Overview
Moving from Sunbase Data to GoHighLevel is a structural migration that crosses two different data models. Sunbase Data organizes contractor operations around Leads, Contacts, Clients, Deals, Projects, Work Orders, and Invoices distributed across separate CRM, project management, and financial modules. GoHighLevel uses a unified Contact model with pipeline Deals, an appointments calendar, and a tasks-and-activities system. Sunbase Data has no publicly documented REST API, which means data extraction relies on direct database access (enterprise) or per-module CSV exports, and we must coordinate with Sunbase's technical team during discovery to establish an extraction method. We preserve cross-record relationships by building a relationship map during discovery that links Contact IDs to Deal IDs, Project IDs to Work Order IDs, and Employee IDs to scheduling records. We do not migrate Sunbase automation workflows, pipeline board configurations, or custom object definitions; these are documented in a written handoff for the customer's admin to rebuild in GoHighLevel's workflow builder. Projects, Work Orders, and Invoices from Sunbase's project and financial modules migrate as GoHighLevel Custom Objects or tagged notes with external reference IDs, because GoHighLevel does not have a native project or work-order record type at the Starter and Unlimited tiers.

Object mapping
Each row shows how a Sunbase Data 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.
Sunbase Data
Lead
HighLevel
Contact (Lead source)
1:1Sunbase Leads capture unqualified prospects from door-to-door sales forms, web capture, and manual entry. We map Sunbase Lead records to GoHighLevel Contact records with the lead_source field set to the Sunbase lead source value. Lead status and assignment data migrate as custom fields on the Contact record. Leads tied to Sunbase automation workflows are documented separately; the automation logic is not migratable and requires rebuild in GoHighLevel's workflow builder.
Sunbase Data
Contact
HighLevel
Contact
1:1Sunbase Contact records include standard fields (name, email, phone, address) plus industry-specific fields depending on CRM module configuration. We map each Contact to GoHighLevel Contact, preserving the full name, email, phone, and address fields. Any Sunbase custom fields require a manifest from the customer during scoping because Sunbase does not export field definition metadata. GoHighLevel's custom fields accommodate most Sunbase contact extensions.
Sunbase Data
Deal
HighLevel
Opportunity (Pipeline Deal)
1:1Sunbase Deals track the sales cycle including proposals, quotes, and pipeline stages. We map Deals to GoHighLevel Opportunities with the deal value, stage name, and associated contacts. Sunbase's pipeline stage names migrate as GoHighLevel pipeline stage values. Custom deal fields require explicit mapping during scoping. The deal's associated Contact links via GoHighLevel's Contact-Opportunity relationship.
Sunbase Data
Pipeline Stage
HighLevel
Pipeline Stage
lossySunbase pipeline configurations (stage names, board positions) migrate as data values in GoHighLevel. We create a GoHighLevel custom pipeline before migration and populate stage names to match Sunbase's board. The visual drag-and-drop layout cannot be reproduced programmatically; we document the original layout for the customer's admin to reconfigure manually in GoHighLevel's pipeline editor.
Sunbase Data
Project
HighLevel
Custom Object or Tagged Notes
1:manySunbase Projects represent installation or job-site operations with metadata, status, budget tracking, and linked work orders. GoHighLevel does not have a native project record type. We migrate Projects as GoHighLevel Custom Objects (available on Starter $97/mo and above) with fields for project name, status, budget, and an external_project_id reference back to the Sunbase record. If the customer's GoHighLevel tier does not support Custom Objects, we create a tagged note attached to the associated Contact or Opportunity with project details.
Sunbase Data
Work Order
HighLevel
Custom Object or Task
1:manySunbase Work Orders include permit info, task details, attachments, and system specifications. We map Work Orders to GoHighLevel Custom Objects with fields for permit info, task details, and system specifications. Linked employee assignments and scheduling data map to GoHighLevel Tasks or Appointments. Attachments migrate as GoHighLevel documents attached to the Custom Object or parent Contact record.
Sunbase Data
Invoice
HighLevel
Custom Object (Invoice)
1:1Sunbase Invoices include line items, payment status, and linkage to the originating project or client. We map Invoices to GoHighLevel Custom Objects with invoice number, line items, total amount, payment status, and a linked Contact. Historical paid invoices migrate with their full detail. If GoHighLevel Payments is enabled on the destination account, we link Invoice records to GoHighLevel Payment records where applicable.
