About STC
STC (Sole Trader's Companion) started because I wanted a proper way to track my own second-hand selling across Vinted, eBay and everywhere else, without handing that data to someone else's platform.
It's built around how reselling actually works: things bought cheap in batches, listed on more than one site, sold, posted, sometimes returned, and eventually turned into a tax return.
Not for sale
Your records are never sold or shared. No tracking cookies, no analytics, no third-party trackers.
Open source
AGPLv3, so the code is always there to read, and any changes to it have to stay open too.
No lock-in
Export your data and leave whenever you want, or take it to a server of your own.
Still in beta
Expect rough edges and expect things to change. Feedback shapes what comes next.
