Shopify UPS Integration
Nventory bridges Shopify and UPS by importing orders into a central dashboard, syncing product data like weights and dimensions, and pushing tracking information back to Shopify once shipments are created in UPS.
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 require direct integration with UPS APIs or Shopify's carrier-calculated shipping feature. Nventory focuses on order and product data sync rather than rate computation.
SurePost is not available on all UPS accounts. You must have a SurePost contract with UPS before the service is available in your fulfillment workflow.
UPS is migrating from XML to REST APIs. Existing XML credentials will eventually sunset, and merchants may need to re-authenticate their UPS account.
Things to Consider
Platform-specific details and how they affect this integration.
SurePost hands off to USPS for last-mile delivery at lower cost but adds 1-2 transit days and reduces tracking visibility after the handoff.
Nventory syncs tracking data regardless of UPS service level. After a SurePost handoff to USPS, tracking granularity may decrease but Nventory will still push available status updates to Shopify.
Who Uses Shopify UPS Integration
Common scenarios for connecting Shopify and UPS.
How It Works
Nventory sits between your platforms and keeps everything in sync.
Order Import from Shopify
Unfulfilled orders flow into Nventory with line-item weights, dimensions, and shipping addresses for centralized management.
Fulfillment Management
Review and manage orders in Nventory's dashboard. Product data including weights and dimensions 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 Synced to Shopify
Once shipments are created in UPS, tracking numbers and estimated delivery dates push back to Shopify through Nventory, marking orders fulfilled and notifying customers.
Frequently Asked Questions
No. Nventory does not generate labels directly. It syncs order and product data between Shopify and your fulfillment workflow, and pushes tracking numbers back to Shopify after shipments are created through UPS WorldShip or another label solution.
No. Rate calculation is handled by UPS APIs or Shopify's carrier-calculated shipping feature. Nventory ensures accurate product weights and dimensions are synced so that rate calculations in other tools are based on correct data.
After a shipment is created in UPS, tracking numbers sync to Shopify through Nventory, marking the order as fulfilled and triggering customer notification emails.
Yes. Nventory imports orders from Shopify and other sales channels into a single dashboard, giving you a unified view of all orders that need UPS fulfillment along with their tracking status.
Once a shipment is created in UPS, Nventory picks up the tracking number and pushes it to the corresponding Shopify order, marking it as fulfilled. For UPS SurePost shipments that hand off to USPS for last-mile delivery, tracking updates may become less granular after the handoff, but Nventory still syncs whatever status UPS provides back to Shopify.
No. Nventory does not perform rate shopping or compare carrier rates. Rate comparison requires direct integration with UPS APIs and other carrier APIs through a multi-carrier shipping tool. Nventory ensures accurate product weights and dimensions are synced from Shopify so that whichever rate-shopping tool you use has correct data for UPS Ground, UPS SurePost, and other service-level comparisons.
Begin by confirming that your UPS account credentials are valid and that the account is in good standing, as expired agreements or suspended accounts will silently block label creation. Next, check for address verification errors by reviewing the destination address against UPS standards — incomplete apartment numbers, mismatched ZIP codes, or unsupported territories are common causes. Also verify that the requested UPS service level is available for the origin-destination zone, since not all services are offered in every region.
