    Setting up Sage 50 for credit card processing


    How do I set up Sage 50 for credit card processing?


    To begin processing credit cards in Sage 50 (formerly Sage Peachtree), you will need your Merchant ID (MID) and Merchant Key (MKEY). What is my Merchant ID Number? Where can I find my Merchant Key for Virtual Terminal Gateway?

    • Your MID is a 12-digit number and is always identical to your Virtual Terminal ID. For example, 134351655342.
    • Your MKEY is twelve alphanumeric characters long and always alternates letter-number-letter-number-etc., with capital letters. For example, A1B2C3D4E5F6.


    This information would have been sent in the 'New Merchant Information' email that is sent out when your account is created.

    Next, Sage Exchange Desktop must be installed: 


    Once Sage Exchange is installed, you are ready to enter your MID and MKEY into Sage50.

    From the 'Services' menu, select 'Credit Card Processing'.

    In the window that appears, please select 'Account Info'.

    Lastly, enter your 'Merchant ID' and 'Merchant Key', and then press 'Save'.
