Using Gemini 2.5 Pro to validate information across PDFs

Mint

7 hours ago

In many business processes, especially in finance or legal operations, validating information across multiple PDFs is a recurring nightmare. It often means switching between documents like contracts, compliance checklists, and payment receipts—each stored in different formats, layouts, or systems.
Whether it's checking if figures match, confirming dates, or verifying signatories, these manual cross-checks are tedious, prone to human error, and almost impossible to do at scale.
For example, in large enterprises, shared service organizations often process hundreds of invoices every month, each requiring validation across multiple PDF documents.
Processing invoices isn't just about checking numbers. Each invoice needs to match with a purchase order and a goods receipt note—three separate PDF files per transaction. Doing this manually is slow, error-prone, and frustrating. Manual checks delay payments, create approval bottlenecks, and lead to frequent errors in compliance and vendor reconciliation.
