Overview
Service Suite FSM and Twenty CRM take fundamentally different approaches to organizing field-service data. Service Suite FSM bundles work orders, scheduling, dispatch, technician management, and asset tracking into a unified operational platform with REST APIs secured by OAuth 2.0. Twenty CRM is a modern, open-source CRM built on React, NestJS, and PostgreSQL that exposes standard People, Companies, Opportunities, Notes, and Tasks objects plus unlimited custom objects via Settings → Data Model. Teams move from Service Suite FSM to Twenty when they want a CRM-first foundation they can extend with custom objects, self-host, or connect via webhooks without per-seat feature gating. The migration carries Service Suite FSM customers, contacts, work orders, assets, and tasks into Twenty's object model. Scheduling and dispatch logic that lives as Service Suite FSM workflow rules must be rebuilt using Twenty's workflow builder (which lacks native sequencing as of 2026). We use Service Suite FSM's REST API with scoped read access to extract data, transform field formats, resolve technician-to-workspace-member mappings, and load into Twenty via CSV import (up to 20,000 records per batch) or direct API calls at 100–200 requests per minute depending on your Twenty plan.
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 Service Suite FSM 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.
Service Suite FSM
Customer
Twenty CRM
Company
1:1Service Suite FSM customers map to Twenty CRM Companies. Customer addresses, contact information, and billing details consolidate into Twenty's Company record. When a Service Suite FSM customer has multiple service locations, each location can migrate as a separate Company record linked by a parent-company relation in Twenty.
Service Suite FSM
Contact
Twenty CRM
Person
1:1Service Suite FSM contact records map 1:1 to Twenty CRM People. Each contact's name, email, phone, job title, and role transfer directly. The contact's primary customer link becomes the Person's companyId relation to the corresponding Twenty Company record. Additional FSM fields such as contact type and department are preserved as custom fields, and the original FSM contact ID is stored in a custom Source_System_ID__c field for traceability.
Service Suite FSM
Work Order
Twenty CRM
Opportunity (or custom WorkOrder object)
1:1Service Suite FSM work orders map to Twenty Opportunities if teams track jobs as deals with stage progression. If FSM work orders have FSM-specific statuses (dispatched, in-progress, completed, invoiced) that do not map to standard opportunity stages, we create a custom WorkOrder object in Twenty with Stage pick-list mirroring FSM statuses and relations to Person, Company, and WorkspaceMember records.
Service Suite FSM
Work Order Status
Twenty CRM
Opportunity StageName (or WorkOrder__c.Stage__c)
1:1FSM work order statuses map value-by-value to Twenty opportunity stages or a custom pick-list. Common FSM statuses (Scheduled, En Route, In Progress, Completed, Cancelled) map to corresponding stage names in Twenty. Stage-entered timestamps preserve original FSM status-change dates as custom datetime fields.
Service Suite FSM
Technician
Twenty CRM
WorkspaceMember
1:1Service Suite FSM technician records map to Twenty CRM workspace members. Technician skills, certifications, and service regions migrate as custom fields on the WorkspaceMember record. Users must be invited and accept before records reference them as assignees; we flag unresolved technicians before migration.
Service Suite FSM
Asset
Twenty CRM
Asset__c (custom object)
1:1Service Suite FSM assets—installed equipment linked to customers with serial numbers, warranty dates, and service history—require a custom Asset object in Twenty. The custom object includes fields for customer link (companyId), location, serial number, warranty expiry, and asset type. Service history attaches as related Task records.
Service Suite FSM
Task
Twenty CRM
Task
1:1Service Suite FSM tasks map directly to Twenty CRM Tasks. Task title, description, due date, assignee (workspace member), and status transfer. Tasks linked to work orders relate to the corresponding Opportunity or custom WorkOrder record in Twenty via a relation field.
Service Suite FSM
Schedule / Dispatch Record
Twenty CRM
Task (with custom scheduling fields)
1:1FSM scheduling and dispatch assignments—technician-to-job mappings with time windows and route data—migrate as Twenty Tasks with custom datetime fields for scheduled start/end and a relation to the assigned WorkspaceMember. Route optimization data not natively supported in Twenty is preserved as a custom text field.
