Overview

What this migration involves

Fame Service stores contacts, companies, deals, and activity history in a proprietary schema that varies by setup. Twenty CRM exposes a structured People object for contacts, Companies object for accounts, Opportunities object for deals, and a flexible custom-object layer accessible via REST and GraphQL. FlitStack AI extracts Fame Service data through API calls and CSV exports, transforms field names and pick-list values to Twenty conventions, and loads records through Twenty's import API with a defined sequence — Companies first, then People, then Opportunities. Owner resolution runs against Twenty users by email match. Workflows, automations, and email templates do not carry over and must be rebuilt manually using Twenty's workflow builder — we export the definitions as a reference document for your admin team. A delta-pickup window captures any records modified in Fame Service during the cutover window, and audit logs document every operation with a one-click rollback available if reconciliation fails.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Fame Service

What's pushing teams away

  • Reviewers describe the interface as clunky and not intuitive, with a steep learning curve where the software 'has trouble keeping up' if users aren't careful — onboarding is documented as a multi-week effort.
  • Mobile app requires connectivity to function, which is problematic for technicians working in basements, rural sites, or industrial facilities with poor cell coverage.
  • Implementation is heavy because Fame Service ties material sales, service, and rental into a single ledger — disconnecting one module post-rollout is non-trivial.
  • Public pricing is opaque, with no published rate card — every quote requires a sales conversation, which slows side-by-side evaluation against ServiceTitan, Jobber, or BuildOps.
  • Customer base skews toward established industrial distributors and equipment dealers; smaller HVAC/plumbing/electrical contractors often find the platform overbuilt and migrate to lighter FSM tools like Housecall Pro or Jobber.

Choosing

Twenty CRM logo

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Fame Service objects map to Twenty CRM

Each row shows how a Fame Service 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.

Fame Service

Contact / Person

maps to

Twenty CRM

People

1:1
Fully supported

Fame Service contacts map to Twenty's People object, which stores name, email, phone, and job title as standard fields. Phone numbers may require formatting normalization if Fame Service uses inconsistent delimiters. A primary company association maps to the companyId relation — Twenty requires the Company record to exist before People records load.

Fame Service

Company / Organization

maps to

Twenty CRM

Company

1:1
Fully supported

Fame Service companies map directly to Twenty's Companies object. Company name, domain, industry, employee count, and annual revenue are standard fields in both platforms. Parent-company hierarchies map to the relation field in Twenty — the parent company must migrate first or FlitStack flags circular references before loading.

Fame Service

Deal / Opportunity

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Fame Service deals map to Twenty's Opportunities object. Deal name, amount, expected close date, and stage status transfer directly. Stage values in Fame Service may not align with Twenty's Opportunities stage — a value-mapping table is created during planning that maps each Fame Service stage name to the corresponding Twenty stage or custom select option.

Fame Service

Custom Field (People-level)

maps to

Twenty CRM

People custom field

1:1
Fully supported

Fame Service custom properties on contacts (such as source, lead grade, or custom pick-lists) migrate as Twenty custom fields on the People object. These must be pre-created in Settings → Data Model before the migration runs, because Twenty does not allow field-type changes after records exist. FlitStack delivers a field-creation checklist as part of the setup plan.

Fame Service

Custom Field (Deal-level)

maps to

Twenty CRM

Opportunity custom field

1:1
Fully supported

Fame Service custom deal properties — deal priority, probability overrides, product lines — migrate as custom fields on Twenty's Opportunities object. Any pick-list values in Fame Service need to be replicated as select options in Twenty's field configuration. FlitStack captures the full pick-list value set during the data audit phase.

Fame Service

Activity (Call / Email / Meeting)

maps to

Twenty CRM

Task

1:1
Fully supported

Fame Service activity history — logged calls, emails, and meetings — maps to Twenty Tasks. Each activity type becomes a Task with a Type field set to the activity kind, the subject populated from the Fame Service activity title or first line, and original timestamp preserved. If Fame Service stores rich-body email content, it migrates to the Task body field.

Fame Service

Note / Free-text Note

maps to

Twenty CRM

Note

1:1
Fully supported

Fame Service notes migrate to Twenty's Notes object, which can be attached to People, Companies, Opportunities, or any custom object. Rich-text formatting is preserved where Fame Service exposes it. Notes are linked to the parent record via Twenty's relation model, which requires the parent record to exist first.

