You are signing up for a 30-day trial of Lightning Enterprise Edition. You’ll have 30 days from the time you start the trial to complete your Power of Us application. You can also request a trial extension by sending us a message. If you choose to apply for Salesforce.org’s Power of Us program, your selected trial will become your permanent Salesforce configuration.
This trial version of Lightning Enterprise Edition does not include the Nonprofit Starter Pack (NPSP). If you want NPSP included with your trial edition (recommended), go to the NPSP trial sign up page. If you are a Higher Education institution, start a trial for Higher Ed.
