Overview
Field Nexus organizes data around field-service operations: contacts, companies, work orders, invoices, estimates, and team members with scheduling and dispatch capabilities. HighLevel models data around CRM relationships: Contacts, Companies, Opportunities, Tasks, and Custom Objects with an integrated marketing automation layer. These data models overlap at Contacts and Companies but diverge everywhere else — Field Nexus work orders have no native HighLevel equivalent, Field Nexus invoices require migration as custom objects, and Field Nexus automations cannot transfer to HighLevel's workflow builder. FlitStack AI reads Field Nexus via its REST API, maps each object to its HighLevel counterpart, creates any needed custom fields on HighLevel's Custom Objects, and writes via HighLevel's Contacts/Companies API and Custom Objects API. A delta-pickup window captures any records modified during the cutover window. All automations, scheduling rules, and dispatch logic must be rebuilt in HighLevel's Workflows feature after migration — we provide a field-export audit of your current automations as a rebuild reference. Invoices migrate as a custom object with line items flattened into a JSON or text field since HighLevel has no native billing object.
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 Field Nexus object lands in HighLevel, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Field Nexus
Contact
HighLevel
Contact
1:1Field Nexus contacts map directly to HighLevel contacts. Email, phone, name, and address fields transfer 1:1. HighLevel's Contact object requires a CompanyId lookup — contacts without a primary company in Field Nexus are attached to a default placeholder company or flagged for manual assignment.
Field Nexus
Company
HighLevel
Company
1:1Field Nexus company records map to HighLevel companies through a direct field-to-field transfer. Company name, website, phone number, industry classification, and physical address fields migrate to their corresponding HighLevel company fields. Any Field Nexus company properties that lack a direct HighLevel standard field equivalent are identified during the pre-migration audit and created as custom fields on the Company object before the migration run begins.
Field Nexus
Work Order
HighLevel
Custom Object: Work Order
1:1Field Nexus work orders have no native HighLevel equivalent — they are migrated as a HighLevel Custom Object. We create a Work_Order__c custom object with custom fields for job status, scheduled date, assigned team member, job description, and source system ID. The custom object is linked to the migrated Contact and Company records via relationship fields.
Field Nexus
Invoice
HighLevel
Custom Object: Invoice
1:1Field Nexus invoices migrate as a HighLevel Custom Object (Invoice__c). Invoice line items are serialized into a JSON custom field or stored as a text blob since HighLevel has no native billing object. We preserve invoice number, status, issue date, due date, total amount, and the Contact/Company link.
Field Nexus
Estimate
HighLevel
Custom Object: Estimate
1:1Field Nexus estimates (quotes) migrate as a Custom Object (Estimate__c). Estimate status (draft, sent, accepted, rejected) maps to a custom pick-list field. Line items are serialized as with invoices. The Estimate__c custom object is linked to the Contact and Company custom objects for relationship continuity.
Field Nexus
Team Member
HighLevel
User
1:1Field Nexus team members are resolved by email against HighLevel users. Matched users are assigned as owners on migrated records (Contacts, Companies, Work_Order__c, Invoice__c). Unmatched team members are flagged before migration — your team either creates HighLevel user accounts first or assigns their records to a fallback owner.
Field Nexus
Contact Custom Properties
HighLevel
Contact Custom Fields
1:1Any Field Nexus contact property that does not map to a standard HighLevel contact field is migrated as a custom field on the Contact object. Custom field type is inferred from the source data type (text, number, date, pick-list). Custom field names in HighLevel use the source property name with underscores replacing spaces.
Field Nexus
Company Custom Properties
HighLevel
Company Custom Fields
1:1Field Nexus company properties that lack a HighLevel standard field equivalent are systematically migrated as custom fields on the Company object. Numeric properties such as years in business, number of technicians on staff, annual service call volume, and similar quantitative metrics are created as number fields. Free-text properties including internal account notes, billing terms, and custom classification tags are migrated as text fields. The custom field creation checklist identifies each source property, its data type, and the corresponding HighLevel field type before migration.