Fame Service

Task / To-do

maps to

Twenty CRM

Task

1:1
Fully supported

Fame Service tasks and to-do items map 1:1 to Twenty Tasks. The Task subject, due date, completion status, and assigned user transfer directly. Owner resolution by email applies here — the task assignee must exist in Twenty as a workspace member for the assignment to map cleanly.

Fame Service

Attachment / File

maps to

Twenty CRM

File (attached storage)

1:1
Fully supported

Fame Service file attachments re-upload to Twenty's attached-storage layer. Inline images embedded in notes are downloaded and rehosted. File size limits apply — Fame Service files above 25MB are flagged before migration, and the team decides whether to split attachments or exclude oversized files from the migration batch.

Fame Service

Owner / User assignment

maps to

Twenty CRM

Workspace Member

1:1
Fully supported

Fame Service owner assignments on contacts, companies, and deals are resolved by matching the owner email address against Twenty workspace members. Unmatched owners are flagged before migration — the team either invites the user to Twenty first or assigns records to a designated fallback owner. No record lands in Twenty without a resolved owner.

Fame Service

Custom Object (Enterprise)

maps to

Twenty CRM

Custom Object

1:1
Fully supported

Fame Service custom objects migrate to Twenty custom objects if the destination supports the object type. Custom-object associations that use an N:N relationship model in Fame Service require a junction object in Twenty — FlitStack surfaces this in the migration plan and the admin decides whether to recreate every relationship label or collapse them.

Fame Service

Workflow / Automation

maps to

Twenty CRM

None

1:1
Fully supported

Fame Service workflow rules and automation sequences do not have a direct equivalent in Twenty CRM's workflow builder. Automations are business logic specific to Fame Service's execution model and cannot be exported as data. FlitStack exports the workflow definitions as a structured reference document for the admin to rebuild in Twenty's workflow builder on Pro or Organization tiers.

Fame Service

Sequence / Email Sequence

maps to

Twenty CRM

None

1:1
Fully supported

Fame Service email sequences and cadence rules do not migrate. Twenty CRM does not ship a native sequencing module — teams that rely on sequences for outbound cadences use third-party sales engagement tools connected via the Twenty API. FlitStack documents the sequence structure (step order, delay rules, exit conditions) as a rebuild reference.

Fame Service

Integration / Third-party connection

maps to

Twenty CRM

None

1:1
Fully supported

Fame Service integrations with billing systems, telephony, or marketing tools have no equivalent in Twenty CRM and do not carry over. Each connected system must be re-linked using Twenty's REST API or a middleware tool. FlitStack provides a connection audit list showing every active Fame Service integration for the admin to prioritize during post-migration setup.

Pair-specific challenges

  • Twenty's field-first schema requirement blocks late custom-field creation

    Twenty CRM requires all custom fields to exist in Settings → Data Model before any records are imported. If a custom field is missed during setup, the import fails for records using that field, or data lands without it and the field cannot be retroactively typed correctly. FlitStack audits Fame Service custom field definitions in the first phase and delivers a field-creation checklist with field types, pick-list values, and required/unique flags — the admin creates these in Twenty before the migration run. This is a hard constraint: field types in Twenty cannot be changed after records are written to that field.

  • Fame Service API access is plan-dependent — not all tiers expose a full export endpoint

    Fame Service does not consistently expose a complete REST or GraphQL API across all plan tiers. Some setups offer only a filtered data export through the UI, which may not include all objects, custom fields, or historical activity records. If the API endpoint is not available, FlitStack falls back to CSV export, which introduces column-limit risks for records with many custom properties. We audit the API surface in Phase 1 and flag any object that cannot be reached programmatically — the migration plan documents the fallback path for each affected object before data movement begins.

  • Workflow and automation rules do not carry over and require manual rebuild in Twenty

    Fame Service stores workflow logic as platform-native rules that execute within its own runtime. These rules cannot be exported as migration data — they are business logic, not records. Twenty's workflow builder on Pro and Organization tiers provides a different automation model built around triggers, actions, and conditions. We export Fame Service workflow definitions as a structured JSON document listing each rule's trigger, conditions, and actions so your admin can rebuild them step-by-step. Sequences and email cadences require a third-party sales engagement tool connected via Twenty's API, as Twenty does not include native sequencing.

