Compare equipment and selected service subtotals from a written quote, or explore dated planning ranges. Monthly and annual invoices stay distinct; unknown amounts stay unknown.
Written-quote mode models selected setup paid upfront and distinct monthly or annual invoices over 12, 36 and 60 months. Confirm included lines and avoid counting bundled services twice. Annual invoices use the actual yearly amount.
Historical planning ranges are labeled with their assumption date in the tool. Confirm current written offers. Neither mode establishes complete ownership costs, financing payments, taxes, permits or future price changes.
