How is testing invoiced and paid for?
- The report of analysis has the fee listed as well as test results, but payment is not made from the report. A billing statement will be sent at the end of the month, but payment isn’t made from this either. Finally, Iowa State University Accounts Receivable will mail an invoice and payment is made from that invoice.
- Payment is normally made by check as we don’t accept credit cards.
