Field catalog update (June 28, 2026): Any references in this article to Ace Score, Ace Tier, Ace Status, Ace Response Time, Ace Velocity Score, Ace Days Since Inbound, or Ace Preferred Channel describe retired FUB custom fields kept only for historical workflow context. Ace no longer creates, writes, or updates those fields. The current catalog has two active free fields: Ace Win Score and Ace Churn Risk, plus five Ace Trove fields: Ace Expected GCI, Ace Opportunity, Ace Seller Tier, Ace Buyer Tier, and Ace Last Analyzed.

Ace AI's 2 Active Free Follow Up Boss Fields

By the Follow Up Ace team· Last updated June 25, 2026

Follow Up Boss contact record showing Ace Win Score and Ace Churn Risk

Quick answer

Follow Up Ace currently writes two free predictive fields to Follow Up Boss: Ace Win Score (a 0–100 within-account percentile rank) and Ace Churn Risk (Low, Medium, or High). The seven older field names documented later in this article are retired historical fields and are no longer created, written, or updated.

Ace keeps the Follow Up Boss field surface intentionally small. It publishes model outputs that are useful for native sorting and filtering, while live explanations, recent-channel context, and next-step suggestions stay in Companion and the dashboards.

Which fields are free?

Field	Meaning	Valid workflow
Ace Win Score `customAceWinScore`	Numeric 0–100 within-account percentile rank of calibrated win probability; not a close probability.	Sort descending, then review the contact evidence.
Ace Churn Risk `customAceChurnRisk`	Low / Medium / High model risk that an engaged contact goes cold.	Filter High for an agent-reviewed save-list.

Which fields require Ace Trove?

Ace Expected GCI (customAceExpectedGCI) — calibrated win probability multiplied by the account's median commission, always treated as an estimate.
Ace Opportunity (customAceOpportunity) — At Risk / Active Buyer / Active Seller / Likely Seller / Nurture.
Ace Seller Tier (customAceSellerTier) — relative seller-propensity band.
Ace Buyer Tier (customAceBuyerTier) — relative buyer-propensity band, not a guarantee.
Ace Last Analyzed (customAceLastAnalyzed) — date of the most recent completed analysis.

How do the fields update?

Field delivery follows the account scoring cadence. Meaningful CRM activity can schedule a debounced refresh, but receiving a webhook is not proof that scoring completed or that a value reached Follow Up Boss. Unsupported or stale model outputs remain blank instead of being invented.

How should agents and team leads use them?

Priority review: sort numeric Ace Win Score descending. It has no temperature categories.
Save-list: filter Ace Churn Risk = High, then inspect current stage, activity, consent, and relationship context.
Trove segmentation: filter Ace Opportunity or the buyer/seller tiers, then review the supporting evidence before outreach.
Freshness: use Ace Last Analyzed and the displayed pipeline state; do not treat a missing value as zero.

Where did the older field names go?

The seven heuristic free-field names documented in the original June 2026 version of this article were retired during consolidation. Their useful signals may still inform internal models and live dashboards, but Ace no longer creates or writes those retired FUB fields. Rebuild old temperature lists by sorting Ace Win Score descending, and rebuild save-lists with Ace Churn Risk.

How do I enable field delivery?

Connect Follow Up Boss through the Ace onboarding flow.
Have the Follow Up Boss account owner authorize custom-field creation. Follow Up Boss restricts custom-field creation to the account owner.
Confirm the two free fields appear and that the Ace pipeline reports completed structural verification.
If Ace Trove is active, confirm the five Trove definitions and wait for supported analysis output.
