Shopify to QuickBooks not posting right since the new connector? What changed, and how to check a month
Updated 2026-10-15 · by Hieu Tran, written with AI agents and checked against the sources below
Intuit moved Shopify stores off the old OneSaaS connector onto a new connector inside QuickBooks Online. Since August 2026, merchants have reported sales split across new income accounts, orders that never arrive, duplicate invoice numbers and wrong VAT. Here is what changed according to Intuit, and how to find out which of your orders are affected.
It lists orders missing from the books, posted twice, or posted with a different total or tax, plus the income accounts your sales went to. Files stay in your browser. It's a check, not accounting advice.
What Intuit changed
The new connector lives inside QuickBooks Online: All apps → Accounting → Integration transactions.
It imports individual transactions instead of one summary sales receipt per payout period, as OneSaaS did.
For Shopify it creates default accounts for fees, adjustments, reserves, tips, gift cards and disputes. Intuit asks you to check them against your chart of accounts.
It can't import orders as unpaid, syncs every few hours, and doesn't sync inventory both ways yet.
Tax codes are mapped in the connector's settings, and you may need to set up product and customer matching again on the first sync.
You choose a sync start date, up to 12 months back. Intuit says to pick one that doesn't overlap data already imported.
What merchants report since the switch
From 1–3★ reviews of the QuickBooks Online app on the Shopify App Store, September and October 2026:
Revenue split across two income accounts in the middle of the fiscal year, with every sale under a generic customer and item.
No choice between invoice and sales receipt any more.
Zero-value sales not sent to QuickBooks.
Zero-rated sales entering as standard-rated (UK VAT).
Duplicate invoice numbers.
Transactions not syncing because of a tax setting, delayed since 30 July.
Check one month by hand
In Shopify, export the month's orders (Orders → Export, CSV, filtered by date).
In QuickBooks, run Transaction List by Date for the same dates and export it.
Match each Shopify order number to a transaction. Check a few by hand first to see which column holds the order number.
List orders with no match. Look at zero-value, unpaid and cancelled orders first.
List order numbers that appear more than once, and invoice numbers used for two different orders.
Compare the total and the tax of each matched order. Look out for zero-rated orders posted with standard VAT.
Group the posted sales by income account to see whether revenue moved to a new account mid-year.
Fixes to try first
Wrong tax: check the tax mapping in the connector's settings before the next sync.
New accounts: compare the connector's default accounts with your chart of accounts and remap them.
Doubles: make sure only one app posts Shopify sales (the old connection, the new one, or a paid sync app), and that the sync start date doesn't overlap older imports.
Before deleting or changing posted transactions, check which ones are matched to bank deposits or included in a reconciliation, and ask your bookkeeper.
