# Clerk Billing now supports plans with per-seat pricing

Starting today, you can create Plans with per-seat pricing in Clerk Billing, allowing you to charge Organizations based on the number of members using your product.

As your customers get larger, they're getting more value out of your product. A five-person team shouldn't necessarily pay the same amount as a fifty-person team. Per-seat pricing makes it easy to align subscription costs with organization size, allowing pricing to scale naturally as organizations grow.

For example, you might create a Plan with a $12 monthly charge per member. Smaller organizations pay less, while larger organizations are charged proportionally to their team size.

Per-seat pricing is deeply integrated with Clerk Organizations, allowing you to monetize Organization growth without building custom billing or seat management workflows.

## Billing that grows with Organizations

When Organizations add new members, Clerk automatically handles seat provisioning behind the scenes. If an Organization exceeds its available seats when adding members, Clerk guides them through a checkout flow to purchase additional seats, ensuring billing stays aligned with membership. Additional seats purchased during an active billing period are prorated automatically, ensuring organizations only pay for the time those seats are in use.

At the beginning of each billing period, Clerk automatically adjusts the subscription's seat quantity to match the Organization's current membership count. This ensures billing remains aligned with the provisioned members over time and prevents organizations from paying indefinitely for unfilled seats.

Per-seat pricing can be combined with seat limits, allowing you to both charge per member and enforce a maximum Organization size.

Per-seat pricing can also be combined with a fee for the Plan itself, a "base fee", to charge a minimum fee for access to the Plan's features. You can even set an "included" number of seats that come with the base fee; Organizations will only be charged per seat after these included seats are used.

For example, a Plan can have:

- A $20 per month base fee
- An $8 per month per-seat fee
- 2 included seats
- A limit of 10 seats on the Plan

| Organization size | Cost | Breakdown                                                                |
| ----------------- | ---- | ------------------------------------------------------------------------ |
| 1                 | $20  | $20 for the base fee, no seats over the 2 included                       |
| 3                 | $28  | $20 for the base fee, two seats included, $8 for the 1 additional seat   |
| 10                | $84  | $20 for the base fee, two seats included, $64 for the 8 additional seats |

An Organization on this Plan would not be able to invite an eleventh member without changing their Plan, and would be prompted to do so when they go to invite the member.

## A more capable Clerk Billing

When we launched Clerk Billing a year ago, we only supported flat fee pricing for Plans. With the recent launch of seat limits and now per-seat pricing, we hope Clerk Billing can offer a compelling experience for businesses that use a seat-based pricing model.

We're not done with Clerk Billing yet, and are continuously striving to offer more and more powerful tools to let you build the pricing model that will most accurately capture your product's value. We have a lot we're working on, and we can't wait to share it with you.

## Get started with seat-based billing

- Navigate to the [**New Organization plan**](https://dashboard.clerk.com/~/billing/plans/new/org) page in the Clerk Dashboard.
- Toggle on the **Seat-based** section.
- If you'd like to set a limit, select **Custom limit** and enter the desired value. (You need the B2B Authentication add-on to set a limit greater than 20.)
- If you'd like the Plan to allow an unlimited number of seats, select **Unlimited members**. (You need to have the B2B Authentication add-on to select this option.)
- Toggle on the **Per-seat fee** section.
- Enter the price per seat in the **Cost per member seat monthly** section.
- If you'd like to include free seats in the plan, enter the desired value in the **Included seats** section.
