# Creating a new customer

To create a new customer:

1. Open the **Customers** list in the Stigg app and click **+ New customer**.
2. In the modal, fill in the customer details:
   * **ID**: auto-generated by Stigg. Use this value to reference the customer in your application. Override it only if linking an existing customer. *(The customer ID is immutable.)*
   * **Name**: optional display name.
   * **Email**: optional billing email address.
3. Click **Create** to confirm.

<Note>
  In most cases, new customers should be created using the Stigg server SDK.
