Screen flows allow nonprofits to create wizards and sequential screens to complete business processes like forms, scripts, or surveys in Salesforce without coding. Flows fetch, edit, and create Salesforce data quickly and easily. They offer advanced logic and the ability to call other flows and Apex code while requiring no coding experience, test classes, or changesets for deployment. Completed flows can be distributed through Lightning pages, communities, Visualforce, and custom buttons and links.
