Overview

What this migration involves

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.

What's pushing teams away

  • Mobile app access for field technicians was reported as unreliable in at least one verified review, with staff unable to retrieve job or customer information from smartphones or tablets.
  • The built-in accounting module is limited in scope, pushing users with more complex bookkeeping needs toward separate accounting software that may not sync cleanly with exported data.
  • Support response times were described as slow by some users, with tech support taking up to a week to respond to critical issues during field operations.
  • A review flagged inaccurate reporting outputs, raising concerns about data integrity when exporting historical records for migration purposes.
  • Small review corpus (7 verified reviews on major platforms) makes it difficult to assess long-term reliability and creates risk for businesses with mission-critical field operations.

Choosing

Twenty CRM

What's pulling them in

  • Top open-source CRM on GitHub with 40.6K stars, giving teams full source code access and infrastructure ownership without per-feature licensing surprises.
  • Free self-hosting under AGPL-3.0 means unlimited users and custom objects for the cost of cloud infrastructure alone, typically $20–100/month.
  • Pricing page explicitly mocks competitors for charging add-on fees for API access, webhooks, and workflows — transparency that resonates with RevOps teams burned by Salesforce.
  • Unlimited custom objects and fields with no price impact, letting teams shape the data model to their business rather than forcing business into rigid schemas.
  • Modern TypeScript/React/PostgreSQL stack means developer-led teams can extend, self-host, or integrate without fighting legacy architecture.

Object mapping

How Bella FSM objects map to Twenty CRM

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

maps to

Twenty CRM

Company + People

1:many
Fully supported

Bella 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)

maps to

Twenty CRM

People (custom fields)

1:1
Fully supported

Bella 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

maps to

Twenty CRM

Task (or custom ServiceTicket object)

1:1
Fully supported

Bella 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)

maps to

Twenty CRM

Task (custom fields)

1:1
Fully supported

Bella 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)

maps to

Twenty CRM

Custom Equipment object

1:1
Fully supported

Bella 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)

maps to

Twenty CRM

Custom Inventory Item object

1:1
Fully supported

Bella 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

maps to

Twenty CRM

Custom Invoice object or Opportunity line items

1:1
Fully supported

Bella 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

maps to

Twenty CRM

Company (with vendorType tag)

1:1
Fully supported

Bella 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

maps to

Twenty CRM

WorkspaceMember

1:1
Fully supported

Bella 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

maps to

Twenty CRM

Note (with file attachment)

1:1
Fully supported

Bella 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

maps to

Twenty CRM

No equivalent (not migrated)

1:1
Fully supported

Bella 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

maps to

Twenty CRM

No equivalent (not migrated)

1:1
Fully supported

Bella 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.

Pair-specific challenges

  • Bella FSM has no native Company object — customers and companies are merged

    Bella FSM stores customer records that blend company-level data (company name, address) with contact-level data (first name, last name, email, phone) in a single object. Twenty CRM separates Companies and People as distinct objects with a required companyId relation on People. FlitStack AI splits each Bella Customer record into a Company and a People record, creating the Company first and linking the People record by companyId. If a Bella customer record has no separate contact (e.g., a commercial account billed to the company name), we create a Company-only record and skip the People link. This disambiguation step adds planning time for accounts with ambiguous customer records.

  • Equipment Tracking and Advanced Inventory are Bella add-ons that require custom object creation in Twenty

    Bella FSM's Equipment Tracking and Advanced Inventory modules are paid add-ons ($10/month each) that store asset serial numbers, maintenance history, parts inventory, and site-level stock. Twenty CRM has no standard objects for equipment or inventory — these must be created as custom objects (Equipment__c and InventoryItem__c) in Twenty's Settings → Data Model before migration. If your team uses these add-ons heavily, the custom-object schema setup is the longest planning step in the migration. We deliver a schema plan specifying field names, types, and relations for each custom object so your Twenty admin can pre-create them before data import.

