Dana Cooper Bermuda review for QuickBooks Online

very very difficult, been trying to connect for 10 hours. 3rd party and they don't help at all. They blame Shopify and QBO. QBO blames Shopify and Shopify blames QBO. A mess. why does Shopify and QBO advertise tthem, no accountability, endless exhaustive repeatitve tasks and typing.... how do I set up automating an invoice in QBO when there is a sale on my Shopify. can someone help me?
