QuickBooks Online

The Shopify/Quickbooks app works decently for a very simple online store and accounting setup. I've had no issues with duplicate transactions, though the lack of support for cash transactions is incredibly frustrating.

This is crap...I was happily paying a subscription fee for the previous version. This one has completely screwed all of my reporting.

It does not pull in orders that are not from the "Online Store" sales channel. This channel selection is not available as part of the configuration. I even upgraded my QBO account thinking I needed to add another sales channel (a term used in both systems, but mean different things).

Since it does not pull in all my sales, it's useless.

BEWARE!! dont connect it to your store. Its impossible to disconnect even when calling quickbooks and following all the steps. Save yourself from an accounting mess, it double records transactions.

this does not pull in sales receipts with product info. So if you track inventory in quickbooks, it will not reduce your inventory when you sell an item. Unfortunately I disconnected the old version from OneSaas and now I am not able to reconnect OneSaas. What a disaster!
