Set different billing frequencies for add-ons and usage-based billing products

Plans supporting this feature: Starter Growth Scale

Overview

By default, all components of a subscription — the base plan, add-ons, and usage-based billing products — share the same billing frequency. 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.

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).

• You have created or are creating an add-on or usage-based billing product (see Add-ons and Usage-based billing).

• Understand the compatibility rules below before configuring frequencies.

Compatibility rules

Not all combinations of plan and component frequencies are valid. Frisbii Billing enforces the following rules:

🚫 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:

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.

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.

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.

🚫 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.
