Migrate subscriptions to Stripe Billing using toolkit

Learn how to migrate your existing subscriptions to Stripe using the toolkit.

Use the Billing migration toolkit in the Stripe Dashboard to migrate your existing subscriptions from a third-party system, a home-grown system, or an existing Stripe account to Stripe Billing.

Before you begin

If you haven’t already, review the migration stages .
Set up a Stripe Billing integration before you begin migration. This is a one-off setup that you don’t need to repeat for future migrations.
Request a payments data import from your current processor. This step is only required if you’re migrating to Stripe from another processor. If you’re migrating from Stripe to Stripe, you can skip this prerequisite.
Make sure customers that you want to charge automatically have a default payment source (a payment method ), or add a default . Without a default payment source, subscription invoices can’t collect payment. For more details, see the CSV prerequisites .
If you’re migrating from a third-party or home-grown system:

First, create new subscriptions in Stripe.
After creating new subscriptions, cancel old subscriptions before they charge so you don’t double-bill.
If a subscription’s billing date is close to migration, schedule the new Stripe subscription to start after the last charge from the old subscription to make sure the migration has time to complete. Then cancel the old subscription.

Open the Billing migration toolkit

Create a sandbox in the Dashboard if you want to run a test migration first.

Go to Dashboard > Subscriptions > Migrations. Alternatively, you can click the overflow menu () next to + Create subscription, and select Migrate subscriptions.
To start your migration, click Let’s get started.

Download a CSV file

First, export your existing subscriptions by matching the exported data to a migration-compatible CSV file. You can create your own CSV file, or download any of the following CSV templates provided by Stripe ( Basic, Multi-price items, and Ad-hoc pricing). You can also find examples of CSV files for common migration use cases.

Click Download CSV template.
Choose a CSV template (basic, multi-price items, or ad-hoc pricing) based on your billing use case. Basic CSV This example shows a migration for common subscription use cases such as quantity, taxes, billing anchor, discounts, trials, and backdating. Specify the following fields for a Basic CSV file: Download basic CSV template Multi-price items CSV This example shows a migration that has multiple products per subscription. Specify the following fields for a Multi-price items CSV file: Download multi-price CSV template Ad-hoc prices CSV This example shows handling a subscription migration using ad-hoc pricing for existing products. Specify the following fields for an Ad-hoc pricing CSV file: Download ad-hoc pricing CSV template
In the CSV file, specify the details of the subscriptions you want to export. For Stripe-to-Stripe migrations If you’re migrating subscriptions within Stripe accounts, refer to the CSV example before you specify and upload a CSV file.

Upload a CSV file

Click Upload CSV. The CSV file size limit is 120 MB.

Stripe validates the file to verify that the uploaded subscriptions are in the required CSV format. This process might take up to a few hours, depending on the size of the file. If the file is valid, you can proceed to the next step in the migration. If there are any validation errors, you must resolve the errors to proceed.

Validate default payment sources

Before uploading, use Advanced settings to configure default payment source validation. By default, Allow subscriptions without a default payment source is unchecked, which means Stripe blocks any charge_automatically subscription in your CSV where the customer doesn’t have a default payment source on file.

This check only applies to charge_automatically subscriptions. Subscriptions using send_invoice don’t require a default payment source because Stripe emails the customer an invoice that they pay directly.

Risk of disabling this check

If you check Allow subscriptions without a default payment source, subscriptions without a default payment source still get imported successfully, but their invoices fail to collect at billing time. If you disable this validation, make sure every affected customer has a default payment source attached before their first billing date.

If validation fails due to missing payment sources, see Add a missing default payment source.

Review uploaded subscriptions

After Stripe validates your CSV file, review the summary of your uploaded subscriptions for any discrepancies:

Cross-check the summary for the correct:

Date of upload
Uploaded file name
Number of subscriptions
Number of customers
First subscription go-live date

If everything is valid, click Start migration. If you see errors, click Cancel migration and restart the migration from Download a CSV file.

