Billing Questions and Answers

How often are invoices processed?

The facility processes billing on a monthly basis during the first week following the month of service and are emailed to the billing contact of your department or institution.

Why can't invoices be issued outside the billing cycle?

Processing invoices outside the normal billing cycle increases the chance of errors and is time consuming. Our system is automated and when an individual order is pulled out of the system, the likelihood of a duplicate billing and other billing issues increases. We strongly encourage all users to plan ahead so that individualized billing is avoided.

Who receives the invoices for the orders that I submit?

Invoices are emailed to the billing contact of your department or institution. Please make sure your information is current.

My accountant didn't receive a copy of the invoice. Who do I contact?

Will you pre-bill for services not rendered?

What are the methods of payment for an internal user?
