Project owner is able to cancel without consent from freelancers
On websites like Elance.com (which hirebee is advertised as mirroring) all parties must consent to cancelling a project after it has been funded and work has begun. On hirebee it allows the employer to cancel the project with an immediate refund, potentially even if deliverables have been delivered already. The proper way to do this (as it is done on Elance.com) is to send the freelancer(s) a notice of cancellation request, and they can accept or deny it. If they deny it, a dispute is automatically formed. This makes the system safe for freelancers, so clients cannot just get a refund after all work has been delivered. There must be an option for the freelancer to open a dispute process before the refund is sent.
