Webshipper makes it easy to handle multiple parcels and shipments for a single order.
Start by selecting the order you want to split.
If your order contains more than one order line, a Split packages button will appear. Click on it and choose the number of parcels you want for the order.
You are also able to drag and drop each order line and place them in the parcels you want. Simply click and hold the three vertical lines in the left side box (just to the right of Weight).
When you are satisfied click Save changes.
Your order is now ready to be shipped. Click Send Order and the order will be sent.
If you wish to only do a partial dispatch, simply unselect the right-corner checkbox of each Package before clicking Send order. Then the order will only send the selected packages and the order will be partially Dispatched.
