The Multichannel Marketplace Hub is a custom-built Business Central extension (AL language) that turns your BC tenant into the single source of truth for selling across Amazon, eBay, Walmart, Etsy and hundreds of other marketplaces and storefronts. Instead of staff re-keying listings and orders into separate seller portals, the Hub keeps items, prices, stock, orders and fulfilment flowing automatically through one connector.

This is not an instant Microsoft AppSource download. ECOSIRE builds the extension to your channel mix and item structure, installs it as a per-tenant extension on your Business Central environment (cloud SaaS or on-prem), and supports it afterwards. We scope which marketplaces you sell on, map your BC items and units of measure to each channel's listing model, and configure the polling cadence and tax/pricing rules before go-live.

Technically, the Hub adds table and page extensions over Item, Sales Order and Sales Shipment, plus dedicated channel-listing and sync-log tables. Event subscribers on item, inventory and shipment posting fire near-real-time updates; the Job Queue drives scheduled marketplace polling for new orders and acknowledgements. Outbound and inbound traffic uses the marketplace APIs through a gateway, while BC's own REST/OData v4 API stays available for your other integrations. Dedicated permission sets scope who can manage listings versus who can run syncs, and every sync writes an auditable log entry.

The result: inventory that does not oversell across channels, orders that land directly in BC as sales orders, and shipment tracking written back to each marketplace from your posted Sales Shipments — all governed by your existing BC posting, costing and approval rules.
