If your customer is paying by ACH or credit card and you want to process the payment through Sage 50, select this button in either the Receive Money task window or the Receive Money at time of sale dialog from the Sales/Invoicing window. You'll be able to enter the ACH or credit card information (or use a card reader) within Sage Exchange.
The Process button is disabled if an authorization code was manually entered for a credit card for this transaction (Record button).
Note: If the payment was authorized using Sage Exchange, "(Sale - Approved)" appears on the Transaction Information window.
