Commercial Late Payment Terms & Standard Practices

In standard independent contractor agreements across the United States, commercial invoice terms usually specify Net 30 or Net 60 payment schedules. Standard commercial interest rates range between 1.0% and 1.5% per month (12% to 18% APR) on past-due balances.

To legally enforce late fee interest on client invoices, contract terms should explicitly state the grace period, monthly interest rate, and right to recover collection costs. Ensure your contract includes clear late payment provisions before starting client engagements.
