# 167 I built an AI agent finance department (full build)

Building an AI-powered finance department requires leveraging workflow automation tools like N8n to create a central CFO agent that delegates tasks to specialized sub-agents. By utilizing large language models and structured system prompts, these agents handle distinct financial functions—specifically financial planning and analysis, accounting, and treasury—without requiring extensive coding knowledge. This modular approach enables cost-effective scaling by assigning complex reasoning tasks to advanced models while delegating routine queries to lighter, specialized agents. Implementing this system automates repetitive processes, freeing human staff to focus on strategic growth and relationship management. Corporate finance expert Mike Dion demonstrates that non-technical teams can replicate this enterprise-level automation for minimal monthly costs, transforming how small to mid-sized companies manage their financial operations through scalable, AI-driven delegation logic.
