With **different billing frequencies**, you can assign an independent billing cadence to each add-on and usage-based billing product in a subscription. This lets you align charges with how your customers actually use and pay for your services. For example, you can bill a base plan annually, invoice an add-on quarterly, and charge a usage-based product monthly; all within a single subscription. > [!TIP] > Good to know > > - Each component with a different billing frequency generates its own separate invoice. Alternatively, you can sync a component to the plan's billing cycle so it appears on the same invoice as the plan. > - The price defined on an add-on or usage-based billing product always refers to its own billing period, not the plan's period. > - Existing subscriptions without component-level frequencies are not affected by this feature. --- ## Before you begin - You have an active plan with a billing frequency configured (see [Plans](/frisbii/docs/plans#decide-on-the-frequency-of-billing)). - You have created or are creating an add-on or usage-based billing product (see [Add-ons](/frisbii/docs/add-ons) and [Usage-based billing](/frisbii/docs/usage-based-billing)). - Understand the [compatibility rules below](/frisbii/docs/different-billing-frequencies#compatibility-rules) before configuring frequencies. --- ## Compatibility rules Not all combinations of plan and component frequencies are valid. Frisbii Billing enforces the following rules: > [!CAUTION] > 🚫 **Limitation** > > A component's billing frequency must be **equal to or longer** than the plan's billing frequency, and must align perfectly with one or more plan billing periods. For example, a monthly plan supports monthly or yearly add-ons — but not weekly ones. The table below shows which combinations are supported: | Plan schedule type | Daily component | Weekly component | Monthly component | Yearly component | | --- | --- | --- | --- | --- | | Daily | ✅ | ✅ | ✅ | ✅ | | Weekly (fixed day) | ❌ | ✅ | ❌ | ❌ | | Monthly (start date, fixed day, last day) | ❌ | ❌ | ✅ | ✅ | | Yearly | ❌ | ❌ | ❌ | ✅ | --- ## Configure a billing frequency on an add-on 1. Go to **Configurations** → **Product Catalogue** → **Add-ons**. 2. Click **Create add-on** or open an existing add-on. 3. In the add-on form, click **More options.** Click on **Billing frequencies** and Confirm. 4. Set the billing frequency: - **When do you want to bill?** — choose Daily, Weekly, Monthly, or Yearly. - **How often do you want to bill?** — enter the interval length (e.g. *3* for every 3 months). 5. Click **Save**. ![](https://cdn.document360.io/b84e1b5d-2ba6-4465-8c62-fb45a2f31314/Images/Documentation/image-CTTS05Y1.png) > [!TIP] > **Good to know** > > Changing the billing frequency on an add-on after it has been applied to a subscription does not affect existing subscriptions. Only new subscriptions created after the change will use the updated frequency. --- ## Configure a billing frequency on a usage-based billing product 1. Go to **Configurations** → **Product Catalogue** → **Usage-based billing products**. 2. Click **Create product** or open an existing product. 3. In the product form, click **More options**. Click on **Billing frequencies** and Confirm. 4. Set the billing frequency: - **When do you want to bill?** — choose Daily, Weekly, Monthly, or Yearly. - **How often do you want to bill?** — enter the interval length (e.g. *3* for every 3 months). 5. Click **Save**. ![](https://cdn.document360.io/b84e1b5d-2ba6-4465-8c62-fb45a2f31314/Images/Documentation/image-2J7RIEV0.png) --- ## Add a component with a different frequency to a subscription ### Usage-based billing product 1. Go to **Subscriptions** and open the subscription you want to edit, or create a new subscription. 2. In the **Usage-based billing** section, click **Add usage-based billing product**. 3. Select the component. If it has a billing frequency that differs from the plan, you cannot save the configuration. 4. Click **Submit** to save. ### Add-On 1. Go to **Subscriptions,** open the subscription you want to edit, or create a new subscription. 2. In the Add-On section, click **Add Add-On**. 3. Select the component. If it has a billing frequency that differs from the plan, you cannot save the configuration. 4. Click **Submit** to save. > [!CAUTION] > 🚫 **Limitation** > > If you switch the plan on a subscription to one with an incompatible billing frequency, any incompatible add-ons or usage-based products are automatically removed from the subscription. Frisbii Billing warns you before this happens. --- ## Invoicing with different billing frequencies When a subscription contains components with different billing frequencies, Frisbii Billing generates invoices as follows: - By default, each component with a different billing frequency is invoiced on a **separate invoice** on its own billing date. - If a component's billing date coincides with the plan's billing date, it can be included on the **same invoice** as the plan. - Each invoice line item for a component shows the **service period (from – to)**, so your customers and finance teams can validate exactly what is being charged. --- ## Subscription changes (upgrades, downgrades, cancellations) When you make a change to a subscription that has components on different billing frequencies, Frisbii Billing prorates each component based on its own active billing window — not the plan's period. Credits or refunds are calculated per component and applied automatically. --- ## Next steps - Review the [Add-ons](/frisbii/docs/add-ons) article to set up add-on products. - See [Usage-based billing](/frisbii/docs/usage-based-billing) for guidance on usage-based products. - See [Plans](/frisbii/docs/plans) to configure your plan's billing frequency. - See [Subscription Details](/frisbii/docs/subscription-details-edit-pause-expire-cancel) for managing subscriptions. ## Related - [Plans](/plans.md) - [Add-Ons](/add-ons.md) - [Usage-based billing](/usage-based-billing.md) - [Usage-based billing](/metered-billing.md) - [Subscription Details (Edit/Pause/Expire/Cancel)](/subscription-details-edit-pause-expire-cancel.md)
