My team spends hours extracting data from PDFs and invoices. I’m looking for an AI workflow that can ingest these documents, extract specific fields, and push them to a CRM. Which models or platforms are currently the most reliable for this kind of high-accuracy automation?

For high-accuracy document analysis, the "gold standard" right now is combining a strong OCR (Optical Character Recognition) like AWS Textract or Azure Document Intelligence with a Large Language Model like GPT-4o. The OCR handles the layout and text detection, while the LLM understands the context of the fields. If you are looking for a more "out of the box" solution, platforms like Rossum or Docsumo are specifically built for invoice automation. They have built-in validation steps which are crucial because LLMs can still hallucinate numbers if the document scan is blurry.
How are you handling the privacy aspect of these documents? If you’re processing sensitive financial invoices, are you comfortable sending that data to a third-party API like OpenAI, or are you looking at local models?
AWS Textract combined with a simple Lambda function is very cost-effective for this. It’s less "flashy" than a full LLM but much more reliable for structured data.
Patrick is right. Sometimes a simple tool is better. I’ve found that using LLMs for simple table extraction is often overkill and more expensive than traditional OCR.
Scott raises a vital point. For sensitive data, we actually transitioned to using Llama 3 hosted on our own private cloud. It took more effort to set up the infrastructure, but it eliminated the data privacy concerns we had with public APIs, and the accuracy for extraction tasks is surprisingly comparable now.
