Key cost components in fulfillment
A 3PL or fulfillment center bill is rarely a single line item. It's built from five moving parts, and knowing how each is priced is what lets you actually control your cost per order instead of just watching the invoice total.
- Storage Fees — charges for holding your inventory in a warehouse, typically calculated per cubic foot or pallet per month.
- Pick and Pack — the labor and material cost to locate items on shelves and box them for delivery.
- Shipping/Postage — the carrier rate determined by the weight, dimensions and destination of the final package.
- Inbound Receiving — fees for unloading and cataloging incoming shipments from your manufacturer.
- Returns Processing — costs associated with inspecting and restocking returned customer items.
The formula
Storage Fees = cubic feet stored × storage rate
Pick & Pack = orders × pick & pack rate
Shipping/Postage = orders × shipping rate
Inbound Receiving = units received × receiving rate
Returns Processing = (orders × return rate%) × returns fee
Total Fulfillment Cost = sum of all five
Cost Per Order = Total Fulfillment Cost ÷ orders
Pick & Pack = orders × pick & pack rate
Shipping/Postage = orders × shipping rate
Inbound Receiving = units received × receiving rate
Returns Processing = (orders × return rate%) × returns fee
Total Fulfillment Cost = sum of all five
Cost Per Order = Total Fulfillment Cost ÷ orders
Worked example
You ship 500 orders a month, storing 100 cu ft at $0.75/cu ft ($75), with pick & pack at $3.25/order (500 × 3.25 = $1,625) and shipping at $6.50/order (500 × 6.50 = $3,250). Receiving 600 units at $0.35/unit adds $210, and a 5% return rate (25 returns) at $4.00 each adds $100. Total: 75 + 1,625 + 3,250 + 210 + 100 = $5,260, or about $10.52 per order.
