I'm currently building a POC for my company, trying to process the vendor invoices with the AI Builder Form processing capability.
I think MS is of to a great start with this, but we're not there yet 🙂
One of the biggest drawbacks we've experienced during the POC is the fact that you have to train the model separately. This means that there's a lot of (training) work to be done before the model can be used in an app or flow.
It would be a far more intuitive experience by people in the finance department if they could see the extracted fields on the invoice document and train it as they go along.
The current set up means Finance workers have to go back to the model and train for every new vendor or type of layout. Or if a certain existing layout needs more training.
Other AI vendors (i.e. Medius) let us train while processing and approving the invoices.
