Overview
Sercom's CRM suite stores contacts, accounts, deals, tasks, and notes with custom properties — a data model comparable to Twenty's standard objects (People, Companies, Opportunities, Tasks, Notes) plus custom objects. The migration loads Sercom data into Twenty's workspace using CSV import (or Twenty's REST/GraphQL API for large datasets), respecting Twenty's required import order: Companies first, then People, then Opportunities, then custom objects. FlitStack AI extracts Sercom's standard object fields (firstname, lastname, email, phone, jobtitle, address, dealname, amount, dealstage, closedate) and Sercom's custom fields (source_system_id, original_create_date, custom properties) and maps them into Twenty's People, Companies, and Opportunities objects. Tasks and Notes land in Twenty with their subject, body, assignee relation, and original timestamps preserved. Sercom's workflows, automations, sequences, and permission sets do not migrate — they must be rebuilt in Twenty's workflow builder and Settings → Permissions. The migration mechanism uses scoped read access on Sercom and Twenty's API (100 req/min on Pro, 200 req/min on Organization) with rate-limit-aware batching. A 24–48 hour delta-pickup window captures in-flight changes during cutover, and an audit log plus one-click rollback covers reconciliation failures.
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 Sercom 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.
Sercom
Contact
Twenty CRM
People
1:1Sercom Contact maps to Twenty's People object. The People object stores name, email, phone, job title, and a companyId relation. Sercom contacts without a primary company land in Twenty People with no companyId — that relation is resolved during the import pass once all Company records exist.
Sercom
Account
Twenty CRM
Companies
1:1Sercom Account maps to Twenty's Companies object. Companies must be imported before People because People records carry a companyId foreign key. FlitStack AI sequences the import so all Accounts resolve to Twenty Companies before any Contact-to-People record is written. This ordering ensures that every People record receives a valid companyId reference rather than a null or broken link.
Sercom
Deal
Twenty CRM
Opportunities
1:1Sercom Deal maps to Twenty's Opportunities object. Opportunities store deal name, amount, stage, probability, expectedCloseDate, and linked companyId and personId relations. Opportunities import third in sequence after Companies and People because they carry two foreign keys that must resolve to already-existing records.
Sercom
Task
Twenty CRM
Tasks
1:1Sercom Task maps to Twenty's Tasks object. Tasks carry a name, status, dueDate, completedAt timestamp, and a workspaceMemberId relation for the assignee. Tasks can be linked to any record (People, Companies, Opportunities) via Twenty's generic relation model. Original create and update timestamps are preserved as custom fields since Twenty's Tasks object does not expose custom datetime fields natively.
Sercom
Note
Twenty CRM
Notes
1:1Sercom Note maps to Twenty's Notes object. Notes store a body (rich-text content) and can be attached to People, Companies, Opportunities, or other records. FlitStack AI preserves the original createdAt timestamp as a custom field and maintains the parent-record link so note context is not lost during the migration.
Sercom
Contact custom fields
Twenty CRM
People custom fields
1:1Sercom's custom fields on Contact (such as source_system_id, original_create_date, or any industry-specific pick-list) require pre-creation in Twenty's Settings → Data Model before the CSV import. FlitStack AI generates a field-creation checklist based on Sercom's custom field inventory so Twenty's schema is ready before data lands.
Sercom
Account custom fields
Twenty CRM
Companies custom fields
1:1Sercom's custom fields on Account migrate to Twenty Companies custom fields. Fields like annual_revenue, number_of_employees, and industry (where not matched to Twenty's standard pick-list) are created in Twenty Settings → Data Model first. Custom pick-list options are preserved as written values rather than enforced enums since Twenty's select fields are configurable post-import.
Sercom
Deal custom fields
Twenty CRM
Opportunities custom fields
1:1Sercom's custom fields on Deal (deal_priority, probability, custom revenue fields) migrate as Twenty Opportunities custom fields. The field type is carried over (number, text, select) and pre-created in Settings → Data Model. Probability and deal_priority are stored as custom number and select fields respectively since Twenty Opportunities does not expose these natively.
