Overview

What this migration involves

Moving from ZeyOS to GoHighLevel is a migration from a unified ERP/CRM/Groupware platform to a marketing-focused CRM built for agencies and service businesses. ZeyOS stores business data across Accounts, Contacts, Leads, Items, Projects, Tasks, Tickets, Contracts, and financial records in a PostgreSQL-backed system with a REST API that lacks a bulk endpoint. We paginate through ZeyOS records individually, handle audit-locked invoices by sequencing them in strict chronological order, and convert Unix epoch timestamps to ISO 8601 strings before GoHighLevel import. GoHighLevel uses Contacts as the primary person record with tag-based segmentation and pipeline-based opportunity management, which requires us to transform ZeyOS's project-centric task hierarchy into GoHighLevel's contact-centric workflow model. We do not migrate ZeyOS iXML scripts, ERP inventory transactions, or ZeyOS workflows as code; we deliver a written inventory of these for the customer's admin to rebuild in GoHighLevel's automation builder.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

ZeyOS logo

ZeyOS

What's pushing teams away

  • Very limited public review presence (only 1 verified G2 review, sparse Capterra coverage) makes it hard for prospective customers to gauge long-term reliability.
  • Smaller vendor footprint compared to Odoo, NetSuite, or HubSpot raises concerns about long-term product support and roadmap stability.
  • Custom iXML scripting layer adds development overhead for teams that want standard integrations without writing custom code.

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 ZeyOS objects map to HighLevel

Each row shows how a ZeyOS 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.

ZeyOS

Account

maps to

HighLevel

Contact (company field) + Location

1:1
Fully supported

ZeyOS Accounts map to GoHighLevel Contacts with the company name stored in the Contact's Company field and a GoHighLevel Location record created for address and phone data. The Location record preserves the ZeyOS account's primary address, billing address, and contact phone numbers. We use the account's external ID from ZeyOS as a custom GoHighLevel field for reconciliation after import.

ZeyOS

Contact

maps to

HighLevel

Contact

1:1
Fully supported

ZeyOS Contacts map directly to GoHighLevel Contacts with name, email, phone, and the parent Account link preserved via the Company field. The ZeyOS extdata fields (nickname, custom address fields) migrate as GoHighLevel custom properties with type inference from the ZeyOS fields table schema. Any ZeyOS Contacts without an email are flagged for manual review because GoHighLevel's import process requires an email or phone for deduplication.

ZeyOS

Lead

maps to

HighLevel

Contact (tagged as Lead)

1:many
Fully supported

ZeyOS Leads are a distinct object from Contacts and carry lead-specific status fields. We map ZeyOS Leads to GoHighLevel Contacts and apply a migration-specific tag (e.g., 'migrated-lead') plus the original ZeyOS lead status as a custom property. The customer decides during scoping whether to keep migrated Leads as GoHighLevel Contacts or use GoHighLevel's pipeline/opportunity model for lead-stage tracking.

ZeyOS

Item

maps to

HighLevel

Product

1:1
Fully supported

ZeyOS Items (inventory and product catalog with barcode, model, and custom fields) map to GoHighLevel Products. Stock quantities from ZeyOS's automated inventory system do not migrate because GoHighLevel has no native inventory management. We store the last known stock quantity as a custom Product property and flag the absence of live inventory sync for the customer's admin to address via Zapier or a dedicated inventory integration.

ZeyOS

Project

maps to

HighLevel

Opportunity or Custom Project Object

lossy
Fully supported

ZeyOS Projects with Tasks, subtasks, and time entries require restructuring in GoHighLevel. For service businesses, we map Projects to GoHighLevel Opportunities with a custom Project Name field and Tasks as GoHighLevel Tasks linked to the Contact. For project-management-heavy teams, we pre-create a GoHighLevel Custom Object named 'Project' with lookups to Contact and custom fields for project status, budget, and dates. The customer selects the model during scoping.

ZeyOS

Task

maps to

HighLevel

Task

1:1
Fully supported

ZeyOS Tasks belonging to Projects map to GoHighLevel Tasks with assignee, due date, and status preserved. Parent-Project linkage is maintained by adding the GoHighLevel Opportunity or Custom Project ID as a custom Task field since GoHighLevel Tasks do not have a native Project lookup. ZeyOS custom workflow flags on Tasks migrate as GoHighLevel Tags or custom task properties.

ZeyOS

Ticket

maps to

HighLevel

Opportunity (support pipeline) or Custom Ticket Object

lossy
Fully supported

ZeyOS Tickets (Helpdesk with email integration and subject-line ticket numbering) map to GoHighLevel as either a separate pipeline stage within the Opportunities object or as a GoHighLevel Custom Object named 'Ticket' with Status, Priority, and linked Contact. We recommend the Custom Object approach if the customer needs a separate support queue from their sales pipeline.

ZeyOS

Contract

maps to

HighLevel

Custom Contract Object or Opportunity

1:1
Fully supported

ZeyOS Contracts (subscription or service agreements tied to Accounts) map to a GoHighLevel Custom Object named 'Contract' with Account lookup, start/end dates, and contract value. Contract terms and renewal rules require manual rebuild in GoHighLevel; we deliver the contract metadata and a written recommendation for renewal reminder workflows using GoHighLevel's automation builder.

