About this Product
The US Marketplaces Bundle connects a single Magento 2 (Open Source or Adobe Commerce) catalog to the three largest US marketplaces — Amazon (SP-API), eBay (Sell API) and Walmart Marketplace API — through one coherent set of modules installed under app/code/Ecosire/ on your own store. It is not an instant Adobe Commerce Marketplace download: ECOSIRE builds it to fit your catalog structure, attribute set and warehouse setup, then installs and supports it on your environment.
The core problem it solves is overselling across channels. A shared inventory pool reads salable quantity from Magento's Multi-Source Inventory (MSI) via the getProductSalableQty service contract and pushes a single authoritative figure to all three marketplaces, so a unit sold on eBay decrements availability on Amazon and Walmart within the same sync cycle. Sync runs on Magento cron through queue consumers, with retry and backoff so marketplace rate limits never silently drop updates.
Each channel keeps its own rules. Per-channel listing & pricing lets you map Magento attributes to Amazon listing feeds, eBay item specifics and Walmart spec fields, apply channel price markups or floors, and control which website/store-view supplies titles and descriptions. Unified order import pulls marketplace orders back into native sales_order records — with marketplace fees, buyer-shipping and channel reference stored as order attributes — so fulfillment, invoicing and credit memos run through your existing Magento workflow.
Everything respects Magento conventions: dependency injection via di.xml, plugins/observers instead of core rewrites, admin ACL for each marketplace config, REST/GraphQL endpoints for status, and structured logging. You get a maintainable extension your developers can read — not a black box. ECOSIRE delivers, installs, and supports it, with a clear lead time agreed up front.

Who this is for
US merchant launching multichannel in one purchase
A Magento 2 store owner who wants to go live on Amazon, eBay and Walmart together rather than buying and wiring three separate connectors. Values one shared inventory source of truth and a single point of support.
Operations manager fighting overselling
Runs fulfillment across channels and is tired of cancellations and marketplace account-health hits caused by stale stock. Needs salable quantity synced from MSI across all three marketplaces on a reliable cron cycle.
Magento developer or agency lead
Owns the codebase and refuses black-box extensions. Wants DI-based, ACL-protected, observer-driven code under app/code/Ecosire/ with a handover doc, so the team can maintain and extend it after delivery.

Frequently Asked Questions about US Marketplaces Bundle (Amazon + eBay + Walmart)
Is this an instant download from the Adobe Commerce Marketplace?
No. This is a build-to-order extension. ECOSIRE builds the bundle to fit your catalog, attribute sets and warehouse setup, then installs it under app/code/Ecosire/ on your own Magento 2 store and connects your Amazon, eBay and Walmart accounts. There is no instant Marketplace download or auto-provisioned license.
What is the delivery lead time after I purchase?
Typical delivery is around one working week depending on your catalog size, the complexity of your attribute and category mappings, and how quickly marketplace API access is granted on your seller accounts. After purchase we confirm a concrete timeline with you up front, then build, install on your environment, and run connected end-to-end tests before go-live.
Do I get ongoing support and updates?
Yes. Each build includes a post-launch support window covering bug fixes and compatibility updates when Amazon SP-API, eBay Sell API or Walmart Marketplace API change. Longer-term support and enhancement plans are available so the integration keeps working as marketplaces and your Magento version evolve.
How does it actually prevent overselling across the three channels?
The shared inventory pool reads salable quantity from Magento's Multi-Source Inventory using the getProductSalableQty service contract and pushes one authoritative figure to all three marketplaces on each sync cycle. When a unit sells on any channel, the order import decrements stock in Magento, and the next sync propagates the new quantity to the others, with retry and backoff so rate limits never silently drop an update.
Will it work with Adobe Commerce as well as Magento Open Source, and does it touch core?
It works with both Magento Open Source and Adobe Commerce. It is built the Magento way using dependency injection via di.xml, plugins/interceptors and observers on events, with admin ACL on every config resource. It does not rewrite or patch core classes, so it stays upgrade-friendly and your developers can read and extend it from the handover documentation.
