E-commerce
April 8, 2026
We often hear “the Amazon e-commerce platform” used to refer both to the consumer-facing retail site, the seller account, and sometimes other services of the group (cloud, streaming). This guide clarifies what the term covers for an e-commerce merchant: in practice, it mainly refers to Amazon’s marketplace, accessible via Seller Central, and the associated programs (shipping, advertising, brand), not a tool equivalent to a Shopify store that you host on your own domain.
For the generic marketplace / online commerce distinction: see e-commerce and marketplace: same thing? and how an e-commerce business works. Returns and logistics are detailed in the dedicated sections below.
Official seller sources: the public documentation for selling in Europe is presented on sell.amazon.fr (sign-up, guides, pricing); the day-to-day management interface is Seller Central. Subscription amounts, fees, and promotions change: always check the Pricing and Help pages when you read this article.
We do not assign quantified “global” market shares here: they depend on definitions and sources. However, the official seller FAQ indicates that small and medium-sized businesses account for more than half of units sold in Amazon stores worldwide (wording taken from the FAQ on sell.amazon.fr, section “Is Amazon right for my business?”).
At Qstomy: our core business is the online store you control (often via Shopify) and AI-assisted support / sales; Amazon remains a channel in its own right with its own rules, often complementary to a D2C model (see the complementarity section).
In short: “Amazon platform” mainly refers to Amazon’s third-party selling ecosystem (interface, rules, programs), not an autonomous CMS like an independent store.
Buyers often see a single interface (search, cart, Prime payment); sellers see a pricing grid, quotas, and policies that change. This asymmetry explains why “being on Amazon” requires ongoing monitoring, like on any major marketplace.
For the catalog, the same reference can exist under several offers: your listing is distinguished by price, lead times, new or used condition, and service history. The “product page” is therefore not equivalent to a category page on your site where you are the sole owner of the message.
A useful clarification for product and legal teams: the general terms and conditions displayed on your D2C site do not apply as-is to sales made via Amazon; each channel has its own policies and mediation mechanisms.
For founders comparing fundraising and channels, investors often question reliance on a single marketplace: diversifying toward your own site and other channels reduces concentration risk.
Summary
Three possible meanings of the word “platform” at Amazon
1) The consumer marketplace: millions of buyers search and buy on Amazon; third-party sellers list offers, often competing on the same product detail page.
2) Seller tools: Seller Central brings together listings, inventory, orders, performance, paid advertising on Amazon, compliance.
3) Other group businesses: web services (AWS), content, etc. That is not what most merchants mean when they say «sell on Amazon», but the term «platform» is confusing.
What it is not about
Amazon does not provide you with an independent domain name and site identity like a traditional store builder: you operate within the Amazon environment, under its terms.
Common confusion with AWS
Amazon Web Services (AWS) is another «platform»: cloud infrastructure for hosting sites, APIs, databases. A developer can use AWS to run a store independent of Amazon retail: this does not mean selling on the consumer marketplace.
Buy Box and competition
When several sellers offer the same product, the interface highlights a main offer (often called Buy Box in seller jargon) based on price, availability, and service criteria. Understanding this mechanism is central to pricing strategy, beyond the simple wording on the listing.
Seller Central: the seller dashboard
Seller Central is the portal where third-party sellers manage their business after signing up: catalog, pricing, shipping, disputes, reports. It is the functional equivalent of “marketplace back office” for the seller account.
Registration and verification
Amazon requires identity documents, tax and banking information, and sometimes additional supporting documents depending on the category: the process aims to reduce fraud and protect buyers. Detailed steps are included in the official registration guides on sell.amazon.fr.
Seller performance
Service metrics (shipping times, cancellations, claims) affect your visibility and account health: handle them with the same rigor as an SLA on your own site.
Reports and accounting
Seller Central aggregates sales, fees, refunds and payments: regularly export them to your accounting tool; payout periods and reserves for disputes affect cash flow like on any marketplace (see the article cited in the introduction).
Seller University
Amazon offers training content for new sellers: useful for the basics, without replacing a financial and legal strategy adapted to your company.
