Great news for Amazon seller partners! Are you tired of the constant challenges in FBA shipment operations? After creating a shipment, do you find yourself repeatedly modifying estimated delivery times due to real-time factors like traffic and weather? Are delayed updates causing disruptions in supply chain planning, or even affecting your inbound performance metrics? Does frequent communication to confirm delivery times consume energy that could be spent on core business tasks?
Worry no more—these logistics pain points now have a perfect solution!
As an Amazon-authorized FIST carrier, Huayangda Logistics proudly introduces the FIST Delivery Window Automation feature. With three core advantages, we redefine efficient Amazon logistics operations, helping every seller save time, effort, and resources.
Advantage 1: Automatic Updates – Say Goodbye to Manual Work
In the past, adjusting estimated delivery windows relied on manual efforts. Sellers had to monitor real-time transit status and manually update timelines in the backend—any oversight could lead to missed updates. The FIST feature changes this: simply check the 【Allow FIST carrier to update my delivery window】 option when creating a shipment. Huayangda Logistics will use real-time Amazon FIST system data to auto-sync shipment status and accurately update delivery windows.
Advantage 2: Accurate Information – Minimize Supply Chain Risks
Outdated information has long been a hidden risk in logistics. With manual updates, delivery window details often lag, leading to mismatches in Amazon warehouse scheduling and potential hits to inbound performance metrics. The FIST feature enables seamless, real-time data integration between the platform, sellers, and carriers. Whether adjusting for delays or optimizing early arrivals, the system updates automatically, ensuring precise supply chain planning and smoother inbound transitions—protecting your store’s performance.
Advantage 3: Simplified Workflow – Focus on Growing Your Business
Previously, confirming delivery times required constant back-and-forth with carriers: “Where’s the shipment? Does the ETA need updating?” This consumed significant time and often led to miscommunication.
Now, FIST enables “silent mode” collaboration! The system auto-tracks, auto-updates, and auto-syncs—all information is transparent and accessible without extra communication. Sellers reclaim time for product selection, marketing, and customer service, while carriers focus on transportation. It’s a win-win!
Easy Setup – New or Existing Shipments
The FIST feature is user-friendly, even for beginners.
1.For New Shipments (Created after Dec 26)
Amazon’s system will default to selecting 【Allow FIST carrier to update my delivery window】．Sellers must ensure both of the following are checked:
· Under 【Delivery Window】: Check 【Allow FIST carrier to update my delivery window】
· Under 【Carrier】: Keep the default 【Non-Amazon partnered carrier】–【FIST carrier】 selected.
· Both selections are essential.
2. For Existing Shipments:
If you wish to enable the feature for in-transit or previously created shipments, you may encounter one of three scenarios. Follow the guidelines below:
Scenario 1:
The 【Allow FIST carrier to update my delivery window】 checkbox is already checked.
No action needed. Click “Cancel” to exit the editing page—the feature is already active.
Scenario 2:
The checkbox is present but unchecked.
Complete these three steps:
① Check the 【Allow FIST carrier…】 box.
② Reconfirm the original delivery window selection.
③ Click the confirmation button (red box).
Scenario 3:
The checkbox is not visible in the delivery window editing window.
Follow these steps:
Go to the final step of STA shipment creation: “Tracking Details,” and under “Carrier,” select 【Change carrier】.
On the update page, select 【Huayangda】 (the FIST carrier name) and click “Update.”
Return to the “Edit Delivery Window” page and follow the steps for Scenario 1 or 2.
