Seller Central is the web console through which independent merchants sell on Amazon's stores. From one login at sellercentral.amazon.com or a national equivalent, a business lists products against Amazon's catalogue, sets its own prices, chooses whether to ship orders itself or hand the stock to Amazon, buys advertising and collects its payouts. The console exists because Amazon runs two retail models side by side. In one, Amazon buys goods wholesale and resells them. In the other, outside sellers keep ownership of the stock and pay Amazon fees. Seller Central runs the second model, which accounted for 61% of paid units sold on Amazon worldwide in the second quarter of 2026, according to Amazon.

How the console works

Access starts with verification. Applicants upload a government-issued identity document and proof of address dated within 180 days, then photograph their face alongside the document or join a video call with an Amazon associate, according to Amazon's registration guide.

Two selling plans set the price of entry. The Individual plan costs $0.99 per item sold; the Professional plan costs $39.99 a month, according to Amazon's US pricing page as of September 2026, so the arithmetic crosses at roughly 40 units a month. Only Professional accounts get bulk listing, automated pricing, business-to-business and global selling, application programming interfaces (APIs) and Amazon Ads.

On top sits the referral fee, Amazon's commission on each sale: a percentage of the total price or a fixed minimum, whichever is greater. Most US categories pay 15%. The schedule runs from 3%, on the part of a watch's price above $1,500, to 45% on Amazon device accessories, with a $0.30 minimum in most categories and a $1.80 closing fee on media such as books. The minimum bites at low prices. A $2.50 baby product in the 8% band would owe $0.20 but pays $0.30, an effective 12%.

Listing is catalogue-first. A seller enters a product identifier such as a UPC or EAN barcode number, and Amazon attaches the offer to an existing Amazon Standard Identification Number (ASIN) or creates one; the same catalogue is exposed to software through the Catalog Items API. Several sellers can offer one ASIN, competing for the Featured Offer on its page.

Fulfilment is a switch on each listing. Fulfilled by Merchant (FBM) orders are shipped by the seller, while Fulfillment by Amazon (FBA) stock travels to Amazon's warehouses through inbound shipment plans built in the console. The Account Health dashboard tracks Order Defect Rate, Late Shipment Rate, Cancellation Rate and On-Time Delivery Rate. Since August 31, 2026, a US merchant-fulfilled offer that breaches those thresholds is switched off on its own rather than the whole account being penalised.

Money moves on Amazon's schedule. Under a reserve rule known as DD+7, proceeds become available seven days after confirmed delivery: in Amazon's example, an order sold on January 1 and delivered on January 3 is released on January 11. Accounts still on older settings were moved across on March 12, 2026.

The console doubles as Amazon's noticeboard, carrying policy notices in a Seller News panel and on its forums, and as a promotions desk, with Lightning Deals created under Advertising, then Deals.

Large sellers rarely work screen by screen. The Selling Partner API (SP-API) lets repricers, inventory tools and agencies read and write account data, and its Appstore listed more than 2,500 applications serving over 1.4 million sellers in May 2026. One counterparty writes the rules, runs the catalogue, sets the fees and settles the disputes.

From zShops to one console

Amazon opened to outside sellers in 1999 with Amazon Auctions and zShops, then launched Marketplace in November 2000, placing third-party offers beside its own. Fulfillment by Amazon followed on September 19, 2006. A British order management software supplier dated Amazon's new merchant platform, "also known as Seller Central", to November 2006, with existing merchants moved across gradually. Amazon has published no launch date of its own.

Automation came next. Marketplace Web Service (MWS), introduced in 2009, let developers exchange listing, order and report data with accounts. Sponsored Products, commonly dated to 2012, put advertising inside the console, and Brand Registry, launched in 2017, tied listing control, and later several ad products, to trademark ownership.

In October 2020 Amazon announced SP-API, a REST (representational state transfer) interface using JSON data and OAuth 2.0 authorisation; MWS stopped working after March 31, 2024. Regulators reshaped the terms in parallel. The European Commission made Amazon's commitments binding on December 20, 2022, including a pledge not to use sellers' non-public data in its retail business, and the Federal Trade Commission (FTC) and 17 states sued Amazon on September 26, 2023.

Then Amazon began automating the console itself. On September 17, 2025, Seller Assistant gained agentic capabilities, monitoring accounts, managing inventory and running advertising with seller approval.

Why it matters for marketers

For brands selling as third parties, Seller Central is where retail media budgets originate. Sponsored Products, Sponsored Brands and deals are bought against listings managed there, and several ad products require Brand Registry, a gate that filters out resellers. Media and margin increasingly draw on one balance. In April 2026 Amazon told a subset of US sellers that advertising costs would be deducted from their retail proceeds instead of billed to credit cards, then pushed the change back to August 1. When a 3.5% fuel surcharge on fulfilment fees arrived that month, Million Dollar Sellers, a group of more than 700 merchants, responded with a 24-hour advertising boycott.

