FreelanceEngine is a unique freelance jobs posting and bidding online marketplace. There are multiple ways to monetize. Site owners can charge fees for posting jobs, featuring jobs with ads included, and take commission fees of each project via Escrow system.

With the unique Escrow system plugin, freelancers can bid for tasks while employers can invite specific freelancers to bid, and everyone can be secure in the knowledge that all the money is safe with this system. If a project goes south between the freelancer and employer, the administrator can be the middle man to resolve the dispute and either refund the employer or pay the freelancer.

Other features include
Freelancers can choose bid free or buy credits to bid on a premium job post.
Review system on both employers and freelancers
