  • Late-fee cap: Missouri statute Mo. Rev. Stat. §408.020 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 Missouri get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
