Overview
Fergus is a field-service management platform built for trade businesses — plumbers, electricians, HVAC contractors — to manage jobs, quotes, materials, and invoices. Its data model centers on Customers, Jobs, Quotes, Invoices, and Pricing Tiers, with scheduling and staff assignment built around job phases. HighLevel is a CRM and marketing automation platform built for agencies and service businesses; its data model centers on Contacts, Companies, Opportunities (with customizable pipeline stages), Workflows, Tasks, and Appointments. Fergus has no native lead or opportunity concept — deals are embedded in Jobs with quote and invoice states. HighLevel has no native job-management or materials-tracking objects — those require custom fields on Opportunities or Contacts. We map Fergus Customers to HighLevel Contacts (and optionally Companies), Jobs to HighLevel Opportunities with custom fields for materials and phase status, Quotes to Opportunities with stage-based deal tracking, Invoices to Opportunities with a custom invoice-status field, and Pricing Tiers to custom pick-list fields on Contacts or Opportunities. Fergus API rate limits (100 requests per minute per company) govern our export cadence; we batch reads and paginate to avoid 429 responses. Workflows, automations, SMS sequences, and email templates do not migrate — they require a rebuild using HighLevel's Workflow Builder. We deliver a field-level migration plan, run a sample pass with diff, and apply a delta-pickup window (24–48 hours) before finalizing so no in-flight jobs are missed.

Object mapping
Each row shows how a Fergus 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.
Fergus
Customer
HighLevel
Contact + Company
many:1Fergus Customers map to both a HighLevel Contact and a HighLevel Company. The contact holds the primary person record (name, phone, email); the company holds business-level data (business name, address). Staff and trade contacts within Fergus become separate Contact records linked to the primary Company.
Fergus
Customer Phone / Email
HighLevel
Contact Phone / Email
1:1Fergus stores phone and email as standard contact properties. HighLevel maps these to its native Contact fields during migration, preserving all contact identifiers across systems. If a Fergus customer has multiple phone numbers on file, the additional numbers are created as custom fields on the HighLevel Contact record to preserve the complete contact profile.
Fergus
Job
HighLevel
Opportunity
1:1Fergus Jobs map to HighLevel Opportunities. Job status (New, In Progress, Scheduled, Completed, Invoiced) maps to a custom Opportunity stage or a custom pick-list field (Job_Status__c) on the Opportunity. Job phases map to custom fields or Opportunity-level notes capturing each phase's status and timestamp.
Fergus
Job Phase
HighLevel
Opportunity Custom Field (Phase__c)
1:1Fergus Jobs contain named phases (e.g., Survey, Materials Ordered, Installation, Inspection). HighLevel has no native phase concept. We create a custom multi-select or pick-list field Phase__c on the Opportunity and populate it from Fergus phase names. Phase sequence and timestamps are preserved in Phase_History__c as a text audit trail.
Fergus
Quote / Estimate
HighLevel
Opportunity (Quote Sent stage)
1:1Fergus Quotes are distinct from Jobs. Each Quote migrates as a separate Opportunity record in a 'Quote Sent' stage (or a custom 'Quote' stage your admin creates). Line-item details (materials, labour rates) are stored as a JSON-formatted note on the Opportunity since HighLevel lacks native quote line items.
Fergus
Invoice
HighLevel
Opportunity (Invoiced stage) + custom field Invoice_Status__c
1:1Fergus Invoices have a lifecycle separate from Jobs. We create a custom field Invoice_Status__c on the Opportunity (values: Sent, Paid, Overdue, Void) and migrate invoice records as Opportunity records in an 'Invoiced' stage. The original invoice number and total are stored in custom fields on the Opportunity.
Fergus
Pricing Tier
HighLevel
Contact Custom Field (Pricing_Tier__c)
1:1Fergus Pricing Tiers are customer-level pricing rules. These map to a custom pick-list field Pricing_Tier__c on the HighLevel Contact. Tier values (e.g., Trade Standard, Preferred, Wholesale) are recreated as pick-list options. Material-specific pricing within tiers is stored as a text custom field for reference.
