QuickBooks Online

2025 Review - Been having some tech issues due to myself messing around with the set up, going back and forth trying to change invoice numbers, so the sync stopped. Sherwin has been very helpful and solved my issue by providing guidance on each step of the instruction, also very patience with my questions, happy with the app, happy with the support, issued solved :)

2026 Review - Had some issues with the new integration app, Sam was able to helped me out step by step to make the changes and revert back to the old setting that I had as it works better for me at the moment, support is super on point, patient and provides clear instructions, was able to resolve my issue

I use this app whenever Falcon PEV Shopify invoices cannot sync into QB and the Oneseas support staff, Joe are so helpful and solve my problems. Thanks a lot for the immediate assistance again.

Initial support was great, but once we encountered an area that required real technical support, they fell short. No one took ownership of the problem, and we went round and round in circles with no resolution. They lack a methodology for escalating issues. Therefore, if you have both D2C and B2B customers, their syncing tool cannot differentiate between them and place them in the correct accounts in QuickBooks.

This has been pretty easy to set up. After my first sync, there were some issues. I chatted with Sherwin, and he fixed everything really quickly, and explained what was done, and what I need to do to keep it going smoothly (just unchecked a box, really). This app works and works well. Definitely worth it.

4 years later and still great service and really helpful app. This time, I had a problem syncing because I had changed from inventory to non-inventory all my products in QBO. Sam got me all set up and cleared all the errors in one go.

UPDATED: Spoke with Sam today about the connector app, and he was incredibly patient and helpful in resolving my issue. Thank you to Sam!

UPDATED: The onesaas shopify connector app used to be seamless until they had an "upgrade". Although there are definitely some issues with it, the customer support they provide is top notch. Jasmin went out of her way and even offered to stay after her shift to help me with some sync issues. If I had to choose an app with problems that had great customer support versus an app that worked well but had terrible customer support, I'd choose the former and would hope they all were as good at their job as Jasmin. Jasmin is a difference maker. Thank you!

It does a fantastic job of helping me keep my invoicing, payments, and inventory in sync with my storefront and my accounting. Sherwin helped me to today with an issue that was solved professionally and quickly!

The new "upgraded" connector has more limitations than features. It has completely messed up with our accounts and we had to revert all sales receipts that it auto-posted into Quickbooks. We have now made decision to stop syncing which left us with no sales imported into Quickbooks since 2nd September. Please revert to original app or fix the new one asap! I have already spoken to one of your experts who informed me that the new app is still in development... how can an app be launched without months of testing and answering feedback from users???

In the process of setting up Quickbooks Online for my business. Still learning, I needed some help to get my orders from Shopify to sync. I got great, quick and helpful service from Sherwin!
EDIT:
Got some great help from Rods today! Allowed for blocked transactions (no name customers) to sync from Shopify to QuickBooks.

This is the exact app we needed to sync our Shopify data with QBO. There is a good amount of control so you can set exactly what and when it get's synced over. We are able to just sync unpaid orders in Shopify so we are able to invoice in QBO. When I had an issue with the connector showing an error I used the live chat support and Clarisse was able to quickly fix my issue. Would recommend.

Update: Needed help again and David was able to fix our issue in less than an hour of writing an email.

Update: Sherwin solved our issue in a quick simple chat

Quick response and support from David on chat. Identified my set up issue immediately. Thanks again!!

Ben helped on a second issue and was also very quick and helpful

Update: I've now use the app for 2.5 years and have been happy with the quick support. Sherwin was able to provide quick answers to my questions today

Update: Sept 3, 2026 - New integration isn't working. Very frustrating

If there was another option i would use it.
Unfortunately QBO is the only accounting software that syncs with Shopify.
Customer service is generally terrible.
Mostly they close the chat and leave you to explain the same thing to another rep for another 15 mins.
Some features are very stupid.
You cannot send statements to more than 50 customers at a time?
Stupid.
Often it will sync duplicated customer details so you will have to reach out to the admin team to delete and resync individual invoices which again takes too long as the teams priority is giving nice fluffy responses first, then doing the job!!!!!!! Frustrating.
I find myself having to chat with the QBO team WAY more than i Should for what is a very limited use of there software. I need to sync and send statements, thats pretty much it.
Why do i always spend so much time with your support team for something so basic???
And no, the customer information been synced is not any different.
