Prior to setting up an American Express card with MineralTree, you should be sure to add the card in your accounting package. The MineralTree best practice is for your card to have its own GL account within your accounting package.

The Manual Card option allows for the marking of payments that were made outside of MineralTree.  Please see this Knowledgebase article on Manual Payments.
