Automatically finding specific boxes/fields is quite interesting. I maintain a Python package[1] that processes invoices using a template/regex-based approach. It works alright, but eventually runs into some limitations. The box-model from the article could push it further.

Hey this is great, I made something ad-hoc to do this for a client and might borrow some ideas to improve it.

I heavily leaned on AWS Textract for the bounding boxes though, as the kind of data I had to extract didn't have very well defined fields. I used some of the techniques described in this link [0] particularly around table extraction.

I really like how you define the fields in YAML though, I defined mine in code and it ended up being a bit messy.
