Overview
Assembly Neos is a legal practice management platform built around matters, parties, billable time, and court-document workflows. Twenty CRM is a general-purpose open-source CRM with People, Companies, Opportunities, Tasks, and Notes objects plus a GraphQL/REST API for import. The migration carries over every standard record type — contacts, clients (as companies), matters (as opportunities), activities, billable time, and all custom properties — mapping legal-specific fields like practice area, case status, and billing rate into Twenty's custom-field model. Workflows, document templates, email templates, integrations (Microsoft 365, DocuSign, QuickBooks, RingCentral), and the billing model have no direct Twenty equivalent and must be rebuilt or reconnected manually after cutover. FlitStack AI sequences the migration so parent objects load before their children, runs a sample migration with field-level diff before committing, and captures any in-flight changes during a 24–48h delta-pickup window using Assembly Neos's scoped read access. Data integrity is maintained through a structured migration plan that addresses record dependencies, custom field pre-creation in Settings → Data Model, and phased imports that handle Twenty's 20,000-record CSV export limit. The scoped read access approach means your team continues working in Assembly Neos throughout the migration without disruption.
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 Assembly Neos 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.
Assembly Neos
Contact / Party
Twenty CRM
People
1:1Assembly Neos contact records (attorneys, paralegals, opposing counsel, clients) map 1:1 to Twenty CRM People records. Email address is the unique identifier in Twenty — used for deduplication and user resolution during migration. Contacts without an email address receive a placeholder email and are flagged for manual review.
Assembly Neos
Client / Firm
Twenty CRM
Company
1:1Assembly Neos client firm records map to Twenty CRM Companies. Firm name becomes Company.displayName. Domain maps to Company.website. For contacts with no primary client firm, a default 'Individual' company record is created in Twenty and the contact's companyId points there.
Assembly Neos
Matter / Case
Twenty CRM
Opportunity
1:1Assembly Neos matters map to Twenty CRM Opportunities — the closest equivalent object in Twenty's schema. Matter number is preserved as a custom Opportunity field (Matter_Number__c). Case status (Open, Pending, Closed) maps to a custom StageName pick-list that must be pre-created in Twenty Settings → Data Model before the import runs.
Assembly Neos
Activity (Call, Email, Meeting)
Twenty CRM
Task / Event
1:1Assembly Neos activities with type 'Call' or 'Email' migrate as Twenty CRM Tasks with Task.type set accordingly. Meeting activities migrate as Twenty Events with original start/end timestamps preserved. The activity description maps to Task.body or Event.body. Activity owner resolves by email to a Twenty workspaceMember.
Assembly Neos
Activity Note / Memo
Twenty CRM
Note
1:1Free-form notes logged against a matter in Assembly Neos migrate as Twenty CRM Notes attached to the corresponding Opportunity record. The note title becomes Note.title; the body maps to Note.body. Rich-text formatting in Assembly notes is flattened to plain text during migration.
Assembly Neos
Billable Time Entry
Twenty CRM
Custom BillableTime Object
1:1Assembly Neos billable time records (hours, rate, amount, work date) have no native equivalent in Twenty CRM. FlitStack creates a custom BillableTime object in Twenty with fields for hours (number), rate (currency), total amount (currency), work date (date), and description (text). The custom object is linked to the Opportunity via a relation field.
Assembly Neos
Document / Attachment
Twenty CRM
Files
1:1Assembly Neos document attachments are re-uploaded to Twenty CRM's Files feature. File name is preserved as a custom text field on the file (or as a Note attachment to the parent Opportunity). Large documents that exceed Twenty's file size limits are flagged for chunked upload. Inline images in Assembly notes are downloaded and rehosted.
Assembly Neos
Custom Property (Contact)
Twenty CRM
Custom Field on People
1:1Assembly Neos custom properties on contacts (e.g., bar_number, practice_areas) require pre-created custom fields in Twenty CRM under Settings → Data Model. All custom fields must exist before CSV import runs — the import creates records, not fields. Contact-type pick-lists in Assembly (Attorney, Paralegal, Client) map to a custom role pick-list field in Twenty.
