Notes on the specific mechanics of selling on Amazon: not general advice, the parts that actually trip sellers up.
Products shipping under 25 units a month are exempt. Above that, Amazon charges a returns processing fee once your return rate passes a category threshold.
Reporting lag, stock issues, and lost Featured Offer ownership explain most no-sale campaigns. Check these before pausing a keyword that was not the problem.
A plain-English guide to Amazon's Selling Partner API, OAuth authorization, what a seller app can request, and how to check whether a connection is safe.
Amazon charges this fee only when 30-day and 90-day historical days of supply both fall below 28 days, a backward-looking metric, not simple stock math.
NCX rate divides negative-experience orders by total orders, so low-volume ASINs can swing wildly. Learn how to read it before a listing gets deactivated.
A sales drop can come from less traffic, lower conversion, or a lost Featured Offer. They look identical on a revenue chart until you separate the metrics.
EcomSanity Pro runs $9.90/month, sellerboard Standard about $19, and Sellerise Starter $19.99. See which one earns its place under $20 for your business.
Sales velocity equals units sold divided by days in the period, though the window you pick and how you handle stockout days can change the number substantially.
Seller Central already provides orders, reports, inventory, and ad data for free. Paid software earns its place when it saves labor or prevents costly misses.
Fewer inbound destinations mean a higher placement fee; more destinations lower it but raise freight cost. The cheapest fee is not always cheapest overall.
Amazon can hold 500 of your units while only 320 are available to sell. Available, reserved, inbound, unfulfillable, and stranded each mean something different.
Order reports lag about 30 minutes, ad sales take hours, Brand Analytics up to 72 hours, and FBA inventory up to 24 hours. There is no single refresh time.
