Overview

What this migration involves

LEAP and Twenty CRM take different approaches to organizing customer data. LEAP structures its core around clients and matters with associated documents, contacts, and billing entries. Twenty CRM normalizes this into People (contacts), Companies (organizations), and Opportunities (deals), with a fully customizable data model accessible through Settings → Data Model. FlitStack AI extracts LEAP data via its REST API — pulling contacts, companies, deal records, activities, and custom field values — then transforms and loads them into Twenty using the CSV import workflow (up to 20,000 records per file) or direct API inserts for larger volumes. The migration preserves original create dates as custom datetime fields in Twenty since Twenty's native CreatedAt timestamp reflects the import moment, not the source creation date. Owner resolution happens by email match against Twenty workspace members; unmatched owners surface as a pre-flight flag so your team can invite users or assign fallbacks before records land. Workflows, sequences, and any LEAP automation logic do not migrate — those are destination-side configuration work that requires manual rebuild in Twenty's workflow builder. Activities (calls, emails, meetings, notes) migrate as Twenty Tasks and Notes with original timestamps and owner links intact.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

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

LEAP

What's pushing teams away

  • Performance has degraded after recent platform updates, with the software crashing and causing instability in Outlook and Office integrations, which disrupts daily practice operations.
  • Support responsiveness does not match the promised service level — customers report generic email responses and unwillingness to revert problematic updates or provide hands-on migration assistance.
  • The transition service is marketed as supported but relies heavily on firm-side data preparation, and LEAP's policy of migrating from only a single source system creates risk for firms running hybrid environments.
  • Setup and IT onboarding coordination is poor — anti-virus exception requirements are not communicated upfront, leading to machine freezes and slow performance that go unaddressed during the implementation period.

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 LEAP objects map to Twenty CRM

Each row shows how a LEAP 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.

LEAP

Contact

maps to

Twenty CRM

People

1:1
Fully supported

LEAP contact records map directly to Twenty People objects. Each contact's primary client/matter link becomes a relation field pointing to the mapped Company record. Multi-contact matters where multiple contacts share one client require a Company record to exist first so the contact-company foreign key resolves correctly during import.

LEAP

Client / Account

maps to

Twenty CRM

Company

1:1
Fully supported

LEAP client records become Twenty Companies. The client name maps to Company name, and LEAP client type or industry classification maps to a custom select field on the Company if Twenty's default industry list does not cover your classification. Parent-child client hierarchies translate to a Company relation field pointing to the parent Company record.

LEAP

Matter / Deal

maps to

Twenty CRM

Opportunity

1:1
Fully supported

LEAP matter records map to Twenty Opportunities since both represent deal or case tracking. Matter name becomes Opportunity name, and the matter description or summary field becomes the Opportunity description. LEAP matter status values map to Opportunity stage values via value-by-value correspondence defined in the migration plan before import.

LEAP

Matter Stage / Status

maps to

Twenty CRM

Opportunity Stage

1:1
Fully supported

LEAP matter stage values (e.g., Intake, In Progress, Pending Review, Closed) map one-to-one to Twenty Opportunity stage pick-list values. Each LEAP stage gets a corresponding stage in Twenty's Data Model stage definition. Stage-entered timestamps from LEAP preserve as custom datetime fields on the Opportunity since Twenty does not natively track stage transition timestamps.

LEAP

Billable Hours / Time Entry

maps to

Twenty CRM

Custom Object (TimeEntry)

1:1
Fully supported

LEAP time entries do not have a native equivalent in Twenty's standard model. We create a TimeEntry custom object in Twenty with fields for date, duration, description, linked Person, and linked Opportunity. This preserves billable hour history for reporting continuity, though the rebuild of billing workflows in Twenty falls outside migration scope.

LEAP

Document / File Attachment

maps to

Twenty CRM

Note / Attachment relation

1:1
Fully supported

LEAP documents associated with matters are exported as files and re-hosted as Twenty Notes with file attachments. The note body captures the document description from LEAP, and the file attachment re-upload uses Twenty's file storage. Large document volumes may require batched import to stay within per-file size limits.

