You will only need one account to make your Submission and/or your Intent to Bid. You can submit to a Project more than once, but only one account is necessary unless the Buyer specifies otherwise. The account that submits the Intent to Bid must be the account used to make the actual submission.

For more information, please see Creating and Uploading a Submission and How do I submit my intent to Bid?

For projects that allow for multiple submissions, please see our How do I prepare a second submission? page.