Sercom
Sercom custom objects
Twenty CRM
Twenty custom objects
1:1Sercom custom objects map 1:1 to Twenty custom objects. Custom object definitions (name, field list, field types) are extracted from Sercom and translated into Twenty's metadata API format. Custom object associations that use a many-to-many model in Sercom need a junction object in Twenty — FlitStack AI surfaces this in the pre-migration plan.
Sercom
Attachment / File
Twenty CRM
Note attachments or URL field
1:1Sercom file attachments linked to records are preserved as external URLs in a custom text field (File_URL__c) pointing to the original storage location, or re-uploaded to Twenty's connected storage. Files that are inline in notes are extracted, downloaded, and stored as attachments in Twenty's file management system.
Sercom
User / Owner
Twenty CRM
WorkspaceMember
1:1Sercom owner records (sales reps assigned to contacts, deals, and tasks) resolve by email match against Twenty WorkspaceMembers. Unmatched owners are flagged before migration — the team either creates the Twenty user first or assigns records to a fallback WorkspaceMember. Owner resolution is required before the People import pass runs.
Sercom
Activity history
Twenty CRM
Tasks / Notes
1:1Sercom's call logs, meeting records, and email history (where stored as activity objects rather than notes) migrate as Twenty Tasks with the activity type preserved in a custom field (Activity_Type__c). Original timestamps and assignee information are carried forward. This assumes Sercom exposes these activity records via its export or API.

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.
Sercom gotchas
No public Sercom migration documentation or API reference
Custom field schema is entirely tenant-defined
Historical Work Order records may lack referential integrity
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 Sercom data and set up Twenty workspace
FlitStack AI connects to Sercom via scoped read access and exports a full inventory of all standard and custom objects, fields, and pick-list values. We cross-reference this against Twenty's standard object model (People, Companies, Opportunities, Tasks, Notes) and identify which Sercom fields require custom field creation in Settings → Data Model. The output is a field-creation checklist with exact field names, types, and pick-list options — your admin creates these in Twenty before the import begins.
Invite Twenty users and resolve owners by email
Twenty requires all users referenced in imported records to exist before the import pass. FlitStack AI resolves Sercom owner and assignee IDs by email match against Twenty WorkspaceMembers. Any Sercom owner without a corresponding Twenty user is flagged before migration — your team either invites the user to Twenty first or assigns records to a fallback WorkspaceMember. No record with an owner reference lands without a valid destination user.
Import Companies first, then People, then Opportunities
FlitStack AI sequences the migration in Twenty's required order: Companies → People → Opportunities → Tasks → Notes → Custom Objects. The companyId foreign key on People and the companyId and personId foreign keys on Opportunities require target records to exist before the references are written. Tasks and Notes are imported last because they carry relation fields pointing to any object. This ordering prevents orphaned records and broken parent-child links.
Run a sample migration with field-level diff
A representative slice of records (typically 200–500 spanning People, Companies, Opportunities, Tasks, and Notes) migrates first using Twenty's CSV import mechanism. FlitStack AI generates a field-level diff between the Sercom source and the Twenty result, verifying that email maps to email, phone maps to phone, stage maps via value mapping, companyId resolves correctly, and custom field values land in the correct custom field. You review the diff before the full run commits.
Cut over with delta-pickup for in-flight records
The full migration runs against Twenty using the sequenced import. A delta-pickup window of 24–48 hours captures any records created or modified in Sercom during the cutover period. All operations are logged to an audit trail. If reconciliation reveals missing records or broken relations, one-click rollback reverts the Twenty workspace to its pre-migration state. The rollback uses a snapshot taken before the first import pass so no Sercom data is overwritten permanently.
Deliver workflow reference and post-migration verification
After the migration, FlitStack AI delivers a workflow reference export documenting every Sercom automation, trigger, and sequence with its configuration parameters. Your Twenty admin uses this as a rebuild checklist for the workflow builder. A final verification report confirms record counts per object, foreign key resolution rates, and a spot-check of field values in Twenty against the Sercom source export. Custom field creation for any fields missed in the initial setup is handled as a correction pass before go-live.
