In case of problems with the submission of the electronic tender, we recommend that you  call the helpdesk in reasonable time before the time limit for receipt. The time it takes to  submit the tender and upload all your documents may vary considerably depending on the  number of concurrent submissions by other economic operators, the size of your tender  and the type of internet service you are using.

You are  kindly  requested  to  also  e-mail  the  notification  letter  to  EFSAProcurement@efsa.europa.eu.
