Customizeable Labels/Barcodes for Order Items
If Shipstation would allow me to add a label to each item in an order and allow me to customize that label I could manage most of my production using just Shipstation.
For example if I sell a wallet and a shirt in an order, the wallet and shirt would each have a label that I could print out and stick to the item during production.
The label could include: Total number of items in the order (Item 1/1, Item 1/3, etc), buyer name, sku number, order number etc etc.
This would allow me to use shipstation as production software as well as shipping software. Sample label attached.
