Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Effort

What's pushing teams away

  • Support responsiveness is a recurring complaint — multiple Capterra reviewers report delayed responses from the Effort support team, with one citing that support needed to be more proactive.
  • Training is described as poor and insufficient — users report the platform has too many features and lacks guided customization, leaving teams to figure out configuration on their own.
  • iOS compatibility issues surface in G2 reviews as a concrete friction point, with field workers on Apple devices experiencing performance problems that hinder daily use.
  • Feature complexity without customization guidance leads teams to feel overwhelmed — one reviewer specifically noted the platform needs to tailor its features to each customer's specific needs rather than presenting everything at once.

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 Effort objects map to Twenty CRM

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

maps to

Twenty CRM

People

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Companies

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Opportunity

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Task / Note

1:1
Fully supported

Effort'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)

maps to

Twenty CRM

Custom Field

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Custom Object

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Workspace Member

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Attachment

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Relation / Custom Field

1:1
Fully supported

Effort 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

maps to

Twenty CRM

Workflow (rebuild required)

1:1
Fully supported

Effort 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.

Pair-specific challenges

  • Effort's multiple deal pipelines require flattening into Twenty's single Opportunities view

    Effort supports multiple concurrent deal pipelines with independently named stages per pipeline — a common configuration for teams segmenting deals by product line, region, or sales team. Twenty CRM uses a single Opportunities object with one stage pick-list. Migrating Effort's multi-pipeline setup to Twenty means your team loses the ability to view multiple pipeline boards side by side. We handle this by mapping each Effort pipeline to a custom Pipeline__c text field on the Opportunity record, preserving which pipeline the deal originated in. Stage values are mapped individually per pipeline using a value-mapping table, so the historical stage name and order are preserved even though they now live in a single Opportunities list.

  • Twenty requires custom fields to exist before CSV import — they are not auto-created

    Twenty's CSV import process writes data into existing fields only; it does not generate new fields from the CSV column headers. Effort's custom fields must be pre-created in Twenty's Settings → Data Model with the correct field type (text, number, select, date, relation) before the migration import runs. If a custom field is missing in Twenty, its values are dropped silently during import. FlitStack delivers a pre-migration checklist naming every custom field that must be created in Twenty, the field type to use, and any pick-list options to configure — so your workspace is ready before data lands. This step is the most common source of data loss in DIY Effort-to-Twenty migrations.

  • Effort's N:N contact-to-company associations collapse to one primary companyId in Twenty

    Effort allows a contact to be associated with multiple companies simultaneously — a common pattern for sales reps who manage relationships across a holding company and its subsidiaries. Twenty CRM's People record has a single companyId lookup field, with the ability to add secondary company relations through a custom relation object. When a contact in Effort has more than one associated company, FlitStack migrates the most recently modified company as the primary companyId and surfaces the others in a custom Secondary_Companies__c field for your admin to resolve post-migration. If your reporting depends on multi-company contact views, plan for a custom relation setup before go-live.

  • Effort sequences and automation rules have no export path — rebuild required in Twenty

    Effort sequences and workflow automation rules are stored as platform-specific configuration inside Effort's system and cannot be exported in a portable format. Twenty's workflow builder provides a different automation model with its own triggers, conditions, and actions. When you migrate to Twenty, your Effort sequences and automations must be rebuilt. FlitStack documents your existing Effort automation definitions — including trigger events, time delays, conditional branching, and action sequences — in a structured format that your Twenty admin or implementation partner can use as a rebuild specification. This documentation is delivered as part of the migration package, so the automation work is a planned effort rather than an improvised rebuild from memory.

  • Twenty does not yet have native outbound sequencing — plan for a third-party sequencing tool

    Reddit discussions on r/CRM and r/selfhosted confirm that Twenty's current workflow builder supports internal automations (task reminders, field updates, notification triggers) but lacks native outbound sequencing for sales cadences — the ability to automatically trigger a series of timed emails and calls based on prospect actions. If your sales process relies on Effort sequences for outreach, you will need to either build a custom automation in Twenty's workflow builder or adopt a third-party sequencing tool (such as a mail merge + task automation stack) to replicate that capability post-migration. FlitStack surfaces this gap in the migration plan and offers a rebuild consultation as an add-on service.

Migration approach

Six steps for a successful Effort to Twenty CRM data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Platform deep dives

Context on both ends of the pair

Effort logo

Effort

Source

Strengths

  • Per-user pricing model at $12/month is transparent and predictable for small teams.
  • Mobile-first field workflow tool combining attendance, location tracking, and daily reporting in one place.
  • Unlimited customizable forms without gating behind paid tiers.
  • Real-time data visibility for managers overseeing field teams.
  • DIY no-code configuration reduces reliance on external consultants.

Weaknesses

  • iOS performance issues documented in user reviews create friction for Apple-based field teams.
  • Support responsiveness lags, leaving customers without timely help when configuration issues arise.
  • No native Companies or Accounts object means customer-level data requires custom mapping work.
  • No publicly documented bulk export or API endpoint makes data extraction a manual or developer-dependent process.
  • Training and onboarding materials are insufficient, leading to a steep self-service learning curve.

Destination

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.

Most Effort-to-Twenty migrations complete in 24–48 hours for under 50,000 records, depending on dataset complexity, API rate limits, and the number of custom fields requiring transformation. Larger setups with 500,000+ records, complex custom-object relationships, or significant schema divergence extend to 5–7 days. The longest planning step is creating Twenty custom fields in Settings → Data Model and resolving Workspace Members before the import runs — those steps must complete before data can land cleanly in Twenty.
