Overview
Teams move from Gearbox to Twenty CRM when they want full data ownership, open-source infrastructure, and a CRM built on a clean TypeScript and PostgreSQL stack. Gearbox organizes fleet-maintenance data around Contractors, Companies, Work Orders, and Vehicles. Twenty CRM maps these to People (for contacts and contractors), Companies, Opportunities (for work orders and deals), and custom objects (for vehicle-asset records). FlitStack AI extracts Gearbox data via its REST API, transforms all field names and types, and loads into Twenty through its GraphQL batch-import endpoint. Work-order status, service type, priority, and cost land as custom fields on Twenty Opportunities. Vehicle-asset associations migrate as a custom object with a relation to the parent Company record. Gearbox workflows and scheduling automations do not migrate — FlitStack exports Gearbox workflow definitions as a rebuild reference for Twenty's workflow builder. The migration runs with scoped read-only access on Gearbox, so your team keeps operating during the cutover. A delta-pickup window captures any work orders modified or created between the initial extraction and the final verification pass.
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 Gearbox 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.
Gearbox
Contractor / Person
Twenty CRM
People
1:1Gearbox contractor records map directly to Twenty People. Gearbox stores first name, last name, email, phone, job title, and company association. These map 1:1 to Twenty People fields. Contractor status (Active, Inactive) migrates as a custom Select field on People if the field is used to filter pipelines rather than just archive records.
Gearbox
Company / Organization
Twenty CRM
Company
1:1Gearbox organization records map to Twenty Companies. Standard fields — name, domain, industry, employee count, annual revenue, address — map to their Twenty counterparts. Gearbox's parent-company hierarchy maps to Twenty's relation field on Company if Gearbox exposes that relationship in its API export.
Gearbox
Work Order
Twenty CRM
Opportunity
1:1Work orders are the core entity in Gearbox's fleet model. FlitStack AI maps Work Order name to Opportunity name, scheduled date to Close Date, and Work Order status to Opportunity Stage via value mapping (Active → Open/Qualification, Completed → Closed Won, Cancelled → Closed Lost). Custom fields like service type, priority, and cost migrate to custom fields on the Opportunity.
Gearbox
Work Order Stage
Twenty CRM
Opportunity Stage
1:1Gearbox stage names vary by setup but typically include states like Scheduled, In Progress, Pending Parts, Completed, and Cancelled. Each value is mapped to a Twenty Opportunity Stage. Stage transition timestamps from Gearbox are preserved as custom datetime fields on the Opportunity record.
Gearbox
Vehicle / Asset
Twenty CRM
Custom Object: Vehicle
1:1Gearbox vehicle and asset records have no direct Twenty CRM equivalent — Twenty does not ship a native asset or fleet object. FlitStack AI creates a Vehicle custom object in Twenty via Settings → Data Model, adds fields for registration, make/model, mileage, and last service date, then links each Vehicle record to its parent Company. Work orders reference the Vehicle via a relation field on the custom object.
Gearbox
Work Order Assignment
Twenty CRM
Opportunity Assignee / Custom Relation
1:1Gearbox assigns Work Orders to Gearbox workspace users (technicians or contractors). Twenty Opportunities have an assignee field that links to a Workspace Member. FlitStack resolves Gearbox user emails against invited Twenty Workspace Members and maps the assignment. Unresolved users are flagged before migration so the Twenty admin can invite them first.
Gearbox
Gearbox User
Twenty CRM
Workspace Member
1:1Gearbox workspace users map to Twenty Workspace Members. Before migration, all Gearbox users who own records should be invited to the Twenty workspace via Settings → Members. FlitStack validates that a Workspace Member exists for each resolved owner before committing the Opportunity import.
Gearbox
Work Order Notes / Attachments
Twenty CRM
Note / Task
1:1Work order notes and inspection comments in Gearbox migrate to Twenty Notes attached to the corresponding Opportunity record. File attachments are re-uploaded to Twenty's file storage and linked to the Opportunity. Original create timestamps and note authors are preserved in custom fields on the Note record.
Gearbox
Service History Line Items
Twenty CRM
Note on Opportunity
1:1Gearbox work order line items (parts used, labor hours, external costs) have no native equivalent in Twenty Opportunities. FlitStack preserves this data as a formatted Note attached to the Opportunity, including a plain-text breakdown of parts and costs, so the financial history of the work order is not lost even though it cannot be rendered as structured fields.
