The Submittal123™ system uses your address and other contact information to create a letterhead look on the cover page and content list, so it is important to keep it up to date. To change any of your basic client information (address, phone, etc) press the "Edit Client" button. A pop-up dialogue will show you what is currently in our system for your group. You can adjust whatever is pertinent, then click "Edit Client" and your information will be updated.
