WooCommerce UPS Integration
Nventory bridges WooCommerce and UPS by importing orders into a central dashboard, syncing product data like weights and dimensions, and pushing UPS tracking information back to WooCommerce orders.
Sync Matrix
4 data entities in the sync matrix — 1 bidirectional, 3 one-way. Tap any row for details.
Good to Know
Platform restrictions outside any integration tool's control
Label generation must be done through UPS WorldShip, UPS APIs, or a dedicated shipping label solution. Nventory syncs the order data and tracking info but does not create labels directly.
Real-time rate calculations for WooCommerce checkout require direct UPS API integration or a WooCommerce shipping plugin. Nventory focuses on order and product data sync.
SurePost is not available on all UPS accounts. You need an active SurePost contract before the service is available in your shipping workflow.
UPS is migrating from XML to REST APIs. Existing XML credentials will sunset, and merchants may need to update their UPS account connection.
Things to Consider
Platform-specific details and how they affect this integration.
WooCommerce UPS plugins handle checkout rates and label generation. Nventory serves a different purpose — centralized order management, product data sync, and tracking sync.
Nventory complements your existing UPS shipping plugin or label solution by providing centralized order management, accurate product data sync, and tracking updates across multiple channels.
Who Uses WooCommerce UPS Integration
Common scenarios for connecting WooCommerce and UPS.
How It Works
Nventory sits between your platforms and keeps everything in sync.
Order Intake from WooCommerce
New WooCommerce orders sync to Nventory with line items, product weights, shipping class data, and customer addresses.
Fulfillment Management
Review and manage orders in Nventory's dashboard. Product data including weights, dimensions, and shipping classes is available for your shipping workflow.
Ship via UPS
Create shipments and labels through UPS WorldShip or your preferred shipping tool using the accurate product data synced by Nventory.
Tracking Sync & Customer Notification
UPS tracking numbers push to WooCommerce through Nventory, marking orders as shipped and sending branded notification emails to customers.
Frequently Asked Questions
No. Nventory does not generate labels directly. It syncs order and product data between WooCommerce and your fulfillment workflow, and pushes UPS tracking numbers back to WooCommerce after shipments are created.
No. Nventory complements shipping plugins by providing centralized order management, product data sync, and tracking updates. Your UPS shipping plugin or label solution handles rates and label generation.
After shipments are created in UPS, tracking numbers sync to WooCommerce through Nventory, updating the order status and triggering your existing WooCommerce notification emails.
Yes. Recurring subscription orders sync to Nventory like any other order, and UPS tracking is pushed back to WooCommerce after shipments are created in your shipping tool.
After a shipment is created in UPS, Nventory pushes the tracking number to the corresponding WooCommerce order, updating the order status and triggering WooCommerce's customer notification email. For UPS SurePost shipments that hand off to USPS for last-mile delivery, Nventory still syncs the UPS tracking number, though scan events may become less granular after the USPS handoff.
No. Nventory does not perform rate shopping or compare carrier services. Rate comparison between UPS Ground, UPS SurePost, and other UPS service levels requires a WooCommerce UPS shipping plugin or a multi-carrier shipping tool with direct UPS API integration. Nventory ensures accurate product weights, dimensions, and shipping class data are synced from WooCommerce so your rate tool has correct data.
Enable the UPS Address Validation API in your shipping plugin settings to catch errors before label creation — this validates street addresses, city/state/ZIP combinations, and residential vs. commercial classification. For international orders, ensure addresses follow the destination country's formatting conventions, as UPS is strict about field order and character limits. Note that UPS does not deliver to P.O. Boxes, so orders with P.O. Box addresses must be rerouted to an alternative carrier like USPS or flagged for manual review in WooCommerce.
