This plugin is exactly what I needed. My store and QB settings are quite complicated, so it was really important for me to have extensive control over what is synced, how it's synced, and when it's synced. This plugin provides so many optional controls and settings, that I was able to set it up exactly as I needed, and now I have all of my data syncing over perfectly. I never thought it would be possible to automate my data transfer, but thanks to this plugin I can - and I've saved so much time.
