You can easily edit your bid on a project. If there are any adjustments you want to apply or any upgrades you want to try, you can edit your bid as long as the project hasn’t been closed, deleted, or awarded to anyone yet.
On the project page, locate your bid from the bid list, and click Edit Bid on its lower right portion.
Alternatively, you can go to the My Projects page, and click the Active Bids tab to find all your recent bids. Make sure you’ve toggled the Freelancer view (found on top of the page). On the Action drop-down menu of the project bid, select Edit Bid.
You’ll be redirected to the bid proposal page. Here, you can edit the following:
your bid amount
deadline or the number of days you commit to complete the project
When you’re satisfied with the changes, click Update Bid.
