Has anyone here done any custom QuickBooks development? Looks like I’m going to be doing quite a bit of it in the near future, and just was looking for any help and/or advice on the best route to take.
I see there is an “official” QuickBooks SDK, and then there is something called QuickBooks IPP, but I’m trying to figure out if that is just for QuickBooks Online or if it also works with the desktop/network QuickBooks programs.
Any help and/or suggestions would be appreciated. I plan on doing this development in .NET/WPF with Elements/Oxygene.
Thanks!
