If a service professional fails or refuses to pay for delivered leads or incurs unpaid balances on their Angi Leads account, the platform typically suspends the contractor's profile, halts new lead dispatches, and restricts access to customer connection tools. Continued non-payment can result in the account being sent to third-party commercial debt collection agencies, potential impacts on business credit ratings, and formal termination of the service agreement in accordance with the platform's standard terms of service.
