Your POS shows revenue. Your accountant handles taxes. Neither tells you today's profit, the number that decides if a shop survives. Nouz is a same-day profit & loss tracker for small business owner-operators: cafés, restaurants, retail, salons, e-commerce. Log the day in ~60 seconds; nouz computes real profit after fees, cost of goods, variable costs, and a daily share of fixed overhead. Weekly and monthly trends catch a bad week before month-end. No spreadsheets, no accounting degree.
