Upcharge or Additional Fee

ShipStation's checkout rates feature does have the ability to do this, but only for specific store integrations (currently, Shopify, BigCommerce, Magento, and Wix). 

We will be expanding the feature to more integrations in the future though. If you would like to see this for a specific ERP or middleware, please let us know which ones in the comments.

i'd like to see this feature for the ERP "acctivate"

I would like to see this feature available for Channel Advisor

@SuperMgr-Sarah Hi Sarah,

I noticed this response was a while ago, and was wondering if a handling fee has been dropped by Shipstation. We are currently very interested in adding the handling fee for our FAIRE orders. Can you tell me what the status is on this?

Kind regards,

albert

SuperMGR-Sarah: We export orders from odoo to shipstation manual orders.  After printing labels, shipstation writes back tracking number, service and cost.  We would love to have cost already inflated by the example X% upcharge or a $X fee per shipment.  And we would love the shipstation rate quote screen to display this inflated charge only, for purposes of customer shipping quotes.
