This is a build-to-order Magento 2 extension, not an instant Adobe Commerce Marketplace download. ECOSIRE builds the connector against your Dynamics 365 Business Central tenant and your Magento Open Source or Adobe Commerce install, then installs and supports it on your environment.

The module ships under app/code/Ecosire/DynamicsBcConnector and integrates the Magento way: observers on sales_order_place_after and sales_order_invoice_register capture finance events, plugins/interceptors wired through di.xml enrich customer and item data, and a service-contract API layer (Api/ interfaces with Model/ implementations) keeps the integration testable and upgrade-safe. Outbound calls reach Business Central through its OData v4 / REST API using OAuth 2.0 (Azure AD) authentication — token acquisition, refresh and per-company endpoint routing are handled server-side, never exposed to the storefront.

Heavy work runs asynchronously: a Magento cron group drains a retry-safe queue so a Business Central timeout never blocks checkout. Every push is idempotent (external-ID keyed) so retries don't double-post invoices. Admin ACL resources gate a configuration and sync-monitor screen under Stores → Configuration, and structured logging lands in var/log/ecosire_bc.log for traceability.

Functionally it covers sales order and invoice posting into Business Central, customer and item master sync, inventory and price sync back to Magento, and configurable tax group and dimension mapping (department, cost center, project) so postings land in the right GL buckets.

Because it's bespoke, field mappings, company selection, multi-warehouse rules and your specific BC extensions/customizations are scoped during a short discovery call before a line of code ships. You get the full source, a documented mapping config, and a support window — not a black-box subscription. Compatible with Magento 2.4.x and Business Central SaaS or on-prem (with a reachable API endpoint).
