Overview
Bella FSM is a field service management platform built around customers, work orders, scheduling, and invoicing — it treats service relationships as secondary to operational execution. Twenty CRM is a modern open-source CRM built around People, Companies, and Opportunities with a customizable data model and API-first architecture. The migration from Bella FSM to Twenty CRM is primarily a data-model translation: Bella's customer records carry company and contact data that must be split into Twenty's Company and People objects, Bella's jobs map to Twenty Tasks or a custom ServiceTicket object, and Bella's equipment and inventory records (add-on features) migrate as custom objects. FlitStack AI sequences the migration so related records resolve in dependency order: Companies first (the one-side of relationships), then People linked via companyId, then Tasks, then custom objects. Scheduling logic, dispatch rules, and invoicing workflows do not transfer — those must be rebuilt in Twenty's workflow builder or handled by your operations team post-migration. We use Bella's CSV export capability and API access where available, mapping each field to its Twenty equivalent and surfacing any Bella-specific constructs (custom data fields, equipment links, parts-on-job) as custom fields or custom objects in Twenty.
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 Bella 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.
Bella FSM
Customer
Twenty CRM
Company + People
1:manyBella FSM stores company name, address, and primary contact fields in a single Customer record. FlitStack AI splits this into a Twenty Company record (company name, domain, industry, address) and a Twenty People record (contact name, email, phone, job title) linked via companyId. The primary contact's details populate the People record; company-level data populates Company.
Bella FSM
Customer (custom fields)
Twenty CRM
People (custom fields)
1:1Bella custom data fields on the Customer page (text input, checkbox, dropdown) map directly to Twenty People custom fields with the same data type. The field name is preserved; dropdown options in Bella map to Twenty select options. All custom fields must be pre-created in Twenty's Settings → Data Model before import runs.
Bella FSM
Job / Work Order
Twenty CRM
Task (or custom ServiceTicket object)
1:1Bella Jobs contain status, description, scheduled date, assigned technician, parts used, labor hours, and checklist results. These map to Twenty Tasks (title, due date, assignee, body with job notes) or a custom ServiceTicket object if the team needs to preserve parts, labor cost, and checklist data as structured fields rather than free-text notes.
Bella FSM
Job (custom fields)
Twenty CRM
Task (custom fields)
1:1Bella custom data fields on the Job page migrate as Twenty Task custom fields. Text fields, checkboxes, and dropdowns map to their Twenty equivalents. Job-specific dropdowns (e.g., job type, priority) require value-mapping if the options differ between Bella and Twenty.
Bella FSM
Equipment Tracking (add-on)
Twenty CRM
Custom Equipment object
1:1Bella FSM's Equipment Tracking stores asset serial numbers, model numbers, maintenance history, and customer linkage. Twenty has no standard Equipment object. FlitStack AI creates a custom Equipment object in Twenty with fields for serialNumber, model, lastServiceDate, and a Company relation. Historical maintenance records migrate as Tasks linked to the Equipment record.
Bella FSM
Inventory (add-on)
Twenty CRM
Custom Inventory Item object
1:1Bella FSM's Advanced Inventory tracks parts across warehouses, trucks, and job sites. This has no Twenty equivalent. We create a custom InventoryItem object with fields for partNumber, description, quantityOnHand, location, and a relation to Company for parts assigned to a customer site.
Bella FSM
Invoice / Quote
Twenty CRM
Custom Invoice object or Opportunity line items
1:1Bella FSM's invoicing module generates line-item invoices with payment status. Twenty CRM has no native invoicing. We preserve invoice data as a custom Invoice object (invoiceNumber, amount, status, date, line items) linked to the associated Company or People record. Payment history is stored as custom fields on the Invoice record.
Bella FSM
Vendor
Twenty CRM
Company (with vendorType tag)
1:1Bella FSM's Vendor records contain name, contact, and payment terms. These map to Twenty Company records with a vendorType custom field set to 'Vendor'. The same Company object is used for both customers and vendors — a type tag distinguishes them.
