If your search does not return any results, please check with your Sheffer CSR as there may be additional information available. Sales Order Search: All sales orders must be searched starting with "SO" followed by the order number. Example: "SO1234567" They must match Sheffer’s sales order number exactly. Purchase Order Search: Purchase Orders are entered as they are received on your PO. Due to various formats across different companies they may be difficult to search. Hint: If you are having trouble searching by your PO number, try to search using just a portion of the PO with no spaces or dashes. Example: If my PO is "PO-1354589 231" , the best way to search would be by using "1354589" ***NOTE:You must search at least 4 characters and we will match what you enter, no matter where it is located in the PO number. This may pull back multiple results, only one of which may be your PO. Please contact your Sheffer CSR with any questions you may have.
