A $35 sale does not mean $35 in your pocket

A $35 sale does not mean $35 in your pocket
By the time Amazon takes its cut
that number gets smaller fast
The referral fee runs around 15%
FBA fulfillment takes another slice
Storage
Returns
And the long term inventory penalties
nobody reads about until they hit
Most sellers track the wrong number
They watch top line revenue climb and feel rich
Then they check the bank account and feel confused
Revenue tells you nothing about whether the business actually works
Returns get charged twice
You eat the fulfillment cost going out
and the processing cost coming back
even on a return you did not cause
PPC quietly eats margin
When your TACoS climbs higher
than your net margin
Every ad driven sale costs you money to make
You are not buying growth at that point
You are buying losses with a nicer dashboard
Storage fees compound
Slow movers sitting in a warehouse during Q4
get hit with aged inventory surcharges
that turn a profitable SKU into a liability
Sellers who scale know their true net margin per SKU
Sellers who stall know their revenue
and nothing underneath it
Run the math on your worst performer today
Take the sale price
Subtract referral fee
fulfillment
product cost
returns
Ad spend allocated to that listing
If what is left is thin or negative
You do not have a sales problem
You have a profit leak
Revenue feeds your ego
Profit feeds your business
