Overview

What this migration involves

Jarvis Legal is a legal practice management platform built around matters, clients, documents, and billing—its data model centers on the Matter as the primary work unit, with contacts attached as clients, not the other way around. Twenty CRM is a general-purpose open-source CRM that uses People, Companies, and Opportunities as its core objects and has no native legal-matter construct. The fundamental migration challenge is collapsing Jarvis's matter-centric model into Twenty's opportunity-centric model: each Jarvis matter becomes a Twenty Opportunity, but the legal-specific attributes attached to the matter (court date, billing rate, responsible attorney, matter type, case stage) require custom fields on the Opportunity object. FlitStack AI extracts all Jarvis data via the Jarvis API, maps client records to Twenty People, company records to Twenty Companies, matters to Opportunities with the legal custom fields, and re-uploads attached documents to Twenty's file storage. Workflows, document automation rules, and billing templates from Jarvis Legal do not migrate—Twenty's workflow builder handles process automation differently, and these must be rebuilt manually. We sequence the migration so foreign-key relationships (companyId on People, companyId on Opportunities) resolve correctly: Companies first, then People, then Opportunities. A delta-pickup window captures any matter updates made in Jarvis during cutover.

Why teams make this switch

Two sides of the same decision

Leaving

Jarvis Legal

What's pushing teams away

  • Limited data export options — reviewers explicitly note inability to export data to Excel, which blocks firms needing to pull reports or migrate to other systems.
  • Established firms with decades of billing history encounter severe performance issues during migration; one firm reported the platform could not handle importing 20 years of legacy data.
  • Reporting capabilities are sparse beyond invoicing — firms needing statistical analysis, case analytics, or client demographic exports find the platform insufficient.
  • Mobile app stability issues during transition periods can disrupt firm operations; one reviewer reported two weeks of downtime during a switch.

Choosing

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 Jarvis Legal objects map to Twenty CRM

Each row shows how a Jarvis Legal 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.

Jarvis Legal

Contact / Client

maps to

Twenty CRM

People

1:1
Fully supported

JARVIS client records map directly to Twenty People. The JARVIS contact properties (name, email, phone, address) map to the standard Twenty People fields. A company link in JARVIS becomes the companyId relation in Twenty. All client-specific attributes including custom fields are carried over as custom fields on the People record during the migration process.

Jarvis Legal

Matter

maps to

Twenty CRM

Opportunity

1:1
Fully supported

JARVIS matter is the central legal work unit and becomes a Twenty Opportunity. The matter name maps to Opportunity.name, the matter stage/status maps to a custom Opportunity stage field, and all legal-specific attributes (case type, court, billing rate) become custom fields on the Opportunity.

Jarvis Legal

Company / Organization

maps to

Twenty CRM

Company

1:1
Fully supported

JARVIS organizations attached to matters or clients map to Twenty Companies. JARVIS allows multiple contacts per organization; we link the primary People record to the Company via companyId and surface secondary contacts as additional People records with the same companyId.

Jarvis Legal

Activity (Call, Meeting, Email)

maps to

Twenty CRM

Task / Note

1:1
Fully supported

JARVIS activities logged against a matter map to Twenty Tasks or Notes depending on type. Calls and meetings become Tasks with the original timestamp and owner preserved. Email records and matter notes become Twenty Notes attached to the relevant People or Opportunity record.

Jarvis Legal

Document / File Attachment

maps to

Twenty CRM

Files

1:1
Fully supported

JARVIS documents attached to matters are re-uploaded to Twenty's file storage and linked to the corresponding Opportunity record. File size limits and inline images in JARVIS notes are downloaded and rehosted in Twenty. The original upload date is preserved as a custom field.

Jarvis Legal

Custom Field (Matter-level)

maps to

Twenty CRM

Custom Field on Opportunity

1:1
Fully supported

JARVIS custom fields scoped to matters (court date, billing rate, matter type, responsible attorney, case reference number) require custom fields to be pre-created in Twenty's Settings → Data Model before the Opportunity import runs. These are created as the matching Twenty field type: date for court date, number for billing rate, select for matter type.

Jarvis Legal

Custom Field (Client-level)

maps to

Twenty CRM

Custom Field on People

1:1
Fully supported

JARVIS client-level custom fields such as client type, referral source, and bar number for attorneys map to custom fields on the Twenty People object. These must be created in Twenty before the People import step using the same field type and pick-list values as defined in JARVIS.

Jarvis Legal

Time Entry

maps to

Twenty CRM

Custom Field / Note on Opportunity

1:1
Fully supported

JARVIS time entries linked to a matter do not map to a native Twenty object. We migrate the total billable hours and total billing amount as custom number fields on the Opportunity record. Individual time entries are preserved as Notes with the attorney name, date, duration, and description.

Jarvis Legal

User / Owner

maps to

Twenty CRM

Workspace Member

1:1
Fully supported

JARVIS user accounts are resolved against Twenty Workspace Members by email match. All JARVIS records are flagged with the owner email before migration. Unmatched owners are flagged for your team to invite to Twenty before the migration run to ensure all ownership assignments resolve correctly.

Jarvis Legal

Trust Account

maps to

Twenty CRM

No Equivalent

1:1
Fully supported

JARVIS's trust accounting functionality (IOLTA-style client funds tracking) has no equivalent in Twenty CRM. Trust balance data is preserved as a Note on the relevant People or Opportunity record for reference, but the financial ledger cannot be migrated into Twenty's object model.

Jarvis Legal

Invoice

maps to

Twenty CRM

Note / Custom Field on Opportunity

1:1
Fully supported

JARVIS invoices tied to matters are not migrated as financial records. The invoice total and status are preserved as custom fields on the related Opportunity (Invoice_Total__c, Invoice_Status__c). Individual line items are preserved as Notes for reference and audit trail purposes.

