Billing can be performed in two ways: Fixed- Price Contract- Project payment to be paid in installments via Upwork escrow system for mutually agreed milestones, which follows a review of the project by the client. We try to keep project delivery time to minimum, but project business concept, work scope and its complexity will determine the final turnaround time.
