Intuit has not supported iif for many years. They have also threatened to drop it for years, however every new version of Quickbooks, including 2008, has had it. There are just too many applications out there that use it.

If the iif files are properly formatted, which QBI does, there should be no problem. There are tens of thousands of people using QBI, and I've never heard of a corrupt company file occurring or any kind of data validity problem happening. QBI does have to be set up properly with the right company accounts and settings, but that's going to be the same regardless. So, users should have no reservations about importing iif files. However, that's not to say that there aren't advantages to using the SDK, and I plan to add XML file output capability to QBI 4.0.
