Overview
Bella FSM organizes field service operations around Jobs, Work Orders, Customers, and Equipment. Nutshell organizes sales around People, Companies, Leads, and Deals. The two platforms share Contacts, Companies, Notes, and Custom Fields as common objects, but Bella's work-order lifecycle, equipment tracking, and scheduling engine have no Nutshell equivalent — those records migrate as custom-field metadata or become reference notes for manual rebuild. FlitStack AI extracts Bella data via API using your account credentials with scoped read access. We resolve Bella owner email addresses against Nutshell users, then load People, Companies, Leads, and any custom fields that have direct or transformed counterparts. Equipment records from Bella's Equipment module become a custom Nutshell object so your team retains service history. Work order status, line items, and scheduling data surface as read-only notes on the linked Person or Company record — your Nutshell admin decides how to structure the rebuild. The delta-pickup window (24–48 hours) captures any Bella records modified between the initial extract and the cutover moment. Audit logs record every field-level operation. One-click rollback restores the pre-migration state if reconciliation fails.
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 Nutshell, 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
Nutshell
Person
1:1Bella Customers map directly to Nutshell People. All standard contact fields (name, email, phone, address) transfer. Custom fields on the Bella Customer page migrate as Nutshell custom fields on the Person record. The Bella Customer ID is preserved as Source_System_ID__c for traceability.
Bella FSM
Customer
Nutshell
Lead
1:manyBella Customers with no linked Work Orders or invoices split to Nutshell Leads — these are prospects who were entered but never converted to active service accounts. Customers with at least one Work Order map to Nutshell People to preserve the active account history.
Bella FSM
Company
Nutshell
Company
1:1Bella Companies map to Nutshell Companies in a one-to-one relationship. All standard fields transfer including company name, domain/website, physical address, and industry classification. Bella parent/child company hierarchies preserve as Nutshell Company parent relationships when the destination Nutshell account configuration includes the parent-company field enabled.
Bella FSM
Work Order
Nutshell
Activity / Note on Person
1:1Bella Work Orders have no Nutshell equivalent. We extract Work Order summary fields (status, description, assigned technician, line items) and write them as a formatted Note on the linked Person record. Your team rebuilds the active job workflow using Nutshell Tasks and custom fields.
Bella FSM
Equipment
Nutshell
Custom Object (Equipment__c) or Company custom fields
1:1Bella Equipment records migrate to a Nutshell custom object (Equipment__c) with a lookup to the Company record. Fields include equipment name, model, serial number, install date, and service notes. If Nutshell account tier limits custom objects, fields collapse to custom fields on the Company record instead.
Bella FSM
Job / Service Visit
Nutshell
Activity on Person
1:1Individual Job or Service Visit records from Bella become Nutshell Activity records (Tasks) linked to the Person. Timestamps and technician notes transfer; scheduling time slots do not since Nutshell has no calendar-slot concept. The activity type is tagged 'Field Service' for filtering.
Bella FSM
Invoice
Nutshell
Note on Person
1:1Bella invoices (including line items, amounts, payment status, and QuickBooks sync flags) write as a Note on the Person record. Invoice PDF URLs from Bella's file attachment store are preserved as links. Nutshell does not have invoice objects — your accounting team references these notes and recreates invoices in QuickBooks or your chosen accounting tool.
Bella FSM
Custom Field (Customer)
Nutshell
Custom Field (Person)
1:1Bella custom fields on Customers (text input, checkbox, dropdown) map to Nutshell custom fields on People. Text fields transfer directly. Checkbox fields become Nutshell checkboxes. Dropdown fields with custom option lists require value mapping — we create matching picklist values in Nutshell before the migration loads.
Bella FSM
Custom Field (Job)
Nutshell
Custom Field (Person) or Note
1:1Bella custom fields on Work Orders that hold critical reference data (e.g., contract type, warranty expiration, priority tier) migrate as custom fields on the linked Person record so the data remains accessible after the Work Order is converted to a note.
Bella FSM
File Attachments
Nutshell
File / Attachment on Person or Company
1:1Bella file attachments including images, documents, and signed PDFs are re-uploaded to Nutshell's attachment system and linked to the corresponding Person or Company record based on the source object relationship. Nutshell's hosting enforces specific file size limits that may require compression for large media files or alternatively reference cloud storage links where file sizes exceed the platform threshold.
Bella FSM
User / Owner
Nutshell
User
1:1Bella user accounts resolve to Nutshell users by email address. Unmatched Bella owners are flagged before migration — your team either creates Nutshell accounts for them or assigns their records to a fallback user. User roles and permissions do not transfer since those are destination-side configuration.
Bella FSM
Vendor
Nutshell
Company (tagged Vendor)
1:1Bella Vendors map to Nutshell Companies with a custom 'Vendor' checkbox field set to true, allowing clear differentiation from customer accounts in list views and reports. Vendor contact information migrates as a Person record linked to that Company, maintaining the relational structure. This organization keeps vendor records fully searchable alongside customer accounts in Nutshell's unified database.

Migration approach
Discovery and schema mapping
FlitStack AI connects to Bella FSM using your API credentials with scoped read access. We extract the full object inventory: Customer count, Company count, Work Order count, Equipment records, custom field definitions, and owner/user list. We generate a mapping plan that identifies which Bella objects map directly to Nutshell, which require a custom object or custom field first, and which have no equivalent and will become Notes. Your team reviews and approves the mapping plan before any data moves.
Pre-create Nutshell custom fields and objects
Based on the mapping plan, your Nutshell admin (or our team acting with admin credentials) creates any missing custom fields on Person, Company, and Lead objects, plus the Equipment__c custom object if your plan supports it. Custom picklist option values are populated to match Bella's dropdown values. This step ensures the Nutshell schema is ready before the migration load — we cannot load into fields that don't exist yet.
Owner resolution by email
Bella user email addresses are matched against existing Nutshell user accounts. We generate an owner-resolution report listing matched owners, unmatched owners, and a fallback assignment for each. Unmatched owners require either a new Nutshell account invitation or a decision to reassign their records to a designated fallback user before the migration runs. No record loads without a valid Nutshell owner reference.
Sample migration with field-level diff
A representative slice of 100–300 records migrates first, spanning Customers, Companies, Equipment, and Work Orders. We produce a field-level diff showing what landed in each Nutshell field, any null values from missing source data, and any mapping decisions that need adjustment. Your team reviews the sample in Nutshell before we commit to the full run. Common adjustments at this stage include custom picklist value creation, equipment field scope, and note formatting preferences.
Full migration with delta pickup
The full dataset migrates into Nutshell. A delta-pickup window of 24–48 hours after the initial load captures any Bella records created or modified during the cutover period. All operations are logged in an audit trail. If reconciliation finds discrepancies (record count mismatches, missing required fields), FlitStack AI triggers a one-click rollback to the pre-migration state. Your team retains read access to Bella during this window so operations continue without interruption.
Post-migration handoff and rebuild reference
We deliver a rebuild reference package that documents the Work Order structure, scheduling fields, equipment history, and custom field definitions from Bella — organized so your Nutshell admin can recreate the active job workflow using Nutshell Tasks, custom fields, and automation tools. We do not rebuild Nutshell automations, but we provide the structural blueprint so your team or a Nutshell consultant can implement it. QuickBooks integration settings and eSignature configuration export as reference documents.
