Do I have to answer the entire questionnaire in one session? EcoVadis Support (BOA) January 03, 2018 21:24 Updated You do not need to answer everything at once: you have the option to save the incomplete questionnaire at any time and finish it at a later date. You can also invite other users to access the portal in order to help you answer and/or provide supporting documents. Please always remember to save the page you are working on prior to closing your questionnaire, using the commands at the bottom of each page.
