Post void
open-in-new
<p>In the context of point-of-sale and accounting systems, the term post void is a <a href="/facts/Database_transaction/q1Etrsl8">transaction</a> which cancels, or deletes entirely, a previously completed transaction. </p><p>The distinction is that the transaction being voided is one that was already completed, versus one that is still in the process of being made. </p><p>The ability to post void a transaction is normally restricted to supervisory personnel. Although the capacity to perform such a transaction is not necessarily fraudulent, there are many scenarios of employee theft, embezzlement, and so-on which could be enabled in part by the intentional misuse of this capability. <a href="/facts/Auditor/123KLyL3">Auditors</a> and <a href="/facts/Loss_prevention/1gn6BaNW">loss prevention</a> departments therefore routinely scrutinize these transactions very closely for this reason. </p>
