How does invoice number extraction work?

Below is an example of the three steps our OCR software follows to automatically extract invoice numbers from documents and images.

Uploading invoices to the API

The first step is to provide an image or PDF file of a document containing an invoice number to our API. Usually this is done from a mobile app, email, FTP, or web application.

The document can be sent both cropped (without background) and uncropped (with background). If the image is sent uncropped, our API automatically crops it to the right size. There is also a possibility to use the Klippa scanning SDK in mobile apps.

Image to text using OCR

As soon as a picture or PDF has been received, it’s converted to a TXT file. In this step all the data from the document is extracted, but it is not yet structured.

Getting JSON output from the API

The Klippa Parser takes the data gained from the OCR in step 2 and converts it into structured JSON using machine learning. 

The JSON is then returned as output from the API. The invoice number is now recognized and extracted. From here, the field can easily be processed into your database.

Whether you are processing invoice numbers for financial or other purposes, Klippa is here to help.

The image on the left is a simplified example of the JSON response. More fields can be extracted if required.
