# Buy or Upgrade a Plan

## Buying

1. Open the **Plans** tab in the add-in and pick a plan and billing period (monthly or yearly — yearly saves 40%).
2. **Sign in** if you haven't — a purchase must be attached to an account. Twistly asks automatically and continues to checkout afterwards.
3. Complete payment in the secure checkout (processed by Paddle, our payment provider). Prices are shown in your local currency where supported.

A receipt is emailed to you by Paddle after every charge.

**Your plan can take a moment to activate.** Payment confirmation travels from the payment provider to Twistly, which usually takes seconds but occasionally longer. If your plan hasn't updated a couple of minutes after paying, close and reopen the add-in. Still not active? [Contact us](/help/contact-us.md) with the email you used at checkout — we'll sort it out.
{% endhint %}

## Upgrading

Upgrade anytime from the Plans tab (for example Starter → Pro). You'll see a confirmation first, and the price difference is **prorated** — you only pay for the remainder of the current billing period at the new rate.

* On a Team plan, **only the team owner** can change the plan or buy seats.
* **Downgrading** to a cheaper plan isn't available in the add-in — [contact us](/help/contact-us.md) and we'll help.

## Managing billing

Cancel or pause anytime — see [Cancel or Pause a Subscription](/plans-billing-and-team/cancel-or-pause.md). You can also manage your subscription without the add-in at [twistly.ai/manage-subscription](https://twistly.ai/manage-subscription/).
