Amex Not Syncing With QuickBooks? How to Fix It

Last updated July 2026

If your American Express charges have stopped flowing into QuickBooks, or the feed only brings in the primary card and leaves the employee cards out, you are not doing anything wrong. The same export-and-convert fallback covers any corporate card the feed misses. The Amex connection to QuickBooks is one of the most frequently broken bank feeds, and Intuit has reworked it more than once. Below is why it happens and the dependable way to get every charge into your books anyway.

Why does Amex stop syncing with QuickBooks?

Amex stops syncing with QuickBooks for a few recurring reasons: the connection has been migrated to a separate delegate-access provider that drops cards, the account is already linked to a different QuickBooks company, or Intuit has an open investigation into an Amex error. The same pattern hits other cards too, including a Chase business card that stops updating. American Express has changed how it connects to QuickBooks several times, and each migration has broken existing feeds for a stretch while users reconnect. When that happens, new charges simply stop appearing in the For Review tab even though the card is still active.

Because an Amex account can connect to only one QuickBooks company at a time, a feed can also go quiet if the same login was used to link a second company. The first connection stops updating without an obvious error message, which is easy to miss until a reconciliation will not balance.

Why are my Amex supplemental cards missing in QuickBooks?

Amex delegate access frequently syncs only the primary cardholder and leaves the supplemental and employee cards out of the feed entirely. This is the single most common Amex complaint in QuickBooks. You reconcile, the balance is off by hundreds or thousands of dollars, and the missing transactions all belong to the additional cards on the account. The feed is not designed to reliably pull every cardholder, so on a business account with several employee cards you can end up with a partial picture every month.

The monthly statement does not have this problem. American Express lists every cardholder's activity on the one PDF statement, so working from the statement is the surest way to capture the whole account.

How do I fix the Amex bank feed in QuickBooks?

Start by disconnecting and reconnecting through the delegate-access provider. In QuickBooks Online, go to Transactions, then Bank transactions, find the Amex account, and edit the connection. If it will not reconnect, sign in at americanexpress.com, open Account Services, then Security and Privacy, then Manage Partner Permissions, and remove the Intuit permission before reconnecting from the QuickBooks side. Reconnecting through the American Express (Delegate) option is what restores the feed for most people.

If charges are still missing after reconnecting, or the supplemental cards never come through, the feed is doing what it often does and there is no setting that forces it to behave. At that point the practical move is to stop fighting the connection and import the statement instead.

The reliable fix: import the Amex statement

The dependable way to get a complete month of Amex activity into QuickBooks is to convert the statement yourself. Download the billing period as a PDF from americanexpress.com, then turn it into a file QuickBooks can import. Our Amex statement to QuickBooks converter reads the PDF, captures every cardholder including the supplemental cards the feed drops, and exports a QBO (Web Connect) file for QuickBooks Online or an IIF file for QuickBooks Desktop. You review the charges in a table first, so nothing posts that you have not checked.

Import the QBO into a Credit Card type account, not a bank account, because a card is a liability. The charges land in the For Review tab ready to categorize, and because they come from the same statement you reconcile against, the month ties out cleanly. This also works for older periods. The Amex site only offers about six statements for download, so for catch-up bookkeeping you can convert the archived PDFs you saved and backfill the months a live feed will never reach. If what you have is a transaction CSV rather than a PDF statement, the QuickBooks side works the same way, and getting a credit card CSV into QuickBooks covers how the debit and credit columns need to map so a card month does not import backwards.

What about Amex on QuickBooks Desktop?

Amex bank feeds for QuickBooks Desktop have been even more unstable than the Online version, with the connection renamed and re-split more than once. Many Desktop users have given up on the live feed and import their activity instead. Convert each Amex statement to an IIF file and bring it in through File, Utilities, Import, IIF Files. It keeps Pro, Premier, and Enterprise current without depending on a connection that may break again next quarter. If you keep books for other accounts too, the same approach works for a checking or savings PDF through our PDF statement to QuickBooks Desktop guide.

Will the built-in QuickBooks Online PDF upload work for Amex?

QuickBooks Online now has a built-in AI upload that reads a PDF statement, including credit cards. It can work for a light Amex card, but it caps each file at 1,000 transactions and 350 KB, only runs on QuickBooks Online, and posts the transactions without a review step. For a heavy business card, several months of catch up, or QuickBooks Desktop, converting the PDF to a reviewable QBO file first is the more reliable route. There is more detail in our guide on whether QuickBooks can read a PDF bank statement.

