Overview
Moving from LeadMaster to Twenty CRM is a structural migration for small-to-mid-market teams leaving an aging SMB platform for a modern open-source alternative. LeadMaster stores company data as Accounts, leads as Leads, and pipeline deals as Opportunities tied to Accounts. Twenty CRM mirrors this model with Company, Person, and Custom opportunities but lacks a native Lead-to-Opportunity conversion action, meaning we split the migration into distinct phases and document the manual conversion step. We preserve owner assignments, custom form field data, case histories, and email send records; we do not migrate LeadMaster's point-and-click workflows or marketing automation sequences because they have no export mechanism. The migration uses Twenty's REST and GraphQL APIs with bulk chunking for large record volumes and delivers a written automation inventory for the customer's admin to rebuild post-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 LeadMaster 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.
LeadMaster
Account
Twenty CRM
Company
1:1LeadMaster Accounts (primary company/organization records) map directly to Twenty CRM Company records. The primary contact link migrates as a Person-Company relation. All standard address fields, custom properties, and the original LeadMaster account owner assignment preserve. We resolve the owner by email match against Twenty workspace members at migration time.
LeadMaster
Lead
Twenty CRM
Person
1:1LeadMaster Leads are the core object of the source data model. We map them 1:1 to Twenty Person records. The lead status, source, lifecycle fields, and owner assignment all transfer. Note that Twenty CRM has no native Lead-to-Opportunity conversion feature (as documented in GitHub issue #10422); we flag this gap during discovery and document the manual conversion step or custom automation needed post-migration to move Person records into Opportunity pipeline stages.
LeadMaster
Opportunity
Twenty CRM
Opportunity
1:1LeadMaster Opportunities map to Twenty CRM Opportunity records. Stage, amount, close date, owner, and associated Account (Company) link transfer. Custom pipeline stages from LeadMaster are mapped against Twenty's stage list during import. The Opportunity-Company and Opportunity-Person relationships resolve at migration time using company domain or contact email as the lookup key.
LeadMaster
Case
Twenty CRM
Custom Object (Case)
1:1LeadMaster Cases (customer support/helpline module) map to a Twenty CRM custom object named Case. We pre-create the Case object and its fields via Twenty's /metadata API before migration: case number, status, priority, description, and the associated company/person link. Conversation threads migrate as Task or Note records attached to the Case.
LeadMaster
Custom Form
Twenty CRM
Custom Object + Fields
lossyLeadMaster's custom form builder stores field definitions separately from submitted response data. We extract both during export. Custom form fields that have no direct equivalent in Twenty's schema are pre-created as custom fields on the target object (Person or Company) via the metadata API. For form fields with no viable schema mapping, we fall back to a structured JSON custom field or a rich-text notes field to preserve the data.
LeadMaster
Campaign
Twenty CRM
Task (Campaign Reference)
1:1LeadMaster marketing campaigns and associated email sends migrate as campaign records with Person associations. Email content and templates export from LeadMaster and are re-imported as Note records or attached documents. Campaign automation sequences (workflow-triggered email sequences) do not migrate; we document the sequence structure for rebuild as Twenty Workflow filters.
LeadMaster
Landing Page
Twenty CRM
Documentation (no direct mapping)
1:1LeadMaster landing page templates and form integrations are documented during discovery. The page content exports; the hosting and form-to-lead routing cannot be replicated in Twenty CRM because Twenty does not include a native landing page builder. We deliver a list of every landing page with its form fields and routing logic so the customer's team can re-establish the pages in a dedicated marketing platform or rebuild them in a CMS post-migration.
LeadMaster
User / Owner
Twenty CRM
WorkspaceMember
1:1LeadMaster users, roles, and permission levels map to Twenty workspace members. We match by email address. Active/inactive status preserves. Owner assignments on leads, opportunities, and cases migrate by resolving the LeadMaster user ID to the Twenty workspace member email.
