1. Illinois-specific invoice requirements
- Sales tax line: 6.25% state rate. Most services rendered in Illinois are exempt from sales tax — but materials, parts, and tangible goods are not. Services largely exempt; combined rates up to ~11% in Chicago.
- Late-fee cap: Illinois statute 815 ILCS 205/4 (Interest Act) 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: Illinois requires a signed agreement for any job over $1,000. Reference the contract number on the invoice.
- Right-to-cancel notice: Customers in Illinois get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Fence Installer line items + standard terms
Every fence installer invoice in Illinois should itemize work clearly. Standard fence installers use Net 14 terms with a 33% deposit required upfront.
- Materials — billed by itemized.
- Labor — per linear foot — billed by linear-foot (~$18 default).
- Gate install — billed by flat (~$250 default).
- Permit fee — billed by passthrough.
3. Fence Installer licensing in Illinois
Contractor license required in most states for jobs over a threshold. HOA approval often required.
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. Illinois customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
