Pool Service Billing Rules
Record Chemical Readings on Every Invoice
Always note pH (7.4-7.6), Free Chlorine (2-4 ppm), and Salinity (3200 ppm) on the bill to prove professional water balance.
Bill Monthly on the 1st in Advance
Top pool routes bill monthly service upfront on the 1st of each month rather than after the fact to prevent seasonal churn.
Itemize Salt Cell Cleanings
Muriatic acid washing of salt chlorine generator cells is an extra maintenance service that should be billed every 3 months.
Frequently Asked Questions
How do pool cleaners bill monthly accounts?
Most pool routes bill a flat monthly fee (e.g. $140/mo) covering 4 weekly visits, with specialty shock billed as separate line items.
What should be documented on a pool service receipt?
Chemical readings (pH, Chlorine, Alkalinity), chemicals added (lbs of shock, gallons of liquid chlorine), equipment checklist, and payment terms.
Is sales tax charged on pool maintenance?
In states like Florida and California, swimming pool maintenance is treated as janitorial/service and state tax rules vary on whether chemicals are taxed separately.
