Since January 2018, the French Tax Administration has required that all companies using accounting management software comply with the French standard, NF203. NF203 certification covers the security of all functional areas of computerized accounting, including purchasing, sales, inventory, and fixed assets, as well as digital safes (NF203 CCFN). Companies are certified by INFOCERT, which is authorized by the certifying body, Association Française de Normalisation (AFNOR).
NF203 is based on the standard NF Z42-020 for digital safes—IT solutions that back up, allow access to, and archive documents and data to highly secure clouds. The digital-safe component of this standard complements an electronic archiving system and confirms the integrity and traceability of the digital objects stored there, including by encrypting the stored data.
To achieve compliance with NF203, software products must also be certified for compliance with the requirements of international standards, including ISO 9001, for a quality management system, and ISO/ IEC 25051, for the product’s functionality. ISO 9001 sets the criteria for a quality management system that supports good product design; ISO/IEC 25051 establishes requirements for how a product is developed, tested, and validated.
