WooCommerce Multichannel Marketplace Sync turns your WordPress store into the control tower for every channel you sell on. Instead of logging into Amazon Seller Central, eBay, Walmart and Etsy separately, you list, price and fulfill from wp-admin — and inventory stays accurate everywhere.

This is a build-to-order plugin. After purchase, ECOSIRE builds, installs and configures it directly on your WordPress site against your specific marketplace accounts, product taxonomy and warehouse setup. There is no instant download — you get a plugin engineered for your catalog, not a generic listing tool you have to wrestle into shape.

Under the hood it reads your WooCommerce products (including variations) and publishes them to each marketplace through that marketplace's official Seller/Listings API, with per-channel category, attribute and price mapping so the same product meets Amazon, eBay and Etsy's very different field requirements. A WP-Cron–driven sync engine (upgradeable to a real system cron for high volume) reconciles stock levels in near real time, applies per-channel stock buffer rules, and triggers inventory threshold updates the moment a sale lands — the core defense against overselling across channels.

Incoming marketplace orders are imported as native WooCommerce orders (fully HPOS / custom order tables compatible), so your existing fulfillment, shipping, invoicing and reporting plugins just work. Order status, tracking and cancellations flow back to the originating marketplace automatically.

Built with WordPress hooks, actions and filters so it extends cleanly, respects your theme and other plugins, and stays upgrade-safe. WPML and multisite scenarios are supported on request. ECOSIRE handles the marketplace API credentials, throttling, error logging and edge cases — and stays on for support.
