Internal Requisition and Internal-Account Bill (IRB)
General Instructions for the Use of the IRB

  1.  Customer department obtains an estimate from the service unit for goods/services and records it in the "not-to-exceed" space on the IRB.
  2. An IRB must originate in the customer department and be electronically signed by the department head before being sent to the servicing department.
  3. Standing IRB's must be encumbered for the total amount of the IRB.  Encumbering funds for an IRB must be done by the Department Receiving Services.  An encumbrance number beginning with a "E" can be obtained using Banner form FGAENCB
  4. Upon completion of the IRB, the form should be submitted electronically to the servicing point.
  5. After supplying the goods/services, the servicing unit completes the billing information on the IRB, and forwards electronically to the Disbursements Department.
  6. NOTE:  To help insure that the financial records are as up-to-date as possible, service units are required to submit billings within 30 days upon completion of the service or delivery of goods, unless an alternative billing cycle can be justified.  If bills are not submitted in the scheduled period, the charge may be rejected and the servicing unit may have to absorb the cost.
