Overview
Fello stores contacts with enriched property intelligence, lead scores, and owner assignments across pipeline stages tied to listing opportunities. Twenty CRM provides a People object for contacts, a Companies object for organizations, and an Opportunities object for deals — with custom fields available for Fello's proprietary scoring and enrichment data. We map Fello contacts to Twenty People, Fello companies to Twenty Companies, and Fello pipeline deals to Twenty Opportunities. Fello IQ lead scores migrate as a custom number field on People. Owner resolution happens by email match against Twenty workspace members before migration. Fello smart workflows, sequences, and automation rules must be rebuilt manually in Twenty's workflow builder (Organization tier) or via API — we export the workflow definitions as a reference document. The migration runs via CSV export from Fello and bulk import into Twenty, with a 24–48 hour delta pickup window capturing any in-flight changes during cutover. After the bulk import completes, we run a reconciliation pass comparing record counts and field population rates against the source Fello export, flagging any owner gaps or unmapped enrichment fields for manual resolution.
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 Fello 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.
Fello
Contact
Twenty CRM
People
1:1Fello contacts map directly to Twenty People. Every contact property (name, email, phone, address) transfers to the corresponding Twenty People fields. Fello's owner assignment resolves by email match against Twenty workspace members — unmatched owners flag for manual assignment before the full migration runs.
Fello
Contact.enrichment_data
Twenty CRM
People (custom fields)
1:1Fello stores property intelligence, ownership records, and home value estimates as enrichment data on contacts. These map to custom fields on Twenty People (e.g., Property_Value_Estimate__c, Last_Listed_Date__c). Custom fields must be pre-created in Twenty Settings → Data Model before import; FlitStack delivers the field creation plan.
Fello
Contact.fello_iq_score
Twenty CRM
People.lead_score (custom field)
1:1Fello IQ assigns a 0–100 lead score per contact. Twenty has no native lead scoring field. We create a custom number field (Lead_Score__c) on People and populate it during migration. The scoring logic itself (what triggers score changes) must be rebuilt in Twenty's workflow builder or a third-party sequencing tool.
Fello
Company
Twenty CRM
Companies
1:1Fello companies map to Twenty Companies object. Company name, domain, industry, employee count, and annual revenue transfer to the corresponding Twenty Companies fields. Multi-contact companies in Fello collapse to one primary Company record in Twenty with multiple related People records linked via company_id.
Fello
Deal
Twenty CRM
Opportunities
1:1Fello deals map to Twenty Opportunities. Deal name, amount, stage, close date, and owner transfer to the corresponding Twenty Opportunities fields. Fello pipeline names map to Twenty stage values — we deliver a value-by-value stage mapping plan before migration begins.
Fello
Deal.stage
Twenty CRM
Opportunities.stage
1:1Fello pipeline stages (e.g., Prospecting, Active Listing, Under Contract, Closed Won) map to Twenty Opportunity stage pick-list values. Each pipeline in Fello requires a corresponding stage list in Twenty. Stage probability and forecast category re-applied from Twenty-side configuration as part of the migration.
Fello
Activity (call, email, meeting, note)
Twenty CRM
Tasks / Notes
1:1Fello engagement activities — calls, emails, meetings, and notes — map to Twenty Tasks and Notes. Original timestamps, owners, and parent-record links (contact, company, deal) are preserved. Fello note body text transfers to Twenty Note body. Call and email type recorded in the Task Type field for filtering.
Fello
Owner / Agent
Twenty CRM
Workspace Member
1:1Fello owner records (agents) resolve to Twenty workspace members by email match. All team members must accept their Twenty invitations and appear in Settings → Members before migration so owner lookups resolve correctly. Unmatched owners flagged pre-migration; records assigned to a fallback owner.
Fello
Smart Workflow / Sequence
Twenty CRM
No equivalent
1:1Fello Smart Workflows and drip sequences do not migrate — they run on Fello's automation engine. We export workflow definitions (trigger conditions, step actions, timing rules) as a JSON reference document for rebuilding in Twenty's workflow builder or a third-party sequencing tool (e.g., Instantly, SmartReach).
Fello
Attachment / File
Twenty CRM
Note attachments
1:1Fello file attachments on contacts, companies, or deals re-upload as attachments on the corresponding Twenty Notes. File size limits on Twenty apply (standard upload limits apply). Inline images in notes are downloaded and re-hosted as part of the migration process.

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.
Fello gotchas
No public API — all data export is CSV only
Automation workflows must be manually rebuilt
Contact export requires filtering before export job
Lead score is Fello-computed and proprietary
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 Fello data and invite Twenty workspace members
We export a full snapshot of your Fello data — contacts, companies, opportunities, activities, enrichment fields, and owner assignments. In parallel, we audit your Fello workflow definitions for the rebuild reference document. You ensure all Fello agents have accepted their Twenty invitations and appear in Settings → Members so owner lookups resolve at migration time. We flag any Fello owner without a corresponding Twenty user for fallback assignment.
Create Twenty custom fields and prepare the field mapping plan
Based on your Fello enrichment field inventory, we deliver a field creation plan specifying every custom field needed on Twenty's People object (Lead_Score__c, Property_Value_Estimate__c, Owner_Type__c, Last_Listed_Date__c, etc.). You create these fields in Settings → Data Model before the migration import. We finalize the value-by-value stage mapping for Fello pipelines to Twenty Opportunity stages and confirm the mapping with you before proceeding.
Run a sample migration with field-level diff
We migrate a representative slice — typically 200–500 records spanning contacts, companies, opportunities, and activities. The field-level diff compares source values against destination field values, verifying that enrichment fields populated correctly, lead scores landed in Lead_Score__c, owner assignments resolved, and stage names mapped per the agreed plan. You review the diff and sample records and approve before the full migration commits.
Execute full migration with delta-pickup window
The full migration runs against your Twenty instance. A delta-pickup window (24–48 hours) captures any Fello records created or modified during the cutover so Twenty reflects your final Fello state at go-live. All operations are logged in an audit trail. One-click rollback is available if reconciliation finds unexpected gaps. We deliver a post-migration report showing record counts, owner resolution rates, and any unmapped fields requiring manual attention.
Deliver workflow rebuild reference and post-migration support
We deliver the Fello workflow definitions as a JSON reference document with trigger conditions, step timing, enrollment criteria, and action sequence documented for your Twenty admin. Post-migration support is available for 14 days to address data issues, answer mapping questions, and assist with any gaps discovered during user acceptance testing in Twenty.
