I use Quick Books at work. It's a great accounting program but it lacks in some areas of the inventory part and unfortunatly LIFO or FIFO are the areas lacking. One thing you can try is making the item an inventory part -- with no cost -- and then do new parts under the sub item with each of the new prices.

Their HELP section can usually clear up questions but if you need any help -- let me know and I'll see if I can answer you.

Also a really good book to help you out is "The Complete Idiot's Guide to QuickBooks & QuickBooks Pro 99". It was written by Gail Perry, CPA. and put out by Alpha Books.
