Inbound Placement Service Fee
Also known as: IPSF, Placement Fee
The per-unit fee Amazon charges for routing your inbound shipment to fewer fulfillment centers (or to none, with AWD).
Inbound Placement Service Fee (IPSF) is the fee Amazon introduced in 2024 to charge sellers for the convenience of shipping to a single fulfillment center instead of splitting their inbound across multiple FCs at Amazon's discretion. The default behavior is "minimal shipment splits" where Amazon may split your inbound across 3+ destinations — the IPSF varies based on how few destinations you choose.
The three placement options: (1) Minimal Shipment Splits — lowest IPSF, but Amazon decides destinations and may split heavily; (2) Optimized Placement — medium IPSF, fewer splits; (3) Single Destination — highest IPSF, ship to one destination. AWD bypasses the IPSF entirely because the inventory enters the FBA network from the AWD facility, not from outside.
For multi-SKU shipments, IPSF can add 5-15% to total inbound cost. SellerVault's placement intelligence calculates which placement strategy minimizes total cost (IPSF + freight + AWD storage if applicable) and surfaces the recommendation directly in the shipment wizard.
