Your FBM delivery promises have been lying to customers.
Amazon just updated shipping settings to actually work for multi-warehouse fulfillment.
If you've been managing multiple ship-from locations and trying to configure delivery promises that reflect which warehouse is closest to the buyer, you've hit the limit of what the old system could do. Everything defaulted to your primary location. Cut-off times apply globally. Delivery promises didn't adjust based on where the inventory actually sat.
That changed.
Amazon added location-based shipping settings. You can now configure order fulfillment settings:
• Operating days
• Cut-off times
• Carrier pick-up times per location, carrier, and day of the week
If you have three warehouses (California, Texas, Florida), and a buyer in Miami places an order, Amazon can now calculate the delivery promise based on your Florida warehouse's fulfillment capabilities, not your default California address.
If you're using Shipping Settings Automation (SSA), the promised delivery date gets calculated using the buyer's location, an eligible fulfillment location with inventory, up-to-date carrier delivery times, and location-specific cut-off times.
If you're still using manual transit times, the system defaults to your primary location's settings for all orders. You can't configure per-location cut-offs unless you upgrade to SSA.
For Seller Fulfilled Prime sellers, you can now set carrier-specific cut-off times and last pick-up times per location. You still need at least one weekend delivery day enabled.
The old system treated all locations as if they operated the same way. Same cut-off times. Same operating days. Same carrier capabilities.
The new system lets you reflect reality: West Coast warehouse ships Monday-Saturday with a 3 PM cut-off. East Coast warehouse ships Sunday-Friday with a 5 PM cut-off.
This matters if you've been losing conversions because your delivery promise didn't reflect your actual fulfillment speed from the closest warehouse. Buyers see "5-7 days" when you could deliver in 2-3 from a regional center. That gap costs sales.
There's no limit to the number of locations you can create. You assign SKUs to shipping templates. The system evaluates buyer location, inventory availability, and location configuration to select the optimal fulfillment location.
If you're not using SSA yet, you'll need to enable it on your shipping templates to access per-location configuration. Edit your template, enable Shipping Settings Automation, add your locations, configure carrier services.
The shift is from managing fulfillment settings at the account level to managing them at the infrastructure level. If you operate multiple warehouses, your delivery promise should reflect which warehouse is actually fulfilling the order. Now it can.