Jarvis Legal

Calendar / Court Date

maps to

Twenty CRM

Custom Field on Opportunity + Task

1:1
Fully supported

JARVIS court calendaring entries attached to matters become Tasks in Twenty with the original date/time preserved. The next court date is also stored as a custom date field on the Opportunity so it surfaces in the Twenty Opportunity detail view.

Pair-specific challenges

  • JARVIS matter-stage model has no native equivalent in Twenty's Opportunity pipeline

    JARVIS tracks matter lifecycle through custom statuses and stages that are defined per-firm. Twenty CRM's Opportunities use a stage pick-list that is flat across all Opportunity records—Twenty does not have a matter-stage concept natively. JARVIS matter status values must be mapped to Twenty Opportunity stage values value-by-value, and any firm-specific matter phases that don't match Twenty's stage names need custom field creation. If your JARVIS setup uses more than three matter types (e.g., Litigation, Corporate, Family Law) each with their own status workflow, each matter type may require its own custom pick-list field rather than relying on the native stage field.

  • Twenty's strict import ordering requirement breaks if Companies are not migrated first

    Twenty's CSV import mechanism requires that the 'one' side of all relationships exist before importing the 'many' side. Specifically, Companies must be imported before People (which reference companyId), and both must exist before Opportunities are imported (which also reference companyId). JARVIS does not enforce this ordering—matters and contacts can be created simultaneously. FlitStack AI sequences the migration to resolve foreign-key dependencies before loading, but if your JARVIS data has People records with company references that have no matching JARVIS organization record, those contacts land as orphaned People in Twenty and must be manually linked post-migration.

  • JARVIS trust accounting and invoice ledger cannot be represented in Twenty's data model

    JARVIS Legal includes trust accounting (IOLTA-style client fund tracking) and a full invoice generation system tied to matter records. Twenty CRM has no native accounting, billing, or trust accounting objects. The invoice total and status can be preserved as custom fields on the Opportunity, but the full invoice line-item history, trust balance, and payment records do not map to any Twenty object. These records must be preserved in a PDF export from JARVIS or migrated to a dedicated accounting tool. FlitStack AI will flag all JARVIS financial records during the data audit and confirm which records can be preserved as Notes versus which must be exported separately.

  • Twenty's 20,000-record CSV export limit can split JARVIS matter exports

    Twenty's export function is capped at 20,000 records per export operation. Most JARVIS Legal instances for small-to-mid firms fall below this threshold, but firms with high matter counts or extensive activity histories may need multiple export passes. The 100 requests/minute API rate limit on Twenty's Pro plan also constrains automated migration throughput—large document re-uploads may require batched processing. FlitStack AI will scope the record count during discovery and confirm whether multiple export passes or extended runtime are needed before the migration begins.

  • JARVIS document version history collapses to latest version in Twenty file storage

    JARVIS Legal tracks document version history for matters—each revision of a contract or filing is stored separately. Twenty's file storage model supports one file attachment per record without native version tracking. FlitStack AI migrates the latest version of each document and stores the complete version history as a custom Note attached to the document record, listing the version number and date for each revision. If your practice relies on accessing prior document versions directly from the CRM record, this representation requires a workflow adjustment in Twenty.

Migration approach

Six steps for a successful Jarvis Legal to Twenty CRM data migration

  1. Audit JARVIS data and plan Twenty workspace schema

    FlitStack AI connects to the JARVIS API to enumerate all contacts, companies, matters, activities, time entries, and custom fields in your workspace. We generate a JARVIS data audit report listing record counts per object, all custom field names and types, and attachment volumes. From this, we produce a Twenty workspace setup plan: the list of custom fields to create in Settings → Data Model, the import order, and the mapping document that shows every JARVIS field and its Twenty destination. Your JARVIS admin reviews and approves the plan before we create any fields or touch any data.

  2. Create custom fields in Twenty and invite team members

    Following the approved schema plan, FlitStack AI creates all required custom fields on the People, Company, and Opportunity objects in your Twenty workspace via the Twenty API. Custom select fields are populated with the exact pick-list values from JARVIS. We also invite all JARVIS users to Twenty by email before the import begins, because any Opportunity or People record with an owner reference must resolve to an existing Twenty Workspace Member—unresolved owners cause import errors in Twenty.

  3. Export JARVIS data and run sample migration with field-level diff

    We extract all JARVIS records via the JARVIS REST API: Companies first, then People, then Matters, then Activities and Time Entries. A sample migration runs against a staging slice of 100–500 records spanning all object types. We generate a field-level diff report showing every mapped field value from JARVIS alongside its Twenty equivalent, so you can verify that matter types, billing rates, court dates, and attorney assignments landed correctly before the full run commits.

  4. Execute full migration with delta-pickup window

    The full migration loads all JARVIS records into Twenty in the correct sequence: Companies → People → Opportunities → Tasks/Notes. JARVIS documents are downloaded and re-uploaded to Twenty's file storage linked to the relevant Opportunity. After the initial load completes, a delta-pickup window (typically 24–48 hours) captures any matters, contacts, or activities modified or created in JARVIS during the cutover. FlitStack AI runs the delta delta against the JARVIS API and applies only the changed records to Twenty.

  5. Audit log, validation report, and rollback plan

    Every migration operation is recorded in an audit log showing source record ID, destination record ID, field mappings applied, and timestamp. We generate a post-migration validation report comparing JARVIS record counts and field totals against Twenty record counts to confirm nothing was dropped. If reconciliation reveals discrepancies, FlitStack AI executes a one-click rollback that removes all migrated records from Twenty and restores the source data in JARVIS. Your team can then investigate the discrepancy and re-run when ready.
