# Create and Manage Trialforce Source Orgs

A Trialforce Source Organization (TSO) is used to create Trialforce templates, which are the basis of customer trial orgs. You can create a TSO with Environment Hub or a Trialforce Management Org (TMO). In most cases, either method is fine, with two exceptions. If you plan to brand your emails or login page, use a TMO. To create a Professional Edition TSO, use the Environment Hub. If your TSO is about to expire, request an extension.
