Functional Excise System Specification (FESS) Version 3.41


The Functional Excise System Specification (FESS) is the essential deliverable of the EMCS System Specifications, as it gives the full specification of the functionality of EMCS. It aims at:

  • defining precisely the scope, context and participants of EMCS;
  • detailing the complete functionality required;
  • serving as baseline for further design and development of technical components making up the operational EMCS;
  • some differences may occur between the FESS and the DDNEA, however, the DDNEA should be taken as the guideline for development.

Please be aware that the documents may change in the course of this development. Revenue will make every effort to ensure that the correct documents are available on this website. However, Revenue will not take responsibility for any difficulties caused by changes made to documents in the course of this development.
