A centralized, online clinical study system configured to coordinate aspects of a clinical study can include a training module configured to evaluate whether users have completed training for selected workflows for the clinical study that are available from the clinical study system, and to provide training to registered users for the selected workflows. The system also can include a financial engine configured to determine when a participating site meets or exceeds a milestone of the clinical study and to initiate a payment to the participating site. Further, the system can include a module configured to receive and verify clinical research data and to designate the verified clinical research data as official source data for the clinical study.
