Why Electronic Invoices?

Every year billions of invoices are exchanged. The majority is emailed in an unstructured PDF format, which means only humans can read and process it.

Invoice-x is a collection of open source applications and libraries aimed at automating the invoicing- and accounting workflow for businesses. Currently we offer tools to extract structured data from legacy PDF invoices, as well as embedding and editing structured XML-representations in hybrid invoices.

Use unstructured data in legacy invoices.

invoice2data is a Python library and command line tool to extract structured data from PDF invoices using regex templates and (optionally) OCR.