Field Nexus
Activity History (calls, notes, emails)
HighLevel
Task / Note
1:1Field Nexus call logs and notes map to HighLevel Tasks with Type set to 'Call' or 'Note'. Original timestamps and assigned team members are preserved. Emails logged in Field Nexus map to Tasks with Type='Email'. All activity tasks are linked to the parent Contact record in HighLevel.
Field Nexus
Job Scheduling / Dispatch Data
HighLevel
Custom Object: Work Order (scheduling fields)
1:1Field Nexus scheduling data (job start/end times, dispatch status, assigned technician) migrates into the Work_Order__c custom object's custom fields. HighLevel's calendar and appointment features are separate — the scheduling data is preserved for reference but the dispatch workflow must be rebuilt using HighLevel's Workflows feature.
Field Nexus
Payment Records
HighLevel
Invoice__c Custom Object (payment status field)
1:1Field Nexus payment records update the status field on the migrated Invoice__c custom object (from 'unpaid' to 'paid') rather than creating separate payment transaction objects. The original payment date and amount are stored in custom fields on the Invoice__c record.
Field Nexus
Attachments / Photos
HighLevel
Contact / Company Custom Object Attachments
1:1Field Nexus file attachments and job photos are downloaded from the source platform and re-uploaded to HighLevel's file storage, linked to the relevant Contact, Company, or Work_Order__c record using the Source_System_ID__c reference. File size limits per HighLevel's storage configuration apply and are checked before re-upload. Inline images embedded within notes are extracted, downloaded separately, and rehosted within HighLevel's file storage to maintain visual context in the migrated record history.

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
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Audit Field Nexus data model and generate custom field creation plan for HighLevel
FlitStack AI connects to Field Nexus via its REST API and exports a full inventory of all object types, standard fields, and custom properties. We cross-reference this against HighLevel's standard field names and identify every custom field that must be created before migration. We generate a custom field creation checklist organized by object (Contact, Company, Work_Order__c, Invoice__c, Estimate__c) with field type, pick-list values, and required/optional status. You or your HighLevel admin create these fields in your sub-account before we proceed to the test migration. This step also identifies work order relationships to contacts and companies so the sequencing (contacts first, then companies, then work orders) is enforced.
Resolve Field Nexus team members to HighLevel users by email
Field Nexus team members are the assigned owners of work orders, contacts, and companies. FlitStack AI matches Field Nexus team member email addresses against HighLevel user accounts in your sub-account. Matched users are assigned as owners on migrated records. Unmatched team members are flagged in a pre-migration report — your team either creates HighLevel user accounts for them before migration or designates a fallback owner. No record migrates without a resolvable owner; orphan records are held and reported rather than written with null owners.
Run a sample migration of 100–500 records with field-level diff
A representative slice of contacts, companies, work orders, and invoices migrates to your HighLevel sub-account first. We generate a field-level diff report comparing source Field Nexus values against the written HighLevel values for every mapped field. You verify that work order custom objects link correctly to their parent contacts and companies, that invoice line items are readable in the JSON field, that owner resolution is correct, and that custom field values landed as expected. Approval of the sample diff is required before the full migration commits. Any field mapping that needs adjustment is corrected before the full run.
Execute full migration with object sequencing and delta-pickup window
The full migration runs in object dependency order: Companies first (required for Contact.CompanyId), then Contacts, then Work_Order__c and Invoice__c custom objects with their relationship fields resolved via the Source_System_ID__c lookup chain. A delta-pickup window of 24–48 hours opens simultaneously — any Field Nexus record created or modified during the migration run is captured in a second pass after the initial batch completes. All operations are logged to an audit log. One-click rollback reverts all migrated records if reconciliation identifies data integrity issues.
Deliver reconciliation report and automation rebuild reference
Post-migration, FlitStack AI generates a reconciliation report showing record counts by object, any records that failed to migrate with error reasons, owner resolution summary, and a field-level validation summary. We deliver the Field Nexus automation configuration export as a structured rebuild reference for your HighLevel admin. Post-migration support is available for 10 business days to address any record-level issues discovered during go-live verification.
