Marketplace integration

When Amazon, eBay, or Etsy inventory and orders live outside Shopify, you oversell, reconcile manually, and lose visibility into which channel is actually profitable. Shero integrates Shopify with Amazon, eBay, Etsy, Walmart, and other marketplaces so inventory levels, order data, and listing content stay in sync across every channel from a single Shopify admin.

Shopify marketplace integration: what it covers

Shero builds marketplace integrations for brands selling on Amazon, eBay, Etsy, Walmart, and other channels, using Shopify Marketplace Connect, third-party connectors such as Codisto and Sellbrite, or custom API connections for marketplace platforms without standard connectors.

Why multi-channel brands work with Shero on marketplace integration

Marketplace integrations that manage inventory correctly for two channels fail at five. The inventory allocation logic, listing sync rules, and order routing decisions that work at small scale need to be designed for your actual channel mix.

01

Inventory allocation designed for your channel mix

Sharing a single inventory pool across Shopify, Amazon, and eBay requires allocation rules that prevent overselling when multiple channels draw from the same stock simultaneously. Shero designs the allocation logic before building the integration, defining how available inventory is shared, reserved, and updated across channels.

02

Listing content managed from Shopify, not from each marketplace separately

Managing product listings in each marketplace admin separately creates content drift and consumes catalog team time. Shero configures the integration to push listing content from Shopify to each marketplace, so a product update in Shopify publishes to Amazon, eBay, and other channels without a separate update step.

03

Orders from every channel routed to Shopify for unified fulfilment

A complete marketplace integration routes orders from Amazon, eBay, and other channels into Shopify as Shopify orders. Your fulfilment team works from one order queue. Reporting covers all channels. Returns and refunds are managed from one admin. The marketplace becomes a sales channel, not a separate operation.

04

Brand control across marketplaces for established brands

Brands with an active dealer network or premium positioning need to control how their products appear on marketplace channels. Shero configures listing templates, pricing rules, and authorised seller management so the brand's marketplace presence matches its positioning and protects against unauthorised resellers.

05

Amazon-specific optimisation for brands building a marketplace presence

Amazon's search algorithm, A+ Content, Brand Registry, and advertising platform require Amazon-specific configuration beyond a basic product sync. Shero handles Amazon-specific listing optimisation, Brand Registry setup, and advertising strategy as part of the marketplace integration scope for brands building a meaningful Amazon presence.

06

Marketplace integration maintained as channels and connectors evolve

Marketplace APIs change. Connector platforms release updates. Listing policy requirements shift. Shero provides ongoing marketplace integration support so that the connection between Shopify and your marketplace channels stays current without your team having to monitor every platform update across five channels simultaneously.

How Shero builds Shopify marketplace integrations

01

Discovery: Channel Mix and Inventory Mapping

We document every marketplace channel, your inventory allocation rules, listing content requirements, channel-specific pricing, and order routing requirements. We identify which connector approach covers your channel mix and what custom configuration is required for each marketplace.

02

Architecture: Integration and Allocation Design

We design the inventory allocation model, listing sync logic, order routing rules, and channel-specific pricing configuration. For Amazon, we design the Brand Registry and listing optimisation scope alongside the technical integration.

03

Build: Connector Configuration and Listing Setup

We configure the marketplace connector or custom integration, map listing content fields from Shopify to each marketplace format, set inventory allocation rules, and configure order routing. For Amazon-specific requirements, Brand Registry setup and A+ Content configuration run in parallel.

04

UAT: Cross-Channel Inventory and Order Validation

We test the full cycle: listing published to marketplace, sale on marketplace, inventory updated in Shopify, order routed to Shopify for fulfilment. We test concurrent sales across channels to validate that inventory allocation prevents overselling.

05

Launch and Channel Monitoring

Go-live includes monitoring for the first sync cycles across all channels, a runbook for your catalog team covering listing updates and inventory management, and a defined support arrangement for marketplace policy changes and connector updates.
