Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

Leaving

Field Nexus

What's pushing teams away

  • Limited review footprint — the G2 profile has been inactive for over a year with no reviews, and App Store ratings are too sparse to display, making vendor due diligence harder.
  • No published pricing forces every prospect through a sales conversation, slowing comparison with transparent FSM competitors like Jobber or Housecall Pro.
  • API documentation is referenced as available 'for custom integrations' but no developer portal, endpoint reference, or authentication scheme is publicly published.
  • Concentrated regional footprint — the product is positioned for US and Canada operations, limiting fit for international service businesses.
  • Limited public marketing momentum and small social/community presence relative to category leaders raise concerns about long-term product investment for prospects evaluating five-year stacks.

Choosing

HighLevel logo

HighLevel

What's pulling them in

  • Agencies choose HighLevel to consolidate CRM, email, SMS, scheduling, and funnels into one subscription, eliminating monthly bills for five to ten separate SaaS tools they previously stitched together.
  • The flat-rate pricing model bills per sub-account rather than per contact, so growing a contact database from 1,000 to 100,000 records does not trigger a billing surprise—a common pain point avoided by migrating customers.
  • White-label and sub-account capabilities let agencies resell HighLevel access to their own clients, turning a software cost center into a recurring revenue stream that justifies the subscription.
  • The platform ships a 14-day free trial with no credit card required, giving teams a low-friction entry point to validate fit before committing to the $97/month Starter tier.
  • Marketing agencies managing multiple client accounts use sub-accounts to maintain data isolation per client while operating under a single agency billing relationship with HighLevel.

Object mapping

How Field Nexus objects map to HighLevel

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

maps to

HighLevel

Contact

1:1
Fully supported

Field 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

maps to

HighLevel

Company

1:1
Fully supported

Field 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

maps to

HighLevel

Custom Object: Work Order

1:1
Fully supported

Field 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

maps to

HighLevel

Custom Object: Invoice

1:1
Fully supported

Field 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

maps to

HighLevel

Custom Object: Estimate

1:1
Fully supported

Field 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

maps to

HighLevel

User

1:1
Fully supported

Field 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

maps to

HighLevel

Contact Custom Fields

1:1
Fully supported

Any 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

maps to

HighLevel

Company Custom Fields

1:1
Fully supported

Field 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)

maps to

HighLevel

Task / Note

1:1
Fully supported

Field 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

maps to

HighLevel

Custom Object: Work Order (scheduling fields)

1:1
Fully supported

Field 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

maps to

HighLevel

Invoice__c Custom Object (payment status field)

1:1
Fully supported

Field 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

maps to

HighLevel

Contact / Company Custom Object Attachments

1:1
Fully supported

Field 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.

Pair-specific challenges

  • Work orders have no native HighLevel equivalent — they require a custom object build before migration

    Field Nexus work orders bundle job status, scheduling, assigned technician, description, and customer link into a single operational record. HighLevel has no native work order or job object. FlitStack AI creates a Work_Order__c custom object with custom fields for each attribute before data lands — but the custom object definition must be created in your HighLevel sub-account first, and its relationship fields (ContactId, CompanyId) must resolve to records that exist already. This sequencing means companies and contacts migrate before work orders every time, and any mismatch in the foreign-key chain causes records to land without a parent link. We validate the entire relationship chain before committing the full migration run.

  • Field Nexus automations and dispatch rules do not migrate — HighLevel workflows must be rebuilt

    Field Nexus automation rules govern dispatch logic, job scheduling, and team assignment based on conditions. HighLevel's Workflows feature is a visual automation builder with triggers (Contact Created, Opportunity Stage Changed, Form Submitted) and actions (Send SMS, Add Tag, Create Task) — but it does not import Field Nexus automation definitions. Every dispatch rule, scheduling trigger, and notification workflow must be manually rebuilt in HighLevel's workflow builder. FlitStack AI exports your Field Nexus automation configuration as a structured reference document listing each rule's trigger condition, action, and field dependencies so your HighLevel admin can rebuild them in priority order. This is the largest post-migration effort for field-service teams.

  • Invoices migrate as custom objects with line items serialized — they are not native billing records

    HighLevel has no native invoice or billing object. Field Nexus invoices transfer as a custom object (Invoice__c) with line items stored as a JSON string in a long-text field (Line_Items_JSON__c). Invoice totals, status, and dates map to custom fields, but line-item granularity is not queryable inside HighLevel's standard reporting tools without a custom report type. If you rely on invoice data for revenue reporting or accounts-receivable tracking, plan to either build a custom report type on the Invoice__c object or export the JSON line items to a BI tool post-migration.

  • HighLevel API rate limits require migration to batch at up to 200,000 requests/day per sub-account

    HighLevel API 2.0 enforces a limit of 200,000 requests per day and 100 requests per 10 seconds per sub-account. Field Nexus exports with large work-order histories (thousands of records with multiple custom fields each) can exceed single-threaded migration speeds. FlitStack AI parallelizes writes within HighLevel's rate-limit envelope using the Bulk API for contacts and companies and the Custom Objects API for Work_Order__c and Invoice__c. We monitor 429 responses and back off automatically. Large migrations (over 200,000 records) may require extending the migration window beyond 48 hours to stay within rate-limit throttling.

  • Custom properties on Field Nexus contacts and companies require pre-migration custom field creation in HighLevel

    Field Nexus stores any non-standard contact or company property as a custom field on the standard object. HighLevel requires custom fields to be created before data can be written to them. FlitStack AI audits all Field Nexus custom properties before migration, generates a custom field creation checklist for your HighLevel sub-account, and creates the fields via the HighLevel Custom Objects API before writing records. If your Field Nexus account has more than 20 custom properties across objects, this pre-creation step extends planning time by 1–2 days. Any custom property added in Field Nexus after migration planning but before cutover requires a field-addition cycle before that data migrates.

Migration approach

Six steps for a successful Field Nexus to HighLevel data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

Destination

Strengths

  • Consolidates CRM, marketing automation, email, SMS, scheduling, and funnels into one platform at a predictable flat monthly rate.
  • Supports unlimited contacts and unlimited users on all paid tiers, removing per-record billing anxiety as databases grow.
  • Offers white-label and sub-account capabilities that let agencies resell access and manage multiple client environments under one billing relationship.
  • Includes built-in review management, reputation monitoring, and AI agents as native features rather than third-party add-ons.
  • Exports Contacts and Companies via a scalable async bulk CSV system that handles multi-million-row datasets without blocking the UI.

Weaknesses

  • The breadth of features creates a steep learning curve; advanced automations and Workflow configuration require significant time investment that smaller teams may not recover.
  • The platform charges usage-based fees for telecommunications and AI features that are not included in the base subscription, leading to bill surprises.
  • Recurring user reports on Reddit and G2 describe bugs, errors, and slow support response times that disrupt live marketing and sales operations.
  • Sub-account architecture, while powerful for agencies, adds migration complexity when identifying which client data lives in which isolated environment.
  • The platform is designed for agencies and SMBs; larger enterprises requiring deep reporting, custom objects at scale, or complex role-based access may outgrow its capabilities.

Most Field Nexus to HighLevel migrations complete within 48–72 hours for setups with fewer than 25,000 records. Larger datasets with extensive work-order history or more than 20 custom fields per object extend the timeline to 5–7 days. The pre-migration phase — auditing Field Nexus custom properties and creating corresponding HighLevel custom fields — adds 1–2 days and runs concurrently with your team's HighLevel configuration work. The delta-pickup window (24–48 hours) is the longest single phase for high-activity accounts.