Bella FSM
Employee / Technician
Twenty CRM
WorkspaceMember
1:1Bella FSM employees and technicians map to Twenty WorkspaceMembers. FlitStack AI resolves Bella employee email addresses against Twenty user invitations — technicians must be invited to Twenty before migration so job assignments can map to the correct assignee. Unmatched technicians are flagged for manual resolution.
Bella FSM
Attachment / File
Twenty CRM
Note (with file attachment)
1:1Bella FSM file attachments on customers, jobs, or equipment re-upload to Twenty as Notes with file attachments. The original file name and create date are preserved. Bella's File Attachments add-on content migrates as Twenty Note records linked to the relevant People, Company, or Task.
Bella FSM
Schedule / Calendar event
Twenty CRM
No equivalent (not migrated)
1:1Bella FSM's scheduling and dispatch calendar (drag-drop calendar, technician routing, real-time dispatch board) has no Twenty CRM equivalent. Scheduling data is not migrated. Teams rebuild scheduling logic in Twenty's workflow builder or integrate a dedicated scheduling tool post-migration.
Bella FSM
Workflow / Automation
Twenty CRM
No equivalent (not migrated)
1:1Bella FSM automations and dispatch rules do not transfer to Twenty CRM. These include time-based triggers, event-driven actions, and conditional logic built within Bella's workflow engine. Twenty's own workflow builder can recreate similar time-based and event-based automations, but the specific rules must be documented and manually rebuilt. FlitStack AI exports Bella workflow definitions as a reference document for your operations team to use during the rebuild process.

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.
Bella FSM gotchas
No public API for bulk data export
Custom data fields lack a published schema
Equipment Tracking requires paid add-on tier
Invoice payment status is point-in-time at export
Review volume too small for reliable sentiment analysis
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 Bella FSM data and build the Twenty schema plan
FlitStack AI exports a full inventory of Bella FSM records: customer count, job count, equipment records (if add-on active), inventory items (if add-on active), invoice history, and all custom data fields on customer and job pages. We cross-reference this against Twenty's standard object model and generate a schema plan: which objects to create (Equipment__c, InventoryItem__c, Invoice__c), which fields to add as custom on standard objects (People, Company, Task), and the import order that satisfies Twenty's dependency rules (Companies first, then People, then Tasks, then custom objects).
Pre-create Twenty custom fields and objects
Your Twenty admin (or our team) creates all custom fields and custom objects identified in the schema plan before the migration runs. Custom dropdown fields in Bella must have their option lists replicated in Twenty's field configuration. Custom objects (Equipment, InventoryItem, Invoice) are created in Settings → Data Model with the field structure specified in the schema plan. WorkspaceMembers (technicians and employees) are invited to Twenty so owner resolution can match by email during migration.
Split Bella customers into Company and People records
FlitStack AI processes Bella Customer records in two passes. First pass creates Twenty Company records for each Bella customer — company name, address, domain. Second pass creates Twenty People records linked via companyId — first name, last name, email, phone, job title. Bella custom data fields on the customer page migrate as People custom fields during the second pass. For Bella customers that represent pure companies (no individual contact), we create a Company-only record with no linked People.
Migrate jobs as Tasks and preserve equipment, inventory, and invoice data
Bella Jobs migrate as Twenty Tasks: job number becomes task title, description becomes task body, status maps via value mapping, assigned technician resolves by email match to Twenty WorkspaceMembers, and Bella custom data fields on the job page migrate as Task custom fields. Equipment records (if present) create Equipment__c custom object records linked to the associated Company. Inventory items create InventoryItem__c records. Invoice history creates Invoice__c records linked to the Company. Each custom object record preserves the original Bella create date as a custom field.
Run sample migration with field-level diff and cut over with delta pickup
A representative slice of 100–500 records migrates first — spanning customers, jobs, equipment, and invoices. We generate a field-level diff between the Bella source and Twenty destination so you can verify split logic (Company vs. People), custom field mapping, technician resolution, and equipment-company relations. After approval, the full migration runs with a delta-pickup window of 24–48 hours that captures any Bella records modified during cutover. Audit log records every operation; one-click rollback is available if reconciliation fails.
