# Plans and limits

> What the Hobby and Professional plans include, and what happens at the edges.

Harness has two plans. **Hobby** is free and runs a small studio end to end; **Professional** removes the student limit and adds the automation. Pricing lives on the Harness website; changing plans is covered in [Manage your plan](/settings/manage-your-plan).

## What's on which plan

Everything core is free: the calendar, students (up to 5), attendance-driven charges, manual invoicing and payments, expenses, mileage, and reports.

The Professional plan adds:

| Feature                 | What it unlocks                                                                                           |
| ----------------------- | --------------------------------------------------------------------------------------------------------- |
| **Unlimited students**  | The Hobby plan caps at 5 active students.                                                                 |
| **Online payments**     | [Connect Stripe](/billing/connect-stripe) so invoices carry a pay link.                                   |
| **Booking links**       | [Scheduling links](/calendar/scheduling-links) and [reschedule links](/calendar/reschedule-links).        |
| **Automatic invoicing** | Per-lesson drafts or the monthly batch; see [Run your monthly billing](/guides/run-your-monthly-billing). |
| **Invoice reminders**   | Automatic and manual nudges on unpaid invoices; see [Invoice reminders](/billing/invoice-reminders).      |

On the Hobby plan, a locked feature shows a lock icon; the rest of the app is unaffected.

## The trial

New studios start on a Professional trial, no card required. The card at the bottom of the sidebar counts down the days and links to your plan. When the trial ends you choose: upgrade, or continue on Hobby and keep everything you've built (as long as you're within the student cap).

## The 5-student cap

The **Students** page shows a usage meter ("3 / 5 students") as you approach the cap. At the limit, the **Add student** button is disabled and sign-up approvals are blocked until you free a slot or upgrade. Only **active** students count.

## Over the cap when the trial ends

If your trial ends with more than 5 active students, Harness asks you to choose before you continue: **upgrade to keep everyone**, or **pick the 5 students to stay active**. The students you don't pick become **locked**, and nothing is deleted: their history, records, and balances all stay.

## Locked students

A locked student sits in the **Inactive** tab with a lock badge. While locked, they can only be **edited** or **deleted**; there's no activate or deactivate. Upgrading unlocks everyone at once. Deleting a locked student [frees a slot](/students/delete-a-student).