Track migration progress

After you review your uploaded subscriptions, track the progress of your migration:

Migration progress	Description
Migration in progress	Your subscriptions are queued to schedule on the specified start date. This process can take a few minutes to a few hours, depending on the size of the file. For example, the validation and migration for 100,000 subscriptions takes approximately 30 minutes to complete. The Billing migration toolkit uses the Subscription schedule to migrate your subscriptions. This allows your subscriptions to remain in a scheduled state for 24 hours before going live. In a sandbox, the buffer time is reduced to 1 hour for faster evaluation and testing.
Scheduled subscriptions	After migration, your subscriptions remain in a scheduled state for 24 hours before going live. You have 10 hours to cancel these scheduled subscriptions using the toolkit. You can’t update scheduled subscriptions using the migration toolkit. If you want to update your scheduled subscriptions, you can either call the update endpoint, or update each subscription individually in the Subscriptions page of the Dashboard. Customers can’t cancel scheduled subscriptions from their customer portal. They can only cancel live subscriptions.
Go live with subscriptions	After 24 hours, your scheduled subscriptions go live and charge customers on their applicable start dates. You can view all your live subscriptions in the Subscriptions page of the Dashboard. After the migration goes live, we recommend you monitor your subscriptions starting from the first payment. Make sure the charge dates and amounts for the migrated subscriptions match the specified start_date. Customers can cancel live subscriptions from their customer portal.
Monitor subscriptions	After the migration goes live, monitor your subscriptions for problems related to payment methods. For example, check transactions for unrecoverable issuer decline codes such as `incorrect_number` and take action to make sure invoices get paid. Consider notifying customers that have invalid payment methods through channels other than email, such as text messages or in-app notifications. When using automatic collection, check open or overdue invoices to make sure customers aren’t missing default payment methods, which might cause the invoice to be unable to attempt collection.

View all migrations

To view all of your migrations:

Select the migration you want to review in Migrations.
To open a migration, click View in the dropdown menu. You can track the following fields:

Upload date
File name
Stripe billing migration id
Number of subscriptions
Migration status

Optional Cancel a migration

If you identify any problems with the scheduled subscriptions, you can roll back the migration and revert the scheduled subscriptions. The Dashboard displays a timestamp to indicate if you can still cancel the migration using the toolkit. You have 10 hours from when you scheduled the subscriptions to cancel them. After 10 hours, the cancel option is disabled in the toolkit. To cancel the migration after 10 hours, you can either call the cancel endpoint, or individually cancel each subscription in the Subscriptions page of the Dashboard.

Find the migration you want to cancel in your Migrations .
Click Cancel migration in the dropdown menu.

Optional Run multiple migrations

You can run as many simultaneous subscription migrations as you want. For large migrations, divide the subscriptions into batches and start with a small batch. This can help you quickly identify any validation issues and save validation time.

To start a new migration:

Click Start new migration .
Restart the migration process from Download a CSV file .

You can also find examples of CSV files for common migration use cases.

Optional Resolve validation errors

Optional Add a missing default payment source

Migration use cases

You can apply the migration use cases in this section to your own migration, if applicable. Timestamps in these examples are in Unix the related setting format. The examples also include test customer and price IDs that you can use in a sandbox.

You can combine any Stripe-provided CSV template ( Basic, Multi-price items, Ad-hoc pricing) with any of these examples as needed.

Migrate subscriptions with various pricing models

Migrate subscriptions with different types of payment collection methods

Migrate subscriptions at different stages of subscription service period

Migrate subscriptions with taxes

Migrate subscriptions with discounts

Migrate subscriptions with multiple phases

CSV reference

The migration toolkit requires you to upload a CSV that has specific information in the correct fields.

CSV prerequisites

Before you create or download a CSV file, make sure you have access to the following information:

Customer object	All customers must have a default payment method attached to them. Without a default payment method, future subscription payments will fail. If you don’t have a default payment method set for your customers after migrating their data, you have two options: Obtain the user’s consent or rely on their past payment behaviour to determine the default payment method on a per-customer basis. Use this provided script to attach the latest payment method to your customers and make it the default method.
Automatic tax	If you use Stripe Tax (where you set automatic tax to true), all customers must have either addresses or postal codes (or both) per country. Stripe needs this information to calculate taxes for the given subscriptions.
collection_method	If you’re using the `send_invoice` payment method for your subscriptions: Add email addresses to the required customers. Add the days_until_due parameter in the migration CSV file to state the validity of invoices for each customer.
Dates	To ensure accurate timing, pay special attention to time zones when you create epoch date-time formats for your migration CSV file. For the toolkit, set the start_date with a buffer of at least 24 hours in advance from the CSV upload time. We create a subscription schedule so that you get this buffer time to confirm and verify accuracy. When the start date begins, the subscription changes from scheduled start to live state.
Coupons	If the subscription schedule or subscription has billing cycle anchor in the future and `proration_behavior` set to `none`, updating these objects unsets the coupon. Re-apply the coupon if you make any updates to the subscription schedule or subscription. To migrate a subscription with ongoing `discount_behavior`: Set a future phase that removes the coupon at the correct date instead of waiting for an expiry. Create a coupon for each subscription, with the duration being different on each one so they all expire correctly.
Stripe to Stripe migration	Users can migrate subscriptions within Stripe accounts. You must input Customer IDs and Price IDs (and both Coupon IDs and Tax IDs, if using them) into the template associated with your destination Stripe account, and not your source Stripe account. The migration tool generates an error if you input IDs associated with your source account.

