How do I seal my bid?

There is nothing that you need to do to seal your bid.  The buyer chooses if the project bidding will be sealed or open. When your bid is submitted, it is automatically sealed or open based on the buyer's choice.

Your bid appears when you're logged in, even though the project bidding is sealed, because you are the owner of the proposal. You will always be able to view your bid information, however, no other service provider can see your bid.
