Set up your unit
Open Settings → Breakdowns and counting → Count customers by:- Give the unit a name, such as Shops, Stores or Seats.
- Pick the subscription metadata key that identifies it, such as
storeId. OneMRR suggests keys from your data. Each Shopify shop is always one unit. - Choose what happens when a subscription doesn’t have the key: count it with its billing customer, or count each subscription on its own.

Switch what pages count
Once a unit is set up, everyone can choose Count by in the filter bar: Customers, your unit, or Subscriptions. OneMRR remembers each person’s choice. It applies everywhere: paying counts, the MRR bridge, churn rates, ARPA and LTV, cohorts, the Customers list and What changed.
