To dematerialize the management of expense reports, it is necessary to follow the following principles:
Legal framework: article A102 B-2 of the tax procedures book which governs the digitalization of professional expenses.
- Identical reproduction of the original: the copy must conform to the original in image and content.
- Nothing should be altered, retouched or modified.
- If the file is compressed to reduce its size, there should be no loss of information.
All documents must be digitized and stored in a PDF format or in a PDF A/3 format (ISO 19005-3) in order to guarantee the interoperability of the systems and the sustainability of the data.
A security, compliance or time stamping system corresponding to at least the one-star general security reference system (RGS) must be put in place, making it possible to record in particular the dates of the various operations carried out.
