Purchase Orders, Suppliers & Multi-Warehouse Inventory for WooCommerce — Free

Run a complete supplier-to-shelf workflow inside WordPress — free, with no monthly fee and no SaaS account required. Built specifically for WooCommerce stores that have outgrown basic stock management but don’t want to pay enterprise prices for inventory software.

Create purchase orders by SKU, send them to suppliers, receive stock in one click, and watch WooCommerce stock counts update automatically — including per-warehouse counts if you run multiple locations or use OpenPOS. All from a clean new WC-Manager menu in your WordPress admin.

Free forever. Why?

We build a paid SaaS dashboard at wc-manager.com that adds AI insights, reports, restock forecasting and live POS feeds on top of the same data. The procurement modules in this plugin stay free for everyone — most stores need basic purchase orders before they need analytics, and we’d rather earn your trust now than charge you for the basics.

What you get, for free

Purchase Orders * Build a PO by SKU — variations fully supported. * Mark as draft, send, partial, received or cancelled with a clear status workflow. * Receive in one click — WooCommerce stock_quantity, manage_stock and stock_status are bumped automatically. * Per-warehouse stock updates if the receiving warehouse is mapped to an OpenPOS outlet (the _op_qty_warehouse_{id} meta OpenPOS uses). * Auto-generated PO numbers (PO-00001, PO-00002, …). * Notes, line-item costs and a running subtotal.

Suppliers directory * Name, email, phone, payment terms and lead time. * Keep all your supplier contacts in one place — no more digging through emails or spreadsheets.

Warehouses / stock locations * Define your physical stock locations. * Optionally map each one to an existing OpenPOS outlet so receives write to the same per-location meta key OpenPOS already uses — no double counting, no drift.

Secure REST API * Endpoints under /wp-json/woo-manager/v1/ for suppliers, warehouses and purchase orders (GET, POST, PUT, DELETE). * Authenticates with your existing WooCommerce REST consumer key — no new connection key, no WordPress Application Password. * Read-only data endpoints for OpenPOS outlets/registers, TeraWallet/WooWallet balances and WooCommerce Memberships (data WooCommerce’s standard REST API can’t see).

OpenPOS terminal panels (optional) * Members panel — cashiers look up a customer at the register and see their active WooCommerce Memberships. * Stock Take panel — run a category-by-category count at the register; counts auto-save.

Telegram alerts (free) * Real-time notifications for every new WooCommerce order to any Telegram chat — group, channel or DM — via the WC-Manager bot. * Hooks woocommerce_new_order (and optionally woocommerce_order_status_changed) and forwards instantly — sub-second alerts on every checkout. * Manage chats from WP admin (WC-Manager → Telegram): chat ID, events (new / completed / refunded / PO received / low stock / new customer), order-status filter, POS-only vs Online-only filter (when OpenPOS is detected), minimum order total, custom HTML template. * Same config syncs with the WC-Manager dashboard — manage from either place. * Customer notes & tags syncing (VIP, wholesale, prefers WhatsApp, at risk, etc.) keyed by email so guest checkouts are annotatable too — managed under WC-Manager → Customer Notes.

Install once, activate. There is nothing to configure for the free procurement features.

Problems this plugin solves

• “I can’t manage purchase orders inside WooCommerce.” → Built-in PO module, free.
• “I lose track of which supplier sent which order.” → Suppliers directory linked to every PO.
• “Stock at my second outlet is invisible from WP admin.” → Multi-warehouse, with OpenPOS outlet sync.
• “Receiving stock means hand-editing every product.” → One-click receive bumps WC stock automatically.
• “I want to know the second an order comes in.” → Free Telegram alerts to your phone, group, or warehouse screen — sub-second.
• “Different staff use different spreadsheets.” → One source of truth, in WordPress, with the rest of your store.

