BigCommerce UPS Integration
Nventory bridges BigCommerce and UPS by importing orders into a central dashboard, syncing product data like weights and dimensions, and pushing UPS tracking information back to BigCommerce 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, BigCommerce's native tools, or a dedicated shipping solution. Nventory syncs order data and tracking info but does not create labels directly.
Rate calculation for BigCommerce checkout requires BigCommerce's native carrier quote engine or direct UPS API integration. Nventory focuses on order and product data sync.
The real-time carrier quote engine depends on complete product data. Missing weights or dimensions lead to inaccurate rate displays at checkout.
Things to Consider
Platform-specific details and how they affect this integration.
BigCommerce supports real-time UPS carrier quotes natively. Connecting your own UPS account ensures checkout rates reflect your negotiated discounts rather than retail pricing.
Nventory does not manage UPS account connections for checkout quotes. It complements BigCommerce's native carrier quotes by providing centralized order management, product data sync, and tracking updates.

Frequently Asked Questions
No. Nventory does not generate labels directly. It syncs order and product data and pushes UPS tracking numbers back to BigCommerce after shipments are created through your preferred label solution.
No. BigCommerce has built-in UPS carrier quote support for checkout. Nventory complements this by providing centralized order management, product data sync, and tracking updates across channels.
After shipments are created in UPS, tracking numbers sync to BigCommerce through Nventory, updating the order status and triggering customer notification emails.
Yes. Nventory imports orders from BigCommerce and other sales channels into a single dashboard, giving you a unified view of all orders and their UPS tracking status.
After a shipment is created in UPS, Nventory pushes the tracking number to the corresponding BigCommerce order, updating the order status and triggering customer notification emails. 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. BigCommerce has a built-in carrier quote engine that supports UPS rates at checkout. Nventory complements this by ensuring accurate product weights and dimensions are synced from BigCommerce so both the checkout rate display and your fulfillment label tool have correct data for UPS Ground, UPS SurePost, and other service-level comparisons.
Check that the import/export field mapping between BigCommerce and UPS WorldShip is correctly configured, as mismatched fields (such as address line order or phone number format) will cause import failures. For batch processing errors, reduce the batch size and verify that no individual orders contain special characters or excessively long field values that WorldShip cannot parse. If you experience connection timeouts, adjust the timeout settings in WorldShip's import configuration and ensure your network allows outbound connections to BigCommerce's API endpoints.
