QuickBooks Sync by MyWorks

MyWorks has been a lifesaver when it comes to importing ALL data from Shopify into Quickbooks Online. They respond quickly to email support requests, their customer service team is knowledgeable and always willing to tackle the issue, no matter if it pertains to sales tax sync, purchase orders entered on a third party app, or partial return receipts straight from Shopify. If something does not sync correctly, they have been very helpful in getting the issue resolved in a timely manner. Definitely recommend over "free" apps that end up costing time!