Optional upgrade — WC-Manager dashboard

Want analytics and AI on top of all this? Connect a free WC-Manager account at wc-manager.com and the same suppliers, POs and warehouses sync both ways with our hosted dashboard, which adds:

• AI Insights — plain-English summary of your sales, customers and POS data with action list and business valuation.
• AI product descriptions — generate SEO-ready copy in your chosen tone and push to WooCommerce in one click.
• Reports — profit by month or year, units sold, order-timing heatmap, repeat-buyer rate and customer lifetime value.
• Multi-location stock transfers — move inventory between warehouses with full audit trail.
• Restock Predictor — velocity-based reorder forecasts so you never run out of best sellers.
• Spreadsheet product editing — bulk-edit prices, stock, supplier prices and meta fields.
• Live POS feed — real-time sales view across all outlets and registers.
• Membership management, category stock takes, full activity log, team access.

Free plan available. No credit card to start.

Works great with

• OpenPOS — outlets, registers, the in-terminal Members & Stock Take panels, and per-warehouse stock that stays in sync with the same meta key OpenPOS uses (_op_qty_warehouse_{id}).
• WooCommerce Memberships — read plans and per-customer memberships.
• TeraWallet / WooWallet — read store-credit balances.
• Telegram — instant order notifications via the WC-Manager bot (@wc_manager_bot) — add it to any group, channel or DM, send /id, paste into the plugin’s Telegram page.
• Works on any store running standard WooCommerce too — the optional integrations only activate when their host plugin is present.

REST endpoints

All endpoints authenticate with your existing WooCommerce REST consumer key (or any logged-in user with the manage_woocommerce capability). No separate connection key needed.

Procurement (free):

• GET, POST /wp-json/woo-manager/v1/suppliers — list / create suppliers.
• GET, PUT, DELETE /wp-json/woo-manager/v1/suppliers/{id} — read / update / delete one supplier.
• GET /wp-json/woo-manager/v1/warehouses — list warehouses.
• GET, POST /wp-json/woo-manager/v1/purchase-orders — list / create POs.
• GET, DELETE /wp-json/woo-manager/v1/purchase-orders/{id} — read / delete one PO.
• POST /wp-json/woo-manager/v1/purchase-orders/{id}/send — mark a PO as sent.
• POST /wp-json/woo-manager/v1/purchase-orders/{id}/cancel — cancel a PO.
• POST /wp-json/woo-manager/v1/purchase-orders/{id}/receive — receive stock (updates WooCommerce stock + per-warehouse meta).
• POST /wp-json/woo-manager/v1/purchase-orders/{id}/sync-receive — bump qty_received without touching WooCommerce stock (used when the dashboard already updated stock itself).

OpenPOS, wallet & membership reads:

• GET /wp-json/woo-manager/v1/openpos-outlets — OpenPOS outlets (_op_warehouse posts).
• GET /wp-json/woo-manager/v1/openpos-registers — OpenPOS registers (_op_register posts).
• GET /wp-json/woo-manager/v1/terawallet/balances — users with a non-zero TeraWallet balance.
• GET /wp-json/woo-manager/v1/terawallet/balance/{user_id} — a single user’s TeraWallet balance.
• GET /wp-json/woo-manager/v1/memberships/plans — WooCommerce Memberships plans.
• GET /wp-json/woo-manager/v1/memberships/user/{user_id} — a user’s memberships.

OpenPOS panels (optional)

• Members — cashiers can look up a customer at the register and see their active WooCommerce Memberships.
• Stock Take — run a category-by-category stock count at the register; counts auto-save and sync to the WC-Manager web app.

External service

The Stock Take panel communicates with the WC-Manager web app at https://wc-manager.com to load and save stock takes for your organisation. It authenticates with a per-organisation “plugin token” you paste into the plugin’s settings page (WooCommerce → WC-Manager Stock Take). No data is sent until you configure that token and use the Stock Take panel. WC-Manager’s terms and privacy policy: https://wc-manager.com/terms and https://wc-manager.com/privacy.

The REST endpoints, the Members panel, and TeraWallet/membership reads make no external requests — they only respond to authenticated requests into your own site.

Privacy

This plugin does not collect, store, or transmit personal data on its own beyond the Stock Take sync described above, which only sends the stock-count data you create to your own WC-Manager account. See https://wc-manager.com/privacy.
