Why leave the freelancer a review at the end ?
The freelancers' reputations are important, and Malt gives them a chance to put their expertise forward and build an e-reputation.
Thanks to the clients who trusted them, they can develop their activity and capitalize on their reputation. After the mission is completed, you have 1 month to leave and modify a review.
If the mission went extremely well, you can also leave a bonus for the freelancer by asking them to modify their ongoing quote before confirming the project's end :)
