Overview
Moving from Leadtrekker Lead Management to Twenty CRM is a platform-class migration: Leadtrekker is a South African-origin lead management tool priced in Rand with a Lead-centric data model, while Twenty CRM is an open-source, self-hostable CRM with a People-centric model that supports custom objects, custom fields, and role-based permissions from the first workspace. The primary mapping challenge is resolving Leadtrekker's single Lead record — carrying contact details, source attribution, assignment history, and notification rules — into Twenty's People object with custom fields for lead source and owner. Activities (notes, call logs, email events) migrate as Timeline Entries with the original timestamp preserved. We do not migrate notification preferences (platform runtime settings, not exportable data) or Leadtrekker's assignment rules (no Twenty equivalent); we document both in the handoff inventory. Twenty's self-hosted deployment option means the customer controls hosting, storage, and access logs — a key differentiator for teams leaving a ZA-denominated SaaS platform.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Leadtrekker Lead Management 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.
Leadtrekker Lead Management
Lead
Twenty CRM
Person
1:1Leadtrekker Lead records map to Twenty CRM Person records. Standard fields (name, email, phone, status, lead source) map directly. The Lead's assigned owner maps to the Person's workspace member assignment. We preserve the Leadtrekker status value in a custom field lt_original_status__c for audit. Because Twenty's Person object is a unified contact model without a separate Lead conversion step, Leadtrekker leads land directly as Twenty People without a split.
Leadtrekker Lead Management
Activity (Notes, Call Logs, Emails)
Twenty CRM
Timeline Entry
1:1Leadtrekker activity records (notes, call logs, email events) attached to a Lead migrate to Twenty CRM Timeline Entries on the corresponding Person record. Each Timeline Entry preserves the original timestamp and user attribution. Call disposition and duration from Leadtrekker call logs migrate as custom fields on the Timeline Entry. We resolve the parent Person by matching the Lead's email address to Twenty's Person email field.
Leadtrekker Lead Management
Lead Source
Twenty CRM
Custom Field on Person
lossyLeadtrekker's lead source attribution (website form, campaign, referral) is stored as a Lead property. We create a custom field lead_source__c on Twenty's Person object and populate it from the Leadtrekker source label. If the customer uses multiple source values, we normalize them to a consistent label set during migration to avoid fragmentation in Twenty's filtering.
Leadtrekker Lead Management
User
Twenty CRM
Workspace Member
1:1Leadtrekker user accounts (name, email, login) map to Twenty CRM workspace members. We export the user roster by email match. Passwords and session tokens do not transfer; each user receives a Twenty invitation link post-migration. If a Leadtrekker user is inactive or has no email match, we flag them in the reconciliation queue for the customer admin to provision.
Leadtrekker Lead Management
User Group
Twenty CRM
Workspace Role or Team
lossyLeadtrekker user groups assign lead-level view and edit permissions to subsets of users. Twenty CRM uses workspace roles (Viewer, Editor, Admin) with optional field-level restrictions. We extract the full Leadtrekker group membership roster, map each group to the closest Twenty role (or create a custom role if the permission semantics require it), and document the mapping. Permission logic is reconfigured manually post-migration using Twenty's role settings.
Leadtrekker Lead Management
Reminder
Twenty CRM
Task
1:1Leadtrekker follow-up reminders carry a due date and owner assignment. We convert these to Twenty CRM Task records attached to the Person. Due date and assignee migrate directly. Completed status and completion timestamp transfer to the Task's status and completion date fields.
Leadtrekker Lead Management
Custom Field (Lead)
Twenty CRM
Custom Field on Person
lossyAny Leadtrekker custom fields added to the Lead object require explicit field-level mapping because Leadtrekker does not publish a stable field taxonomy. We conduct a discovery probe against the Leadtrekker API during scoping to enumerate all active custom fields, then create matching custom fields on Twenty's Person object before migration. Field type mapping follows: text to string, number to number, date to date, dropdown to select.
Leadtrekker Lead Management
Company (if applicable)
Twenty CRM
Company
1:1If Leadtrekker Lead records contain company name and the customer has a meaningful number of company-attributed leads, we create Twenty CRM Company records and link Person records via the company relationship. This mapping is optional and activated only if the company field is populated in more than 30 percent of Lead records.
Leadtrekker Lead Management
Notification Preferences
Twenty CRM
Not Migrated
1:1Leadtrekker SMS and email notification preferences are platform runtime settings, not stored as exportable data records. We document all notification-trigger events observed during extraction (assignment alerts, status change alerts, reminder notifications) in the handoff inventory. The customer manually configures notification rules in Twenty CRM post-migration using Twenty's workflow actions.
Leadtrekker Lead Management
Assignment Rules
Twenty CRM
Not Migrated
1:1Leadtrekker's automatic lead assignment rules (round-robin, territory-based, load-balanced) are platform logic with no direct Twenty CRM equivalent. We extract and document the active assignment rules as a written inventory with trigger conditions, target groups, and rule order. The customer rebuilds assignment logic in Twenty CRM using workflow filters and member assignment actions.

Leadtrekker Lead Management gotchas
Pricing in South African Rand obscures true cost
Notification preferences cannot be exported
API rate limits are undocumented
User group permissions require manual remapping
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 API probe
We audit the Leadtrekker portal: record counts (Leads, Activities, Users, Groups, Reminders), custom field inventory via API probe, active notification and assignment rules, and API authentication testing to determine available export endpoints and safe pacing rates. We pair this with a Twenty CRM workspace setup confirmation (self-hosted or cloud) and workspace configuration review. The discovery output is a written migration scope document with record counts, field inventory, and a confirmed extraction strategy.
Schema design in Twenty CRM
We design the destination schema in the Twenty CRM workspace. This includes creating the lead_source__c custom field on Person, creating any custom fields discovered during the Leadtrekker API probe, configuring workspace roles (mapped from Leadtrekker user groups), and setting up the initial Person layout. If Company records are in scope, we create the Company object and the Person-Company relationship. Schema is validated in a staging workspace before production migration begins.
Sandbox migration and reconciliation
We run a full migration into a Twenty CRM staging workspace using a representative data sample (minimum 100 Leads, 200 Activities). The customer reconciles record counts, spot-checks 20-30 random Person records against the Leadtrekker source, and confirms the activity timeline renders correctly in Twenty. Any mapping corrections — field name mismatches, custom field omissions, user lookup failures — are resolved here before production.
User provisioning and group mapping
We extract every distinct Leadtrekker user and match by email against the Twenty CRM workspace members. Users without a matching Twenty account go to a reconciliation queue. The customer provisions any missing Twenty workspace members and confirms role assignments mapped from the Leadtrekker group roster. Migration cannot proceed past this step because Person owner lookups require a valid workspace member reference.
Production migration in dependency order
We run production migration in record order: Workspace Members (validated), Persons (from Leads with email-matched owner), Timeline Entries (from Activities resolved to parent Person by email), Tasks (from Reminders), and Custom Field data (populated on existing Person records). Each phase emits a row-count reconciliation report. Notification preferences and assignment rules are not extracted as data — they are documented in the handoff inventory during this phase.
Cutover, validation, and handoff
We freeze Leadtrekker writes 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 notification and assignment rule inventory to the customer's admin team. We support a five-business-day hypercare window for reconciliation issues. We do not rebuild Leadtrekker notification preferences or assignment rules as Twenty workflows inside the migration scope; that is a separate configuration engagement.
