The European Commission launched the “Once-Only” Principle Project (TOOP) on 1st January 2017. This project is part of the EU eGovernment Action Plan 2016-2020 and will contribute towards increasing the efficiency of the Digital Single Market. The project will ensure that information is supplied to public administrations only once regardless of the company's country of origin therefore eliminating unnecessary burdens for European businesses who are asked to repeatedly present the same data and documents.
