WooCommerce Multi-Warehouse Inventory

Key Features

**Unlimited warehouse locations** registered as a dedicated custom post type, each with address, geo-coordinates, fulfillment priority and enabled shipping regions

**Per-warehouse stock levels per SKU and variation**, stored in a custom table keyed by product/variation ID + warehouse ID rather than a single `_stock` meta value

**Nearest-warehouse order routing** that geocodes the customer shipping address and scores warehouses by distance, in-stock availability and configured priority

**Split-shipment handling** that divides a cart across multiple warehouses when no single location can fulfill it, with each leg tracked separately

**Location-based shipping cost calculation** via a custom WooCommerce shipping method and `woocommerce_package_rates` filtering, so rates match the shipping warehouse

**HPOS / custom order tables compatible** — stock allocation is written against the order record, not fragile post meta

**WooCommerce REST API endpoints** for reading and updating per-location stock so your WMS, ERP or 3PL can sync programmatically

**Developer hooks, actions and filters** to override routing logic, allocation rules and warehouse selection from your own code

**wp-admin warehouse management screens** for stock transfers between locations, per-location reorder thresholds and stock adjustment logging

**WP-Cron low-stock recalculation** and per-warehouse low-stock email notifications to the right fulfillment team

**Atomic stock decrement on order placement** with locking to prevent overselling a depleted warehouse under concurrent checkouts

**WPML and WordPress multisite aware** so localized catalogs and network stores resolve to the correct shared or per-site warehouse data

About this Product

WooCommerce core gives you one stock number per product — a single _stock meta value with no concept of where that stock physically sits. If you run two or more warehouses, that single number forces manual reconciliation, oversells from depleted locations, and shipping quotes that ignore which warehouse will actually fulfill the order.

WooCommerce Multi-Warehouse Inventory replaces that single counter with per-location stock ledgers per SKU. Each warehouse is a custom post type record (address, geo-coordinates, priority, enabled regions). Stock is stored in a dedicated custom table keyed by product/variation ID and warehouse ID, so availability is resolved per location rather than globally — and it stays accurate under HPOS / custom order tables because allocation writes against the order, not fragile post meta.

At checkout, a nearest-warehouse routing engine geocodes the customer's shipping address and scores each warehouse by distance, stock availability and your configured priority — then allocates the order to the best fit. When no single warehouse can cover the cart, split-shipment handling divides the order across locations and exposes each fulfillment leg in wp-admin and the REST API. Location-based shipping cost calculation plugs into the WooCommerce shipping framework (a custom shipping method plus woocommerce_package_rates filtering) so the rate reflects the warehouse that actually ships each package.

Everything is exposed through WordPress hooks, actions and filters and WooCommerce REST API endpoints, so your WMS, ERP or 3PL can read and adjust per-location stock programmatically. Low-stock recalculation runs on WP-Cron.

This is a build-to-order plugin. ECOSIRE scopes it to your catalog, warehouse list and shipping rules, then builds, installs and configures it on your WordPress site — including data migration of your existing stock into per-location ledgers. It is not an instant marketplace download; you get a plugin engineered for your store and a team that supports it.

Who this is for

Multi-location retailer

Runs two or more physical stores or stockrooms on one WooCommerce site and needs each order to draw from — and ship from — the location nearest the customer to cut delivery time and cost.

Distributor / wholesaler

Holds inventory across regional warehouses and needs accurate per-location availability, split shipments for large orders, and REST API sync with an existing ERP or WMS.

WooCommerce store operations manager

Owns fulfillment accuracy and wants to stop overselling from depleted locations, automate warehouse selection at checkout, and give each fulfillment team its own low-stock alerts.

Frequently Asked Questions about WooCommerce Multi-Warehouse Inventory

How long does delivery take, since this is built to order?

After we confirm scope — your catalog size, number of warehouses, routing rules and shipping logic — a typical build is delivered in about 2 to 4 weeks. We install on a staging copy of your site first, validate stock migration and routing against real orders, then move it to production with you. We share a firm timeline in writing before any work starts; complex ERP/WMS integrations or large catalogs may extend it.

What ongoing support and updates do I get after launch?

Every build includes a post-launch support window for bug fixes and a compatibility commitment: we keep the plugin working across WooCommerce and WordPress core updates, including HPOS changes. After the included window you can keep ECOSIRE on a maintenance arrangement for continued updates, new features and priority support. Because you own the installed plugin, you are never locked out of your own store.

Will it work with HPOS (High-Performance Order Storage) and my existing theme/plugins?

Yes. The plugin is built against WooCommerce's HPOS / custom order tables API rather than legacy post meta, and stock allocation is written to the order record. During scoping we review your active theme, shipping plugins and payment gateways for conflicts, and we test the build on a staging clone of your real site before go-live.

Can it sync with my ERP, WMS or 3PL?

Yes. Per-location stock is exposed through dedicated WooCommerce REST API endpoints and WordPress hooks, so external systems can read and update warehouse stock programmatically. If you need a specific connector (for example to push allocations to a 3PL or pull stock from an ERP), we scope that integration as part of the build.

How is the nearest warehouse actually chosen?

At checkout the plugin geocodes the customer's shipping address and scores each enabled warehouse using distance, current in-stock availability for the ordered SKUs, and the fulfillment priority you set. The highest-scoring warehouse that can cover the cart is allocated the order; if none can cover it alone, the order is split across the best combination of locations. The scoring logic is exposed via filters so your developers can override it.
