Interagency Billing Transaction (IBT)

When acquiring or providing goods and services to or from Nebraska state agencies, other than the University of Nebraska, the billing procedure is an internal transfer of state funds between agencies and is accomplished using the Interagency Billing Transaction. Do NOT use the IBT for transactions involving UNMC, UNO or UNK. The IBT form and instructions can be downloaded from SAPPHIRE.

IBT Billing Process
The billing department (agency providing the goods or service) is responsible for initiating the IBT. The billing department should:

  • Download the IBT Invoice-UNL from SAPPHIRE.
  • Complete the IBT, leaving the invoice number blank (Accounting will enter the SAP Doc #)
  • Keep a copy for your records.
  • Forward IBT to Accounting with any necessary backup material.

The Accounting Office will:

  • Enter the invoice into SAP as a “TN” document type, with a document number ranging from 90000000 – 90999999.
  • Send the original invoice to the expending state department for payment.

IBT Expending Process
When ordering goods or services from a state agency other than the University, it is necessary to provide your department's NIS address book number with your order so that the agency can initiate an IBT. See IBT Agency Code List for your number.

If you are the expending agency and have received the IBT from another state agency, you should first check to see if the billing belongs to your department, and that the amount is correct and due. If the billing is correct you will need to:

Indicate your University cost object and all accounts to be charged in the blank area of the form.

  • Sign the form to indication approval of payment.
  • Keep a copy for your records.
  • Forward the original to the Accounting Office.

The Accounting Office will:

  • Enter the invoice into SAP as a “KN” document type.
  • The IBT will interface with the NIS system to generate the payment.

IBTs will post to your monthly financial reports at the time Accounting processes them. This does not mean they have been processed at DAS (Department of Administration Services).

For any questions regarding the IBT process, please contact Barbara Opp at 472-2881 or Diane Ciecior at 472-2705.
