How to Read an Invoice with AI

James Gallagher's guide, published on the Roboflow Blog, outlines a method for using AI models, such as GPT or Gemini, to read and process invoice data, which can then be integrated into business logic applications. The guide walks readers through creating a workflow using Roboflow Workflows, a web-based application builder, where users can chain tasks like object detection and vision question answering to read invoices. It emphasizes the use of a multimodal model, specifically a GPT model from OpenAI, configured to extract structured data, including sender name and total cost, from invoices. The workflow is further enhanced by integrating custom logic that processes the data to send notifications via Slack. The guide concludes by demonstrating how to test and deploy this AI-driven invoice reading system, offering potential applications such as pre-filling accounting platform entries with extracted invoice data.
