What it is
CRM ARR is recurring value inferred from CRM — opportunity amounts, account ARR fields, or products on closed-won deals. It is excellent for sales forecasting and terrible as an unreconciled board source of truth.
How it’s calculated
Usually rolled from opportunity line products or a rolled-up account ARR field. Without tight stage and product hygiene, the number is a sales model — not a certified period metric.
Where it breaks
CRM ARR breaks on stale open opps counted as won, products that never bill, multi-year ACV mistaken for ARR, and account fields updated by hand. Boards get burned when CRM ARR is pasted into the pack without a billing reconcile.
In the board pack
Use CRM ARR for pipeline and bookings context. Certify board ending ARR from billing ARR (or a documented hybrid) and show the CRM-to-billing bridge when leadership asks why the numbers differ.
