I am going to post a separate post on this but as it looks like you all have experience with the National Accounts, I thought I would post here as well. From what I can see of national accounts the only thing stored on the child is a summary record of sales. The open invoice is recorded to the parent/national account. Other than the summary total by customer and the extra effort of setting up a customer, WHY in the world is this much better than just using Ship To and one customer.
