Thanks Wildbar. I vaguely remember messing around with the Export Utility when it was first introduced, but that was easily 15 years ago when I was working as a programmer for a Micros dealership. My current client is using the built in quickbooks interface, and wants to know if it can be modified.
I actaully just dug up an old Doc Cafe, (Res 3000!), cd while cleaning out a file cabinet, so I'll take a look and see if that has anything.
