CLAUDE CODE FOR FINANCE

Your close process depends on people who might not be at their desk next quarter. This book helps you fix that.

Every finance team has the same hidden risk. A few people know exactly how the reconciliation works, or which spreadsheet cell drives the regulatory filing. When they're out sick, everything gets stressful. When they leave the company, it gets dangerous.

Claude Code for Finance teaches you how to build AI tools that make your reporting, compliance checks, and fraud monitoring easier to repeat, easier to check, and no longer dependent on one person's memory. And it does this safely: the AI drafts and flags things for you to review. It never makes the final call. A person always signs off before anything goes out the door.

This isn't a book about asking a chatbot to summarize a spreadsheet. It's a practical, step-by-step guide. You'll build real tools you can actually run, using Claude Code (an AI coding assistant) connected safely to your financial data.

Here's what you'll learn to build:

• A tool that drafts your monthly variance report, and backs up every number with the actual transaction behind it
• A safe, read-only connection between the AI and your financial database, with a full record of everything it looked at
• A compliance report drafter that fills in a template from your real data and never makes up a rule or citation
• A fraud-detection tool that flags suspicious patterns for a human to investigate, and never accuses anyone on its own
• A review system where a second AI double-checks the first one's work, the same way a second person would
• A full audit trail and testing setup built to hold up if an auditor ever asks "how was this number produced, and who approved it?"

Every example in this book uses made-up companies and data, so you can practice safely before trying anything with real numbers. And every piece of code is complete and ready to run. You won't have to guess at the missing pieces.

This book is written for financial analysts, controllers, accountants, compliance officers, and risk managers, no coding or AI background required. It's also useful for the engineers who support these teams and want to understand the finance side better. You'll go from knowing nothing about this technology to having a working, safe tool by the end of the first chapter.

If you're tired of hoping your close process survives the next vacation or the next resignation, this book shows you how to build one that doesn't have to.
