Integrated Warehouse Management vs. Third Party Warehouse Management The difference between these two systems often comes down to a choice of Real Time Updating vs. Batch Updating. With real time updating your warehouse management system (WMS) is continually updated with new orders as they arrive. In a batch update process the WMS is updated on a periodic basis, often once a day and usually at night. In such a system orders which arrive on Monday can't be picked until Tuesday.
You choice may also affect the resolution of technical problems. Sometimes; not always, when you integrate two systems and encounter problems the vendors may point the finger at the other one. |
