Taxes and Stripe fees are included in both Monthly Recurring Revenue (MRR) and Revenue. Refunds and discounts are excluded.
MRR only includes revenue from subscriptions. Any other charges invoiced with a subscription are excluded, as are all other single purchases.
FirstOfficer.io supports volume-based charging if you have implemented it using Stripe subscription’s quantity field.
Monthly Recurring Revenue shows how much revenue you collected from subscriptions. There are several variations of MRR, like Committed MRR (CMRR). It is non-GAAP metric, so analytics apps may calculate it differently.
