The payment of a mission is staggered in milestones, in accordance with what has been agreed in the technical and financial proposal signed by the Client. Thus, milestones can be paid in advance by setting aside funds in an escrow account with our payment partner (MangoPay) until the Client has validated the milestone, and this validation triggers the release of funds. The second way to pay for milestones is by bank transfer within 30 days of receipt of the invoice generated when the Customer validates the milestone in question.