LEAP

Email / Call / Meeting Activity

maps to

Twenty CRM

Task

1:1
Fully supported

LEAP activities logged against matters (calls, emails, meetings) map to Twenty Tasks attached to the related People or Opportunity record. Original activity timestamps, type (call, email, meeting), and owner email are preserved as Task fields. Activity type becomes a Task custom select field since Twenty Tasks do not natively distinguish call versus email subtypes.

LEAP

Custom Field (per object)

maps to

Twenty CRM

Custom Field (same object)

1:1
Fully supported

LEAP custom fields created per contact, client, or matter require pre-creation in Twenty's Settings > Data Model before the migration CSV loads. We deliver a custom field manifest listing each LEAP custom field, its data type, and the Twenty field type that best fits (text, number, select, multi-select, date, etc.). Fields must exist in Twenty first — the CSV import creates records, not schema.

LEAP

LEAP User / Staff

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

LEAP user and staff records map to Twenty Workspace Members. Owner assignment on migrated records resolves by email match — the LEAP user email must correspond to an accepted Twenty workspace invitation. Unmatched users surface as a pre-flight flag so your team can invite them before the migration commits.

LEAP

Trust / Billing Entry

maps to

Twenty CRM

Custom Object (TrustEntry)

1:1
Fully supported

LEAP's trust accounting records do not map to standard Twenty objects. We create a TrustEntry custom object with fields for transaction type, amount, date, client relation, and description. This preserves the trust ledger history for compliance and audit purposes. Trust workflow rules require manual configuration in Twenty.

Pair-specific challenges

  • Fields must pre-exist in Twenty before CSV import

    Twenty's CSV import creates records, not schema. Every LEAP custom field needs a corresponding custom field created in Twenty's Settings > Data Model before any data loads. If a field is missing, the import skips those records silently or throws an error on that column. FlitStack delivers a custom field manifest listing every LEAP custom property, its data type, and the recommended Twenty field type so your admin can pre-build the schema before the migration window opens.

  • Import order is mandatory — Companies before People before Opportunities

    Twenty enforces foreign key integrity during import. The Company record must exist before a Person can reference companyId, and both must exist before an Opportunity can reference personId or companyId. If you import in the wrong order, Twenty rejects the dependent records. FlitStack sequences the migration as a three-pass process: Companies first, then People with their companyId links, then Opportunities with their relation links — with a pre-flight dependency graph generated before any CSV file is submitted to Twenty.

  • Original create dates do not map to Twenty's native CreatedAt

    Twenty's CreatedAt timestamp is set at record creation time in Twenty — it does not accept a retroactive create date via CSV import or standard API insert. All historical creation timestamps from LEAP must be stored as a custom datetime field (e.g., Original_Create_Date__c) on each object. Your reporting queries need to reference that custom field instead of Twenty's native timestamp to maintain historical continuity in deal aging and contact tenure reports.

  • Workflows and matter lifecycle automations do not transfer

    LEAP workflows tied to matter stages (e.g., automatic document generation, client notification triggers, billing workflow routing) are configuration constructs with no equivalent in Twenty's workflow engine. Twenty's workflow builder uses its own trigger-action model scoped to its People, Companies, and Opportunities objects. FlitStack exports your LEAP workflow definitions as a structured JSON document so your Twenty admin can rebuild the logic manually in Settings > Workflows. Budget 1–3 weeks for workflow rebuild depending on complexity.

  • Trust and billing accounting records require a custom object

    LEAP's trust accounting module — with its trust bank accounts, receipts, journals, and reconciliation records — has no standard equivalent in Twenty. We create a TrustEntry custom object in Twenty's Data Model to store transaction type, amount, date, client relation, and description. However, the trust accounting workflows themselves (disbursement rules, client ledger reconciliation) must be reconfigured manually in Twenty or through its API once the custom object schema is in place.

