Yeah, I've got an app. that pulls info. from a sales website down nightly and pushes it into QB's via the COM interface that QuickBooks has. It's A LOT better than the IIF approach.

I found it pretty easy to use; if you've use COM before (eg. automating Word, or Excel, third party controls, etc) it should be pretty straightforward. Most of the samples are in VB, though (the syntax is close to VFP, so it's relatively easy to translate it). It has it's quirks, like anything. Depending on how complex the info you are importing is, you may or may not run into them.

I think there is some sample code in the downloads section here...
