At CSSI®, our goal is to simplify the process for you so that your involvement in our study process is minimal. We will either coordinate with you and your client or work directly with your client to secure all necessary documentation to complete the study. We also provide you with cost documents, the 3115, and 481(a) adjustments. By partnering with CSSI®, you will be working with a firm that operates within all approved U.S. tax codes and guidelines.