  • Large Fame Service datasets exceed Twenty's 20,000-record CSV export cap

    Twenty CRM's CSV export limits each file to 20,000 records — this is a Twenty-side constraint when using the built-in export. For Fame Service datasets above this threshold, FlitStack implements multi-file export sequencing with record-type ordering (Companies first, then People, then Opportunities) and a relation manifest that tracks which records were exported in which batch. The relation manifest ensures that foreign keys resolve correctly when records from different batches are imported into Twenty. If Fame Service uses API pagination limits as well, both constraints are reconciled in the sequencing plan.

  • Fame Service lifecycle and lead-stage data must be manually audited for consistency before mapping

    Fame Service implementations vary in how lifecycle stages and lead-status values are populated — some records may have null values, others may use inconsistent capitalization or custom status names not reflected in the standard pick-list. Twenty's custom select fields require explicit option values. FlitStack runs a pre-migration data audit that reports the full distribution of status values across Fame Service records, flags null rates, and identifies any non-standard values. The admin approves the value-mapping table before migration runs, ensuring that every status value in Fame Service has a corresponding option in Twenty's custom field.

Migration approach

Six steps for a successful Fame Service to Twenty CRM data migration

  1. Audit Fame Service data model and export all objects

    FlitStack AI connects to Fame Service via API (or CSV export if API is plan-limited) and inventories every object: People, Companies, Opportunities, Tasks, Notes, Attachments, and any custom objects. The audit captures object counts, custom field names and types, pick-list values, and owner distribution. We also identify objects inaccessible via API — those get flagged with a fallback export plan. The output is a data inventory document used to build the field-mapping table and the Twenty Data Model setup checklist.

  2. Set up Twenty CRM schema before data lands

    Before records move, your Twenty admin (or our team) creates all custom fields on People, Companies, and Opportunities in Settings → Data Model. This includes pick-list option sets for any stage fields, custom select fields for lifecycle or lead status, and any custom objects referenced in the migration plan. Twenty requires fields to exist before import — this step is sequenced first. We deliver a field-creation checklist specifying field type, label, and any required or unique flags for each custom field.

  3. Resolve owners by email match against Twenty workspace members

    Fame Service owner IDs on People, Companies, and Opportunities are matched to Twenty workspace members by email address. Unresolved owners are flagged in a pre-migration report — the team either invites the user to Twenty first or assigns their records to a designated fallback owner. No record lands in Twenty without a confirmed owner assignment. This step prevents orphaned records where the assigned-to field references a non-existent workspace member.

  4. Run a sample migration with field-level diff

    A representative slice — typically 100–500 records spanning People, Companies, Opportunities, and a sample of activity Tasks — migrates into Twenty first. FlitStack generates a field-level diff between the Fame Service source record and the Twenty destination record for every field in the mapping table. You review the diff to verify lifecycle-stage mapping, pipeline-to-stage mapping, owner resolution, and custom-field population. Approval of the sample diff triggers the full migration run.

  5. Execute full migration with delta-pickup window

    The full migration runs against Twenty CRM's import API. A delta-pickup window — typically 24–48 hours after the main run completes — captures any records created or modified in Fame Service during the cutover period so Twenty reflects the final state at go-live. The audit log records every operation (insert, update, skip) for reconciliation. One-click rollback is available if the field-level diff post-migration reveals data integrity issues requiring a restart.

Strengths

  • AGPL-3.0 open-source license with full source code on GitHub — no vendor lock-in, no sunset risk.
  • Unlimited users and unlimited custom objects on self-hosted, with no feature gating based on headcount.
  • REST and GraphQL APIs available on all paid tiers, not locked behind an enterprise add-on fee.
  • MCP server and webhooks shipped as standard features, not premium upgrades.
  • Modern PostgreSQL-backed data model that developer teams can query, extend, and self-host.

Weaknesses

  • Recent v1.0 release means limited production hardening compared to CRMs with multi-year operational track records.
  • No native email sequencing or sales engagement tools — follow-up cadences require a separate platform.
  • No native two-way email sync or inbox integration, requiring third-party connectors for full activity logging.
  • Self-hosting 'free' pricing hides real infrastructure and DevOps costs that stack up over time.
  • Workflow automation is functional but lacks the complexity needed for sophisticated multi-step sales motions.
