The statement that does not explain the difference between safety stock inventory and the cross-docking method is:
"The cross-docking method can cause shipping delays due to extra storage needs while safety stock inventory can help customers get their products faster."
This statement contains inaccuracies about cross-docking. In fact, one of the main advantages of cross-docking is that it minimizes storage time, as goods are transferred directly from inbound to outbound transport without being stored. Thus, it does not typically cause shipping delays due to extra storage needs, which is more characteristic of traditional warehousing methods.
