Why is the Shopify POS system not meeting retail needs?

I share your frustration. I have been able to contact customer support and they are very polite and friendly AND NOTHING GETS FIXED. It is now fourteen days since the connector app sent data to the company file. I suspect that the part of the problem is that communications to the actual programmers is filtered to and from the help desk. It is sometimes hard to understand their requirements because their bookkeeping terminology is so different from QuickBooks or GAAP.
