Pre-audit guidelines


Pre-audit is a three-step process – three different people need to review each document that is required to be pre-audited (See Statute 81-1111).  This three-step process usually consists of a person collecting the necessary support and entering the document into NIS, a second person who reviews and approves the document on-line and a third person (usually called the pre-auditor) who ensures the document meets Statutory requirements, State Accounting Policies, Agency policies, and who then posts the document on NIS.


Statute requires that documents equal to or greater than $1,500 be pre-audited in addition to those documents with “sensitive” coding.  Click on this link for a list of transactions which need to be pre-audited.  Click on this link for a listing of “sensitive” object codes.


Always conduct an on-line review of your documents.  The A/P Voucher pre-audit report is a valuable tool to use in your review, but unless you are also reviewing the on-line document, there is a risk that changes could have been made after running this report and before posting the document.


We recommend that the person posting the document also be the pre-audit person, i.e., the last person to verify the on-line document and original supporting documentation is correct.  If the person posting the document is not the pre-audit person, the poster should verify the payee and the total dollar amount from the invoice agrees to what is shown on NIS.  Each agency should have procedures identifying what each person in the pre-audit process is reviewing.


We recommend using the Pre-audit report as part of your review as this report contains information that you may not see if you are reviewing  documents on-line under Review/Approve/Post Batches.  For example, the pre-audit report will tell how the payment is to be made – warrant or electronic transfer, information which is not available if you are reviewing the document under Review/Approve/Post Batches.  In addition, pre-audit staff can use this report to see if there are any exceptions, error and warnings messages which may need to be corrected.  Suggestions for reviewing the Pre-audit report are documented below.


We recommend that warrants be returned to an agency only when absolutely necessary.  If a warrant is returned to an agency, it should be returned to someone other than the person who posted the document for handling.


A checklist at the bottom of this page has been developed to assist agencies in conducting a pre-audit review.  If your agency has specific items which need to be reviewed, please add them to this checklist.  Please continue to monitor this web page, as we will be making updates which will further assist you.




Segregation of Duties


Segregation of duties is an internal control intended to prevent or decrease the occurrence of innocent errors or intentional fraud. This is done by ensuring that no single individual has control over all phases of a transaction.

There are four general categories of duties: authorization, custody, record keeping and reconciliation. In an ideal system, different employees perform each of these four major functions. In other words, no one person has control of two or more of these responsibilities. The more negotiable the asset, the greater the need for proper segregation of duties - especially when dealing with cash, negotiable checks and inventories.

Some examples of incompatible duties are:
· Authorizing a transaction, receiving and maintaining custody of the asset that resulted from the transaction.
· Receiving checks (payment on account) and approving write-offs.
· Depositing cash and reconciling bank statements.
· Approving time cards and having custody of pay checks.

Also, in a small operation, it is not always possible to have enough staff to properly segregate duties. In those cases, management may need to take a more active role to achieve separation of duties, by checking the work done by others. Sometimes, the knowledge that records will be checked by others is enough to prevent misappropriation of assets.






Review A/P Voucher pre-audit report:


If this is an item that was purchased with a purchase order, the purchase order number will be printed in the P.O. Number field.  If this field is blank, STOP now and return document to the appropriate person so that a three-way match can be processed.


Review Payment Handling Code on pre-audit report to make sure any warrants returned to the agency are necessary


Review report for error messages; determine if actions needs to be taken (when paying IBT’s, you will receive an error message to verify payee is correct.  On IBT’s only, this message can be ignored.)


Review Payee Number area to ensure payment is being made to the correct entity and their correct payment address which should be shown on the invoice




Review on-line Batch:


NOTE:  When reviewing documents on-line, be sure to click Cancel /Close when you have completed your review.  Do NOT click OK.  If you do click okay, it will change anything set up through special handling and it will reset the document back to pending.