Sunbase Data
Client
HighLevel
Contact or Account
1:1Sunbase Client records represent contracted customers distinct from Leads and Contacts. We map Client records to GoHighLevel Contact records (for individual clients) or create a GoHighLevel Contact with a company flag for business clients. The mapping choice depends on whether the customer uses GoHighLevel's account model or manages all relationships at the Contact level.
Sunbase Data
Employee
HighLevel
User
1:1Sunbase Employee records include HR data, crew assignments, and role metadata. We map Sunbase Employees to GoHighLevel Users for team members who need CRM access. GPS location history and crew assignment data migrate as custom fields on the User record or as linked Custom Object records. External-only employees (no CRM login needed) migrate as Contacts with an employee_flag custom field.
Sunbase Data
Appointment
HighLevel
Appointment
1:1Sunbase Appointments include customer-linked scheduling, date, time, assigned contact, and status. We map Appointments to GoHighLevel Appointments with the calendar date, time, assigned Contact, and status preserved. Sunbase's Google Calendar sync linkage is not transferable; appointments migrate as new GoHighLevel calendar entries. Any appointment notes or details map to the GoHighLevel Appointment description field.
Sunbase Data
Document
HighLevel
Document (file attachment)
1:1Sunbase Documents include contracts, financing applications, and permits stored within the platform. We extract binary files and preserve file names, upload dates, and associations to the parent record (Contact, Deal, Project). Documents attach to the mapped GoHighLevel record (Contact, Opportunity, or Custom Object) via GoHighLevel's file attachment mechanism. Large file attachments may require additional scoping if storage limits on the destination GoHighLevel plan are constrained.

Sunbase Data gotchas
No publicly documented REST API or export endpoints
Module-level data isolation complicates bulk exports
Automation workflows and pipeline configurations are non-exportable
Custom fields lack a schema definition 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
Discovery and extraction method confirmation
We audit all active Sunbase Data modules (CRM, project management, HR, financial) and confirm the extraction method with Sunbase's technical team. For enterprise migrations, this means coordinating direct database access. For standard migrations, we plan per-module CSV exports and build the cross-module relationship map that connects Contact IDs to Deal IDs, Project IDs to Work Order IDs, and Employee IDs to appointment records. We also confirm the GoHighLevel destination account, tier, and any Custom Object entitlements before proceeding.
GoHighLevel schema design and Custom Object provisioning
We design the destination schema in GoHighLevel. This includes creating Custom Objects for Projects and Work Orders (if applicable), adding custom fields to Contact and Opportunity to capture Sunbase-specific data, and configuring pipeline stages to match Sunbase's deal board. We deploy Custom Object schema into the GoHighLevel account before any data import. The customer's admin reviews and approves the schema design during this phase.
Data extraction, relationship mapping, and staging
We extract data from Sunbase using the confirmed method. For each module, we produce a structured CSV or database export and apply the cross-module relationship map we built during discovery. We create a staging environment or sandbox migration first, importing Contacts, then Deals (with Contact links resolved), then Projects and Work Orders as Custom Objects, then Employees as Users or Contacts, then Appointments. Each phase emits a row-count reconciliation report before the next phase begins.
Sandbox migration and reconciliation
We run a full migration into a GoHighLevel staging environment using production-like data volume. The customer's operations lead reconciles record counts (Contacts in, Deals in, Projects in, Work Orders in, Employees in, Appointments in), spot-checks 25-50 random records against the Sunbase source, and reviews the relationship integrity (Deal-to-Contact links, Project-to-Work Order links). Any mapping corrections happen here, not in production.
Production migration in dependency order
We run production migration in record-dependency order: Contacts (first, as the primary record), then Deals with Contact lookups resolved, then Projects and Work Orders as Custom Objects, then Employees, then Appointments. Documents attach to parent records during or after migration depending on volume. We freeze Sunbase writes during cutover and run a final delta migration of any records modified during the migration window.
Cutover, validation, and automation handoff
We enable GoHighLevel as the system of record after the final delta sync. We deliver the automation workflow inventory document to the customer's admin team documenting every Sunbase automation with its trigger, conditions, and actions, plus a recommended GoHighLevel workflow equivalent. We support a one-week hypercare window where we resolve reconciliation issues. We do not rebuild Sunbase automations as GoHighLevel workflows inside the migration scope; that is a separate engagement.
