- Late-fee cap: Arizona statute Ariz. Rev. Stat. §44-1201 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
- Written contract required: Arizona requires a signed agreement for any job over $1,000. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Arizona get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
