1. Arizona-specific invoice requirements
- Sales tax line: 5.60% state rate. Most services rendered in Arizona are exempt from sales tax — but materials, parts, and tangible goods are not. TPT (transaction privilege tax) of 5.6%; combined commonly 8-11%.
- 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.
2. Roofer line items + standard terms
Every roofer invoice in Arizona should itemize work clearly. Standard roofers use Net 14 terms with a 33% deposit required upfront.
- Tear-off — billed by flat.
- Underlayment — billed by itemized.

3. Roofer licensing in Arizona
Most states require a roofing-specific or general contractor license. Manufacturer warranty often requires certified installer.
4. Send and follow up
Send the invoice the same day work completes. Use software that records open events and offers a one-click online payment so you don't need to chase a check by mail. Arizona customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
