Use the Alternates tab in the Manage Estimates screen to create alternate options for the estimate.
Alternates are options that may or may not be included in the final estimate. They are possible additions, deletions, or changes to a project. Typically, these are contract changes subject to negotiation with the client, who will make the final decision based on cost, project scope, or any other factor the client deems important. The final estimate becomes the original estimate plus all alternates accepted by the client.
