When two or more people pay separately for the same child each person must be set up as the Primary Payer on their own separate account.
- Create a New Account for each party, for example one for mom and another for dad.
- Add the same child to each account. On the first account you’ll choose “Add New Child“. For any additional accounts you’ll choose “Add Existing Child” so the system recognizes them as the same person.
- In the Billing Box set up the fees to be charged to each account. Since the Billing Box is tied to the child it doesn’t matter which account is displayed when you access the Billing Box screen.
