I built a SaaS for small business inventory management — here's what I learned launching it

Hey! I'm Ibrahim. I spent the last several months building StockAlert (onlinestockalert.com), a stock management tool for small businesses — retail shops, restaurants, bakeries, cafés. Why I built it: Small business owners kept losing money from stockouts and late reorders. They either used Excel or nothing at all. I wanted something simple that actually sends alerts and lets you reorder from suppliers in one click. What I shipped: Automatic low-stock alerts One-click supplier orders via WhatsApp, PDF, or Email Restaurant mode with recipe & portion tracking POS integration (Stripe + Square) Multilingual: FR / EN / NL My biggest launch lessons so far: Don't wait for "perfect" — bugs will find you in production anyway Unit mismatches (kg vs g) can silently break core features — test edge cases early Environment variables in production will humble you 😅 Would love feedback on the product or the positioning. Anyone else building for brick-and-mortar businesses?
