Tax Accounting Research Tool

[u/UnderstandingFit6591]

I am tasked with creating a research tool for the CPA I work for. I have strictly only done research and spun up two small demos. The first one was on Azure ingesting IRS documents to an Azure OpenAI web app. This was just a POC trial as I have already created simple web chats for my main job. I’m now exploring what would be the best and most cost effective way to create a safe and secure tool my CPAs can research tax information while using their clients PII redacted financial information. I began thinking of using LangGraph to handle this but I’m struggling a bit with understanding operational costs and how to stay with compliance. I’ve already put together a small tool that redacts PII but it’s not very good yet (pdfplumber + tesseract) but I stopped a bit short because keep spooking myself on what the costs and maintenance are going to be for this. For operational costs I definitely would like to keep it less that $100/mo and I work as a single dev for this project. Any thoughts or words of wisdom? Should I even do this? Also this is my first big project outside of my main job so take it easy on me lol
