Overview
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.
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 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
Twenty CRM
People
1:1JARVIS 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
Twenty CRM
Opportunity
1:1JARVIS 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
Twenty CRM
Company
1:1JARVIS 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)
Twenty CRM
Task / Note
1:1JARVIS 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
Twenty CRM
Files
1:1JARVIS 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)
Twenty CRM
Custom Field on Opportunity
1:1JARVIS 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)
Twenty CRM
Custom Field on People
1:1JARVIS 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
Twenty CRM
Custom Field / Note on Opportunity
1:1JARVIS 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
Twenty CRM
Workspace Member
1:1JARVIS 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
Twenty CRM
No Equivalent
1:1JARVIS'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
Twenty CRM
Note / Custom Field on Opportunity
1:1JARVIS 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
Twenty CRM
Custom Field on Opportunity + Task
1:1JARVIS 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.

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.
Jarvis Legal gotchas
No native Excel or CSV export for reports or data
Bulk import of large billing histories fails silently
Custom field IDs are URL-encoded UUIDs requiring manual retrieval
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 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.
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.
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.
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.
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.
