# Join via CTA

Some customers have certain organizational and/or security level constraints that require a different onboarding process. For those customers we can onboard them via a Consent To Assign Agreement (CTA). A CTA is a process for moving the account ownership and billing of the organization management account from the customer to Pump.\
\
**Step 1: Discovery**

* Pump will do discovery on a call with the potential customer to determine if CTA is right for them. This will be at Pump's discretion and is not available to all prospects.
* The customer will deploy the read-only stack and run the estimate to determine if they'd be interested in joining Pump.

\
**Step 2: CTA**

* Once the customer is ready to join Pump, Pump will present them with the CTA agreement.
* The customer will update the root user email address of the management account to a provided email address.
* Pump will update the billing details of the management account to Pump's details.

\
**Step 3: Onboarding**

* The customer will deploy the auto-pilot stack to allow Pump access to their billing and savings.
* That't it!!
