Many of the professionals faced situations when the whole project was under the threat of frustration due to the fact that at the last moment one of the involved persons failed the agreement. The reserve system, if it was applied, was unilaterally - to "book" a model, photographer or stylist on the desired date, the shooting organiser gave some funds as an advance payment. But such a scheme does not protect the interests of the organizers, because they still don't receive any guarantees!
Therefore, we created a system of equivalent double-sided reservation. When creating a project on Proved Pro, the project author determines the amount of the reserve for each participant, and only then sends invitations to them. If invited person is satisfied with all conditions, he confirms his participation, and at that moment the agreed amount of the reserve is written off from the balance sheets of both the author and the specialist, which will be returned after the successful completion of the project. In the case where one of the parties failed his participation, the reserve of initiator of the failure is transferred to the injured party.
