Substitute preservation
It consists of the digitization and dematerialization of administrative and accounting documents . The replacement storage of administrative and tax documents, previously difficult to achieve due to the obstacle represented by the large amount of paper documents, finds a new impetus in electronic invoicing.
For this to have legal validity, it must be done with specific methods and technologies that are not available to everyone. It is highly advisable to appoint a professional firm as the "responsible party for substitute storage".
