WooCommerce inventory management for serious stores
WooCommerce runs your store. Celerp runs everything behind it - inventory, manufacturing, purchasing, and accounting - all synced to WooCommerce in real time.
Free, with open-source modules. Connect sync from $29/mo.
What WooCommerce inventory can't do
WooCommerce is great for selling. It wasn't designed to be your ERP.
No multi-location stock management
WooCommerce tracks a single stock count per product. Celerp gives you unlimited warehouses, bins, and locations - all synced back to your store.
No purchase orders or supplier management
When stock runs low, WooCommerce leaves you on your own. Celerp generates purchase orders, tracks deliveries, and updates stock automatically on arrival.
No manufacturing or bill of materials
If you make what you sell, WooCommerce can't track assemblies, BOMs, or production runs. Celerp handles complex manufacturing workflows.
No real accounting
WooCommerce shows revenue. Celerp tracks COGS, margins, journal entries, and your full P&L - automatically from every sale.
Connect Celerp to WooCommerce in 3 steps
Download and install Celerp
pip install celerp or download the desktop app for Mac, Windows, or Linux. Takes under 2 minutes.
Subscribe and connect WooCommerce
Start a free 14-day trial of the Celerp relay ($29/mo after trial). In Celerp, go to Connectors → WooCommerce. Enter your store URL and API keys. Products and orders sync immediately.
Your inventory stays in sync
Every sale on WooCommerce updates Celerp stock in real time. FIFO/FEFO costing and reports update automatically.
What syncs between WooCommerce and Celerp
Two-way sync keeps your store and your back office always in agreement.
WooCommerce orders pull into Celerp automatically. Stock is decremented, COGS is recorded.
Inventory changes in Celerp push back to WooCommerce. Your storefront always shows accurate availability.
Products sync by SKU. Manage variants, barcodes, and product details in one place.
WooCommerce customers sync to Celerp CRM. Track order history, contact details, and lifetime value.

Frequently asked questions
Is Celerp really free?
Yes. The Celerp desktop app is free, with a source-available core and open-source MIT modules. The Connect plan ($29/mo) adds WooCommerce syncing, encrypted backups, and secure access from anywhere for you and your team.
Will this slow down my WooCommerce store?
No. Celerp runs on your machine, not on WordPress. Sync happens in the background via REST API. Your storefront is unaffected.
Where does my data live?
On your machine. Celerp is self-hosted. Your inventory, orders, and accounting data never touch our servers unless you enable encrypted backup (encrypted with your key).
What happens if I cancel Connect?
Your Celerp keeps running exactly as before. You lose WooCommerce syncing, encrypted backup, and remote access. Your data stays yours - export it or keep using Celerp offline.
Can I use Celerp without WooCommerce?
Yes. Celerp is a full ERP with inventory, manufacturing, accounting, and CRM. The WooCommerce connector is optional - use Celerp standalone or connect it later.

Your WooCommerce store deserves a real back office.
The Celerp app is free, with a source-available core and open-source MIT modules. The WooCommerce sync connector runs through the Celerp relay at $29/mo - still a fraction of what TradeGecko ($159/mo) or Brightpearl ($299/mo) charges.
