VIDEO INFO
Part 3 is where everything comes together. We build the complete business expense model and show the full automation workflow from CSV import to AI classification. This is real business automation you'd actually deploy.

What we're building: The full business expense system with CSV import, data validation, custom formulas (UDFs), comprehensive testing, and AI batch processing that writes directly to the database model.

The big shift: Instead of just dropping AI responses into cells, we're building a proper business system with validation rules, status tracking, color-coded visual feedback, and error handling.

What you'll learn: CSV import automation, enumeration patterns, user-defined functions, error bank testing, validation vs testing concepts, and why "the limit is your imagination" when it comes to business rules.

Who this is for: Anyone ready to see what real business automation looks like. We're building something you could actually use in production.

From manual expense categorization to one-click AI processing with full audit trails. Part 4 coming next with advanced workflows and unit testing.
