Overview
CosmoLex organizes legal practices around Clients, Matters, Contacts, Billing, and Trust Accounting — a data model designed for law firm compliance and invoicing. HubSpot uses a CRM graph of Contacts, Companies, Deals, and Engagements optimized for revenue lifecycle tracking. The two platforms share basic record types (people, organizations, financial items) but diverge sharply on legal-specific concepts: CosmoLex Matters have no direct HubSpot equivalent — we map them to HubSpot Deals so each matter becomes a pipeline record with stage, amount, and close date. CosmoLex Client records map to HubSpot Companies, and CosmoLex Contacts map to HubSpot Contacts with a link to the parent Company. We preserve original creation timestamps, matter numbers, and activity history (notes, tasks) as HubSpot engagements. Trust account balances, billing ledgers, and invoice history cannot map to HubSpot — those require separate legal accounting software or manual export. We run the migration via CosmoLex's export tools and HubSpot's bulk import API, sequencing records so foreign keys resolve correctly (Companies before Contacts before Deals). A delta-pickup window captures any records modified during cutover. The hardest planning step is mapping CosmoLex matter statuses to HubSpot pipeline stages — we deliver a stage-mapping plan before the first test run so your team can configure HubSpot pipelines to mirror your matter lifecycle.
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 CosmoLex object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
CosmoLex
Client
HubSpot
Company
1:1CosmoLex Client records map to HubSpot Companies. The firm name becomes Company Name, address data maps to street/city/state/zip properties, and phone maps to the primary phone property. Multi-office clients create multiple Company records linked by a parent-company custom property.
CosmoLex
Contact
HubSpot
Contact
1:1CosmoLex Contact records map to HubSpot Contacts 1:1. First name, last name, email, phone, and job title transfer directly. Each Contact is linked to its parent Company (from the CosmoLex Client). Unassigned contacts receive a default placeholder Company record.
CosmoLex
Matter
HubSpot
Deal
1:1CosmoLex Matters map to HubSpot Deals — each legal matter becomes a Deal record in HubSpot's pipeline. Matter name becomes Deal name, matter number is stored as a custom property (Matter_Number__c), and matter status (Active, Closed, Pending) maps to HubSpot pipeline stage values. We deliver a stage-mapping plan before migration so you can configure HubSpot pipeline stages to mirror your matter lifecycle.
CosmoLex
Matter Staff / Responsible Attorney
HubSpot
Deal Owner
1:1The CosmoLex responsible attorney and matter staff map to HubSpot Deal Owner by resolving the attorney's email against HubSpot user accounts. Unmatched attorneys are flagged for your HubSpot admin to assign a fallback owner or invite the user to HubSpot before the full migration runs.
CosmoLex
Matter Type / Practice Area
HubSpot
Custom Property on Deal
1:1CosmoLex matter types (e.g., Family Law, Personal Injury, Corporate) have no native HubSpot equivalent. We create a Matter_Type__c custom pick-list property on Deals and map each CosmoLex matter type to the corresponding HubSpot pick-list value. You configure the pick-list options in HubSpot during setup.
CosmoLex
Contact-Matter Association
HubSpot
Deal Contact Role
many:1CosmoLex allows multiple contacts per matter with roles (Attorney, Paralegal, Client, Opposing Counsel). HubSpot Deal Contact Roles handle most role mappings (Attorney maps to Decision Maker, Client maps to Business User). Custom roles outside the standard set are preserved as a custom multi-select property on the Deal.
CosmoLex
Time Entry / Billable Hours
HubSpot
Custom Property on Deal + Activity Notes
1:1CosmoLex time entries do not map cleanly to HubSpot. We export time entries as a CSV with matter reference and attach them as a linked file on the HubSpot Deal record. Total billable hours are summarized in a custom Number field (Total_Billable_Hours__c) on the Deal for reporting purposes.
CosmoLex
Invoice / Billing Record
HubSpot
No Equivalent
1:1CosmoLex invoice and billing records have no HubSpot equivalent — HubSpot does not handle legal invoicing or trust accounting. We export invoices as a CSV linked to the corresponding Deal record. For financial reporting, your firm will need to maintain CosmoLex billing data separately or export final invoices before decommissioning.
CosmoLex
Trust Account / IOLTA Balance
HubSpot
No Equivalent
1:1CosmoLex trust account balances and IOLTA records cannot transfer to HubSpot. HubSpot has no trust accounting module. We recommend exporting trust account data as a separate financial report from CosmoLex before migration and maintaining those records in a dedicated legal accounting tool going forward.
CosmoLex
Document / File
HubSpot
HubSpot Files
1:1CosmoLex documents attached to matters are downloaded and re-uploaded to HubSpot Files associated with the corresponding Deal. File size limits apply (HubSpot default 25MB per file). Documents are linked by matter number so the file context is preserved in HubSpot's file manager.
CosmoLex
Matter Notes
HubSpot
Engagement Note
1:1CosmoLex matter notes migrate as HubSpot Engagement Notes on the corresponding Deal record. Original timestamps and author information are preserved. Rich-text formatting is retained where the note format supports it.
CosmoLex
Custom Fields (Client/Matter/Contact)
HubSpot
Custom Properties
1:1Any CosmoLex custom fields on Client, Matter, or Contact records are recreated as HubSpot custom properties on the equivalent object (Company, Deal, Contact). We deliver a custom-field creation plan as part of the migration package so your HubSpot admin can pre-configure the schema before data lands.

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.
CosmoLex gotchas
Financial migration is balances-forward only, not historical
Two-phase migration sequencing is mandatory
Hard costs must be imported as soft costs
No public API for automated bulk export
Chart of Accounts is user-setup after import, not migrated
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Extract CosmoLex data using export tools
FlitStack initiates a data extraction from CosmoLex using the platform's export tools. We pull Client records, Contact records, Matter records, contact-matter associations, matter notes, and document file references. For financial data (invoices, time entries, trust balances), we export as structured CSVs linked by matter number. We validate the export completeness against your firm's matter count before proceeding to mapping.
Configure HubSpot pipelines and custom properties
Before data lands, your HubSpot admin (guided by our setup plan) creates the pipelines and custom properties needed for the migration. We deliver a pipeline-stage mapping document that translates CosmoLex matter statuses to HubSpot stage names. Custom properties (Matter_Number__c, Matter_Type__c, Total_Billable_Hours__c, Source_Record_ID__c) are created on the Deal object, and Contact Role pick-list values are configured to match your firm's role names.
Run sample migration with field-level diff
A representative slice of records migrates first — typically 50–200 records spanning the full object graph: a sample of Clients, their associated Contacts, and Matters with notes and document references. We generate a field-level diff report comparing source values against destination values so you can verify matter number preservation, stage mapping, owner resolution, and custom property population before the full run commits.
Execute full migration with delta-pickup window
The full dataset migrates in sequenced batches: Companies first (Client records), then Contacts with Company associations, then Deals with owner resolution and stage mapping. A delta-pickup window (typically 24–48 hours) captures any records created or modified in CosmoLex during the cutover period. Documents are downloaded from CosmoLex and re-uploaded to HubSpot Files associated with the parent Deal. An audit log records every operation, and one-click rollback is available if reconciliation identifies data integrity issues.
