It's not a matter of whether Quickbooks will support American Express Business Checking. It's about whether American Express will allow its business customers to link their business checking to Quickbooks and other software like Quickbooks. I heard it from the horse's mouth today (i.e., AMEX) as their customer support person confirmed that American express is not allowing AMEX business checking to link with Quickbooks or any other tools like it.
What I find very frustrating is that Quickbooks posted an update to the AMEX bank connections claiming that it was for security purposes and didn't advise that our link to the business checking would be broken for good. QB said that we would have until the first week of April to use the updated link. I thought I'd be proactive and update my connection and broke my connection to my AMEX business checking in the process.
I spent a considerable amount of time this morning in a chat with QB support to troubleshoot. Shouldn't QB know whether or not a bank will allow customers to link their account with QB?
At any rate, I'm posting this so that no one else spends considerable time trying to figure out this problem. AMEX customer support wasn't able to tell me if they will allow their business checking to link up with QB in the near future.
