Look inside

Acme Widgets, a manufacturing company, uses an AI-powered Google Workspace add-on to automatically extract information from supplier invoices. Your task is to extend the add-on’s functionality so it can handle expense claim receipts, as well. You’ll add a Document AI processor designed for processing expenses, and you’ll enable additional fields in order to group related receipts. To increase user convenience, you’ll enable the uploading of local files and add a tab to re-pick recently selected files. Lastly, you’ll create unit tests that will help you update the add-on with more complex changes in the future.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
