Merchant accounts are configured by channels.  

A Merchant may have one account that is for their Brick and Mortar or POS system, a second account for their Mail order or Telephone order (MOTO) customers, and a third for use with their eCommerce (ECOM) customers.

The Dealer Change Form, or DCF, will associate the specified account (POS, MOTO, ECOM) with a Vantiv dealer.  

We may choose to allow a Merchant or their third party developers access to the software in advance of the DCF paperwork being completed, but live usage of the software is only permitted when the ECOM account in use has been appropriately associated with our systems at Vantiv. 

The paperwork is short, easy to fill out and can usually be processed by Vantiv withing 24-48 hours.
