# Working with Billing Plans

Billing Plans define the rate and frequency of subscription charges by means of Billing Periods, which include the Billing Plan’s subset of cycles of varying frequency, duration, and price. For example, a Billing Plan might be made up of an initial Billing Period that bills your customer $29.95 on the 5th of each month for three months, and a second Billing Period, that bills your customer $199.95 on the 5th day of every 6th month (bills twice per year), indefinitely.

The `BillingPlan` object encapsulates all Billing Plan information, including the current status of the Billing Plan, the number of Billing Periods contained within it, and any Entitlements that might be associated directly with the Billing Plan.

**Note:** Use of the forward slash character (/) in merchant identifiers is not allowed. See [Merchant Identifiers](Merchant_Identifiers) for more information.
