From Micro Division:
Microdivision PowerPack (For QuickBooks) is a utility that adds additional power to QuickBooks. PowerPack automatically remembers the prices charged for each customer while you create transactions such as invoices, sales receipts, and sales orders, so next time you create another transaction it will automatically insert the specific price for the selected customer. PowerPack can save the custom prices automatically, by importing from previous transactions, or you can set up lists manually. Microdivision PowerPack also allows you to set multiple shipping addresses per customer.
