A seller moving out of a garage asks three providers what storage costs. Each quotes a rate per pallet per week, and the three are broadly similar.
She picks the cheapest. The first month's invoice is several times what she expected, because the storage line is a small fraction of it and everything else is charged per order, per item, per parcel and per return.
Nobody misled her. She asked about storage and was told about storage, and the question she needed to ask was what the whole month costs at her volumes.
What a fulfilment bill is actually made of
Six components. Goods in handling, storage, picking, packing and materials, despatch, and returns processing, plus any account or minimum charge.
Component 1: goods in
Charged per pallet, per carton or per hour to receive, check and put away stock. A one off per delivery and frequently overlooked entirely.
Component 2: storage
Per pallet, per shelf or per cubic measure, per week or per month. The number sellers ask about and usually the smallest line on the invoice.
Component 3: picking
Frequently a charge for the first item and a smaller one for each additional item. This is where order volume translates directly into cost.
Component 4: packing and materials
Labour plus the box, the filler and the label. Sellers with their own branded packaging need to establish who supplies and stores it.
Component 5: despatch
The carrier cost, which may be at the provider's negotiated rate or the seller's own account, and which is the largest line for many sellers.
Component 6: returns
Receiving, inspecting, restocking or disposing. For apparel in particular this is substantial and it is almost never in a headline quote.
A worked example at low volume
A seller with few pallets and modest order numbers finds storage is a meaningful share, and the minimum monthly charge frequently dominates everything.
The same seller at ten times the volume
Storage barely moves and the per order components multiply, so the bill is now driven almost entirely by picking, packing and despatch.
Why the comparison needs the seller's own numbers
Two quotes ranked one way at a hundred orders a month reverse at a thousand, which is why a rate card comparison is close to meaningless.
Why the peak needs stating
A seller whose volume multiplies for six weeks needs to know how that is charged and whether the provider can handle it, which is the pattern in pallet versus parcel questions from growing sellers.
Why the contract terms matter as much as the rates
Minimum terms, notice periods and what happens to stock on exit. A cheap rate on a long tie in is not cheap.
Why the integration matters
How orders reach the warehouse and how tracking comes back, since manual order transfer is a hidden cost paid in the seller's own time.
Do the arithmetic at the enquiry
An assistant that asks for order volume, items per order, storage footprint, packaging requirements, returns rate and seasonal peak can produce a monthly total rather than a rate card, which is the only figure a seller can actually compare.
