Stripe returns subscription_update_trial_after_billing_cycle_anchor when the billing_cycle_anchor you provide is before the subscription’s trial_end. The anchor has to come after the trial ends, or the trial has to end first.

**Short answer**
Compare the billing_cycle_anchor you send with the subscription’s trial_end. The simplest fix is to end the trial in the same update with trial_end set to now. Stripe’s docs describe resetting the anchor to a specific time only for subscriptions on flexible billing mode. This applies to subscriptions that use the trial_end parameter, which Stripe now labels legacy; trial offers handle the anchor differently.
Rather not fix it yourself? [**Stripe Billing Fix and Setup**](https://app369.com/fixed-price/stripe-billing-setup/) handles it at a fixed price, agreed before work starts.
## **Why the anchor is rejected, and the fix**
1. 01 ### **The anchor falls inside the trial**
> “Update the billing cycle anchor to be after the trial’s end date or end the trial with trial_end="now".” [**Stripe, Error codes (subscription_update_trial_after_billing_cycle_anchor)**](https://docs.stripe.com/error-codes) Stripe requires a new billing cycle anchor to be after the subscription’s trial end. Pick an anchor after trial_end where your billing mode supports it, or end the trial first.
2. 02 ### **The trial should end now**
> “To end a trial early, make an update subscription API call, setting the trial_end value to a new timestamp, or now to end immediately” [**Stripe, Free trials**](https://docs.stripe.com/billing/subscriptions/trials/free-trials) If the customer is converting early, end the trial in the update. Setting trial_end to now ends it immediately.```
await stripe.subscriptions.update(subscriptionId, {
trial_end: 'now',
});
```
3. 03 ### **You want a trial and a fixed billing day**
> “You can combine trials with billing_cycle_anchor, resulting in a free period followed by a prorated period, leading into a fixed billing period.” [**Stripe, Free trials**](https://docs.stripe.com/billing/subscriptions/trials/free-trials) Stripe’s example sends trial_end and billing_cycle_anchor together when the subscription is created, with trial_end earlier than the anchor. On an existing subscription, setting trial_end moves the anchor to that same date. In the docs’ example the customer gets the free period, then, depending on the trial length, a prorated invoice up to the anchor, then full invoices.

Questions
## **More on this error**
**What does the billing cycle anchor do? **+
It is the reference point that aligns future billing period dates, such as the day of the month a monthly subscription renews.
**Does Checkout support a trial with a billing cycle anchor? **+
No. Stripe’s billing cycle docs say Checkout doesn’t support combining a trial with the billing cycle anchor, and Stripe says that combination is available through the API.
**Can you fix it for me? **+
If one bug is the whole problem, the App Fix Ticket covers it: a written diagnosis first, then the fix. If the app has more going on, the Launch Check is a written check of the whole app. Each issue found is rated critical, high, medium or low, with where it is and how it was confirmed. No issues worth fixing, no charge. If the Launch Check finds nothing rated medium or higher, Simon refunds the full $450. You keep the report either way.
