The Deposit tab of a Contract will always be visible in edit mode and from manager views, but this can be hidden from end users (ex. Parents) by removing the Payment Gateway and payment information from the Payment Block on the Contract.

As a manager:
  1. Navigate to Enrollment Management.
  2. Select Enrollment > Contracts > Manage Contract Forms.
  3. Click Edit to the right of your Contract.
  4. Click your Deposit/Payment tab.
  5. Click Block Settings.
  6. Make sure the Payment Gateway drop down shows " -- Select an Option --" (no payment gateway selected).
  7.  Remove any deposit amounts.
  8. Click Save.
This will then remove the Deposit tab/payment block from the view of your end users (ex. Parents).
