New order or another order?

1....
When processing orders I need to know if an order is this customers 1st, 2nd or more order, as we send a lot of brochures & info with the 1st order and less with subsequent orders.

I would like in the orders -> edit page to show "new" or "1/1" for the first order from a customer with later orders showing say "5/10" for their 5th order out of 10 total orders.
This would not be stored in the database but would be generated dynamically each time you enter the edit orders page.

2....
On those occasions where a customer buys an item but it is delivered to another person. I would like to be able to enter an optional telephone number for the delivery address. This is used on the parcel for delivery purposes

The notion of being able to flag a "first-time order" sounds like a great idea & your brochures example exemplifies how that info would be useful.

I'm lost on the 5/10 part, though.
Where would you have this info "shown"?
Is it in case a customer wanted to lookup & print out all their old invoices???

I can't picture using 5/10 in the administrative workflow.
You lookup all records for a given customer... say ten are shown on the results page. They are already shown in order, by invoice# or by order date... so you click on any one of the invoice links to review it.

At that point, what's the merit in having "5 of 10" displayed on the detail page?
What am I missing?

No if you are going thru by customer than your scenario works fine. But I go thru orders sequentually and its here that I would like this information. I can get it by going to customer -> search for customer -> orders. But this breaks the flow when I am going thru orders sequentially.
When going thru new orders I find it useful to know how many previous orders have been placed by this customer. It would obviously show "10/10" for new orders.