Gearbox
Inventory / Parts
Twenty CRM
Custom Object: Part (optional)
1:1Gearbox inventory and parts catalog records may be migrated as a custom Part object in Twenty if the team wants to link parts to work orders. This requires a separate mapping pass and is scoped as optional depending on whether parts linkage drives reporting in Twenty.
Gearbox
Gearbox Custom Fields
Twenty CRM
Twenty Custom Fields
1:1Any Gearbox custom fields on Contractor, Company, Work Order, or Vehicle records require pre-creation in Twenty via Settings → Data Model before the CSV import runs. FlitStack delivers a custom field creation plan as part of the pre-migration schema review so the Twenty admin can provision fields before the import begins.
Gearbox
Gearbox User Role
Twenty CRM
Workspace Member Role
1:1Gearbox role-based permissions (Admin, Technician, Viewer) do not have a direct equivalent in Twenty's permission model. FlitStack does not migrate access-control configurations. The Twenty admin configures Workspace Member roles and object-level permissions after migration based on the organization's desired access map.
Gearbox
Gearbox Association Labels
Twenty CRM
Opportunity Contact Role
1:1If Gearbox tracks which contractor is the primary contact for a work order, FlitStack maps that label to an Opportunity Contact Role in Twenty. Standard labels (Primary Contact, Billing Contact) translate to built-in Twenty contact roles. Non-standard labels are preserved as a custom Select field on the Opportunity's person relation.

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.
Gearbox gotchas
Gearbox edition tiers gate API access
Work order history links assets by ID, not UUID
Preventive maintenance schedules use interval math that varies by platform
Contractor records may be soft-deleted in Gearbox
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 Gearbox data model and export all entities
FlitStack AI connects to Gearbox via its REST API using read-only scoped credentials. We export all Contractor, Company, Work Order, Vehicle, and Task records in parallel, preserving original creation timestamps, assignment history, and any Gearbox custom field values. A data quality report flags records with missing required fields, duplicate entries, and orphaned foreign keys before we design the mapping plan.
Design and validate the Twenty target schema
We review Twenty's current data model and create a schema setup plan: the Vehicle custom object, custom fields on People and Opportunities, and any required Workspace Members. The Twenty admin provisions fields and invites team members before the import begins. We validate that all required fields exist in Twenty before any records are loaded. We run a dry-run import against a test workspace to confirm field types match, relation fields resolve correctly, and the import order produces no referential integrity errors before committing to the production workspace.
Resolve Gearbox users to Twenty Workspace Members by email
Gearbox work order assignments are resolved by matching Gearbox user emails against Twenty Workspace Members. Unmatched users are flagged before migration — the Twenty admin invites them first or assigns records to a fallback member. No opportunity lands without a valid Twenty assignee. Gearbox users who are also contractors are handled as dual-role People records with a Workspace Member link. When multiple Gearbox users share the same email domain, we verify the name and role fields to disambiguate and prevent accidental contact merging during import.
Import in load-order sequence: Companies → People → Vehicles → Opportunities
Twenty enforces referential integrity — Companies must exist before People can link to them, and Vehicles must exist before Opportunities can reference them. We import Companies first (using domain as the unique identifier), then People with their CompanyId links, then Vehicle custom object records, then Opportunities with their Company, Vehicle, and assignee lookups resolved. Each batch is validated against Twenty's API before the next begins.
Run sample migration with field-level diff before full commit
A representative slice — typically 100–300 records spanning contractors, companies, work orders, and vehicles — migrates first. FlitStack AI generates a field-level diff between the Gearbox source and the Twenty destination so you can verify custom field mapping, Vehicle relation resolution, and opportunity stage assignment before the full run commits. Any mapping errors are corrected before the final migration begins. The sample diff covers all object types and relationship cardinalities to ensure the transformation logic handles edge cases such as null values, multi-word stage names, and vehicles with no linked work orders.
Full migration with delta pickup and post-import verification
The full migration runs against Twenty's API with rate-limit-aware batching. A delta-pickup window (typically 24 hours) captures any Gearbox records created or modified during the cutover window so Twenty reflects Gearbox's final state at go-live. We verify record counts per object, spot-check relationship integrity (People → Company links, Opportunity → Vehicle links), and run a final audit log review. One-click rollback is available if reconciliation reveals data integrity issues.