Matching the symptom to the cause

Amex problems in QuickBooks look alike from the outside, so it is worth identifying which one you actually have before you start reconnecting things. Reauthorising a connection will not fix a card that the connection was never carrying.

Symptom	Likely cause	What actually helps
Primary card syncs, supplemental cards missing	The account was linked through Amex delegate access, which has a history of carrying only the primary card.	Reconnect using the primary cardholder's own credentials rather than a delegate login, and import statements for any card that still does not appear.
Feed stopped on a specific date and never resumed	The authorisation expired, or Amex forced a re-consent after a security or login change.	Disconnect and reconnect the account. Transactions from the gap will not backfill on their own and need importing.
Error connecting both a parent and a sub account	QuickBooks will not hold a parent Amex account and its sub account as two separate connections.	Connect one level only. Bring the other level in from statements.
Transactions arrive but stop several days short	Normal posting lag, not a fault, especially around a statement close.	Wait a full cycle before troubleshooting. If the gap persists past the next statement, then it is a real break.
Everything appears twice after reconnecting	The reconnect pulled an overlapping date range that was already imported.	Exclude the duplicates from the For review tab before adding them. Do not delete from the register.
Card is listed as not supported	Certain Amex products, including some corporate and co-branded cards, are not covered by the QuickBooks feed at all.	There is no connection fix. Statement import is the only route, and it is the permanent one.

The pattern worth noticing is that three of those six rows have no connection based fix. When a card is unsupported, when the delegate connection will not carry supplementals, and when history predates the feed, the transactions have to come from the statement itself. That is why firms with several Amex cards often stop fighting the feed for those accounts and just build a Web Connect file from the statement each month, which takes less time than the average call to support.

Frequently asked questions

Why is my Amex not importing all cardholders into QuickBooks?

Amex delegate access often pulls only the primary card and skips the supplemental and employee cards. There is no toggle that forces all cards through the feed. Converting the monthly PDF statement, which lists every cardholder, and importing that QBO file is the way to capture the full account.

How do I reconnect Amex to QuickBooks?

Disconnect the existing connection in QuickBooks, remove the Intuit permission under Account Services, Security and Privacy, Manage Partner Permissions on americanexpress.com, then reconnect from QuickBooks using the American Express (Delegate) option. If charges are still missing afterward, import the statement instead.

Can I get old Amex transactions into QuickBooks?

Yes. The Amex website usually offers only about six statements to download, but you can convert any Amex PDF you saved, including older periods, to a QBO or IIF file and import it. That is the standard way to backfill months a live feed cannot reach for catch-up bookkeeping or an audit. On QuickBooks Desktop the equivalent import file is IIF, which our PDF to IIF converter produces.

Does American Express work with QuickBooks Online?

Yes, American Express connects to QuickBooks Online through the American Express (Delegate) connection, but the feed is known for dropping supplemental cards and stalling after Amex security refreshes. When the live connection is incomplete or down, converting the monthly PDF statement to a QBO file and importing it brings in every cardholder and every charge for the period, which is why many bookkeepers use the statement import as their primary method rather than a fallback.

How do I stop duplicate Amex transactions in QuickBooks?

Duplicates usually appear when a live feed and a statement import both bring in the same charges, or when you reconnect the feed and it re-downloads a period. Import only one source per date range: if you convert and import the statement for a month, do not also pull that month through the feed. Because a QBO file carries a unique ID on each transaction, QuickBooks blocks re-importing the exact same file, so sticking to statements for a given period keeps the register clean.

Why does my Amex say it is not supported in QuickBooks?

An "account not supported" or "cannot connect" message on Amex usually means the specific card product or a business account type is not covered by the delegate feed, or Amex has changed its connection on the back end. There is no setting on your side that fixes an unsupported account. That puts you in the same position as anyone whose QuickBooks bank feed is not working for structural reasons rather than a temporary glitch, and the response is the same. The dependable path is to download the PDF statement, convert it to a QBO file, and import that, which works regardless of whether the live feed supports the card. The steps are the same for any card issuer, so follow the guide to converting a credit card statement PDF to QuickBooks.
