Hi Product Hunt! 👋

I built StockFlow because most POS systems force small business owners into expensive monthly subscriptions and bloated database setups.

StockFlow is a complete, lightweight POS and inventory system built with Node.js and SQLite. It runs with zero database setup, works offline, includes integer-precision profit tracking, and features a built-in help assistant with zero API costs.
