I had a side project I worked on for 6 months several years ago to do something similar albeit slightly less shady. When I was working on it there was a business on their that was using it to do human transcription of retail store receipts. I think it was a marketing company to figure out what customers were purchasing. My plan was to develop a computer vision algorithm that would do 90% of the work and then just farm out the verification step to humans to increase their productivity. I got as far as downloading the receipts and attempting basic image processing to try and touch up/reformat the receipts. Training a model to extract data would have been a better approach but I didn't have the skillset or inclination to continue.
