At the beginning of a project we assemble a team of professional developers, QA specialists, designers and project managers – and expand the team in case of necessity. 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. We are absolutely flexible with the project payments & milestones. Hourly-Paid Basis - billing is done according to amount of time spent by the team. Usually is used on on-going projects and projects with incremental development approach. Intellectual property (IP) rights along with the source codes are passed to the client after the final payment from the client.
