Inbound Shipment Plan (FBA)

What an FBA Inbound Shipment Plan Does

An FBA inbound shipment plan is the document Amazon generates inside the Send to Amazon workflow when a seller declares what they intend to send to FBA. The FBA inbound shipment plan lists every ASIN and quantity, the ship-from address, packaging type (individual cases or pallets), carrier, and box-level dimensions. Amazon uses the plan to assign one or more destination fulfillment centers and to issue shipment IDs (FBA followed by 10 alphanumeric characters).

You cannot ship inventory to FBA without an active inbound shipment plan. Without it, the boxes have no FBA tracking labels, no destination, and no expected receive date. Plans stay in working status for up to 30 days. Once you confirm and ship, the plan converts into one or more live FBA shipments with their own ARRIVING, CHECKED IN, RECEIVING, and CLOSED statuses.

FBA Inbound Shipment Plan Fees and Splits

The plan determines two big cost variables: where Amazon sends your boxes and which inbound services apply. By default, Amazon may split a single plan into 2 to 6 separate shipments destined for different fulfillment centers (see shipment splitting). To consolidate, sellers can opt into Amazon Inbound Placement Service, which costs $0.21 to $1.40 per unit depending on size tier. Sellers can also enroll in AWD to ship one big load to a single AWD facility, then let Amazon redistribute to FBA on demand.

Worked Example: 1,200 Unit Inbound Shipment Plan

You are reordering 1,200 units of a $32 ASIN at 8 oz per unit (small standard size tier). Manufactured in Vietnam, prepped at a US 3PL, ready to ship.

If you opted into Inbound Placement Service to consolidate to one FC, the additional fee at small standard tier ($0.27 per unit) would add $324 but save freight cost differential. Net: usually break-even or slight loss for small standard, win for oversize.

Why the Inbound Shipment Plan Matters for FBA Sellers

The FBA inbound shipment plan is where you lock in costs for the entire shipment cycle. Get it wrong and you pay for repeated label changes, manual receive corrections, and freight reroutes. Sellers running 5,000+ units per month treat the inbound shipment plan as a critical operating document and reconcile it against the manufacturer packing list before any pallet leaves the 3PL.

The plan also determines your restock limit consumption. Every unit on the plan counts against your storage tier limit the moment Amazon issues the shipment ID, even before the inventory arrives. If you have 8,000 units of restock headroom and create a plan for 9,000 units, Amazon rejects the plan with an error.

Common Mistakes with the FBA Inbound Shipment Plan

Skipping box content information. If you do not provide box-level content (which SKU and quantity is in each box), Amazon charges $0.16 per unit at receive. On a 1,200 unit shipment that is $192. Always provide box content via the Send to Amazon flow or via 2D barcode.

Mismatched packing list and plan quantities. If you ship 240 cases but the plan says 200, Amazon receives 200 and the extra 40 sit in unfulfillable inventory until you submit a discrepancy claim. The fix is a pre-ship audit comparing your 3PL packing slip to the inbound shipment plan line by line.

Reusing old shipment IDs. An expired or closed FBA shipment ID cannot be reused. Sellers who reprint old box labels send boxes with invalid IDs and Amazon refuses receipt at the dock.
