This simplest way to set this up is to use prepaid (invoicing policy on ordered quantities) subcontracted service products.

If you want a Transfer (because YOU handle the paperwork) for the "delivery" of the Product to the Customer - use a regular product with drop shipping for the second step.

Setup

1. In Purchase --> Configuration --> Settings, activate Dropshipping
2. Create two Services - one for the Unit, and one for the Local Delivery - set the Invoicing Policy to Ordered quantities
3. On the Purchase tab of each Service, add the Vendor, set Subcontract Service to True and Control Policy to On ordered quantities

Workflow

• Create a Sales Order with two lines - one for the Unit and one for the Local Delivery. Leave the prices at $0 until you have information from your Vendors and Delivery Company
• Confirm it to create two Purchase Orders - one for the Unit and another for the Local Delivery
• On the PO for the Unit, change the Dropship Address to the location of the third-party Warehouse
• On the PO for the Local Delivery, add a note line with the address of the third-party Warehouse
• Process each Purchase Order as you normally would, adding the price and confirming the order when things are finalized
• Add the prices of the Unit and Local Delivery (with your markup) to the Sales Order, then Invoice as you normally would
•
