Divinestock: Track stock and sales on Windows — no subscription

Hey Product Hunt! I'm Divine, a developer from Zimbabwe 🇿🇼 I built DivineStock after seeing small shop owners around me losing track of stock using notebooks and memory — and unable to afford expensive cloud POS systems with monthly fees. DivineStock is a straightforward Windows desktop app: add your products, process sales, track what's running low, back up your database with one click, and control staff access via role-based logins. No internet required, no subscription — buy once and use forever. It's built with VB.NET and Microsoft Access, so it runs on virtually any Windows PC without complicated setup. I'd love feedback from anyone who's worked with small retail businesses or built tools for emerging markets — what features would make this genuinely more useful for a shop owner with limited tech experience?
