# action.upgrade

Starts or manages paying for more: upgrade, change plan, manage billing

Component: [`<Action>`](https://www.prongs.dev/docs/components/action.md) · Renders: `<button>` · Profile: [UI](https://www.prongs.dev/docs/intents/ui.md) · Comes from: [SaaS pack](https://www.prongs.dev/docs/intents/packs/saas.md)

## Example

```tsx
<Action intent="action.upgrade" href="/billing">Upgrade to Pro</Action>
```

Code that says `upgrade`, `plan`, `billing`, `pro` points here. `prongs check` warns when an element with this intent has a handler or label that points somewhere else.

## Choosing between neighbours

Find the row that describes your element, and use the intent on the right.

| If it is for… | Use |
|---|---|
| Starts or manages paying for more: upgrade, change plan, manage billing | `action.upgrade` (this page) |
| Beginning something new, like a project or a trial | [`action.start`](https://www.prongs.dev/docs/intents/action/start.md) |

## Connections

Declared in the registry, both directions. Where an intent is used in your own code is something check and the gallery see; this site has no app code.

- Built from: [`control.primary`](https://www.prongs.dev/docs/intents/ui.md#control-primary)

## For registry authors

**Pack intent.** `prongs add saas` puts the saas pack’s intents in your registry. They are then yours like the starter intents: rename, restyle and add to them, and see them with `prongs add gallery`.

What this intent is built from and its entry in `components/prongs/registry.ts`. You only need this to change how it looks or to add an intent like it.

How action.upgrade resolves, and its definition

Each layer adds to the one before it; a later class wins over an earlier one that sets the same thing.
