It might be useful for you to leave a message to your supplier when you place the order to AliExpress, to ask him not to include a receipt, to let him know you are dropshipping or to tell me him not to add gifts to the order.
It is very easy to do.
Go to DSers - Setting on the bottom left of DSers
Open the Other menu, and find the Leave a message to AliExpress sellers
You can write a default message to your supplier (in English or Chinese) there. The message will be sent to your suppliers with each order you send to AliExpress from DSers.
You can also leave a message in a specific order. On the right side of the order, click on Action - Message
A new window will appear with your default message written, but you can add more information, if you are ordering a product which require a name for example
If you want to add a picture, you will need to first put the picture on an online site (like Imgur), and paste the link there. We are working on improving this feature