LeadMaster
Activity (Notes, Calls, Emails, Tasks)
Twenty CRM
Task, Event, Note
1:1LeadMaster notes, logged calls, email activity, and calendar events migrate to Twenty Task and Event records. Emails migrate as Note records with rich-text body. Call duration, disposition, and recording references transfer to custom fields on the Task. Activity timestamps preserve for timeline ordering. We map to Twenty's standard Task and Event objects using the /graphql endpoint with batch chunking for large activity volumes.
LeadMaster
Smart Queue / Saved Search
Twenty CRM
Note (Documentation)
1:1LeadMaster Smart Queues and saved searches define dynamic record filters. These have no direct equivalent in Twenty CRM. We document each Smart Queue as a written specification with its filter criteria, then provide a mapping table showing which Twenty list views or segment filters each Smart Queue should produce post-migration. The customer's admin configures the equivalent views in Twenty.
LeadMaster
Attachment
Twenty CRM
Attachment / Note
1:1File attachments stored against leads, accounts, or cases in LeadMaster export and re-upload to Twenty. LeadMaster stores files in Azure; we download each attachment, validate file integrity, and attach it to the corresponding Company, Person, or Opportunity record. Large-volume attachment exports require Azure file access credentials and may extend the migration timeline.

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.
LeadMaster gotchas
Workflow logic does not survive migration
Tier-based contact limits can cause import overages
Pricing pages show conflicting tier structures
Email marketing module requires a Pro logon on lower tiers
Custom forms and their responses may have schema gaps
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
Discovery and data audit
We audit the source LeadMaster portal for tier (Free/CRM-Xpress/Enterprise), record counts across Accounts, Leads, Opportunities, Cases, Campaigns, and Activity history. We inventory every active workflow, Smart Queue, custom form, and owner assignment. We also identify the Azure blob storage path for attachments and confirm access credentials. The discovery output is a written migration scope with record counts, a workflow inventory document, and a tier-limit compliance check against the customer's current LeadMaster plan.
Schema design and metadata pre-provisioning
We design the destination schema in Twenty CRM. This includes pre-creating any custom objects (Case, or domain-specific objects matching LeadMaster custom forms) via Twenty's /metadata API, adding custom fields for LeadMaster properties with no direct equivalent, and configuring the Opportunity pipeline stages to match the LeadMaster deal stages. Twenty auto-generates a GraphQL schema from the metadata, which we validate before proceeding to import.
Sandbox migration and reconciliation
We run a full migration into Twenty CRM using a staging instance (or a copy of the production target for self-hosted deployments). The customer's team spot-checks 25-50 records against the LeadMaster source, verifies Opportunity-Company-Person relationship integrity, and confirms activity timeline ordering. Any mapping corrections happen in this phase. The customer signs off the sandbox reconciliation before production migration begins.
Owner and workspace member reconciliation
We extract every distinct LeadMaster Owner referenced on Leads, Opportunities, Cases, and Activity records and match by email against Twenty's workspace members. Owners without a matching Twenty workspace member go to a reconciliation queue. The customer's admin provisions any missing workspace members before record import resumes. Migration cannot proceed past this step because owner references are required on standard objects in Twenty.
Production migration in dependency order
We run production migration in record-dependency order: workspace members validated, Companies imported (from LeadMaster Accounts), Persons imported (from LeadMaster Leads, with the manual conversion gap flagged for post-migration), Opportunities imported with Company and Person lookups resolved, Cases imported to the custom Case object, Activities (Tasks, Events, Notes) via Twenty's GraphQL API with batch chunking, and Attachments downloaded from Azure and re-uploaded to the parent record. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and workflow rebuild handoff
We freeze LeadMaster write access during cutover, run a final delta migration of any records modified during the migration window, then enable Twenty CRM as the system of record. We deliver the workflow inventory document, Smart Queue mapping table, and landing page catalog to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild LeadMaster workflows as Twenty Workflow filters inside the migration scope; that is a separate engagement or an internal admin task.
