Depending on your testing design, paying for the amount of testing used on a daily basis is an account option. This opportunity applies to clients who use electronic testing options. Once a client has set up their testing account and made an initial purchase of test licenses, they may elect to be billed monthly for any additional licenses that they use. This billing option can remain in place indefinitely, so long as the account remains in good standing. Clients must provide assurance of monthly payment of their balance by credit card. Open purchase orders initiated in United States are also acceptable. Many clients like this option, as it allows them to monitor the cost of testing. Invoicing can provide information to indicate the cost of testing for each department within the organization within the same account. Monthly billing is not available for paper and pencil testing options. The full cost for delivery of scored reports of assessments that are administered in paper and pencil format is included in their initial purchase. Talk with your account representative for more details on testing options.
