PART 3   - HOW TO SUBMIT YOUR OFFER USING e-SUBMISSION  Registration in the Participant Register  Please note that a request for supporting documents by the  EU Validation Services in no way implies that the tenderer has been successful. How to Submit your Tender in e-Submission  10  Previously called European Commission authentication system (ECAS)  31  You must submit your tender electronically via the e-Submission application available from  the e-Tendering website before the time limit for receipt of tenders.  The e-Submission application allows economic operators to respond to call for tenders by  preparing their tenders electronically in a structured and secured way and submitting their  tenders electronically. The e-Tendering is the starting point for launching the e-Submission  application.  Make sure you submit your tender on time: you are advised to start completing  your tender early. To avoid any complications with regard to late receipt/non-  receipt of tenders within the deadline, please ensure that you submit your tender  several hours before the deadline .  A tender received after the deadline indicated  in the procurement documents will be rejected. Any economic operator willing to submit a tender must be registered in the Participant  Register - an online register of organisations and natural persons participating in European  Commission's calls for tenders or proposals. On registering each participant obtains a Participant Identification Code (PIC, 9 - digit  number) which acts as its unique identifier in the Participant Register. A participant needs  to register only once  –  the information provided can be further updated or re-used by the  participant in other European Commission's calls for tenders or calls for proposals. At any moment during the procurement procedure the Research Executive Agency Validation  Services (hereafter  the EU Validation Services) may contact the participant and ask for  supporting documents on legal existence and status [and financial capacity]. The requests will be made through the register's messaging system to the e-mail address of  the participant's contact person indicated in the register. It is the responsibility of the  participant to provide a valid e-mail address and to check it regularly.  The documents that may be requested by  the EU Validation Services  are listed in the EU  Grants and Tenders Rules on Legal Entity Validation, LEAR appointment and Financial  Capacity assessment.
