QuickBooks Online

Even though it says this app isn't compatible with my shop, I've had it installed for awhile now. It's not the easiest thing to configure, and for awhile I had daily error notifications that I could not fix, making a bit of a mess in QBO for me. I finally reached out to customer service for help after my accountant couldn't determine the issue or fix. I gave them access to my shop and they configured everything for me and then when I had another error message, they fixed that as well. I'm super pleased with the help they've provided me, and the app service overall. If you're using QBO and Shopify, this is a great solution.
