# Plans and billing

> Compare Helix Foundry Free, Pro and Max, upgrade a workspace, switch tiers, cancel, resume and manage payment

Guide

Each workspace has one Foundry plan, billed monthly and separately from Helix Cloud.
Owners and admins change it in **Settings** → **Plan & billing**; members see which plan
the workspace holds.

| | Free | Pro | Max |
| - | - | - | - |
| Price | \$0 | \$100 a month | \$500 a month |
| Stripe, WorkOS and PostHog | ✓ | ✓ | ✓ |
| Syncs and synced tables | ✓ | ✓ | ✓ |
| Ontology generation and versions | ✓ | ✓ | ✓ |
| PostgreSQL and MySQL | | ✓ | ✓ |

Max includes everything in Pro, and will add more.

On Free, choosing PostgreSQL or MySQL in **Add data** says the source needs Pro, and
offers owners and admins **Upgrade to Pro**.

## Upgrade

**1. Choose a tier**

Select **Upgrade**, choose **Pro** or **Max**, and add a promotion code if you have
one.

**2. Pay**

Select **Continue to payment**. Foundry opens Stripe Checkout, or charges the card on
file when the workspace has one.

**3. Come back**

Stripe returns you to **Plan & billing**, which checks the payment until the new plan
shows. PostgreSQL and MySQL are available at once.

If an upgrade's answer is lost, for example when the network drops, the page checks the
plan before it offers checkout again, so you aren't charged twice.

## Switch between Pro and Max

On a paid workspace, select **Switch to Max** or **Switch to Pro** on the other tier's
card and confirm.

## Cancel or resume

Select **Cancel Pro** (or **Cancel Max**) and confirm. The plan stays on until the end
of the period, then the workspace moves to Free and its PostgreSQL and MySQL connections
stop syncing. Until then, **Resume Pro** (or **Resume Max**) undoes the cancellation.

## Manage payment and invoices

Select **Manage billing** to open the Stripe billing portal for the workspace: payment
methods, invoices and billing details. When an invoice isn't paid, the page says so and
offers **Update payment method**; cancelling and switching wait until it's paid.
