Here’s a step-by-step breakdown of what to do when your American Express account won’t sync with QuickBooks.
Sometimes the sync is broken due to changes in the account. Reconnecting it often helps:
Go to Banking tab in QuickBooks Online.
Locate your American Express account.
Click the Edit (pencil icon) and select Edit Sign-In Info.
Enter your Amex credentials again.
Hit Connect and wait for the update to finish.
This resolves login expiration or recent password change issues.
Browsers store cached data that may interrupt secure connections between QuickBooks and Amex servers.
Clear your browser's cache and cookies.
Disable extensions like ad blockers or VPNs.
Try logging in using Chrome Incognito, Firefox Private Mode, or Safari Private Browsing.
If Amex’s servers are under maintenance, syncing will fail no matter what you try.
Visit the American Express website directly.
Try logging into your account manually.
If it’s slow or throwing errors, wait a few hours and retry syncing.