Full CSV specification

Attribute	Type	Description
`customer` (required)	Stripe Customer ID	The identifier of the customer to create the subscription for.
`start_date` (required)	Timestamp in epoch the related setting format	Determines when to create the subscription. You must provide a value that’s 24 hours (or greater) into the future. In a sandbox, you can set this to 1 hour in the future.
`price` (required)	Stripe Price ID	Must be a recurring price. If migrating multiple items, use `items.x.{price, quantity}` format instead. Ad-hoc prices are also supported with `adhoc_items.x.{amount, interval, product, currency}`.
`quantity`	Number	Determines quantity of a subscription. By default, each subscription is for one product, but Stripe allows you to subscribe a customer to multiple quantities of an item.
`items.x.price` (required)	Stripe Price ID	The ID of the price object. Must be a recurring price.
`items.x.quantity`	Number	Determines quantity of a subscription. By default, each subscription is for one product, but Stripe allows you to subscribe a customer to multiple quantities of an item.
`adhoc_items.x.amount` (required)	Number	A positive number. Use full units with decimals (such as 21.50).
`adhoc_items.x.product` (required)	Stripe Product ID	The identifier of the product that belongs with the ad-hoc price.
`adhoc_items.x.interval` (required)	`day`, `week`, `month` or `year`	The billing frequency.
`adhoc_items.x.currency` (required)	String	A three-letter ISO currency code, in lowercase, for a supported currency.
`adhoc_items.x.quantity`	Number	Determines quantity of a subscription. By default, each subscription is for one product, but Stripe allows you to subscribe a customer to multiple quantities of an item.
`metadata_source`	String	If you’re doing a Stripe-to-Stripe migration, enter `internal:Stripe`.
`metadata_*`	String	Attach these key-value pairs to an object. This is useful for storing additional information about the object in a structured format.
`automatic_tax`	Boolean	Specify `true` to use automatic tax settings by Stripe Tax.
`coupon`	Stripe Coupon ID	The identifier of the coupon to apply to this subscription.
`currency`	String	Three-letter ISO currency code, in lowercase. Must be a supported currency. Used for currency selection with multi-currency prices.
`trial_end`	Timestamp	Sets the phase to trial from the start date to the `trial_end` date. You must specify a value that’s before the cycle/phase end date, and you can’t combine it with the trial.
`proration_behavior`	`create_prorations` or `none`	Determines if the subscription creates prorations after migration. The default value is `create_prorations`.
`collection_method`	`charge_automatically` or `send_invoice`	When charging automatically, Stripe attempts to pay the underlying subscription at the end of each billing period using the default source attached to the customer. The default value is `charge_automatically`. When sending an invoice, Stripe emails your customer an invoice with payment instructions and marks the subscription as active. If using `send_invoice`, you must set `days_until_due`.
`default_tax_rate`	Stripe Tax ID	Sets the subscription’s `default_tax_rates`. This also determines the invoice’s `default_tax_rates` for any invoices issued by the subscription during this phase. This value is incompatible with `automatic_tax`.
`backdate_start_date`	Timestamp in epoch the related setting format	Determines the `start_date` of the created subscription, which must occur in the past. If set, you must specify `none` for the `proration_behavior`. Doing so prevents the creation of a pro-rata invoice for the time between `backdate_start_date` and actual `start_date`. For more details, see backdating no charge.
`billing_cycle_anchor`	Timestamp	Determines the future dates of when to bill the subscription to the customer.
`days_until_due`	Integer	The number of days from when the invoice is created until it’s due. This is required and valid only for invoices with `collection_method` set to `send_invoice`.
`cancel_at_period_end`	Boolean	Specify `true` to cancel a subscription at the end of the period.
