Score inbound leads with AI, reply by SMS or WhatsApp, alert sales in Slack

## Score inbound leads with AI, reply by SMS or WhatsApp, book calendar slots and alert sales Who it is for. Sales teams that lose leads in the first hour: agencies, clinics, real estate, B2B services. What it does - Normalises the lead from any source (web form, ad platform, HubSpot or GoHighLevel webhook) with a 24 hour duplicate guard. - AI qualification returns a score, intent, summary and a drafted reply. - Hot leads get an instant SMS or WhatsApp reply, three calendar slots, a 15 minute sales task and a Slack alert. - Cooler leads are logged in the CRM and started on a nurture sequence. - A second trigger takes voice agent call ended webhooks (Retell, VAPI), writes the summary to the CRM and books a visit when asked. Setup 1. Set base in Config or replace the HTTP Request nodes with your CRM, calendar, messaging and Slack nodes. 2. Point the form, ad platform and voice agent webhooks at the two Webhook URLs. 3. Set the AI credential on the qualification step. Activate. All external systems are reached through HTTP Request nodes against base in the Config node, so the whole flow imports and runs against any REST backend; swap any of them for the native n8n node of your system.

How to customise. Every rule lives in one Code or Config node and is named for what it decides; change the thresholds there, not in the branches.