Individual and Professional Sales Plans
Amazon typically offers a per-item commission plan and a Professional plan with a monthly subscription suited to higher volumes. Exact amounts, VAT, and thresholds change: the Pricing page is authoritative.
Economic analysis
The right plan depends on volume and margin: model sales fees + logistics cost + advertising before projecting profitability.
Referral fees
Category-based commissions apply in addition to the plan: they reduce margin like on any marketplace (same framing article as in the introduction).
Variable fees and promotions
Certain options (coupons, deal types like Lightning Deals depending on eligibility) affect visibility and margin: read the eligibility conditions and schedule before committing stock.
Seller payments
The official FAQ explains that Amazon generally holds proceeds for a certain number of days after delivery to cover refunds; the default delay is often presented as “DD+7” (to be confirmed in the current help). Factor this lag into your cash flow plan.
Calculator and simulations
Amazon provides revenue estimators and fee simulators on its seller pages: use them with realistic, not optimistic, assumptions for selling price and purchase cost.
Shipping: FBA, FBM and associated programs
Fulfilment by Amazon (FBA): you send stock to Amazon centers; the platform handles storage, picking, delivery to the end customer, and part of customer service for these orders, according to the program rules. For general logistics vocabulary: e-commerce fulfillment services.
Fulfilment by Merchant (FBM): you ship it yourself from your premises or through a third-party provider: more direct control, more operational burden.
Stock and seasonality
Long-term storage and excess inventory cost money: anticipate peaks and unsold items as with any warehouse, with Amazon-specific pricing rules.
Returns
FBA returns follow Amazon processes; keep accounting and quality oversight aligned with your overall returns policy.
Prime and customer experience
Eligible Prime offers benefit from high delivery expectations on the customer side: your ability to meet deadlines influences reviews and performance. The FBA program is often used to meet these expectations, at the cost of integrated logistics fees.
Multi-site inventory
Distributing stock across several countries or centers increases complexity: monitor transfers, hidden costs, and perishable or seasonal products.
Vendor Central and wholesale to Amazon (1P)
Outside the scope of the classic third-party seller model, some brands sell in wholesale to Amazon, which then resells them (often referred to as « 1P » in practitioner jargon). The tools, margins, and negotiations differ from the Seller model: it is not the same business as opening a standard Seller Central account.
Do not mix them
Teams, finance, and commercial terms are not interchangeable between 1P and 3P: clarify the model before hiring or investing.
Commercial negotiation
The 1P model often involves annual negotiations, assortments, back margins: it is closer to a distributor relationship than to a simple online account.
Amazon Business: the B2B channel
Amazon Business offers features suited to business purchasing (multi-user accounts, invoicing compliance depending on the case, quotes) alongside the consumer channel. Useful for some industrial suppliers or supplies; pricing positioning and competition still need to be analyzed sector by sector.
Link with your strategy
If you are already in B2B on your site, check that your prices, discounts, and terms are consistent with what you publish on Amazon Business.
Public purchasing
Some features are aimed at organizations that buy in a regulated environment: check whether your offer is compatible with the invoicing or traceability requirements of public procurement entities.
Brand: Brand Registry, enhanced content, protection
Trademark owners can enroll in Amazon Brand Registry to access anti-counterfeit protection tools, enhanced content (A+ pages, videos), and analytics. The prerequisites and features are described in the official seller help.
Product experience
Rich content improves conversion and clarity; it complements but does not replace a sound pricing and logistics strategy.
Review transparency
Customer reviews are a pillar of trust on Amazon; any prohibited practice of fake incentivization exposes you to penalties. Stay aligned with the platform rules and consumer law.
Storytelling
Brand pages make it possible to tell the origin and values: useful for differentiation when competitors copy the technical specifications.
Visibility: internal search and advertising on Amazon
Most journeys start with Amazon search: titles, bullet points, backend keywords, and historical performance play a role comparable to SEO, but on a closed algorithm.
Sponsored Products and retail media
Advertising on Amazon makes it possible to buy visibility through auctions; budget and profitability must be tracked like any paid channel. Cross-check with a broader analytics view if you are operating across multiple channels.
Web SEO vs Amazon search
Work on your website's SEO does not directly feed Amazon's internal ranking: two complementary skills if you are playing both channels.
