Subscription schedules

Learn about subscription schedules and how to use them.

Use subscription schedules to automate changes to subscriptions over time. You can create subscriptions directly through a schedule or you can add a schedule to an existing subscription. Use the phases attribute to define the changes you want to make to the subscription. After a schedule completes all of its phases, it completes based on its end_behavior.

Some changes you might want to schedule include:

  • Starting a subscription on a future date
  • Backdating a subscription to a past date
  • Upgrading or downgrading a subscription

Subscription schedules are available in both the Stripe Billing Dashboard and the API. Here’s a quick video of how subscription schedules work in the Dashboard:

Subscription schedules in the Dashboard

The rest of this document explains subscription schedules in more detail. To see a list of examples, see the use cases page.

Phases

When creating a subscription schedule, use the phases attribute to define when changes occur and what properties of the subscription to change. For example, you might offer a coupon for 50% off for the first three months of a subscription. In this scenario, you’d create a subscription schedule where the first phase is three months long and contains the 50% off coupon. In the second phase, the subscription would be reverted to the normal cost and the coupon would be removed. Phases must be sequential, meaning only one phase can be active at a given time. You can have up to 10 phases.

Set the length of a phase

The interval of a price determines how often to bill for a subscription. For example, a monthly interval is billed every month. Phases have an iterations attribute that you use to specify how long a phase should last. Multiply this value by the interval to determine the length of the phase. If a subscription schedule uses a price with a monthly interval and you set iterations=2, the phase lasts for two months.

The end_date of one phase has to be the start_date for the next phase. Using iterations automatically sets the start_date and end_date properly. You can set these values manually, but Stripe recommends using iterations instead. Because manually setting the start and end dates is prone to errors, only use it for advanced use cases.

Transition to the next phase

Phase transitions happen automatically after the end_date on a phase is reached. When a phase starts, Stripe updates the subscription based on the attributes of the next phase. You can optionally enable proration to credit the user for unused items or time on the plan.

Use trials

You can add trial periods by setting trial end on a phase. If you want the entire phase to be a trial, set the value of trial_end to the same time as the end_date of the phase. You can also set trial_end to a time before the end_date if you want to make only part of the phase a trial. When scheduling updates, you must specify the new trial_end on each phase.

Complete a schedule

Subscription schedules end after the last phase is complete. At this point, the subscription is left in place and is no longer associated with the schedule. If you want to cancel a subscription after the last phase of a schedule completes, you can set end_behavior to cancel.

Phase attribute inheritance

When a phase becomes active, all attributes set on the phase are also set on the subscription. After the phase ends, attributes remain the same unless the next phase modifies them, or if the schedule has no default setting. You can set some attributes on both schedules and phases. This includes:

Schedule attributePhase attribute
default_settings.billing_thresholdsphases.billing_thresholds
default_settings.collection_methodphases.collection_method
default_settings.default_payment_methodphases.default_payment_method
default_settings.invoice_settingsphases.invoice_settings

If one of these attributes is defined on the schedule, it becomes the default for all phases. When the same property is defined on both the schedule and the phase, the phase attribute overrides the schedule attribute. This behavior is explained more below:

Schedule attribute presentPhase attribute presentOutcome
NoNoDefaults to the customer or account settings
YesNoSchedule attribute set
YesYesPhase attribute set
NoYesPhase attribute set

Use phase metadata

You can use subscription schedule phases to set metadata on the underlying subscription. This allows you to control the metadata on a subscription with scheduled updates.

To use phase metadata with the API, set metadata on the phases of a subscription schedule. When the underlying subscription enters a phase:

  • Metadata from the phase with non-empty values are added to the metadata on the subscription if the keys aren’t already present in the latter.
  • Metadata from the phase with non-empty values are used to update the metadata on the subscription if the keys are already present in the latter.
  • Metadata from the phase with empty values are used to unset the corresponding keys in the metadata on the subscription.

To unset all keys in the subscription’s metadata, update the subscription directly or unset every key individually from the phase’s metadata. Updating the underlying subscription’s metadata directly doesn’t affect the current phase’s metadata.

The following example illustrates a subscription schedule with two phases, where each phase has its own metadata:

{
  ...
  "object": "subscription_schedule",
  "phases": [
    { // Phase 1
      ...
      "metadata": {
        "channel": "self-serve",
        "region": "apac",
        "upsell-products": "alpha"
      },
    },
    { // Phase 2
      ...
      "metadata": {
        "channel": "sales",
        "churn-risk": "high",
        "upsell-products": ""
      },
    }
  ],
}

When this schedule creates a new subscription and the subscription enters Phase 1, the three keys in Phase 1 metadata are added to the subscription’s metadata. Hence, the subscription in Phase 1 has the following metadata:

{
  ...
  "object": "subscription",
  "metadata": {
    "channel": "self-serve",
    "region": "apac",
    "upsell-products": "alpha"
  },
}

When the subscription enters Phase 2, the subscription’s metadata is updated:

  • The value of channel is updated because a value is specified on the phase’s metadata and the subscription already has metadata with that key.
  • The value of region is unchanged because it’s not specified on the phase.
  • churn-risk is added because this is a new key.
  • upsell-products is unset because an empty value is specified on the phase.

