Fees and real margin
What each fee actually costs, why Seller Central's sales figure is not your profit, and how VAT lands on the whole thing. Pairs with Performance and the FBA calculator.
Straight answers to the things sellers actually search.
Not a blog. There is no posting schedule to keep and nothing here is written to fill one. Each page answers one question a UK Amazon seller has typed into a search box, in as few words as the answer honestly takes, and gets updated when the answer changes rather than when the calendar says so.
No sign-up, no email wall. Every page here is readable without an account.
What gets covered
Five areas, and the questions that come with each.
The Buy Box
How it is decided, why you lost it, and how to set a floor and ceiling you will not regret at 2am. Pairs with Repricing.
Barcodes and labelling
ASIN, SKU, FNSKU and EAN without the hand-waving, plus box content and prep requirements that decide whether a shipment is received cleanly. Pairs with Workflows.
Sourcing arithmetic
ROI against margin, what a supplier list has to clear to be worth buying, and the costs people leave out until the stock arrives. Pairs with Scout.
Catalogue hygiene
Why listings go missing from reports, where cost of goods has to live for the numbers to mean anything. Pairs with Catalogue.
Written by people who ship it
Every page here is written against software that talks to Amazon's Selling Partner API daily. Where we are unsure, the page says so and points at Seller Central rather than guessing on your behalf.
