Overview
Field Nexus organizes data around field-service operations: clients, work orders, estimates, invoices, and technician scheduling. HubSpot CRM organizes around leads, contacts, companies, and deals with a marketing-and-sales lifecycle model. These models diverge structurally — Field Nexus work orders don't map to any single HubSpot object; instead, they decompose into a Deal for the job scope, associated Contact/Company records, and optional custom objects for equipment or service-line metadata. HubSpot's Deals carry a pipeline and stage model that captures job progress; HubSpot's lifecycle_stage on contacts tracks customer status; and HubSpot's Tickets object (Service Hub) can surface post-sale service requests. The migration carries your contacts, companies, work orders, estimates, invoices, and custom fields via HubSpot's Bulk API and CRM import tools. Workflows, automation rules, and field-service scheduling logic in Field Nexus do not migrate — those must be rebuilt using HubSpot's Workflows and Sequences tools after go-live. FlitStack AI sequences the migration so foreign-key relationships resolve correctly: contacts require their parent companies to land first, and work orders require their associated contacts before Deal creation.

Object mapping
Each row shows how a Field Nexus object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Field Nexus
Client
HubSpot
Contact
1:1Field Nexus client records map directly to HubSpot Contacts. Client name splits into HubSpot firstname and lastname where available; otherwise the full name populates FirstName and LastName remains blank. Client email, phone, and address fields map to HubSpot's corresponding standard properties. Primary company association migrates as a Contact-Company association.
Field Nexus
Client Company
HubSpot
Company
1:1If Field Nexus stores client business names separately from individual contacts, those map to HubSpot Companies. Company name, domain/website, industry, and employee-count fields map to their HubSpot equivalents. HubSpot Companies can have multiple associated contacts — we preserve the N:1 or 1:1 relationship from Field Nexus.
Field Nexus
Work Order
HubSpot
Deal
1:1Field Nexus work orders decompose into HubSpot Deals. The work order title becomes Deal name; estimated or final job amount becomes Deal amount; work-order status (Scheduled, In Progress, Completed, Cancelled) maps to a HubSpot Deal pipeline stage via value mapping. The client contact becomes the primary Deal contact via Opportunity Contact Role.
Field Nexus
Work Order Status
HubSpot
Deal Stage
1:1Each Field Nexus status value maps to a corresponding HubSpot pipeline stage. Scheduled → Appointment Scheduled; In Progress → Working; Completed → Closed Won; Cancelled → Closed Lost. Custom status values require HubSpot admin to pre-create pipeline stages before migration runs. Stage-entered timestamps are preserved as custom datetime fields.
Field Nexus
Estimate / Quote
HubSpot
Deal (with Proposal Sent)
1:1Field Nexus estimates map to HubSpot Deals with a pre-populated Deal name and amount. If the estimate has been sent to the client, we flag it as 'Proposal Sent' in a custom field and set HubSpot Deal stage accordingly. Estimate line items become a custom field or are stored as a multi-line text property for reference.
Field Nexus
Invoice
HubSpot
Custom Object or Line-Item Property
1:1HubSpot has no native invoice object in Sales Hub. Field Nexus invoices migrate as a custom object (Invoice__c) with fields for invoice number, amount, status, and associated Deal. For simpler setups, invoice reference data stores as properties on the parent Deal. Payment status is preserved; actual payment recording requires HubSpot Payments or a connected accounting tool.
Field Nexus
Technician / Staff
HubSpot
HubSpot Owner
1:1Field Nexus technician and staff records map to HubSpot Owners. Resolution is by email — each Field Nexus user email matches against HubSpot user email. Unmatched users are flagged before migration; the team either creates HubSpot users first or assigns records to a fallback owner. Active/inactive status on the technician maps to HubSpot user active flag.
Field Nexus
Equipment / Asset
HubSpot
Custom Object
1:1Field Nexus equipment records do not have a HubSpot native equivalent. We create a custom object (Equipment__c) with fields for asset name, serial number, location, and service-history notes. Equipment is associated to the relevant Contact or Company via a custom lookup relationship field.