Hence, the subscription in Phase 2 has the following metadata:

{
  ...
  "object": "subscription",
  "metadata": {
    "channel": "sales",
    "region": "apac",
    "churn-risk": "high"
  }
}

Learn how to copy subscription metadata onto subscription invoices.

Create subscription schedules

The use cases page has more thorough examples but below is a basic example of creating a subscription schedule using a customer. Creating a schedule this way automatically creates the subscription as well.

Note

Unlike when you create a subscription directly, the first invoice of a subscription schedule with collection_method set to charge_automatically behaves like a recurring invoice and isn’t immediately finalized at the time the schedule’s subscription is created. The invoice begins in a draft status and is finalized by Stripe about 1 hour after creation.

This means that, for example, creating a charge-automatically subscription schedule with start_date=now also creates a subscription and an invoice in the draft status. This gives you a 1-hour window to make edits to the invoice. Later, the invoice is auto-advanced into the open or paid status depending on the outcome of the asynchronous payment attempt at finalization time.

Command Line
curl https://api.stripe.com/v1/subscription_schedules \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d customer=cus_GBHHxuvBvO26Ea \
  -d start_date=now \
  -d end_behavior=release \
  -d "phases[0][items][0][price]"=price_1GqNdGAJVYItwOKqEHb \
  -d "phases[0][items][0][quantity]"=1 \
  -d "phases[0][iterations]"=12

This schedule:

  • Starts as soon as it’s created.
  • Sets the subscription to one instance of the product at price_1GqNdGAJVYItwOKqEHb.
  • Goes through 12 iterations and then releases the subscription from the schedule.

You can also create subscription schedules by passing a subscription ID:

Command Line
curl https://api.stripe.com/v1/subscription_schedules \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d from_subscription=sub_GB98WOvaRAWPl6

Creating a schedule this way uses attributes on the subscription to set attributes on the schedule.

Similar to other Stripe APIs, you can retrieve and update subscription schedules. You can also cancel and release them. Cancelling a subscription schedule cancels the subscription as well. If you only want to remove a schedule from a subscription, use the release call.

Update subscription schedules

You can only update the current and future phases on subscription schedules.

You need to pass in all current and future phases when you update a subscription schedule. You also need to pass in any previously set parameters that you want to keep. Any parameters that were previously set are unset for the existing phase unless you pass those in the update request. You still receive information in the response about past phases.

You can include up to 10 current or future phases. Updating the active phase updates the underlying subscription as well. For example, this call maintains the existing start and end dates, but updates the quantity to two:

Command Line
curl https://api.stripe.com/v1/subscription_schedules/
{{SUBSCRIPTION_SCHEDULE_ID}}
 \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "phases[0][items][0][price]"=
{{PRICE_ID}}
 \
  -d "phases[0][items][0][quantity]"=2 \
  -d "phases[0][start_date]"=1577865600 \
  -d "phases[0][end_date]"=1580544000

You can also end the current phase immediately and start a new phase. This moves the active phase to the past and immediately applies the new phase to the subscription. The example below ends the current phase and starts a new phase:

Command Line
curl https://api.stripe.com/v1/subscription_schedules/
{{SUBSCRIPTION_SCHEDULE_ID}}
 \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "phases[0][items][0][price]"=
{{PRICE_ID}}
 \
  -d "phases[0][items][0][quantity]"=1 \
  -d "phases[0][start_date]"=1577865600 \
  -d "phases[0][end_date]"=now \
  -d "phases[1][items][0][price]"=
{{PRICE_ID}}
 \
  -d "phases[1][items][0][quantity]"=2 \
  -d "phases[1][start_date]"=now \
  -d "phases[1][end_date]"=1580544000

To add additional phases to a subscription schedule, pass in the current phase, and then define your new phases:

Command Line
curl https://api.stripe.com/v1/subscription_schedules/
{{SUBSCRIPTION_SCHEDULE_ID}}
 \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "phases[0][items][0][price]"=
{{PRICE_ID}}
 \
  -d "phases[0][items][0][quantity]"=1 \
  -d "phases[0][start_date]"=1577865600 \
  -d "phases[0][end_date]"=1580544000 \
  -d "phases[1][items][0][price]"=
{{PRICE_ID}}
 \
  -d "phases[1][items][0][quantity]"=2 \
  -d "phases[1][iterations]"=1

Preview an invoice

Use the schedule parameter in the create preview to preview the next invoice for a subscription schedule.

