What does it mean to merge or split subscriptions?
Merging subscriptions combines multiple active subscriptions for the same customer into one. This helps reduce fulfillment complexity by creating a single bill and shipment for all products in the merged subscription.
Splitting a subscription does the opposite: it separates products from one subscription into multiple subscriptions. This gives customers more flexibility (for example, if they want different items shipped to different addresses or on different dates).
Both options give you more control over how subscriptions are managed on behalf of your customers, while keeping operations streamlined.

Once enabled, a "merge subscription" option appears in the customer portal. Here are the steps a user would take to merge their subscription:
Select “Merge subscription”

Pick one or more subscriptions to merge into the current subscription

FAQs
What happens when subscriptions are merged with an out of stock product?
The merged subscription doesn’t check or behave differently with the OOS product during the merger.
What happens when subscriptions are merged with different intervals?
For example, we merge Subscription 1 (4 weeks) with Subscription 2 (6 weeks). The merged subscription will take on the interval of whatever Subscription 1 is (The subscription where the "merge" button was pressed.) This gives you the ability to pick any interval between the subscriptions being merged.
