You can release a payment to the pro from the project management page:
- From your dashboard, locate the project and click on "Manage" option in the right-hand side of the job.
- If you're satisfied that the pro has fulfilled the work in the milestone, click "Release Payment". This will release the amount out of escrow into the pro's account.
- If you're not satisfied that the pro has fulfilled the work at hand, click on the "Request Refund" button or message the pro noting the additional work that needs to be performed.
