Hi amobgirl29,

I'm happy to shed light on connecting AMEX accounts to QuickBooks.

For the AMEX Open/Business account type, you can only connect one account under the same login. For Personal or Corporate account types, you can connect multiple parent accounts using the same credentials. However, for the parent-subaccount setup of Personal and Corporate accounts, you can only connect the parent or the sub-accounts (not both types).

Which type do your boss and his wife have? Are you getting error codes?

Alternatively, you can manually upload your bank transactions.

Feel free to send an update about your attempt to connect your boss's and his wife's AMEX accounts.
