You can use Aria to create accounts that have a few basic options. To create accounts with advanced options, such as alternate rate schedules, use the create_acct_complete API call.
Can an Account be Deleted?
Once an account is created, you cannot delete it. Aria is a transaction-based system. You can change account statuses to a non-active, non-billable status, but an account record cannot be deleted. You can also set accounts to "Archived" or marked as "Test" status, but, due to referential integrity constraints, there is no way to remove accounts.
