Hi David,
This is a great suggestion, I can fully appreciate how this would be helpful to a number of customers. We will take a look with our development team and see if this is feasible.
Judging by the number of votes received over the last couple of years this is a very popular request.

We Released Purchase Orders last year and it supports a delivery address
I would prefer to have customers with different delivery addresses, we work with many customers with several branches & have to set them up as separate customers which makes invoicing complex, if there was an option for more branches that would definitely ease workload.
