You can withdraw your proposal until you are offered a contract. After that, you’ll need to turn down the offer or end the contract. You are never obligated to accept a project you don’t want. You won’t be penalized by Upwork for withdrawing a proposal or declining an offer.
To withdraw a proposal
- Go to Find Work > Proposals
- In the Active tab, find the proposal you want and click the Withdraw link.
- Select a reason.
