Who writes this

I spent about two years inside marketplace operations before starting this site. At Parknes Inc., a US-based e-commerce and third-party fulfillment company, I handled listing, category and content management across Amazon, Walmart and eBay, and worked on shipment planning, carrier tracking and stock movement on the logistics side. I then founded and ran my own e-commerce venture for a year, from company setup through sourcing, pricing and profitability reporting. I write here about the parts of that work that are hardest to find honest information on.

What I do not claim

I am not a tax adviser, an accountant or a lawyer, and nothing here is professional advice. I do not currently operate the seller accounts described above, so figures drawn from that period are labeled with the period they cover rather than presented as current. Where a number is not mine, it is cited.

Why this site exists

Marketplace fee content has a specific failure mode. A number gets published without a date, another site repeats it, and eighteen months later sellers are pricing against a rate that no longer exists. During research for the guides here, four different published estimates were found for the same policy change — every one of them from a company selling the software that solves it.

This site exists to do the boring part: go to the primary source, write down the date, name the publisher of every secondary figure, and say so when the sources disagree instead of picking one.Every figure here is cited to a source with the date it was retrieved. Where a figure comes from operations the author worked on directly, it is labeled as first-party and the period it covers is stated. Nothing is published without one or the other.

What that means in practice is set out on the method page and the editorial standards page, including a plain statement of which of the two sourcing routes each guide currently uses.
