What is the Fulfillment Priority when FBM is Enabled?

Users may wonder what gets prioritized by default when both FBA & FBM are enabled.

 

Amazon typically prioritizes FBA (Fulfillment by Amazon) for order fulfillment. Orders will only be routed to FBM (Fulfilled by Merchant) when FBA inventory is running low. Additionally, during peak seasons or periods of high logistical demand, Amazon may temporarily route orders to FBM to manage capacity. However, the algorithm consistently strives to prioritize FBA whenever possible, ensuring faster and more streamlined fulfillment.
