Old version was great - I used the QB app for many years and had no issues. The recent update of mid-November caused a lot of issues with my Big Commerce integrations. Fortunately Francis at QB was able to get me back to the legacy version while they make fixes to the update. Everything is back to normal and good working order. Francis is a hero. I wish she was the first person I dealt with when the problem started. That would have saved me about 30 emails, 10 chat sessions, and three long phone calls.

Great Customer Service - Francis was very helpful with my integration and answered all my questions well and also resolved some little issues through the development team to help keep my account clean of old integrations. Easy and seemless walkthrough

It is not worth a 1 star, that is too generous - I would not recommend this app for anything other than removal as an option in this app store. It does not adhere to the basic system-of-record principles for data exchange between BigCommerce and QBO. The concept of this app is perfect, but it is just not ready for prime time.

Great support - Francis was a great help with a quick work-around to keep our store syncing during the busiest time of the year.

Lack of Support - Begging for assistance addressing their integration issues and it has been nearly impossible to receive any assistance. Only respond via email at the end of the day giving repetitive instructions to uninstall and re install, No one to speak to via phone or real help at all. I highly recommend using alternatives solutions with better support and less bugs.

Lack of OneSaas Support - Begging for assistance addressing their integration issues and it has been nearly impossible to receive any assistance. Only respond via email at the end of the day giving repetitive instructions to uninstall and re install, No one to speak to via phone or real help at all. I highly recommend using alternatives solutions with better support and less bugs.

Integration issues - Ever since Intuit/OneSaaS took full control of this integration, it’s been a nightmare. The new version no longer functions correctly — it only imports partial data from BigCommerce into QuickBooks Online. Shipping charges don’t sync, so invoices and payments never match (payments include shipping, but invoices don’t). Customer addresses are no longer imported, guest checkouts are skipped entirely, and even check payments are marked as “paid,” creating constant reconciliation issues. I’ve spent the past month manually fixing every transaction, adding addresses, and adjusting invoices one by one. BigCommerce support has been great but can’t help since Intuit now owns the app, and OneSaaS has yet to fix these problems despite multiple tickets. This rollout was irresponsible and has seriously disrupted my accounting workflow.

Great Support - Nick is awesome. Has now helped me twice with sync issues. So friendly & helpful.

Integration Broken - After the update on 6th of October the QuickBooks app no longer integrates. Was working perfectly prior to the update, was just told it is now back online and uninstall and reinstall and it will work, I have followed the process and still not working.

Integration Broken - The app updated and the connection has been lost from BigCommerce to QBO, nothing will update. On with the chat yesterday with no resolution. Allegedly in 24-48 hours the legacy app will be be re-introduced and the connection restored. It has been down all week.
