Hello @LeizylM ,

That doesn't really answer my question.  What I wanted to know is; once we did the very first data sync between QBPOS to QB desktop financial, 11,000 customers were uploaded from POS to DF.  I want to remove the 11,000 customers from the DF.  Is there a way to delete these customers en masse or do they have to be deleted one at a time. (from the desktop financial software not POS) I'm slowly going through the customers on the POS side and unticking the "Use with QuickBooks" box.

Thanks
