Local AI Agents for FP&A: Building Autonomous Financial Analysts with Ollama, LangChain, and Python

By Vincent Bisette

Reactive Publishing

Local AI Agents for FP&A shows finance professionals how to build private, autonomous AI systems that analyze financial data, generate insights, and support decision-making-without sending sensitive information to the cloud.

Using Ollama for local large language models, LangChain for agent orchestration, and Python for implementation, this book walks you through creating practical AI agents tailored to Financial Planning & Analysis work. You will learn how to design agents that can query data, perform calculations, summarize results, and produce structured outputs while keeping everything on your own infrastructure.

Inside you will find:

Clear explanations of how local AI agents differ from cloud-based tools and why that matters for finance teamsStep-by-step guidance on setting up Ollama, connecting it to LangChain, and writing Python code that controls agent behaviorPractical patterns for building agents that handle common FP&A tasks such as variance analysis, forecasting support, and report generationGuidance on data handling, prompt design, tool use, and error management so agents remain reliable and auditableWorking examples that demonstrate how to move from simple scripts to more autonomous multi-step agents

The focus is on usable systems you can run and control yourself. No prior expertise in large language models is assumed, though basic Python knowledge will help you move faster.

Whether you work in corporate FP&A, consulting, or data-driven finance roles, this book gives you a concrete path to deploying AI agents that respect privacy, reduce dependency on external services, and fit into real financial workflows.
