# Plans and billing

Plans control product capabilities. When billing is enabled, payment uses Stripe **hosted checkout** — Quanorix does **not** store card data.

<Note>
  If Profile says payments are not enabled (`STRIPE_BILLING_ENABLED`), this environment is not taking charges; the rest of the app may still work.

## Plans (summary)

| Plan       | Price (landing) | Focus                                                                       |
| ---------- | --------------- | --------------------------------------------------------------------------- |
| **Free**   | \$0/mo          | Explore: basic generation, personal databank, limited export                |
| **Pro**    | \$29/mo         | Mass generation, walk-forward/robustness, portfolios, full MQL export, jobs |
| **ProMax** | \$79/mo         | Everything in Pro + regime, mixer, priority, priority support               |

Exact feature blurbs may evolve on the landing/Profile; treat the UI as the source of what **your** account can do today.

## Where to manage it

Under **Profile → subscription / plan**:

* Current plan
* **Switch to this plan** (upgrade/downgrade)
* **Manage billing** → Customer Portal (payment method, cancellation via Stripe)
* **Billing history** (invoices, PDF, pay/retry if open)
* **Access code** (promo redeem)

## Upgrade and downgrade

| Change                                        | Plan effect                                                                       |
| --------------------------------------------- | --------------------------------------------------------------------------------- |
| Free → Pro / ProMax                           | Hosted checkout; after successful charge the plan rises **immediately** (webhook) |
| Pro → ProMax (or other paid upgrade)          | Subscription update with proration; higher plan **immediate**                     |
| Downgrade (e.g. ProMax → Pro, or paid → Free) | **Scheduled for period end**; you keep the current plan until then                |

The UI shows copy like *Change scheduled for end of billing period* or *Subscription updated*.

## Portal and invoices

* **Manage billing** opens the processor portal (no PCI in Quanorix).
* **History** shows Paid / Open / Void / etc., plus **PDF** when available.
* Failed recurring charges: use **Pay / retry** or the portal.

## Promo access code (redeem)

If you have a code:

1. Profile → **Access code** → enter code → **Redeem**.
2. Activates Pro or ProMax for a **limited time** (`until <date>`).
3. Typical errors: invalid, expired, no uses left, already redeemed, or **you already have an active paid subscription** (promo will not overwrite it).

We do not document admin code creation — only customer redeem.

## Common issues

* Checkout cancelled → plan unchanged; try again.
* Plan not reflecting payment instantly → wait a few seconds and reload.
* Portal won’t open → session / billing disabled in the environment.
