Overview
Moving from Gauss Box CRM & Sales to GoHighLevel is a migration from a European ERP-anchored CRM to an agency-focused all-in-one platform with stronger marketing automation. Gauss Box has no documented public API, so migration relies on CSV extraction coordinated with their support team; we use those CSVs as the source of truth. The most significant schema difference is that Gauss Box separates Leads, Persons, and Organizations, while GoHighLevel merges Persons and Organizations into a single Contact object with an optional Company field. We run the person-to-organization disambiguation during the transform phase, creating GoHighLevel Contacts with the parent company link resolved at import time. Deal and activity history migrate to GoHighLevel Opportunities and Tasks respectively. We do not migrate Gauss Box attribute-set configurations (custom fields) as code; we enumerate every custom attribute during discovery and document it as a GoHighLevel custom field creation checklist for the customer's admin before import. Workflows, automations, and document templates do not migrate and are delivered as written inventories for rebuild.
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 Gauss Box CRM & Sales 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.
Gauss Box CRM & Sales
Lead
HighLevel
Contact
1:1Gauss Box Leads map to GoHighLevel Contacts. In Gauss Box, Leads carry work status, assigned team member, and a link to a Person record. We extract the Lead's assigned Person contact details and create a single GoHighLevel Contact record using the Person's name, email, and phone. The Lead's work status and assigned team member map to GoHighLevel custom fields and Contact owner assignment respectively.

Person (Contact)
HighLevel
Contact
1:1Gauss Box Person records map directly to GoHighLevel Contacts. Name, email, phone, address, and any custom attribute fields migrate. If the Person is linked to an Organization in Gauss Box, we resolve the Organization as a GoHighLevel Company record and link the Contact to it via the CompanyId field during import.
Gauss Box CRM & Sales
Organization
HighLevel
Company
1:1Gauss Box Organization records map to GoHighLevel Company records. Organization name, industry, size, D&B data fields (if enriched), and address fields migrate. Organization is created before any linked Person or Deal import so that the Company relationship is satisfied at import time. D&B-specific fields that have no GoHighLevel equivalent become custom fields.
Gauss Box CRM & Sales
Deal
HighLevel
Opportunity
1:1Gauss Box Deals map to GoHighLevel Opportunities. Deal stage, owner, value, budget, and associated product links migrate. Pipeline stage names are account-specific in Gauss Box and require mapping to GoHighLevel pipeline stage names during discovery. The deal owner email resolves to a GoHighLevel team member by email match.
Gauss Box CRM & Sales
Activity
HighLevel
Task
1:1Gauss Box Activities (interactions linked to Deals and Contacts) map to GoHighLevel Tasks. Activity type, timestamp, description, and parent object link migrate. GoHighLevel does not have a separate meeting object; calendar events and meeting records from Gauss Box land as Tasks with a custom field activity_type__c set to 'Meeting'. Reminders embedded in parent Deal metadata are flagged as open reminder counts and documented separately for manual recreation.
Gauss Box CRM & Sales
Product
HighLevel
Product / Service
1:1Gauss Box Products (name, category, type, price, sale tax configuration) map to GoHighLevel Products and Services. We preserve the category, unit price, and tax configuration as GoHighLevel Product fields. Product-Deal associations stored in Gauss Box migrate as Opportunity Product line items in GoHighLevel.
Gauss Box CRM & Sales
Document
HighLevel
Attachment
1:1Gauss Box stores documents per record with access permissions. We extract files and re-attach them to the corresponding GoHighLevel Contact or Opportunity record. Filename and any stored metadata migrate. Access permission rules tied to Gauss Box user roles do not have a GoHighLevel equivalent and are documented as a permission model review item for the customer's admin post-migration.
Gauss Box CRM & Sales
Custom Attribute (Attribute Set)
HighLevel
Custom Field
lossyGauss Box attribute sets define custom fields per account on Contacts, Organizations, Deals, and Products. These are not standardized and require a mandatory discovery phase before mapping. We enumerate every active custom attribute, record its data type, and deliver a GoHighLevel custom field creation checklist organized by object. The customer creates these fields in GoHighLevel before the data import phase begins. Fields that exist only in Gauss Box (no equivalent in GoHighLevel standard schema) are flagged as custom fields requiring creation.
Gauss Box CRM & Sales
User Role and Assignment
HighLevel
Team Member
1:1Deals, Leads, and Activities carry owner assignments tied to Gauss Box user accounts. We extract every distinct owner email and match against GoHighLevel team member accounts. Owners without a matching GoHighLevel user are flagged in a reconciliation list for the customer's admin to provision before record import resumes. Owner email is the primary dedupe key.

Pair-specific challenges
Migration approach
CSV extraction coordination and discovery
We contact Gauss Box support on the customer's behalf to request a structured CSV export. We request separate exports for Organizations, Persons, Leads, Deals, Activities, and Products. Simultaneously, we enumerate every active attribute set in the Gauss Box account to build the custom field inventory. The customer provides Gauss Box login credentials and authorizes our access for the discovery phase. We deliver a CSV delivery checklist with expected record counts per object.
Custom field schema design in GoHighLevel
Using the Gauss Box attribute set inventory, we design the GoHighLevel custom field schema. We map each Gauss Box custom field to a GoHighLevel field type (text, number, date, picklist, checkbox) and group them by object (Contact, Opportunity, Product). We deliver a written custom field creation checklist organized by object so the customer's GoHighLevel admin creates the fields in the correct order before data import begins. This step gates the data import phase.
CSV transformation and pipeline stage mapping
We transform the Gauss Box CSVs into GoHighLevel-compatible import format. This includes splitting Gauss Box Leads and Persons into GoHighLevel Contacts, resolving Organization links to GoHighLevel Companies, mapping Gauss Box pipeline stage names to GoHighLevel pipeline stages, and transforming activity types into GoHighLevel Task records. Deal-Product associations are extracted into a separate association table for line-item creation after Opportunity import. Owner email addresses are resolved against GoHighLevel team members during this phase.
GoHighLevel import in dependency order
We import records into GoHighLevel in dependency order: Companies (first, as parent), Contacts (with CompanyId resolved), Opportunities (with ContactId and OwnerId resolved), Products, Opportunity Products (line items), and Tasks. Each phase emits a row-count reconciliation report. If record counts differ from the source CSV by more than a defined threshold, we pause and investigate before proceeding to the next phase.
Document attachment migration
We extract document files and metadata from Gauss Box, map each file to its migrated parent record (Contact or Opportunity), and re-attach them in GoHighLevel. Access permission rules from Gauss Box are documented in a separate permission model inventory and flagged for admin review in GoHighLevel.
Cutover, validation, and automation rebuild handoff
We freeze writes to the Gauss Box account during cutover, run a final delta export of any records modified during the migration window, and import the delta into GoHighLevel. We deliver a reconciliation report comparing source record counts to destination record counts and a written inventory of every Gauss Box workflow, reminder, and notification configuration for the customer's admin to rebuild in GoHighLevel's automation builder. We support a five-business-day hypercare window for post-migration reconciliation issues.
