Audit trails: Complete data lineage for compliance

Data transformation: Clean, validate, and enrich data before GHL storage

Cost Optimization

Reduced manual work: 80-90% reduction in repetitive tasks

Tool consolidation: One n8n workflow can replace multiple point solutions

Resource efficiency: Automated scaling based on volume

ROI Metrics

Typical improvements with GHL + n8n:

Lead response time: 95% reduction (minutes → seconds)
