# Billing Plan Periods Pane

In the Billing Periods pane you can define multiple Billing Periods. For each, set a cycle length, which defines the length of the billing period; and the number of times to repeat the cycle, which defines the length of the subscription. Cycle length can be days, weeks, months, or years. Customers are billed on the first day of the billing cycle. Billing Periods are active sequentially, according to their order in the Billing Plan. The first Billing Period in the list will be in effect when the subscription is first purchased, and it will remain in effect until it completes its defined number of cycles.

| Field | Guidance | Relevancy |
| - | - | - |
| **Cycle Length** | Cycle length defines the duration until the next billing date. Enter a number and select a time frequency (Days, weeks, Months or Years) from the dropdown menu. | Required |
| **Repeat Cycle** | Enter the number of times to repeat the cycle. Select **Unlimited** to have the billing cycle repeat indefinitely, or select **Times** and enter a value. For example, a **Repeat Cycle** value of **4** with a **Cycle Length** of **3 Months** defines a one year subscription that bills four times. | Required |
| **Trial Period** | Trial periods are free and override the price of the billing plan and/or product. If you wish to set a free trial period, use the toggle to select **Yes**. Then add a second billing period. | Optional |
| **Email On First Bill** | Select **Yes** to generate a customer notification on the first billing date of the period. If the Billing Period is free, select **No** to prevent your customer receiving contradictory billing notices. Default value is No. | Optional |
| **Email Before Expiration** | To send a warning notice indicating that the subscription is set to expire to your customers, enter a value for the number of days before this billing period ends. If you leave this field empty, no expiration notice is sent. | Optional |