Service Suite FSM
Service History
Twenty CRM
Task
1:1FSM service history entries (completed jobs, maintenance visits, parts used) migrate as completed Tasks related to the corresponding Asset__c and Opportunity records in Twenty. Original completion timestamps and technician assignment are preserved for service reporting continuity. The Task title reflects the service type (e.g., ‘Preventive Maintenance’ or ‘Repair’), the description captures notes and parts consumed, and fields store service type, work order reference, and skill used, ensuring audit trail.
Service Suite FSM
Custom Objects (FSM-specific modules)
Twenty CRM
Custom Object
1:1Service Suite FSM custom objects created for FSM-specific modules (e.g., inventory items, parts catalogs, certification records) map 1:1 to Twenty custom objects. Custom object relationships in Service Suite FSM that use N:N associations need junction objects in Twenty; we surface these in the pre-migration mapping plan.
Service Suite FSM
Attachment / File
Twenty CRM
Note (with file attachment)
1:1FSM file attachments on work orders, assets, or customers re-upload to Twenty as Notes with attached files. File size limits apply (Twenty's import size constraints); large files may require chunking or external storage links. Inline images in notes are downloaded and rehosted.
Service Suite FSM
Workflow / Automation Rules
Twenty CRM
N/A
1:1Service Suite FSM workflow rules for scheduling triggers, dispatch logic, and automated notifications do not have a direct equivalent in Twenty CRM. Twenty's workflow builder supports basic automation but lacks FSM-specific sequencing. We export workflow definitions as a rebuild reference document for your team to recreate in Twenty's Settings → Workflows.

Pair-specific challenges
Migration approach
Audit Service Suite FSM data and design Twenty schema
We extract a full data inventory from your Service Suite FSM account—customers, contacts, work orders, assets, tasks, technicians, and any custom objects or fields. We compare your FSM schema against Twenty's standard objects and identify gaps. For every FSM work-order status, custom field, and asset type, we produce a Twenty schema setup plan specifying which standard fields to use, which custom objects and fields to create in Settings → Data Model, and what pick-list values to configure before import begins.
Invite and confirm all workspace members in Twenty
Before any records migrate, your admin invites all technicians, dispatchers, and users from Service Suite FSM to Twenty via Settings → Members. Each invite must be accepted. We run an email-match resolution pass against your FSM technician and user records to map them to Twenty workspace members. Any FSM user without a matching Twenty account gets flagged in a pre-flight report; your team either creates the Twenty account first or assigns those records to a fallback workspace member before migration.
Migrate Companies first, then People, then Opportunities
Twenty's CSV import enforces referential integrity: parent records must exist before child records can reference them. We sequence the migration as: (1) Companies from Service Suite FSM customers, (2) People from contacts linked to those companies via companyId, (3) Custom Asset__c records from FSM assets, (4) Opportunities from FSM work orders with assigneeId and companyId resolved, and (5) Tasks from FSM tasks and service history. Each batch runs as a separate import pass with error reporting and row-level validation.
Run a sample migration with field-level diff and validation
We migrate a representative slice—typically 200–500 records spanning customers, contacts, work orders, assets, and tasks—before committing the full dataset. We generate a field-level diff comparing source FSM values against what landed in Twenty so you can verify technician assignment, status-to-stage mapping, date preservation, and custom field population. Any mapping errors surface here; we adjust transformation logic and re-run the sample until the diff passes your review.
Execute full migration with delta-pickup window
After sample validation, we run the full migration in read-only mode against Service Suite FSM. Your team continues working in Service Suite FSM during the migration. A delta-pickup window of 24–48 hours captures any records created or modified after the migration snapshot, and we re-import those deltas to bring Twenty to parity. All operations are logged in an audit trail. If reconciliation reveals missing or mismatched records, one-click rollback reverts the Twenty state for a clean retry.
