If you select a payment gateway in the settings, it will set the tracking URL field when you view the product update page. 
Started to wonder why the payment gateway is connected to the tracking number.
If you meant the shipping method, don't forget about the drop shippers.
Work flow:
- Customer places order
- Store owner sends details of order from the email to the dropshipper
- Dropshipper ships order and send tracking number to store owner
- Store owner enters tracking number and sends shipped notification to customer
In this case the shipping method would be set to none because the drop shipper takes care of that.
I tried setting the shipping option without the account numbers and got this error:
Your transaction could not be completed. Either your credit card information or billing address has problems and cannot be processed
I'm charging a flat rate for shipping now.
