# Billing Groups

> Combine multiple subscriptions into a single invoice

Billing groups allow you to combine multiple subscriptions into a group. This way, subscriptions are billed together and summarized on one invoice.

## Create Billing Group

<Steps>
  <Step title="Open Billing Group Form">
    Click on "Create Billing Group" in the billing group dropdown.
  </Step>

  <Step title="Configure Billing Group">
    Assign a unique name to the billing group. This is only used internally and is not visible to customers.

    Select under "Timing":

    * **Beginning of Month**: All subscriptions are billed at the beginning of the month.
    * **End of Month**: All subscriptions are billed at the end of the month.
    * **Beginning of Year**: All subscriptions are billed at the beginning of the year.
    * **End of Year**: All subscriptions are billed at the end of the year.
    * **Custom**: All subscriptions are billed on a specific day of the month.

## Add Subscription to Billing Group

When [creating a subscription](/en/guide/subscriptions/create), you can select a billing group under the advanced billing details. All subscriptions in the same billing group are billed together.

<Tip>
  Billing groups are customer-specific. You can create separate billing groups for each customer.
