Top Opportunities
Critical · Quick Win
Drop to "Standard Large" tier by trimming 0.3" off longest dimension
$1.13per unit
Your longest side is 10.2" — current Large tier. Reduce to 9.9" and you drop into Standard Large lower band. Achievable by switching from corrugated insert to molded foam.
Action: Replace 0.4" corrugated insert with 0.1" die-cut foam. Same protection, smaller box. Estimated factory cost increase: $0.06/unit. Net savings: $1.07/unit.
Critical
Switch from Minimal Shipment Splits to Amazon Optimized for inbound placement
$0.41per unit
You're currently sending all units to a single FC. Switching to Amazon-Optimized splits 4 ways and reduces inbound placement fees by 38%.
Action: In Send to Amazon, choose "Amazon-Optimized Shipment Splits". Free placement on most lanes; small surcharge on others. Net savings vs. minimal: $0.41/unit on average.
Important
Avoid Low-Inventory-Level (LIVE) fee — restock 8 days earlier
$0.18per unit
3 of last 6 months your Days of Supply dropped below 28 days, triggering a $0.32/unit LIVE fee on 33% of orders.
Action: Move reorder trigger from 35 days to 43 days of supply. Avoids LIVE entirely. Slight working-capital cost trade-off — but the fee waiver is bigger. Net savings: $0.18/unit blended.
Important
Q4 storage fees: pull 240 units 3 weeks earlier
$0.07per unit
Q4 storage rate jumps from $0.78/cu.ft to $2.40/cu.ft for Oct-Dec. Your Q3 sell-through forecast has 240 surplus units sitting through October.
Action: Tighten Q3 reorder qty by 240 units. Run a 10% promo at end of September to clear surplus before Q4 rates hit.
Nice to have
Drop secondary box (master carton not needed for unit FBA)
$0.03per unit
Each unit ships in primary retail box + secondary kraft outer. Amazon doesn't require the second layer for FBA. Removing it saves materials, weight (-0.04 lb), and inbound shipping density.
