Yes! ShipHero Fulfillment App allows you to upload attachments to an order.
This will be useful if you upload B2B, FBA labels or instructions for order customizations, etc.
Please note that the attachments must be uploaded fully for our support team to be able to visualize them and download them.
The supported formats are pdf, png, jpg, and CSV.
Important: If the warehouse is processing the order and you upload the file after, there are no guarantees that we can process the order with those files.
Please make sure to add the order on hold if you are still adding attachments. More info HERE
