Overview
Effort structures CRM data around contacts (with role-based associations), companies, and deals — storing custom fields per object alongside activity logs for calls, emails, and meetings. Twenty CRM exposes a relational data model built on People, Companies, Opportunities, Tasks, and Notes, with custom fields and custom objects configurable through its Settings → Data Model interface before any data lands. We map Effort contacts to Twenty People, Effort companies to Twenty Companies, and Effort deals to Twenty Opportunities — handling foreign-key resolution so companyId links point to valid Twenty records. Activity history migrates as Twenty Tasks or Notes with original timestamps and linked record references preserved. Owner resolution matches Effort owner emails to Twenty Workspace Members; unmatched owners are flagged before migration so no record lands without an assignee. Custom fields that have no direct Twenty equivalent are flagged as custom_field_required and surfaced in the pre-migration setup plan so your Twenty workspace is ready before import begins. We run a sample migration first, then the full run, with a 24–48 hour delta pickup window capturing in-flight changes. A full audit log and one-click rollback are included so you can verify reconciliation before go-live.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Effort object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Effort
Contact
Twenty CRM
People
1:1Effort Contact maps directly to Twenty People. Twenty requires an email for uniqueness; contacts without an email are flagged before migration and assigned a placeholder email field so uniqueness checks pass. Effort contact associations to multiple companies collapse to one primary companyId on the Twenty People record, with secondary companies surfaced as a custom field.
Effort
Company
Twenty CRM
Companies
1:1Effort Company maps to Twenty Companies with a direct field-level correspondence. Parent-company hierarchies in Effort map to Twenty's ParentId relationship field. Multi-company structures that rely on Effort's N:N association model require flattening to one primary company per contact in Twenty.
Effort
Deal
Twenty CRM
Opportunity
1:1Effort Deal maps to Twenty Opportunity. Each Opportunity's name, amount, close date, and stage are mapped field-by-field. Effort's pipeline stages translate to Twenty stage pick-list values configured in Settings → Data Model before import. Amount is stored as a currency-formatted number in Twenty's amount field.
Effort
Call / Email / Meeting
Twenty CRM
Task / Note
1:1Effort's call, email, and meeting activity logs map to Twenty Tasks (for calls and emails) and Notes (for meeting summaries). Original timestamps, owner email references, and linked People or Company IDs are preserved. Meeting descriptions and call notes migrate as Note body text linked to the relevant People or Company record.
Effort
Custom Field (per object)
Twenty CRM
Custom Field
1:1Effort custom fields map to Twenty custom fields created via Settings → Data Model before import. Every custom field used in Effort must be pre-created in Twenty with the matching field type (text, number, date, select, multi-select, relation) so the CSV import can write values into the correct columns. FlitStack delivers a pre-migration setup checklist naming each custom field to create.
Effort
Custom Object
Twenty CRM
Custom Object
1:1Effort custom objects map 1:1 to Twenty custom objects. Custom-object relationships in Effort that use an N:N association model need Twenty junction objects when the relationship is many-to-many. FlitStack surfaces these in the migration plan so junction objects can be created before the custom-object import batch runs.
Effort
User / Owner
Twenty CRM
Workspace Member
1:1Effort owner records resolve by email match against Twenty Workspace Members. Unmatched owners are flagged before migration — your team either invites them to Twenty first or assigns their records to a fallback Workspace Member. No record lands without a valid Twenty owner reference.
Effort
Attachment / File
Twenty CRM
Attachment
1:1Effort file attachments on records re-upload to Twenty as attachments linked to the corresponding People, Company, or Opportunity record. File size limits apply per Twenty's upload configuration. Inline images embedded in Effort notes are extracted, rehosted, and linked in Twenty Notes.
Effort
Role / Association Label
Twenty CRM
Relation / Custom Field
1:1Effort role labels on contact-company or contact-deal associations (e.g., Decision Maker, Influencer) have no built-in Twenty equivalent. We map these to a custom pick-list field on the People record or a custom relation object, depending on the association cardinality. The mapping approach is confirmed with you before migration runs.
Effort
Sequence / Automation Rule
Twenty CRM
Workflow (rebuild required)
1:1Effort sequences and automation rules do not export in a portable format. We document your Effort automation definitions — triggers, actions, timing rules, and conditional branches — as a structured rebuild reference. Your Twenty admin uses this to reconstruct workflows in Twenty's workflow builder or a third-party sequencing tool after migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Effort gotchas
No documented public API or bulk export endpoint
iOS compatibility issues cause field data gaps
Form schema is customer-defined, not standard
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Audit Effort data and build the field-mapping document
FlitStack exports all Effort objects via the platform's API — contacts, companies, deals, activity logs, custom objects, and custom fields — and profiles the dataset for duplicates, missing required fields, and data-quality issues. We build a field-mapping document that pairs every Effort field to its Twenty equivalent, naming the field type in Twenty's Settings → Data Model for each custom field that must be pre-created. This document is your Twenty setup checklist before the import runs.
Create Twenty custom fields and resolve Workspace Members
Your Twenty admin (or our team) creates all custom fields named in the mapping document via Settings → Data Model, configuring field types and pick-list options to match Effort's schema. Simultaneously, Workspace Members in Twenty must exist before owner resolution can map — FlitStack matches Effort owner emails to Twenty Workspace Members and flags any owners who have not yet accepted their Twenty invitation so the team can invite them before migration day.
Run the sample migration with field-level diff
A representative slice of Effort data — typically 100–500 records covering contacts, companies, deals, and activities — migrates into Twenty first. We generate a field-level diff comparing source values in Effort against the resulting field values in Twenty, verifying that custom field mappings resolved correctly, foreign keys (companyId, personId) point to valid Twenty records, and owner assignments matched. You review the diff and confirm the mapping before the full run commits.
Execute the full migration with delta-pickup window
The full dataset migrates from Effort to Twenty with records processed in dependency order — Companies first, then People, then Opportunities, then custom objects and activities. A delta-pickup window of 24–48 hours after the full run captures any records created or modified in Effort during the cutover period. The FlitStack audit log records every record that moved, its source ID, and its destination ID, so you can reconcile against Effort's final record counts at go-live.
Verify record counts and validate rollback
After the delta pickup closes, FlitStack generates a reconciliation report comparing Effort's final record counts (after delta capture) against Twenty's imported record counts for each object. You verify that no records are missing and that field values look correct across a sample of the migrated data. The rollback procedure is tested against a staging snapshot so your team knows exactly what a rollback entails before you officially cut over from Effort to Twenty.
