mixed review - the old qb app was great, the new update is forcing payment import which we do not want. we swapped to the onesaas app, unknowing that it is just the old quickbooks app. It worked great once we swapped, however, it is now forcing an update to the new one saas app, which mimics the new quickbooks app. Again, trash for us as we don't want to import payments. in 3 months they refuse to add a button choose if you want to import payment. 10 days we have had no sync as we cannot import payments. The only bright light was "Chelle" at on saas, she spent oveer 2 hours online with me , and was able to reintegrate the old onesaas app and get everything imported without payments. Very patient and listened to what i needed, how long it will work i don't know, but all we need is to do the same as the old quickbooks app and current one saas. Give us the ability to choose if we want to import payments.

Update Not Working, Support Link Broken - Jan 2026 update not working. Customer addresses not downloaded, product details not downloaded, shipping missing from orders. Trying to contact support but links are broken. Please return to the legacy version. That one worked.

Not fit for purpose - This version of Quickbooks integration is not fit for purpose. Its caused double entries and incorrect currencies in quickbooks. Dont expect much support from BigCommerce either, they pass it on to Quickbooks.

Horrible - Quickbooks has become one of the biggest disappointments imaginable. Several months ago they launched a new. version of this app. It was broken. After over a week of back and forth they allowed the legacy app again. It worked again. Now, they released a January 2026 update. It appears to be the same app they released last time WITH THE EXACT SAME ISSUES AND ONCE AGAIN, IT DOES NOT WORK. If you are considering an accounting system or ERP for your e-commerce business look at NetSuite. Quickbooks makes random updates without notification that will negatively impact your business. This integration app is only one of many examples of what a failure this is becoming. If I could leave less than one star I would. Unfortunately a rating is required.

Great customer service - Sam was great. Understood my issue with the new sync and helped get it working again. Thank you!

Jan Update Ruined App - App has worked flawlessly since 2019 and recent update just prevented integrations, order & inventory syncing, etc. Now creating more work by needing to manually edit orders and import them. I have been trying to work with a representative and so far nothing has changed at all. I have disconnected and reconnected multiple times to no avail and customer support seems to think they are finished with helping. Please go back to previous and I can leave a 5 star!

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.

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, 2nd time in 3 months - Zero Stars...Once again, QuickBooks have attempted to upgrade their App, no longer works!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.
