Magento 2 ships with strong sell-side commerce but no native procurement layer — suppliers, purchase orders, RFQs and incoming-shipment receiving all live in spreadsheets or a disconnected ERP. This extension closes that gap inside the Magento admin, so your buyers raise POs against the same catalog and stock the storefront sells from.

This is a build-to-order module, not an instant Adobe Commerce Marketplace download. ECOSIRE engineers it against your Magento version (Open Source or Adobe Commerce), your MSI source/stock setup, and your supplier workflow, then installs and supports it on your environment.

Delivered as a proper module under app/code/Ecosire/PurchaseOrder, it uses Magento's real architecture: service contracts and repository interfaces for supplier/PO data, di.xml for dependency injection, plugins/interceptors to hook catalog and inventory flows, and observers on events like sales_order_place_after to drive low-stock and backorder PO suggestions. New entities ship with declarative-schema db_schema.xml tables, admin grids built on UI components, and full admin ACL so only authorized roles touch procurement.

Buyers manage suppliers and supplier-specific pricing, generate purchase orders manually, from low-stock triggers, from backorders, or by CSV import, and run lowest-price supplier comparison to auto-select the cheapest qualified supplier per SKU. Quotation / RFQ records capture supplier responses before a PO is committed. On delivery, incoming-shipment receiving updates MSI source_item quantities and writes inventory movements — partial receipts included.

Everything is reachable over REST and GraphQL service contracts for ERP, BI or supplier-portal integration, and scheduled cron jobs handle reorder-point scans and stale-quotation cleanup. You get the full source code, no per-seat license, and a fixed delivery window.
