# Tell subscribers before a price rise

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Required
- Chapter: [Subscriptions](https://agentwranglers.se/playbook/payments/subscriptions)
- Rule: Email every affected subscriber at least 30 days before a higher price applies. Give the old and new price, the date and a cancel link.
- How: A price rise changes the contract the customer agreed to. California's automatic renewal law requires clear notice of a material change before it applies, and EU contract terms usually need advance notice too. Create the new price in the [versioned catalogue](https://agentwranglers.se/playbook/payments/checkout-and-card-data/price-catalogue). Store one notice row per subscription with the time it was sent. Move a subscription to the new price only when its notice is at least 30 days old. Anyone who cancels before that date keeps the old price until the end.
- Check: A test runs the price move with one subscriber notified 31 days ago and one notified 5 days ago. Only the first moves. The job refuses any subscription without a notice row.

Example:

```js
const NOTICE_DAYS = 30
const DAY_MS = 24 * 60 * 60 * 1000

function mayMoveToNewPrice(notice, now = new Date()) {
  return Boolean(notice) && now.getTime() - notice.sentAt.getTime() >= NOTICE_DAYS * DAY_MS
}
```

```python
from datetime import datetime, timedelta, timezone

NOTICE = timedelta(days=30)

def may_move_to_new_price(notice, now: datetime | None = None) -> bool:
    now = now or datetime.now(timezone.utc)
    return notice is not None and now - notice.sent_at >= NOTICE
```
