Connect Vantiv (Litle & Co.) to Advanced Billing to process credit card transactions.
Important: Vantiv (Litle & Co.) isn't available in the standard gateway picker by default. Contact Maxio to request access for your site.
Vantiv emails your User ID, Password, and Merchant ID directly to you.
To use the pre-live environment, enter your real User ID, Password, and Merchant ID. To use the sandbox environment, leave the User ID and Password fields blank and enter 101 for the Merchant ID.
Each currency you want to use with Vantiv requires a separate account.