  • Scheduling and dispatch data cannot migrate to Twenty's task model

    Bella FSM's drag-drop calendar, technician dispatch board, and recurring appointment rules are core operational features that have no equivalent in Twenty CRM. Twenty's Tasks object supports due dates and assignees but not time-window scheduling, route optimization, or technician capacity views. Migrating Bella scheduling data into Twenty Tasks would produce misleading calendar entries that do not reflect the original dispatch logic. FlitStack AI does not migrate scheduling records. Teams must rebuild dispatch workflows either in Twenty's workflow builder (for time-based triggers) or integrate a dedicated scheduling tool post-migration.

  • Bella FSM custom data fields must be pre-created in Twenty before import

    Bella FSM allows custom data fields on both the Customer page and the Job page — text inputs, checkboxes, and dropdown menus with custom option lists. Twenty CRM's CSV import creates records but not fields; all custom fields must exist in Settings → Data Model before import runs. If a Bella account has 15 custom fields across customer and job pages, those 15 fields must be manually created in Twenty first. FlitStack AI generates a field-creation checklist from the Bella custom field audit so nothing is missed before the migration window opens.

  • Invoicing history migrates as a reference object, not a working module

    Bella FSM's invoicing module generates line-item invoices, tracks payment status, and integrates with Stripe for credit card processing. Twenty CRM has no native invoicing module — invoice data can only be preserved as a custom object with read-only fields. The invoice amount, status, and date migrate as custom fields on a custom Invoice object linked to the Company, but Twenty cannot generate new invoices or process payments. Teams that rely on Bella's billing features need a separate invoicing tool post-migration.

Migration approach

Six steps for a successful Bella FSM to Twenty CRM data migration

  1. 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).

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Strengths

  • Per-user pricing starts at $35/month with all standard FSM features included and no long-term contract required.
  • Cloud-based access from any device with an internet connection means no on-premise software or hardware to install.
  • Included CRM module for managing customer history, contacts, and communication in the same platform as scheduling.
  • Built-in drag-and-drop calendar with multiple views, color coding, and recurring appointment support for dispatch operations.
  • Responsive customer support cited positively across multiple reviews, with the team willing to help with data imports and onboarding.

Weaknesses

  • No publicly documented API means all data extraction relies on built-in reports or direct database access, limiting automation options for large migrations.
  • Accounting module is deliberately limited, pushing businesses with complex bookkeeping needs to separate tools that may not sync cleanly on export.
  • Review corpus is very small (7 verified reviews across major platforms), making independent assessment of reliability difficult.
  • Mobile app reliability was flagged in at least one verified review, with field technicians unable to access job information from smartphones.
  • Custom data field schema is per-account and not governed by a published data dictionary, requiring manual field-by-field discovery during migration scoping.

Strengths

  • AGPL-3.0 open-source license with full source code on GitHub — no vendor lock-in, no sunset risk.
  • Unlimited users and unlimited custom objects on self-hosted, with no feature gating based on headcount.
  • REST and GraphQL APIs available on all paid tiers, not locked behind an enterprise add-on fee.
  • MCP server and webhooks shipped as standard features, not premium upgrades.
  • Modern PostgreSQL-backed data model that developer teams can query, extend, and self-host.

Weaknesses

  • Recent v1.0 release means limited production hardening compared to CRMs with multi-year operational track records.
  • No native email sequencing or sales engagement tools — follow-up cadences require a separate platform.
  • No native two-way email sync or inbox integration, requiring third-party connectors for full activity logging.
  • Self-hosting 'free' pricing hides real infrastructure and DevOps costs that stack up over time.
  • Workflow automation is functional but lacks the complexity needed for sophisticated multi-step sales motions.

Most Bella FSM to Twenty CRM migrations complete in 48–72 hours of clock time for setups with under 10,000 records and minimal custom objects. Teams with active Equipment Tracking and Advanced Inventory add-ons, or more than 10,000 records, extend to 7–14 days. The longest single step is pre-creating the Twenty custom objects and fields — plan 3–5 business days for schema setup before data import runs. Custom field creation in Settings → Data Model must complete before the CSV import step.
