SF International
The reviews are strongly negative and focus on reliability problems with the SF Express app. A major complaint is that authentication between Shopify and IUOP breaks repeatedly, which stops orders from syncing into IUOP and prevents tracking information from syncing back to Shopify. One reviewer also says the advertised Sync Order button does not work, and that the app only functions again after uninstalling, reinstalling, and reauthenticating it, which is not practical for daily operations. Another review, written in Chinese, says the app simply cannot successfully send back courier/shipping orders, reinforcing the same core issue: failed order synchronization. Despite the negative feedback, the reviews do provide a clear picture of what users need from the app: stable authentication, dependable order syncing, and accurate tracking updates. The main positive note is indirect: when the app is manually reset through a lengthy workaround, it can temporarily resume syncing and return tracking data to Shopify. However, this temporary success is outweighed by the recurring failures, manual effort, and operational disruption caused by the app’s instability.

I’ve been experiencing ongoing issues with the SF Express app and wanted to share my feedback in hopes it can be addressed. The app does not appear to handle authentication properly, leading to frequent disruptions. Over time, the authentication between Shopify and IUOP breaks, which prevents orders from syncing into IUOP and tracking information from syncing back to Shopify. Additionally, the Sync Order button in IUOP, which is advertised on the app’s Shopify page, does not function as intended. This issue is highlighted by other users as well in their feedback. Steps I Took to Fix It temporary: 1. Deleted the authentication in IUOP. 2. Reassigned all open orders previously assigned to the SF Express location to another location in Shopify. 3. Set SF Express inventory to zero and removed the location entirely. 4. Uninstalled and then reinstalled the SF Express app. 5. Reauthenticated the app with IUOP. 6. Reassigned the SF Express location to all products. 7. Updated inventory levels for products. 8. Placed a test order and manually assigned it to the SF Express location. 9. Fulfilled the order through IUOP, which successfully synced the tracking information back to Shopify. These steps resolved the issue temporarily. However, it’s clear this is not a sustainable solution. This app requires frequent manual reinstallation and reauthentication to maintain functionality. This is not feasible for daily operations, as it causes significant delays and additional workload. If this issue is not resolved, Store owners will need to manually import tracking numbers for all orders, or we’ll be forced to repeat these cumbersome steps daily. Please investigate and fix the underlying issue with authentication and ensure the Sync Order button functions correctly. DO NOT BLAME SHOPIFY FOR THIS.
