FINN – Parsing complex invoices with Vision API and GPT4

FINN has 20.000 cars on the road that all want to be serviced and inspected. This happens in hundreds of different workshops all across the country. Every month, we receive more than 1,000 invoices that tell us what car was serviced, at which mileage, at which date, and with which costs. All invoices must be read out for this data. Because we have hundreds of different invoice layouts, conventional invoice parsing software failed. With the GPT Vision API preview and GPT 4, however, we were able to extract this unstructured data with ~85% accuracy automatically, saving us 15-20 working hours a month.
