credits go into keyword discovery, where they show which terms convert before real budget goes in.
Brand Registry enrollment (through Amazon’s IP Accelerator if you do not have a trademark yet), Brand Store setup, Proposition 65 and category-compliance review, account-health monitoring, and launch planning for new ASINs and peak events. The California compliance work is the part out-of-state agencies most often leave out.
A quick illustration of why Layer 2 matters. Before: $16,000 a month in ad spend on $89,000 of sales at a 32% ACoS, reported as progress because it was 36% the month before. Nobody had priced the 15% referral fee and the FBA fee into the plan, and together they take roughly $24 out of every $89 unit. After: the same budget, with broad terms that never converted cut, spend moved to the exact terms that do convert, and stock planned ahead of Q4. ACoS rises slightly to 34%, but sales reach $110,000, TACoS falls from about 18% to 14.5%, and monthly profit after fees, ads, and product cost goes up by roughly $8,300. These are worked numbers to show the math, not a client case. Your audit uses yours.
Search for Amazon agency pricing and you will find very little published, because almost nobody puts a number on the page. Here is what the US market looks like, based on the ranges that are public.
Full-service management generally runs from about $2,000 a month for a smaller catalog to $10,000 or more for a large one, with established brands doing several million a year often landing between $5,000 and $12,000. PPC-only management is usually a flat fee of roughly $1,500 to $8,000 a month, or 10 to 20 percent of ad spend, often with a monthly minimum around $1,500 to $2,500. Some agencies use a hybrid, with a lower base fee plus a performance component tied to a TACoS target.
The model matters as much as the number. A percentage of ad spend pays the agency more when you spend more, whether or not that spend is profitable. A flat retainer removes that pull but does not reward results either. We price each engagement after the audit, based on SKU count, ad spend, and scope, and we tell you which model fits before you sign. You keep ownership of the account and everything we create, and you can leave with a full handover.
Amazon’s shopping assistant now reads a different data layer than keyword rank: your backend attributes, your copy, your Q&A, and your reviews feed what gets recommended in conversational search across more and more surfaces. A listing built only for a 2020-era search box hands that AI layer almost nothing to work with.
At the same time, the 2026 fee changes have squeezed margins, so the accounts that win are the ones measuring profit per unit, not just ACoS. For a California brand in a visually competitive category, the move is the same either way: budget toward creative that converts and listings an AI can read, and away from more spend on pages that were never built to convert. An agency still selling ads-first, creative-later has the order backwards.
It runs your Amazon account as one plan: listing optimization, advertising, inventory, Brand Registry, and account health, measured against your margin rather than ad efficiency alone. A good one also handles California-specific compliance like Proposition 65. The account stays in your name, and you approve the work before it goes live.
Full-service management generally runs from about $2,000 to $10,000 or more per month depending on catalog size, and PPC-only management is often $1,500 to $8,000 a month or 10 to 20 percent of ad spend. We price after the audit, based on SKU count, ad spend, and scope, so you see the model and the number before you commit.
No. Amazon work is done remotely, so competence and category experience matter more than a local address. What does matter is verifying who actually runs your account and whether they handle California compliance, because several agencies that rank for this search are based out of state or offshore behind a California page.
If your products expose California consumers to any listed chemical, yes. Amazon collects Prop 65 warning information in Seller Central, and a missing or incorrect warning can get a listing suppressed or draw an enforcement claim. We review your catalog for it as part of the audit.
Beauty and K-beauty, apparel and fashion, supplements and wellness, and tech or DTC lifestyle brands dominate the state, spread across Los Angeles, San Diego, and the Bay Area. Each demands something specific, from ingredient-led visuals for beauty to compliant claims for supplements. An agency that has worked in your category moves faster and makes fewer mistakes.
Both. We run listings, creative, advertising, and account management as one stack, sequenced so ads scale traffic to a page that is already built to convert. You can also hire us for listing or PPC work on its own if that is all you need right now.
You do. We work through Seller Central user permissions, never a shared password, and every listing, image, and A+ module we create belongs to you. If you leave, you get a full handover.
Fixing Featured Offer eligibility and wasted ad spend usually shows within the first month. Listing and keyword changes take four to eight weeks to show in organic rank. A turnaround where TACoS and contribution margin both improve typically takes around three months, longer if the account needs Brand Registry or a compliance fix first.
An account engagement works best when the listings underneath it already convert. These services are often added before or alongside it:
Custom images per SKU, chosen by category behavior and the questions a shopper has before they buy.
Image-and-text modules that replace the plain description. Premium A+ adds full-width layouts, interactive modules, and video.
Backend and copy structured so Amazon’s AI assistant can recommend your product in conversational search.