Command Line
curl https://api.stripe.com/v1/invoices/create_preview \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d schedule=
{{SUBSCRIPTION_SCHEDULE_ID}}

Previewing schedule creation and updates

Use the parameters in schedule_details to preview creating or updating a subscription schedule. Pass an existing schedule to tell Stripe whether it’s a creation or an update.

Pass all of the current and future phases you’re previewing.

For example, the following code previews the first invoice for a subscription schedule with 1 phase that lasts for 12 billing periods.

Command Line
curl https://api.stripe.com/v1/invoices/create_preview \
  -u "
sk_test_4eC39HqLyjWDarjtT1zdp7dc
:" \
  -d "customer_details[address][line1]"="920 5th Ave" \
  -d "customer_details[address][city]"=Seattle \
  -d "customer_details[address][state]"=WA \
  -d "customer_details[address][postal_code]"=98104 \
  -d "customer_details[address][country]"=US \
  -d "schedule_details[phases][0][start_date]"=now \
  -d "schedule_details[phases][0][items][0][price]"=
{{PRICE_ID}}
 \
  -d "schedule_details[phases][0][items][0][quantity]"=1 \
  -d "schedule_details[phases][0][iterations]"=12

Additional considerations

Subscription schedules generally follow the same restrictions as subscriptions, but also introduce some of their own restrictions. Additionally, the interaction between subscription schedules and subscriptions can produce unexpected behavior. Review the following sections to understand limitations, product behavior, and general best practices when using subscription schedules.

Restrictions

  • You can only define up to 10 current or future phases at a time on a subscription schedule. Past phases don’t count against this limit.
  • Subscription schedule phases also follow the same restrictions as subscriptions when creating subscription schedule phases with multiple items.

Dashboard limitations

You can create and update subscription schedules without code in the Dashboard.

In the Dashboard, you can set the following settings globally across all phases, but not on a per phase basis:

  • Billing thresholds
  • Payment methods
  • Invoice settings
  • Subscription description
  • Trial days (only works with the first phase)

The following parameters aren’t supported in the Dashboard:

  • Subscription schedule metadata
  • Phase item metadata
  • Currency
  • All Connect parameters

Subscription updates when a schedule is attached

Use subscription schedules to modify subscriptions automatically when time passes and the schedule’s next phase is entered. Some changes that you make directly to the subscription propagate to the subscription schedule’s phases, but some don’t. This means that any modifications you make directly to the subscription might be overwritten by the subscription schedule when the next phase is entered.

When scheduling changes to a subscription, follow these best practices:

  • If a subscription has a subscription schedule attached, use the Subscription Schedule API to modify the subscription, instead of the Subscriptions API.
  • Store the subscription schedule IDs alongside the subscription ID for future API updates. The subscription schedule ID returns when you use the API to create it or through the subscription_schedule.created webhook when Stripe creates it automatically, such as when a customer scheduled a downgrade in the Customer Portal.
  • Discard the subscription schedule IDs when a subscription schedule is released. You can make changes to the subscriptions directly or create a new subscription schedule. The subscription schedule ID is returned when released with the API or through the subscription_schedule.released webhook event when the subscription schedule releases.
  • Use the Dashboard to modify subscriptions, if possible, which automatically updates any attached subscription schedule.

Specifically, when you change any of the following subscription attributes directly on a subscription, this action might automatically create a new subscription schedule phase:

  • discounts
  • tax_rates
  • items
  • trial_end, trial_settings, trial_start
  • application_fee_percent
  • add_invoice_items
  • automatic_tax

For example, consider a subscription with two items. The subscription has a subscription schedule attached with a single phase, mirroring the current state of the subscription. If you use the API to delete one of the items, this automatically splits the attached subscription schedule’s phase into two phases:

  1. The phase that just ended and had two subscription items
  2. The new phase that has just one item on the subscription

When subscription schedule phases automatically split, the following properties are copied from the current phase to the new phase:

  • proration_behavior
  • billing_cycle_anchor
  • cancel_at_period_end
  • description
  • metadata
  • pause_collection

Additionally, Stripe might copy the following top-level subscription attributes to the subscription schedule or its default_settings:

Subscription attributeCopied to new subscription schedule phaseCopied to subscription schedule default_settings
couponX
trial_endX
tax_ratesX
application_fee_percentXX
discountsX

invoice_settingsXX
default_payment_methodXX
default_sourceXX
transfer_dataXX
on_behalf_ofXX
billing_thresholdsXX
currencyX
add_invoice_itemsX
automatic_taxXX
items.pricesX

Updates to subscription metadata aren’t propagated to an attached subscription schedule.
