# Creating a service period
<a name="creating-service-period"></a>

Service periods can be added to any channel relationship using Partner Central Channel Management.

1. **Initiate the service period** – Channel Partners create service period invitations on specific relationships, specifying either minimum notice requirements (14, 30, or 60 days) or fixed-term commitments (60-365 days).

1. **Customer notification** – A channel handshake is automatically created and the end-customer's AWS management account receives an email notification with a unique response link.

1. **Customer review and response** – An authorized user from the customer's AWS management account must:
   + Access the invitation using the unique link provided in the email
   + Sign in to their AWS Console to review the proposed service period terms
   + Accept or reject the service period agreement

1. **Service period activation** – Once the customer accepts the channel handshake, the service period becomes active and governs the billing transfer relationship according to the agreed terms.
