About

Stripe subscriptions can now have multiple plans per subscription. Many of you have multiple subscriptions per customer. This tool will combine those subscriptions into a single subscription. Now your customer will only be charged once!

Install

The easiest way to use submigrate is to download a pre-built binary.

• OS X
• Windows
• Linux

You can also install using the Go tool.

go get github.com/stripe/submigrate

Usage

submigrate takes a list of subscription IDs. submigrate is safe to run by default; no actions will taken. You'll see logging explaining what would have happened.

$ submigration -key <key> sub_9HmVS3IUUUVGYZ sub_9GbdjrGBMXCEaj
-----> Beginning subscription migration in <dryrun> mode

-----> Fetching requested subscriptions
       Getting subscription sub_9HmVS3IUUUVGYZ
       Getting subscription sub_9GbdjrGBMXCEaj
       Successfully fetched subscriptions

-----> Filtering out canceled subscriptions
       Ignoring canceled subscription sub_9HmVS3IUUUVGYZ

-----> Marking migration as complete
       Subscription sub_9GbdjrGBMXCEaj is active and all other subscriptions are canceled

If the proposed changes look reasonable, pass the -run flag to begin the migration. submigrate is also idempotent; it's safe to run multiple times.

Migration Strategy

In order to group existing subscriptions into one subscription, submigrate will pick one subscription to be your primary subscription. Then, it will cancel all the other subscriptions and add the plans of those subscriptions on to the primary subscription.

Since the subscription will bill all items together, all the plans you are grouping together must have the same interval and currency. Also, the plans cannot have trial period days set.

When switching plans from one subscription to another, submigrate will generate proration items for the difference between the end date of the existing subscription and the end date of the primary subscription.

First, we pick the subscription with the maximum current_period_end to be the primary subscription.

For each other subscription, add a new item to primary subscription with the same plan and quantity as the existing subscription.

Lastly, cancel all subscriptions other than the primary subscription.

For example, saw we have a customer with three subscriptions for $20/month, $10/month and $5/month. We'll use the $20/month subscription as the primary because its period ends last.

After migration, we'll have one subscription (with three items) for $35/month. The next billing cycle will also include two proration items for the unpaid periods between the two canceled subscriptions.
