For subscription businesses, the first payment is a fraction of the value. What matters is which channels bring subscribers who stay.
Orders sharing a subscription id are grouped automatically: Stripe and GoHighLevel subscriptions, PayPal billing agreements, systeme.io and ClickFunnels plans, or a subscription_id you send via the API. A subscription is active while its last payment is within the chosen window, and MRR is the sum of each active subscription's latest payment. You also get new and churned subscriptions, rebills and rebill revenue, and active subscriptions and MRR by first-touch channel.
