Most of the time, it comes down to when you want to pack your boxes.
- In PRIVATE, you would pack the boxes when you are completely finished scanning all of your items and ready to finish the batch and start the shipping process. InventoryLab does provide *tentative* destinations that you can see as you are listing to try and pre-sort, but we don't have any control over what Amazon decides as the final fulfillment centers. Especially in Q4, this can vary greatly.
This happens because as you are scanning, Amazon is only getting a portion of the product information through the feeds. They don't receive the full information until you are finished scanning your items and ask to create a shipment plan, but you usually will have fewer fulfillment centers assigned to ship to.
- In LIVE, you would pack as you are scanning. Your items will be assigned a final fulfillment center as you go along.
This happens because we are sending the full product feed information to Amazon. However, people tend to get more fulfillment centers assigned.
Your preference as to when you would like to pack them will probably be your deciding factor.
The best part is - if you don't like the way you chose, you can always close the batch and start in the other workflow ;)
