Using the Out-of-the-box invoice model, it seems there is a unique Norwegian field missing:
KID-number (kundeidentifikasjonsnummer / customer identification number).
It’s called other names for other countries.
I also miss a general field for “Your reference”. This should be in the standard model.
Also, labeling incoives is mundane, it should be possible to upload PDF’s together with an XML with all the correct fields.
Then in the label monitor you could Predict the values, and match the output against the XML.
We already have all the correct data (extracted manually) in our system which could be used as training data. Would speed up the process of training a model on our own data very much.
