I built a 3-part automation system to handle the client’s full sales lifecycle. Workflow 1 captures and normalizes leads from website forms, Facebook Ads, and email, removes duplicates, and stores them in a CRM. Workflow 2 uses AI to generate personalized WhatsApp follow-ups with email fallback and updates lead status automatically. Workflow 3 listens for payment events, marks deals as won, logs revenue, and notifies the team in Slack. The system eliminated manual lead handling and ensured instant follow-up and accurate sales tracking.
