Upgrade your legacy ProContractor login to Trimble ID

Instructions for setting up a Trimble ID you can use to log in to ProContractor.

  • You must have access to your email to complete the upgrade because the upgrade process sends an email with a validation code which you must retrieve and use.
  • You only need to take these upgrade steps once for your account.
  • For additional information, see Legacy login to Trimble ID FAQ.

  1. In the login screen, enter your ProContractor username and password and then select Login with Trimble ID.
    ProContractor validates your credentials and then the Trimble Sign In page appears.
  2. Choose one:
