A no-login read from sales, inventory purchases, payroll, returns, fixed bills, and your POS.
Enter the rough retail numbers you already know. The POS choice tells the demo what data pipe would light this up later.
If you only know purchase orders or vendor bills, use those as a rough COGS stand-in. Live POS/inventory data sharpens this later.
Nothing is saved. This is a quick estimate, not a full diagnosis.