Reviews and conversion rate
On the Amazon product page, average rating and number of reviews strongly influence clicks; on your site, you combine social proof, brand content, and funnel optimization (see blog conversion articles).
International: Europe accounts and expansion
Amazon often makes it possible to structure a presence across several European marketplaces from a unified account logic (depending on offers and periods). Taxes, product compliance, and cross-border shipping still need to be managed country by country.
EU Compliance
Labeling, product registers, packaging: local requirements still apply even when sales go through Amazon; seller support and European portals complement legal advice.
United Kingdom and Switzerland
Outside the European Union, customs and VAT become issues that must be handled specifically again: do not mechanically duplicate a "unified EU" strategy without tax verification.
Languages and Customer Service
Selling in several countries often comes with language expectations for listings and customer service: anticipate translation and moderation costs.
Risks: suspensions, product compliance, intellectual property
An account may be restricted in the event of non-compliance with policies (prohibited products, missing documentation, repeated complaints). Prevention is better than emergency reactivation.
Regulated products
Certain categories require prior approval; others are reserved or prohibited for third-party sellers: lists to consult in the official help.
Counterfeiting
List only authorized products; IP disputes can close accounts and engage your liability.
Reviews and seller community
Seller forums and the official help are useful but non-legal sources: if in doubt about a policy interpretation, seek professional advice.
Price monitoring
Amazon sometimes announces adjustments to commissions or logistics fee schedules by category: include a quarterly review of official announcements in your finance routine.
In short, on the seller side, the "Amazon e-commerce platform" is mainly the combination of marketplace + Seller Central + shipping and visibility programs, with proprietary rules to follow before highlighting gross sales.
Amazon and your D2C site: complementarity with Shopify and Qstomy
Many brands combine Amazon for discovery and volume, and a proprietary site for margin, community, and first-party data. On the site side, a stack like Shopify with an AI chatbot for e-commerce (Qstomy) for support and assisted selling remains the place where you fully control the journey.
Cannibalization and pricing
Align your product strategy (exclusives, bundles) to prevent the marketplace channel from eroding perceived value on D2C without a clear strategy.
Data
Customer data and the direct relationship are generally richer on your store: use them to build loyalty beyond the last Amazon search.
Newsletter and LTV
Building an email list from your site (with consent) strengthens LTV independently of marketplace algorithms (see the blog guide on retention and customer lifetime value).
Omnichannel journey
The customer may discover the brand on Amazon and then go to your site for a premium purchase or a limited edition: communicate clearly to avoid confusion over references.
Third-party tools and ERP
Many vendors offer connections between Seller Central and ERP systems, repricing tools, or ad management tools: useful at scale, with the risk of over-automating without human oversight of margins. Choose integrations that respect Amazon API terms of use.
Team and skills
An "Amazon manager" profile combines financial understanding (actual fees), product sense (compliance, listings), and stress resilience during peaks (Prime Day, Black Friday). It is not exactly the same profile as a D2C site acquisition manager, even though the two must work together.
Relationship with traditional distribution
If you also sell in stores or through wholesalers, non-compete or pricing clauses may come into tension with an aggressive presence on Amazon: anticipate negotiations with your long-standing partners.
Finally, remember that "the Amazon platform" for a third-party seller is not software that you "own": it is a regulated environment where business continuity depends on complying with the rules and maintaining realistic financial management, just like any other e-commerce channel (see the foundations mentioned in the introduction).
FAQ and sources
Is Amazon an e-commerce platform in the same way as Shopify? No, not in the same way: Shopify lets you own a store on your domain; Amazon hosts you as a seller on its marketplace.
Can you « install » Qstomy on Amazon? Not like on Shopify: Qstomy integrates with your site and the channels you control; Amazon is managed via Seller Central and the ecosystem of apps and services provided by Amazon.
Where should you start with the documentation? Amazon France seller guides and pricing, updated by Amazon.
Qstomy internal linking
Articles already mentioned: marketplace, e-commerce foundations, fulfillment, returns, site SEO, Shopify, AI chatbot. For conversion, funnel and analytics, see the corresponding guides on the blog.
