Sinister Labs

We tried them all and this is the best QB/Shopify integration app available. The support team is great as they respond very quickly and are open to implementing feedback.

As with any app there is always the potential for problems due to conflicts with other apps and customization. Ours was one of these rare cases and this app was conflicting with another app we had installed. We emailed support and Shane dove right in and remedied everything. He went above and beyond to ensure our problem was resolved in a timely manner. The app is amazing and works just as we expect it to. I highly recommend the app for it's functionality as well as the amazing team that supports it!