Migration approach

Six steps for a successful LEAP to Twenty CRM data migration

  1. Audit LEAP data and build the mapping document

    FlitStack connects to your LEAP instance via the LEAP API (leap.build) and exports all object records: contacts, clients, matters, activities, time entries, and custom field values. We generate a mapping document listing every source object, every target Twenty object, and every field-level correspondence — including custom field type conversions, value-mapping tables for pick-list fields, and notes on which LEAP fields have no Twenty equivalent and will be stored as custom reference fields.

  2. Prepare the Twenty workspace schema

    Before data lands, your admin creates the custom fields, custom objects (TimeEntry, TrustEntry), and workspace members in Twenty's Settings > Data Model. FlitStack delivers a schema setup checklist so nothing is missed. Workspace members must accept their invitations and appear in the Members list — owner resolution during migration requires an existing Twenty user record to match against. We recommend completing this step at least 48 hours before the migration window opens.

  3. Run a test migration with field-level diff

    A representative sample — typically 200–500 records spanning contacts, companies, opportunities, and a cross-section of custom fields — migrates first. We generate a field-level diff showing source value versus destination value for every mapped field, plus a count of unmatched owner emails, unresolvable parent-company links, and any records that failed to import due to schema mismatches. You review the diff, we adjust the mapping, and the process repeats until the test pass meets your acceptance criteria.

  4. Execute full migration with delta-pickup window

    The full dataset migrates in three ordered passes: Companies (pass 1), then People with companyId links (pass 2), then Opportunities and Activities with their relations (pass 3). A 24–48 hour delta-pickup window opens at cutover and captures any records created or modified in LEAP during the migration run. FlitStack generates a migration audit log listing every record touched, every transformation applied, and every owner email resolved. One-click rollback reverts all destination records if reconciliation fails.

  5. Reconcile, verify, and hand off the workflow rebuild brief

    We deliver a reconciliation report comparing LEAP record counts by object against Twenty record counts, flagging any gaps above the acceptance threshold (typically 0.5%). The workflow export JSON — containing your LEAP workflow definitions organized by trigger type and action chain — is handed off with a rebuild guide mapped to Twenty's workflow builder. Post-migration support is available for 10 business days following go-live to address any data issues discovered during team onboarding.

Platform deep dives

Context on both ends of the pair

LEAP logo

LEAP

Source

Strengths

  • All-in-one platform combining practice management, document automation, and financial compliance without third-party integration overhead.
  • Built-in trust accounting with General Ledger, nominal ledger, and purchase ledger disbursements covering jurisdiction-specific compliance requirements.
  • AI-assisted document creation embedded directly in the matter workflow reduces manual drafting time for standardised legal documents.
  • Over 5,140 documented electronic data conversions and 66,000+ global users provide evidence of a mature migration and support ecosystem.
  • 99.9% average uptime globally and cloud-native architecture eliminate on-premise server maintenance for law firms.

Weaknesses

  • No native bulk document export — LEAP caps batch exports at 100 documents per operation with no zip compression, requiring manual folder batching for large matters.
  • LEAP's single-datafile architecture enforces migration from one source system only, blocking firms that run multiple integrated practice management products from consolidating in a single transition.
  • No publicly documented API rate limits, making capacity planning for large data migrations an uncertainty that requires direct inquiry with LEAP's development team.
  • Custom Fields require schema extraction before migration begins, adding a preparatory step that is not always communicated during the initial scoping conversation.

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 LEAP-to-Twenty CRM migrations complete in 48–72 hours of clock time for setups under 50,000 total records across contacts, clients, matters, and activities. Firms with 500,000+ records or extensive trust accounting history extend to 5–7 days. The longest single step is preparing the Twenty workspace schema (creating custom fields and inviting members) before data begins moving — we recommend completing that 48 hours before the migration run starts.
