Edit Invoice Prices AFTER Delivery

I feel as though the Sales Order / Delivery note / Sales Invoice process is all forced upon the accounts receivable/Office people.  The office must double check all their pricing BEFORE any shipping details/delivery note is processed.

To me the process should look like this -

Sales Order - Office/AR - Checks order for accuracy including prices

Delivery Note - Shipping Department - Ships order, updates delivered quantity (if different than ordered), adds memo for shipping details (Tracking, cartons Shipped etc)

Sales Invoice - Office/AR - Final check of pricing before invoice is committed and sent to customer.

Thanks!
