First of all, you will never have 100% success if your invoices aren’t built exactly the same, and even then it’s highly unlikely.
Also, 17 invoices for training a model is not a lot, some might even say it’s definitely not enough. It depends on your invoices and how similar they are.
For successfully running Training or Full pipelines we strongly recommend at least 25 documents and at least 10 samples from each labelled field in your dataset. Otherwise the pipeline will show an error “Dataset Creation Failed”
I recommend using the Document Understanding Template for your automations. That way you have a process where you can continually retrain your model based on documents that weren’t extracted correctly.
