I built a free ERP for craft breweries — here's what I learned

Started because a friend's brewery was managing everything in Excel. Built BrewERP over the past year — fermentation batch tracking, FEFO inventory for hops/malt, PDF invoices, P&L reports, mobile PWA.

Just launched publicly at brewerp.top. Free tier available.

Happy to share tech stack or answer questions about building SaaS for niche B2B markets.
