Question 1

How do pool companies bill for chemicals?

Accepted Answer

Either at cost plus 20–30% markup (shown on its own line), or a flat monthly chemical fee bundled with the visit rate. Whichever you pick, disclose it in your service agreement.

Question 2

Should pool service be invoiced monthly or per visit?

Accepted Answer

Monthly is standard — one invoice for the four weekly visits — because per-visit invoicing creates too much admin. Repairs go on the same invoice as separate lines.

Question 3

Is pool service taxable?

Accepted Answer

In many US states residential pool cleaning is taxable (Texas, Connecticut, others). In the EU it's standard-rated VAT. Check locally — some states tax the chemicals but not the labour.
