Northwind Finds

Resale listing & secondhand selling tools

About Northwind Finds

Small, honest tools for the market-stall side of the internet.

What it is

Northwind Finds is a set of free tools for people who buy secondhand and sell it on: thrifters, flea-market regulars, wardrobe clear-outs and small vintage shops. They cover the jobs around each sale: working out what it really earns, writing the listing, grading the condition, measuring the piece and keeping track of stock.

How it works

Everything runs in your browser. Nothing you type is sent to a server. The price log and any fee sets you save are kept in your browser's local storage on your device; the privacy page lists exactly what is stored.

What it is not

Northwind Finds is not a marketplace and is not connected to one. It does not know any platform's current fees or rules: you enter the numbers, and you should check your platform's own pages for its fees and listing policies. The results are estimates, not financial or tax advice. The condition scale is our own, written for clarity; it is not an official standard.
