# Upgrading and downgrading

> Changing plan or billing period, and what happens to what you have already paid.

Every plan change happens on your
[billing page](https://myclerkbook.com/app/settings/billing). There is one
place to do it, and every `Upgrade` prompt in the app leads there.

## Changing plan

<Steps>
  <Step title="Open billing">
    Account menu → **Billing**, or go straight to
    [/app/settings/billing](https://myclerkbook.com/app/settings/billing).
  </Step>

  <Step title="Pick monthly or yearly">
    The toggle above the plans changes which price you are choosing.
  </Step>

  <Step title="Choose the plan">
    A summary appears first, showing the plan, the full price and the renewal
    cadence.
  </Step>

  <Step title="Review, then confirm">
    Payment fields open only after you have seen that summary and chosen to
    continue. You can leave at that point without being charged.
  </Step>
</Steps>

<Note>
  The review step is deliberate. You are shown exactly what is being bought and
  at what total price before any payment details are asked for, and the exit is
  available at every stage until payment is confirmed.
</Note>

## Monthly to yearly, and back

Switching between monthly and yearly is a change of product rather than a
setting, because the billing interval is fixed on the product itself. In
practice that means you choose the yearly price the same way you chose the
monthly one, from the same plan card, with the toggle set to yearly.

## When the change takes effect

<CardGroup cols={2}>
  <Card title="Upgrades" icon="arrow-up">
    Immediate. The new limits apply as soon as the payment is processed and
    your account is updated.
  </Card>

  <Card title="Downgrades and cancellations" icon="arrow-down">
    At the end of the period you have already paid for. You keep what you paid
    for until then.
  </Card>
</CardGroup>

A cancelled subscription reads **Cancelling at the end of the period** on your
billing page until that date arrives, then reads as ended. Cancelling is never
the same thing as losing access on the spot.

## The Agent add-on

The Agent is added and removed independently of your plan. Adding it does not
change your plan, and changing your plan does not remove it.

## If a payment fails

Your billing page always states the plan you currently hold. A failed payment
never leaves that ambiguous. If a charge does not go through, the page says
what plan you are on and what happened, rather than showing a plan you may not
have.
