TourTools® V3 Vendor Module: Deadlines -- TourTools™ can automatically create "To Do" reminders for you based on your input on this screen. In this example, we indicated that a deposit is always due Hotel Washington 90 days prior to the arrival of a group. As soon as our June 2/3 Price/Inventory record is attached to a Package, a "To Do" reminder for 90 days prior will be created.