Fergus
Material / Line Item
HighLevel
Opportunity Custom Field (Materials_List__c)
1:1Fergus material line items within Jobs have product name, quantity, unit price, and total. HighLevel has no native line-item object. We store material summaries as a text field Materials_List__c on the Opportunity, formatted as a readable list. Detailed line-item accounting remains in your accounting tool (Xero/QuickBooks) post-migration.
Fergus
Staff / Assigned Technician
HighLevel
HighLevel User (by email match)
1:1Fergus staff records contain name, email, and role information. We match Fergus staff by email to HighLevel User accounts using an automated lookup process. Any staff members without a matching HighLevel User are flagged as Contacts with a custom field Staff_Source__c, allowing you to manually invite them to HighLevel before migration finalization.
Fergus
Job Note / Attachment
HighLevel
Contact / Opportunity Note
1:1Fergus job notes migrate as HighLevel Notes attached to the corresponding Opportunity record. All file attachments such as photos, diagrams, and PDFs are re-uploaded to HighLevel Files and linked to the Opportunity. Original timestamps and author names are preserved within the note metadata for audit continuity.
Fergus
Tag / Label
HighLevel
HighLevel Tag
1:1Fergus does not have a native tagging system, but any custom labels your team applied to Jobs or Customers migrate as HighLevel Tags on the relevant Contact or Opportunity record. Tags are flat — no hierarchical tag structure is needed.
Fergus
Custom Field (Fergus)
HighLevel
Custom Field (HighLevel Contact or Opportunity)
1:1Fergus custom fields on Customers and Jobs map to HighLevel custom fields on Contact or Opportunity depending on object. HighLevel requires you to choose Contact vs Opportunity at field creation — we verify object assignment during the mapping plan phase. Field type mapping: text → text, number → number, date → date, pick-list → pick-list.

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.
Fergus gotchas
100 req/min API rate limit constrains bulk exports
Customer pricing tier data requires explicit mapping
Quote and invoice warning badges are state-dependent
No documented public schema for custom fields
Job photos and attachments require separate file export
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 Fergus data volume and custom field inventory
We connect to Fergus via API with read-only credentials and enumerate all Customers, Jobs, Quotes, Invoices, staff records, and custom fields. We count records per object, identify empty or deprecated custom fields, and check for inactive jobs or archived records. This audit generates the migration scope document: record counts, custom field list, pricing tier inventory, and any data-quality flags (missing emails, duplicate customers) that need resolution before migration.
Design HighLevel custom field schema in your sub-account
Your HighLevel admin (or our team) creates the custom fields we specified in the mapping plan — Job_Status__c, Phase__c, Phase_History__c, Materials_List__c, Invoice_Number__c, Invoice_Status__c, Pricing_Tier__c, Original_Create_Date__c, Source_System_ID__c — as Contact and/or Opportunity custom fields. We deliver the exact field names, types, and pick-list values so the schema is ready before any data lands. Staff accounts are invited to HighLevel so owner resolution by email succeeds.
Export Fergus data with rate-limit pacing and data-quality scrubbing
FlitStack AI pulls Fergus records in paginated batches, respecting the 100 req/min rate limit with exponential backoff on 429 responses. During export, we flag and optionally fix data-quality issues: contacts without email addresses, duplicate customers, jobs with no assigned staff. We export all objects in dependency order (Customers first, then Jobs, then Quotes and Invoices linked to jobs) so foreign-key resolution is clean on the destination side.
Run a sample migration with field-level diff
A representative slice — typically 100–500 records spanning customers, jobs, quotes, invoices, and staff assignments — migrates into HighLevel. We generate a field-level diff showing source value vs. destination value for every mapped field. You review the diff to verify pricing tier mapping, phase representation, and owner resolution. We adjust field mapping rules and re-run the sample until the diff is clean before committing to the full migration.
Execute full migration with delta-pickup window and audit log
The full dataset migrates into HighLevel. A delta-pickup window (24–48 hours after migration start) captures any Fergus records created or modified during the cutover — active jobs, new quotes, status changes. Every migration operation is logged to an audit trail. If reconciliation finds discrepancies, one-click rollback reverts the HighLevel environment to pre-migration state so you can investigate and re-run without data loss.
