Microsoft SharePoint is a suite that improves organizational efficiency and collaboration through comprehensive content management, company-wide search capabilities, streamlined business processes, and cross-departmental sharing of data and documents. The ecspand product enhances SharePoint by connecting it to other systems like Dynamics and SAP, preventing customers from migrating to SharePoint alone, and offering additional services to existing SharePoint customers. Ecspand also provides mobile apps and a cloud-based option to make SharePoint more accessible across different devices and platforms.
