## 1 Introduction
This document guides you step-by-step process of onboarding SAP Subscription Billing including the Price Calculation service.
Once you've received an email from SAP welcoming you to SAP Subscription Billing, you can start with the first steps.
The technical setup includes the creation of a tenant. Only users with an Administrator role for the global account can create tenants. At first, only the recipients of the welcome email have this role. If someone else needs to create a tenant, one of the email recipients must add the relevant user as Administrator for the global account. This is described in the section Add Administrators to Global Account [page 22].
See also the SAP Business Technology Platform (SAP BTP) documentation for an overview of all administration roles: Role Collections and Roles in Global Accounts, Directories, and Subaccounts.

## Cloud Availability
We recommend that you go to SAP for Me and add the e-mail addresses of employees of your company whom we can contact with Cloud Availability notifications relating to SAP Subscription Billing. You do this under Systems &amp; Provisioning .
##  Tip
Ideally, enter the e-mail addresses of your fellow employees who can work with us in critical situations without delay. For more information, see Get Notified .
## Booster
Decide whether you want to use an automation wizard called 'booster' for the onboarding of an SAP Subscription Billing tenant, or if you want to follow a manual step-by-step guide.
##  Note
The booster has some settings that need to be configured carefully, for example regarding subaccounts. Please read the information on the booster carefully.
For the next steps, see:
- Set Up Using Booster Automation [page 7]
- Set Up Using Connectivity Automation [page 14]
- Set Up Using Manual Steps [page 20]
##  Caution
We strongly recommend that you do not unsubscribe from the Price Calculation service once you're actively using configured prices. Unsubscribing results in the deletion of all pricing data 1 day later which would result in inconsistencies within SAP Subscription Billing.
## SAP BTP Environment
SAP Subscription Billing runs on the Cloud Foundry environment. For more information, see Cloud Foundry Environment in the SAP BTP documentation.
## Data Centers
SAP Subscription Billing can be run in the following data center locations (SAP Business Technology Platform regions):
- Europe (Frankfurt)
· Europe (Frankfurt) EU Access You can include the option EU Access in your contract, in which case processing of personal data is restricted to EEA/Switzerland, provided you create your subaccount (tenant) in the region eu11 . Creating a subaccount in the region eu11 without the option active in your contract is not sufficient to restrict processing to EEA/Switzerland.
- US East (VA)
For more information, see Regions in the SAP Business Technology Platform documentation.
##  Note
Paths in the SAP Subscription Billing documentation usually refer to the region eu10. This is just an example region and can be replaced with your own region.
You cannot migrate data in existing tenants from one data center to another.
