How Much Does an FBA Prep Center Cost? 2026 Pricing Guide

Most FBA prep centers charge between $0.50 and $3.00 per unit for standard prep services. The exact cost depends on the complexity of the prep work required. Simple FNSKU labeling may cost $0.20-$0.50 per unit, while full prep including poly bagging, labeling, and inspection typically runs $0.75-$2.00 per unit. Bundling and kitting adds $0.50-$2.00 per bundle on top of base prep fees.

Per-unit pricing is the most cost-effective model for most sellers because you only pay for exactly what you use. At low volumes (under 500 units/month), per-unit pricing avoids the overhead of flat monthly fees. At higher volumes (5,000+ units/month), per-unit models also tend to offer the best value because volume discounts reduce your effective rate. Flat monthly fees only make sense at very high volumes (10,000+ units) where the fixed cost is spread across enough units to beat per-unit rates.

Yes, most prep centers charge storage fees separately from prep fees. Typical rates range from $20-$50 per pallet per month. Some centers offer a brief free storage window (7-14 days) while your inventory is being prepped, then begin charging daily or monthly storage rates. Always clarify storage terms upfront — slow-moving inventory fees can add up quickly.

Common hidden fees include account setup fees ($50-$200), minimum monthly charges ($100-$500/month regardless of volume), slow-moving inventory surcharges, special handling fees for oversized or fragile items, rush processing premiums (25-50% extra), and return-to-sender fees. Always request a complete fee schedule before signing up and ask specifically about these categories.

Volume discounts at FBA prep centers typically reduce your per-unit cost by 15-40% as you scale. At 500 units/month, expect roughly 10-15% off standard rates. At 1,000 units, discounts reach 15-25%. At 5,000+ units, many prep centers offer 25-40% off their published per-unit rates. The savings compound across all services — labeling, poly bagging, storage, and shipping.

At under 200-300 units per month, self-prep is usually cheaper in direct costs alone — roughly $0.10-$0.30 per unit for supplies. But once you factor in your time at $25-$50/hour, equipment costs ($500-$2,000 startup), error-related Amazon fees, and opportunity cost, most sellers break even with a prep center around 300-500 units/month. Above that threshold, a prep center almost always saves money when total cost is considered.

Outbound shipping from a prep center to Amazon fulfillment centers typically costs $0.30-$0.80 per unit for standard-size items via partnered carrier programs. The exact cost depends on carton weight, distance to the assigned fulfillment center, and whether you use SPD (small parcel) or LTL (less than truckload) shipping. Prep centers with daily standing appointments at Amazon FCs often get better rates due to volume.

Receiving fees at FBA prep centers typically range from $25-$50 per shipment for standard deliveries. This covers unloading, counting, inspecting for damage, and checking inventory into the warehouse management system. Some centers charge per-pallet receiving fees ($15-$35/pallet) instead of per-shipment. Oversized or freight deliveries may incur additional handling fees of $50-$100.
