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.

FAQs
What happens when subscriptions are merged with an out of stock product?
The merged subscription doesn’t check or behave differently with the out of stock product during the merge.
What happens when subscriptions are merged with different intervals?
The merged subscription inherits the interval of the subscription where Merge was initiated. For example, merging Subscription 1 (4 weeks) with Subscription 2 (6 weeks) by pressing Merge on Subscription 1 will result in a 4-week interval. This gives customers control over which interval carries forward.
