Garnishment Service Interpretation System

Client              : ADP, San Di mas, CA                                                                                                Mar’06- Feb’08

 

The ADP Garnishment Service Organization (GS) offers a Comprehensive Service product.  One of the main components of this service offering is the interpretation of client garnishment orders.  The Garnishment Service Production organization utilizes a custom ADP application designed specifically to interpret orders.  This system is called the Garnishment Service Interpretation System (GSIS). 

 

In the current process all orders received by the client are sent to ADP via fax or hard copy.  All of these orders are fully interpreted and entered into GSIS.  A file is then created containing the data from the interpreted orders.  This file is transmitted to the client and uploads into the client’s payroll system. During the upload process, a number of orders are determined to be either for persons that are not employees of the client or are prior employees that are no longer actively employed.  These orders cannot be uploaded into the client’s payroll system; rather a file is generated and returned to ADP that allows the ADP GS system to generate notifications to the garnishing jurisdictions notifying them of the invalid status of these orders.
