Subtasks in ClickUp

Subtasks in ClickUp

ClickUp does not natively roll up numerical custom field values from subtasks to parent tasks. ClickUp's native rollup field handles time tracked and time estimated only not custom number fields, formulas, or currency. This has been a top ClickUp community feature request since 2020 and is still not on the committed roadmap as of November 2025. ClickBridge is a no-code tool that aggregates subtask values automatically and writes them back to parent tasks.

The problem

The problem

ClickUp cannot sum, average, or aggregate custom number field values across subtasks'

Parent-level reporting on subtask totals is impossible without an external tool

Currency, formula, and date subtask aggregates are also unsupported

Existing workarounds (and why they break)

Existing workarounds (and why they break)

Zapier or Make: requires a trigger on every subtask change, a lookup, a sum step, and a write-back. Each step is a paid task. Flows break silently when ClickUp's API changes.

Manual exports: outdated the moment they're generated. Doesn't scale.

Spreadsheet formulas: only work outside ClickUp, and you have to re-export every time.

The ClickBridge solution

The ClickBridge solution

ClickBridge reads all subtasks of a parent task, aggregates the numerical custom field values you select, and writes the result to a designated field on the parent. It runs on a schedule, handles closed and nested subtasks, and updates whenever subtask values change.

"This feature is on our radar, but not on the committed roadmap at this time."

Combine with Google Sheets sync

Once subtask values are rolled up to parent tasks, you can sync the parent tasks (with rollup totals) to Google Sheets in one pipeline. Build live dashboards, billing reports, and status views without leaving the ClickUp data layer.

Can ClickUp sum custom field values from subtasks?

No. ClickUp's native rollup field handles time tracked and time estimated, but it does not aggregate numerical custom fields, formulas, or currency from subtasks to parent tasks. The feature has been requested since 2020 and is still not on ClickUp's committed roadmap as of November 2025.
