Adding more stock to an existing product used to mean editing the quantity field — no record of who supplied it, when it arrived, what you paid. The new stock-receipt flow on every product detail page captures the supplier, the unit cost, the receipt date, and the source-of-funds account in one form. The product's stock quantity bumps automatically.

The product detail page at /business/products/<id> is now a real page — current stock, total receipts, last sale, the full stock-receipt history, the barcode, and a quick restock button. Operators stop scrolling through the master list to figure out what's happening with a single SKU.
