Revenue model

Service contracts billed under multiple pricing structures: monthly fixed-price (fixed fee per contract term), square-foot (fixed monthly fee based on area serviced), cost-plus (reimbursement of labor, benefits, taxes, and insurance plus a profit margin), hourly (fixed rate per labor hour), transaction-price (fixed fee per transaction such as wheelchair passengers served or airplane cabins cleaned), and parking management fees (management reimbursement, leased location, or allowance arrangements). Supplemental work orders for non-recurring services such as flood cleanup and snow removal generate additional transactional revenue.