Field Nexus
Service History / Activity Log
HubSpot
Engagements (Emails, Calls, Notes)
1:1Field Nexus work-order activity history (status changes, technician notes, customer sign-offs) migrates as HubSpot Engagements. Timestamps, technician owner, and the activity description are preserved. These surface in HubSpot's contact and deal timelines. Rich-text formatting in notes migrates as plain text to avoid rendering issues.
Field Nexus
Custom Fields (Work Order)
HubSpot
Custom Properties on Deal
1:1Field Nexus custom fields on work orders (e.g., service type, priority level, dispatch zone) map to HubSpot custom properties on the Deal object. We create these as HubSpot custom properties during migration setup. Field type parity is maintained where possible — pick-lists become HubSpot option sets, number fields become number properties.
Field Nexus
Custom Fields (Client)
HubSpot
Custom Properties on Contact
1:1Field Nexus custom fields on client records (e.g., customer tier, preferred contact method, referral source) map to HubSpot Contact custom properties. Same field-type translation rules apply as with work orders. If the custom field is a reference to another object (e.g., linked equipment), we create a corresponding custom object in HubSpot with a lookup relationship.

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.
Field Nexus gotchas
No documented API — migration requires manual web exports
No published pricing — upgrade path and tier limits unknown
Payment link references may not survive schema translation
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Audit Field Nexus data model and identify migration scope
FlitStack AI reads your Field Nexus export — contacts, companies, work orders, estimates, invoices, and any custom fields on those objects. We identify records with missing required fields, duplicate entries, and broken foreign-key relationships (e.g., work orders referencing clients that don't exist). The audit report tells you what to clean up before migration and what HubSpot tier you'll need for custom object support.
Create HubSpot custom objects and properties before data lands
Before any data moves, FlitStack creates the custom properties and custom objects your migration requires: Deal custom fields for service type and priority, the Invoice__c object, and the Equipment__c object with its association definitions. We deliver a HubSpot setup checklist so your admin can pre-create pipeline stages, pick-list values, and any custom object associations at the appropriate tier level. This checklist also specifies required field types, validation rules, and default values to ensure the custom objects are ready for data loading without post-migration edits.
Resolve technician users and client-company relationships
FlitStack matches Field Nexus technicians to HubSpot users by email. Unmatched technicians are flagged for your team to create as HubSpot users or assign to a fallback owner. We also identify whether Field Nexus clients store individual contacts separately from their company — if so, we create HubSpot Company records first, then associate Contact records to them before work orders reference those contacts.
Run a sample migration with field-level diff on 100–500 records
A representative slice migrates first — typically 100–500 records spanning contacts, companies, work orders, estimates, and a few invoices. We generate a field-level diff showing every source field value alongside its destination field value so you can verify that status-to-stage mapping, owner resolution, and custom object associations are correct before the full run commits. The diff also flags any missing required fields, mismatched data types, and potential duplicate records, allowing your team to correct source data before proceeding.
Execute full migration with delta-pickup window and audit log
The full migration runs against your HubSpot portal. A delta-pickup window (typically 24–48 hours) captures any Field Nexus records created or modified during cutover so HubSpot reflects the final state at go-live. FlitStack maintains an audit log of every operation — creates, updates, skips, and errors — with one-click rollback available if reconciliation fails. Each record's migration timestamp and status are recorded, enabling you to trace any unexpected behavior back to its source event.
Deliver reconciliation report and workflow-rebuild reference
After migration, FlitStack delivers a record-count reconciliation report comparing Field Nexus totals against HubSpot totals by object. Any records that skipped or errored are listed with the reason. We also export your Field Nexus workflow definitions as a rebuild reference document so your HubSpot admin can reconstruct dispatch and notification automations in HubSpot Workflows. The report includes a summary of data quality metrics, such as duplicate detection rates and missing mandatory field percentages, to support ongoing data hygiene efforts.
