Hi there WCS -Lou,
Thanks for reaching out about accepting American Express payments. For further assistance with setting that up, you would need to reach out to the QuickBooks Payments support team outside of the Community. They'll be able to assist in getting that set up so that you can accept payments from that payment method. You can reach them using these options:
Schedule a Callback or start a Chat: click (?)Help in the upper right in QuickBooks Online > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
Phone: dial 1-855-253-1536
If you have any other questions, feel free to reach out here.
