  "problem": "RMH3 Dental sells on Net32, eBay, Amazon, Shopify and Walmart, plus direct orders by phone and email. The business ran on off-the-shelf ERP software, a dozen spreadsheets and a shared inbox someone sorted by hand. Every job needed a second tool to finish, the systems disagreed about stock and money, and nobody could say which one was right. Orders were growing and the people weren't.",
  "unique": "I stopped treating it as a dashboard over the data and built it as the place the work actually happens: the order is picked in the page, the return is decided in the page, the bill is matched in the page. Everything hangs off seven daily loops the business runs on — intake, inventory, repricing, service, returns, financials and intelligence — and every job, page and background producer has to trace to one of them. Rules that had cost real money became rules in code.",
