Frequently asked questions

What is the difference between ARR and MRR?
MRR (Monthly Recurring Revenue) is the monthly view; ARR (Annual Recurring Revenue) is the annualised view. ARR = MRR × 12. Both measure the same recurring revenue stream but at different cadences.
Does ARR include one-time fees?
No. ARR only includes normalised, predictable recurring revenue. One-time implementation fees, professional services, and non-recurring charges are excluded because they do not recur.
