The service, tiers, and prices below are fictional. When this gets built for a real business, every number comes from their own published pricing, the way the example below shows.
How this gets built for real
Only the pricing a business already publishes. This doesn't invent numbers, it turns a printed price list or tier table into something a customer can combine themselves.
It calculates, it doesn't book. The honest next step after a number is still the business's real quote or booking process, this just gets someone there already knowing what to expect.
