Absolutely horrible after Jan 2026 update - You've asked us to disconnect and reconnect the app (which we have done 3 times). You claim a fix has been deployed (but no transactions are flowing through, and no invoices are created in QB). What is going on? Can you revert us back to the old app??

New update, now not - Hi, I updated the Bigcommerce (abbreviation BC) app in Quickbooks (Abbreviation QB) yesterday 13/1/25 (as prompted in QB). Today 14/1/25 none of my sales have synched and created invoices like they normally do. I can see that 5 orders have been imported from BC, only one of these have created an invoice. It seems like I should select them and click a button to move them to processing but I can't?

Great Support - Francis is really helpful getting our sync to work between BigCommerce and QuickBooks Online

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.
