If you're dealing with QuickBooks American Express Not Syncing issues, you're not alone. Many small business owners experience these frustrating errors while trying to connect or update their American Express transactions in QuickBooks. Whether it’s an online sync failure, missing transactions, or duplicate entries, this issue can throw your bookkeeping off track. But don't worry—we’re here to help.

In this guide, we’ll cover everything from the root causes of the problem to actionable solutions to get you back on track quickly.

What Does “QuickBooks American Express Not Syncing” Mean?

When QuickBooks fails to sync with your American Express account, it means that the connection between the two platforms has been disrupted. This prevents the automatic import of your Amex transactions into QuickBooks, which can cause:

• Missing transaction data
• Duplicate or outdated entries
• Reconciliation errors
• Interrupted cash flow tracking

This issue can be incredibly frustrating, especially if you rely on real-time transaction updates.

Common Reasons Behind QuickBooks and American Express Sync Errors

Here are some of the most common causes of this sync issue:

1. Expired or Revoked Authorization

American Express connections require updated login authorization. If your credentials have expired or the permissions were revoked, syncing will stop.

2. Bank Feed Update Delay

Sometimes, Amex delays updating their feeds due to maintenance, which temporarily halts syncing.

3. Outdated QuickBooks Version

Running an older version of QuickBooks can result in compatibility issues with Amex feeds.

4. Incorrect Account Setup

Linking the wrong Amex account or connecting it to the wrong company file can trigger sync errors.

5. Browser Cache or Cookie Issues

QuickBooks Online relies on your browser. Cache and cookies can interfere with the syncing process.

6. Firewall or Antivirus Block

Security software may mistakenly block the sync process between QuickBooks and American Express.

How to Fix QuickBooks American Express Not Syncing

Let’s walk through some step-by-step solutions to resolve the issue:

Step 1: Reconnect Your American Express Account

• Go to Banking > Link Account
• Search for American Express
• Log in using valid Amex credentials
• Select the correct account and confirm

If the account was already connected, disconnect and reconnect it.

Step 2: Clear Browser Cache (QuickBooks Online Users)

Sometimes old cookies and cache block updates:

• Open browser settings
• Clear browsing data (cache and cookies)
• Close and reopen QuickBooks

Try syncing again after doing this.

Step 3: Update QuickBooks Desktop or Online

Make sure you’re running the latest version:

• For Desktop: Go to Help > Update QuickBooks
• For Online: It updates automatically, but you can log out and back in to refresh

Step 4: Verify Your Amex Credentials

Double-check your login and multi-factor authentication settings on the Amex website. Any changes might require re-authorization.

Step 5: Check for Duplicate or Hidden Accounts

Sometimes, an old or hidden Amex account can interfere:

• Go to Chart of Accounts
• Look for hidden or duplicate Amex accounts
• Deactivate or merge them if necessary

Step 6: Temporarily Disable Firewall/Antivirus

Your security software might block syncing:

• Temporarily disable your firewall
• Attempt syncing again
• Re-enable security settings after testing

Step 7: Manually Upload Transactions

If syncing still fails:

1. Log in to your Amex account
2. Download the transaction file (.CSV, .QBO)
3. Go to QuickBooks > Banking > Upload from file
4. Follow the prompts to import manually

This ensures your books stay updated even when sync fails.