Scale explains the attention. Third-party seller services revenue, mostly commissions and fulfilment fees, reached $46.8 billion in the second quarter of 2026, up 16%, while advertising services added $19.8 billion, up 26%, according to Amazon. EcomCrew, an e-commerce publisher, estimated that revenue per third-party unit rose only about 1%, so volume drove most of the fee growth. Amazon also says more than 75,000 independent sellers passed $1 million in sales in 2025, up 36%, and that Seller Assistant drew more than 230,000 monthly users.

Limitations and disputes

Cost is the central complaint. Once per-sale charges and advertising are combined, many sellers pay close to half of their total revenue to Amazon, according to the FTC's 2023 antitrust complaint. The Institute for Local Self-Reliance put Amazon's cut at 45% in the first half of 2023, Marketplace Pulse figures reported by Fortune put it near 50% in 2022, and the gap turns largely on whether advertising counts as a fee at all. Amazon denies the allegations. Trial is due in Seattle in 2027, on March 29 according to MLex, though some published accounts cite February.

Advertising pricing is a separate front. A complaint filed on August 31, 2026 by the FTC and 22 states alleges an undisclosed soft reserve in Amazon's sponsored ads auction. Amazon disputes it, saying inflation-adjusted cost per click for Sponsored Products was flat from 2019 to 2024 while conversion rates rose more than 24%.

Price control is another. Germany's Bundeskartellamt prohibited Amazon's algorithmic price caps on February 5, 2026and ordered disgorgement of about 59 million euros. "Amazon directly competes with the other Marketplace sellers on its platform," said Andreas Mundt, the authority's president.

Enforcement draws complaints too. One UK merchant's account was suspended three days after Amazon reinstated the disputed listing, following two weeks of fake orders. Seller Challenge allows three escalations per six months with a 48-hour review, but only for members of the Account Health Assurance programme.

Data is contested in both directions. Amazon's Business Solutions Agreement update of March 4, 2026 requires outside AI agents to identify themselves and stop on request, and SP-API fees of $1,400 a year plus usage charges were withdrawn in May 2026 after developer pushback. Inbound data raises an older worry. In 2020 The Wall Street Journal reported that Amazon staff had used independent seller data to develop house-brand products, according to GeekWire; Amazon said it bars such use of non-public, seller-specific data.

Not to be confused with

Vendor Central is the invitation-only portal for first-party (1P) suppliers that sell wholesale to Amazon, which then sets the retail price. Brands using both portals are called hybrid.

Amazon Ads console is where campaigns are managed. Sellers reach it through Seller Central, but vendors, agencies and advertisers with nothing sold on Amazon use it directly.

Seller Center, a near-namesake, names the merchant back ends of Walmart Marketplace and TikTok Shop.

Seller, in programmatic advertising, means a publisher or intermediary listed in a sellers.json file.

Recent developments

Amazon used its Accelerate seller conference to recast the console. On September 23, 2026, it launched a Selling Partner plugin, in beta in the US, letting sellers check inventory, change prices and edit listings from Amazon Quick or Anthropic's Claude. "Our vision was that they would never have to log into Seller Central," Mary Beth Westmoreland, Amazon's vice president of Worldwide Selling Partner Experience, told GeekWire.

A day later came multichannel selling tools, free and rolling out gradually in the US, which bring eBay, Shopify, TikTok Shop and Walmart listings and orders inside Seller Central. Westmoreland said the off-Amazon data is "never used for anything other than surfacing it to that specific seller". Yet 71% of Amazon-primary sellers active on another marketplace still earn at least three-quarters of their marketplace revenue from Amazon, according to Marketplace Pulse's 2026 Seller Index.

Obligations keep arriving through the same screens. From November 2, 2026, US sellers in safety categories such as children's products and cosmetics need $1 million of liability insurance whatever their sales, and from January 11, 2027 most single-ASIN bundles must be packaged by the original manufacturer or brand.

Summary

Who: Amazon, which builds and runs Seller Central and sets its fees and rules; the independent merchants, brands and agencies that operate accounts, including more than 75,000 sellers that passed $1 million in 2025; software developers connecting through SP-API; and regulators such as the FTC, the European Commission and Germany's Bundeskartellamt that contest its terms.

What: Amazon's web console for third-party selling, covering registration, listings, pricing, fulfilment, account health, payouts, promotions and advertising, with fees made up of a selling plan charge, a referral fee of mostly 8% to 15% and optional services.

When: Outside selling began with zShops in 1999 and Marketplace in 2000; the platform known as Seller Central dates from around 2006. Its API was rebuilt from 2020, its assistant became agentic in September 2025, and in September 2026 Amazon opened it to rival marketplaces and outside AI assistants.

Where: At sellercentral.amazon.com and national equivalents across Amazon's stores, with several 2026 changes, including DD+7 migration, offer-level enforcement and multichannel tools, applied first or only in the US.

Why: Third-party sellers supply most of the units Amazon sells, and the seller services billed through the console generated $46.8 billion in the second quarter of 2026 alone. Control of that interface decides what sellers pay, what they see and which rules apply, which is why it sits at the centre of antitrust cases on both sides of the Atlantic.
