Formie Beacon CRM is a completely free Craft CMS plugin that adds Beacon CRM as a Formie integration. It reads your account schema at runtime, so you can send submissions to built-in or custom record types without hard-coded fields.
Map form values, use fixed values, upsert existing records, and only send data when a visitor has opted in. The plugin is open source, MIT-licensed, and is not currently distributed through the Craft Plugin Store.
