What do the maintenance fees add up to?

Use annual contract fees. The example is 20 buildings at $800 per year, with two scheduled visits. Repairs are separate.

Buildings under agreementAnnual fee per building ($)Scheduled visits per building per yearSeparately expected repair sales for this group ($/year)Direct annual delivery costs for this group ($)Include crew labor, materials, travel and any direct subcontract cost.

Fees = buildings x annual fee. Visits = buildings x visits per year. Fees plus repair sales minus direct delivery costs leaves an amount before marketing and overhead. Replacements you hope to win aren't recurring contract income. This tool doesn't send or store your inputs.
