1. Louisiana-specific invoice requirements

  • Sales tax line: 4.45% state rate. Most services rendered in Louisiana are exempt from sales tax — but materials, parts, and tangible goods are not. State 4.45%; combined often 9-11%, highest in nation.
  • Late-fee cap: Louisiana statute La. Rev. Stat. §9:3500 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: Louisiana requires a signed agreement for any job over $7,500. Reference the contract number on the invoice.
  • Right-to-cancel notice: Customers in Louisiana get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.

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. Louisiana customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
