About this Product
The Asos Marketplace Connector is a custom integration that ECOSIRE builds, installs and supports for your store — it is not an instant Shopify App Store download. After purchase, our team scopes your fashion catalog, builds the connector against your exact size curves and attribute taxonomy, and deploys it to your Shopify store.
The connector keeps your Shopify product catalog and the Asos marketplace in continuous sync. We map your Shopify products, variants and metafields to Asos's fashion taxonomy — brand, category, colour, size and material attributes — so listings meet Asos's strict content and image requirements before they go live. Stock and price changes propagate both ways: we read your multi-location inventory through the Shopify Admin GraphQL API and push adjusted availability to Asos, so you never oversell a size that just sold in-store.
On the order side, Asos orders are imported into Shopify as native orders with correct customer, line-item and tax data. Fulfilment and tracking sync back to Asos automatically, and returns flow back into Shopify so refunds and restocks stay accurate. We use Shopify webhooks (orders/create, inventory_levels/update, products/update) plus scheduled reconciliation jobs to keep both systems honest, with retry and conflict handling for the cases real catalogs hit.
Because it is built to order, the connector fits your actual SKU structure, size attribute mapping and bulk-listing workflow rather than forcing a generic template. You get a working integration installed on your store, documentation, and ongoing support from the team that built it. Typical delivery is a few weeks depending on catalog complexity and Asos onboarding status.

Who this is for
Fashion brand scaling onto Asos
An established Shopify fashion brand approved for the Asos marketplace that needs its full catalog, stock and pricing pushed to Asos without rebuilding listings by hand.
Multi-channel apparel merchant
A merchant already selling across their own store and other channels who needs Asos orders flowing into Shopify as the single source of truth for inventory and fulfilment.
Operations lead tired of overselling
An ecommerce or operations manager who keeps overselling popular sizes because Asos stock and Shopify multi-location inventory drift apart, and wants automated two-way sync.

Frequently Asked Questions about Asos Marketplace Connector
Is this an instant download from the Shopify App Store?
No. This is a build-to-order integration. After purchase, ECOSIRE scopes your catalog and Asos setup, builds the connector to fit your store, and installs it for you. You are buying a custom-built and installed solution, not a self-serve App Store app.
How long does delivery take?
Typical delivery is a few weeks, depending on your catalog size, how complex your size and attribute mapping is, and your Asos marketplace onboarding status. After purchase we confirm a timeline during the scoping call before any build work starts.
What ongoing support and updates do I get?
The connector is supported by the team that built it. Post-launch support is included, and we maintain the integration against Shopify Admin API changes and Asos requirement updates. Larger feature additions or catalog expansions can be quoted as follow-on work.
Do I need an approved Asos marketplace seller account?
Yes. Asos must approve you as a marketplace seller and provide the API or feed access for your account. We build and connect the integration; we cannot grant Asos approval on your behalf, but we work with whatever access Asos provisions for you.
Will it prevent overselling between Shopify and Asos?
Yes. The connector reads your Shopify multi-location inventory and syncs availability to Asos via webhooks and scheduled reconciliation, so a size that sells on either channel is decremented on both. We include conflict and retry handling for edge cases, though sync is near-real-time rather than literally instantaneous.
