Power and gas price simulator · formerly PREZZATORE
BILLY rebuilds the power or gas bill of a customer or prospect and applies your supply company's offers to compare them. It uses the same calculation logic as ARERA and also works as a widget on the company website.
Features
Clear proposals, savings that show up on the invoice. Comparing different offers means considering every item on the bill, not just the commodity. BILLY calculates the full monthly cost of supply, so the sales network presents real savings and customers can check them themselves, including on the website.
