Is it necessary to set up rules in Finmatics?

You don't need to set up any rules as with other programs.

Finmatics uses auto-machine learning (Auto-ML) to extract data from documents and predict information such as G/L account, purchase orders, tax codes or business partner assignment. Thus, you don't need to set up any rules like with other programs to be able to  achieve a high automation rate in Finmatics. Finmatics takes care of the entire task automatically in the background and usually learns with every correction.
