The Sample Cost Sheet

Your profit report is only as honest as your cost numbers. This page shows exactly what belongs in your landed cost per unit — and what to leave out — so SellerSocket's P&L shows your true net profit, not a comfortable fiction.

The one rule

Landed cost = everything it took to get one sellable unit into Amazon's hands. If the money left your pocket before Amazon could sell the unit, it belongs in the number. If Amazon charges it after the sale, leave it out — SellerSocket already pulls those charges from Amazon automatically, and including them would double-count.

Include (you paid to create the unit)

Supplier / manufacturing cost per unit
Inbound freight & shipping to Amazon, per unit
Customs duty and tariffs, per unit
Prep, labeling, poly-bagging
Packaging, boxes, and inserts

Spread shipment-level costs across units: a $950 freight bill on 1,000 units adds $0.95 to each.

Leave out (Amazon reports these to us)

Amazon referral fees
FBA fulfillment & storage fees
Advertising spend
Refunds and reimbursements
Your monthly software subscriptions

These land in your P&L from Amazon's own records — putting them in COGS counts them twice.

A worked example

The demo catalog, costed honestly. Each column is a real cost of getting the unit shelf-ready; the last column is the only number you give SellerSocket.

SKU	Supplier / unit	Freight / unit	Duty / unit	Prep & pack / unit	Landed cost
WIDGET-BLK-01	$4.85	$0.95	$0.29	$0.41	$6.50
WIDGET-BLU-01	$4.85	$0.95	$0.29	$0.41	$6.50
GADGET-STD-02	$3.10	$0.62	$0.19	$0.29	$4.20
GIZMO-XL-03	$8.90	$1.78	$0.53	$0.54	$11.75
SPARE-KIT-04	$1.45	$0.38	$0.09	$0.18	$2.10

Costs changed over time? Use the landed cost of the inventory you're selling now. When a new shipment lands at a new cost, just tell SellerSocket the new number — it takes thirty seconds.

Then just tell Claude

No upload, no import wizard. Once SellerSocket is connected, paste or type your costs in any format you like — Claude reads it and saves it:

// say it however you want — this works:
"Save my product costs:
WIDGET-BLK-01 and WIDGET-BLU-01 are $6.50 each,
GADGET-STD-02 is $4.20, GIZMO-XL-03 is $11.75,
SPARE-KIT-04 is $2.10.
Then show my profit for the last 30 days."

From that moment, every profit report includes a COGS line and true net profit. Ask "what costs do I have on file?" anytime to review them.