Assembly Neos
Custom Property (Matter)
Twenty CRM
Custom Field on Opportunity
1:1Assembly Neos custom properties on matters (e.g., court_name, opposing_counsel, insurance_carrier) become custom fields on the Twenty CRM Opportunity. Pick-list values in Assembly map to Twenty pick-list options that must be pre-configured. Multi-select values in Assembly explode into multiple rows or a custom multi-select field type in Twenty.
Assembly Neos
Workflow / Automation
Twenty CRM
No equivalent
1:1Assembly Neos workflows, automations, and triggered actions have no direct equivalent in Twenty CRM's workflow engine. FlitStack exports your workflow definitions as a structured reference document for your Twenty admin to rebuild in Settings → Workflows. This is always a manual step — no automated translation is possible.
Assembly Neos
Document Template
Twenty CRM
No equivalent
1:1Assembly Neos document templates for letters, agreements, and court filings do not migrate to Twenty CRM. Twenty does not have a native document template engine. Templates must be exported as reference PDFs and rebuilt using your preferred document generation tool (e.g., DocuGen, Mailmerge) post-migration.
Assembly Neos
Integration (Microsoft 365, DocuSign, QuickBooks, RingCentral)
Twenty CRM
No equivalent — rebuild required
1:1Assembly Neos integrations with Microsoft 365 (Outlook, Teams), DocuSign, QuickBooks, and RingCentral have no direct mapping in Twenty CRM. Each integration requires manual reconfiguration in Twenty's Settings → Integrations section. QuickBooks data (if used for billing) should remain the accounting system of record and not be migrated into Twenty's custom BillableTime object.

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.
Assembly Neos gotchas
Built-in accounting removed requires QuickBooks Online
Per-user pricing model affects migration scope
Document export requires Premium or Pro tier for full OCR
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 and export Assembly Neos data
FlitStack connects to your Assembly Neos instance via scoped read access and exports all standard and custom record types: contacts, clients/firms, matters, billable time entries, activities, and documents. We run a data quality report to flag duplicate contacts, stale matters (no activity in 24+ months), and missing required fields. The audit output determines whether a full migration or a scoped migration (active matters only) is appropriate for your use case.
Create Twenty CRM schema and custom fields
Before any data loads, we deliver a schema setup plan based on your Assembly Neos custom property inventory. Your Twenty admin (or FlitStack) creates all custom fields in Settings → Data Model: Opportunity custom fields for matter status, practice area, opposing counsel, court name, and matter number; a custom BillableTime object with hours, rate, and amount fields; and a contact role pick-list on the People object. Fields must exist before the CSV import runs.
Resolve users and match contacts to companies
Twenty CRM requires workspace members to exist before user-referenced records can import. We invite all active Assembly Neos users to Twenty by email match, then resolve matter assigned attorneys to Opportunity accountOwnerId lookups. Contacts without a primary client firm are linked to a default 'Individual' Company record. All contacts receive a Source_System_ID__c value linking back to the Assembly Neos record for traceability.
Run sample migration with field-level diff
A representative slice of 50–200 records — spanning contacts, companies, matters, activities, and billable time entries — migrates first. We generate a field-level diff comparing source values to destination values for every mapped field. You review the diff to verify matter number preservation, case status mapping, practice area values, and owner resolution before the full run commits. This step catches missing custom fields, value-mapping gaps, and pick-list mismatches before data lands in Twenty.
Full migration with delta-pickup cutover
The full dataset migrates to Twenty CRM in dependency order: Companies first, then People (with companyId links), then Opportunities (with companyId and peopleId), then the custom BillableTime object, then Tasks and Notes. A 24–48 hour delta-pickup window captures any Assembly Neos records modified during the cutover window. Audit log records every insert, update, and link operation. One-click rollback is available if reconciliation reveals mapping errors. After cutover, your team begins rebuilding workflows and reconnecting integrations in Twenty.
