Kosha started as a tool for a small Amazon selling experiment my wife and I were planning. While preparing for it, I kept running into the same problem: product cost, GST, packaging, marketplace fees, inventory, returns, settlements, and actual profit all lived in different places or ended up becoming another complicated spreadsheet. We eventually decided not to launch the selling business at all. We never even shipped the first product. But I had already become interested in the software problem, so I kept building. Kosha became my attempt at a much simpler seller operations tool: local-first, no account, no backend, and focused on one basic question — after everything that happened to a sale, what did I actually make? It is still an early product and I don't have a user base behind it. I'm launching it here mainly to put it in front of people who understand this problem and find out what I have missed. Would particularly love feedback from marketplace sellers or anyone who has built tools for small sellers.
