I am interested in feedback of those who use QuickBooks Pro. Currently, I have v6 and I have not upgraded to version 2005. I don't know if it is worth the cost, but eventually I have to pony up and get it.
While I don't use QB myself, I am developing a point-of-sale application to extend its functionality. The application will use QB exported data at the POS. It will then export back to QB the sales data and new customer information.
I have read of several people having problems with it. I have had a few crashes myself, while testing it with my app, but that was probably from feeding it data in unexpected formats.
I would like to hear of good and bad experiences with it.
