I have an Access 2000 program handling the receiving of goods in the company. I need to Export Inventory Items and Quantities to Quickbook (enterprise 2007?). I have a good handle on the Access program, but know nothing about quickbooks. Can this be done? What would I need for it?
Google is your friend here. Quickbooks has some primitive import capabilities, but there are a number of small products that do what you need. This guy seems to have some pretty good stuff. Essentially there are a couple of different text formats (QIF and OFX if memory serves) that are used for Quickbooks import, the problem with them is they don't do much error checking. There is also a Quickbooks SDK which allows you to make calls using COM (yum) to import, and that does full error checking (it actually calls into a running version of Quickbooks), but is probably overkill for what you want.
Take a look at the QuickBooks SDK. If you want something simpler to work with, QODBC (with the write capabilities), while not free, will probably be simpler to work with for Access.
Look into the QuickBooks SDK, a free download from Intuit. It provides a COM object interface or XML interface to all of the QuickBooks data. Additionally, if you need to do this over a WAN, you can use the QuickBooks Web Connector to talk to QuickBooks asynchronously over a WAN.
QuickBooks integration is not a trivial thing to accomplish. There are many gotchas. Your best friend will be the Intuit Developer Network forums.
You do not want to use QIF, QFX, or IIF exports. They are deprecated formats which can cause data corruption. Additional information about various methods of integrating with QuickBooks can be found on this integration wiki page and on this QuickBooks integration wiki.
