Salesforce Nonprofit Cloud is a comprehensive solution built on the Salesforce platform, specifically designed to help nonprofits manage their operations and achieve their missions. It integrates tools for fundraising, donor management, program and case management, and grantmaking into a single platform, eliminating the need for separate add-ons commonly required in older versions. Key features include managing the entire giving lifecycle, maintaining detailed histories of stakeholder and participant interactions, and providing data analytics to track impact and program outcomes.
