What every water treatment invoice needs

  • Your business name, address, phone and license number
  • Invoice number, date and due date
  • Customer name, billing address and service address
  • A line for every service, part and fee, with quantity and rate
  • Tax, total, payments received and balance due
  • Payment terms and how to pay

Pricing water treatment work

  • Price equipment from your cost plus installation hours at your loaded rate, plus margin, and know the margin each product line earns.
  • Price rentals so the monthly fee covers the equipment cost over a realistic life, service visits, consumables, and margin. Set a clear buyout formula if you offer rent-to-own.
  • Price salt delivery per bag or per delivery with a delivery fee, and set a minimum so small deliveries cover the stop.
  • Bundle filter and membrane changes into a subscription priced at the replacement interval, with the visit included.
