In some cases, you may want to fill part of the order yourself, not with Topdser.
What you need to do is to manually fulfill part of the order you don't want to process.
Manually Fulfill Part of an Order
First, you need to click "Mark as Shipped" on the order you want to manually fulfill.
A window will appear for you to revise the part of the order you want to manually fulfill.
Change the number of products you don't want to manually fulfill to 0. The number of products you want to manually fulfill remains the same.
Click "Mark as Shipped Single", this part of the order will be fulfilled.
The other part of the order will still be waiting to be placed! You can place it to AliExpress normally as you would with any other order.
The other part of the order will be moved to the Shipped tab and you don't need to care about it anymore!
