Thanks, you explained why I am doing what I am doing to Jane.  I am doing what you described, I just have been doing it all at once.  I hadn't thought about editing the invoice later.  The spreadsheet I use, I enter in the vendor list price and qty I ordered, then use formulas to create an extended cost per unit adding in the shipping and duty costs based on a % of the total order for each item.  Then I enter it once into QB, with the clearing accounts as you described.
