Mission Brief

Most UK service businesses and estate agencies lose over 60% of potential leads because enquiries arrive after office hours or wait hours for a reply. This system connects directly to the official WhatsApp Business API, instantly responding to incoming enquiries in under 20 seconds. It intelligently qualifies the customer’s budget, urgency, and requirements using structured schema validation, books confirmed appointments into staff calendars, and commits clean customer records straight into the CRM.
