1. Wisconsin-specific invoice requirements

  • Sales tax line: 5.00% state rate. Most services rendered in Wisconsin are exempt from sales tax — but materials, parts, and tangible goods are not. State 5%; combined commonly 5.5-6%.
  • Late-fee cap: Wisconsin statute Wis. Stat. §138.04 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.
  • Right-to-cancel notice: Customers in Wisconsin 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 Wisconsin 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.
  • Shingles / membrane — billed by itemized.
  • Labor — billed by hour (~$75 default).

3. Roofer licensing in Wisconsin

4. Send and follow up
