How to Choose the Best FBA Prep Center: A Complete Guide for Amazon Sellers
FBA prep centers handle labeling, poly bagging, bubble wrapping, bundling, and compliance to meet Amazon's strict inbound requirements. With Amazon's 2026 prep service elimination, a compliant prep center keeps you out of two separate fee buckets: unplanned prep and prep defect fees on non compliant units, and inbound defect fees of $0.32 to $5.72 per unit on shipments that arrive misrouted, deleted or abandoned.
Prep Center Pricing Models
Per-unit pricing runs $0.40 to $1.50 per item depending on scope, and it scales linearly with volume. Full service, meaning receive, count, inspect, FNSKU label and ship, typically lands at $0.75 to $1.50 per unit. Flat-fee models bill $3 per carton or $20 to $25 per pallet. Tiered subscriptions reduce costs for 5,000+ monthly units.
