Follow Up Boss Custom Field Limits and Your Ace Fields

Updated August 13, 2026

Ace writes a small set of custom fields into Follow Up Boss so your scores and signals live right on the contact. Follow Up Boss limits how many custom fields an account can have, so if you are near that ceiling it helps to know which fields Ace needs and how to make room. This article covers both.

How many custom fields does Follow Up Boss allow?

Follow Up Boss caps the number of custom fields an account can hold. On many plans that ceiling is around 40 fields total, counting every custom field across your whole account — the ones you created, the ones other integrations added, and the ones Ace needs. Your exact limit depends on your Follow Up Boss plan, which you can confirm under Admin → Custom Fields in Follow Up Boss.

Note: The limit is a Follow Up Boss account setting, not an Ace setting. Ace cannot raise it — only your Follow Up Boss plan can.

Which custom fields does Ace use?

Ace maintains a small, consolidated set of custom fields. Two are available on every plan; the rest activate with Ace Trove:

  • Ace Win Score — a calibrated 0–100 win probability (every plan)
  • Ace Churn Risk — Low / Medium / High (every plan)
  • Ace Expected GCI (est.) — win probability × your account's own median commission (Trove)
  • Ace Opportunity — At Risk / Active Buyer / Active Seller / Likely Seller / Nurture (Trove)
  • Ace Seller Tier — the propensity-to-sell tier (Trove)
  • Ace Last Analyzed — when Ace last scored the contact (Trove)

Older Ace field names you may remember (Ace Score, Ace Tier, Ace Status, and a dozen others) were retired in the 2026 field consolidation. Ace no longer writes them and does not re-create them, so if you deleted them they will not come back.

What happens when you hit the limit?

If your Follow Up Boss account is already at its custom-field cap, Follow Up Boss will not let Ace create the fields it needs. Ace keeps scoring your contacts on its own side, but the scores have nowhere to land: the Ace columns on your contacts stay empty, and any Smart List that sorts or filters on them — including the Ace Lists built on Ace Win Score and Ace Churn Risk — will not be available to deploy.

The other reason field creation can fail: permissions

Hitting the cap is not the only thing that blocks it. Follow Up Boss also restricts who may create or change custom fields. If the Follow Up Boss user who connected Ace does not hold that permission, Follow Up Boss refuses the request with “You do not have access to update custom field information” — and Ace cannot override a permission inside your CRM.

To check: in Follow Up Boss, open Admin → Custom Fields and see whether you can add a field. If you cannot, ask your Follow Up Boss account owner either to give your user permission to manage custom fields, or to connect Ace to Follow Up Boss themselves. Then contact support so we can run the field setup again and confirm it worked.

If those fields are missingAt the custom-field cap, or without permission to create them, the scores have nowhere to land and the Ace columns stay empty.
The Ace fields have to exist in Follow Up Boss before any score can land on a contact.

How do I free up custom-field slots?

  1. In Follow Up Boss, go to Admin → Custom Fields.
  2. Review the list for fields you no longer use — old imports, retired integrations, or duplicate fields.
  3. Delete enough unused fields to get below your plan's cap. Deleting a field removes its data, so export anything you want to keep first.
  4. Leave room for Ace's fields listed above (two on every plan, six with Trove).

Once there is space, contact support with your account name and we will run the field setup again and confirm the fields are there — you do not need to reconnect anything. If you would rather not delete fields, upgrading to a Follow Up Boss plan with a higher custom-field limit also solves it.

Heads up: Deleting a Follow Up Boss custom field permanently removes the data stored in it. Export first if you might need it.
