One of the biggest troubles faced by any business is to manage the files and documents that are stored in different formats and at different places. SharePoint provides a centralized portal with credentials in Ms Office format. They can be accessed by everyone, without any compatibility issues.
SharePoint allows documents, spreadsheets, tasks, calendars, and more to be integrated into user-defined sites that allow internal publication and collaboration between team members. Add document management, workflow, digital rights management, and Outlook Integration, and you have an incredibly rich environment for sharing within an organization.