ZeyOS

User

maps to

HighLevel

User

1:1
Fully supported

ZeyOS Users (team members who own records and create files) map to GoHighLevel Users by email match. We resolve ZeyOS user_id to GoHighLevel User ID for owner assignments on Contacts, Opportunities, and Tasks. Inactive ZeyOS users are flagged for deactivation review in GoHighLevel before migration begins.

ZeyOS

Quote, Order, Delivery, Invoice

maps to

HighLevel

Custom Financial Objects

1:1
Fully supported

ZeyOS's five financial objects (Quotes, Orders, Deliveries, Invoices) form a billing pipeline that GoHighLevel does not natively replicate. We create GoHighLevel Custom Objects for each financial type with line items, totals, dates, and status. Audit-locked ZeyOS invoices are sequenced in strict chronological order before import and flagged if any are out of sequence, because locked records cannot be modified or deleted via the ZeyOS API after booking.

ZeyOS

Activity (calls, emails, meetings, notes)

maps to

HighLevel

Activities via GoHighLevel API

1:1
Fully supported

ZeyOS Activities (engagements linked to Accounts or Contacts) map to GoHighLevel Contacts with timeline entries. Calls migrate as GoHighLevel call log entries; emails as activity notes; meetings as calendar events with the Contact linked. We use GoHighLevel's REST API to insert activities in chronological order to preserve the timeline sequence. Note attachments migrate as GoHighLevel documents linked to the Contact.

ZeyOS

Time Entry

maps to

HighLevel

Custom Time Entry Object or Task

1:1
Fully supported

ZeyOS Time Entries (billable or non-billable hours against Projects, Tasks, or Tickets) map to a GoHighLevel Custom Object named 'TimeEntry' with linked Contact, Project reference, date, hours, and description. If the customer uses GoHighLevel's built-in task tracking, time entries attach as custom fields on the relevant Task.

ZeyOS

Document (files table)

maps to

HighLevel

Document

1:1
Fully supported

ZeyOS files stored in the files table with binary blobs in the binfile column are downloaded individually via the ZeyOS REST API and re-uploaded to GoHighLevel Documents linked to the parent Contact, Opportunity, or Project record. Files exceeding 25MB are flagged for customer review before import because GoHighLevel has documented upload size limits. We validate MIME types and convert non-standard formats as needed.

ZeyOS

Custom Fields (fields table extdata)

maps to

HighLevel

Custom Properties

lossy
Fully supported

ZeyOS custom fields exposed via the fields table and extdata JSON pattern in the REST API are read as field definitions and mapped to GoHighLevel custom properties with equivalent data types. Multi-select, date, number, and text field types map directly; ZeyOS-specific types are inferred from the extdata structure. We create the GoHighLevel custom properties before any data import so that the destination fields exist during record insertion.

Pair-specific challenges

  • Audit-locked ZeyOS invoices require chronological sequencing before import

    ZeyOS marks invoices as immutable once booked — they cannot be edited or deleted via the API after that point. We sequence invoice imports in strict chronological order and flag any out-of-sequence invoices for manual review before import to prevent locked-record conflicts. Customers must confirm their invoice chronology during scoping. If ZeyOS contains invoices with gaps or out-of-order booking dates, those invoices cannot be imported in the correct sequence without violating the ZeyOS immutability constraint, and we raise this as a data quality issue before migration begins.

  • No bulk API in ZeyOS forces iterative record-by-record migration

    ZeyOS exposes only a REST API at cloud.zeyos.com/{INSTANCE}/api/v1/ with no documented bulk import or batch endpoint. We paginate through results and insert records individually into GoHighLevel, which can extend migration timelines for large record sets. We parallelize where the ZeyOS API permits and implement exponential backoff on rate-limit responses. For migrations exceeding 50,000 records, we advise customers of the extended timeline and consider phased migration windows.

  • Unix epoch timestamps must convert to ISO 8601 before GoHighLevel import

    ZeyOS stores creationdate, moddate, and other date columns as int8 Unix timestamps (seconds since 1970-01-01). GoHighLevel's REST API expects ISO 8601 datetime strings. We explicitly convert each epoch value during extraction and validate that the resulting dates fall within GoHighLevel's supported range. Dates predating 1970 or exceeding GoHighLevel's ceiling are flagged for customer review before insertion.

  • Binary file attachments require individual blob download and re-upload

    ZeyOS stores file content in a binfile column accessible via the REST API. We retrieve each binary blob individually and re-upload it to GoHighLevel Documents linked to the parent record. Files with non-standard MIME types, corrupted headers, or sizes exceeding 25MB require additional handling and are flagged for manual review. This process is significantly slower than text-field migration and should be scoped separately during discovery.

  • ZeyOS iXML scripts and ZeyOS workflows do not migrate to GoHighLevel automations

    ZeyOS uses a custom iXML scripting layer for business logic that has no equivalent in GoHighLevel's visual workflow builder. We do not migrate iXML scripts as code. Similarly, ZeyOS internal workflows and automation rules do not map to GoHighLevel's trigger-based automations. We deliver a written inventory of every ZeyOS workflow and iXML script with a description of what it does, so the customer's admin can rebuild the logic in GoHighLevel's automation builder or engage a GoHighLevel partner for the rebuild.

Migration approach

Six steps for a successful ZeyOS to HighLevel data migration

  1. Discovery and ZeyOS API audit

    We audit the source ZeyOS instance via its REST API at cloud.zeyos.com/{INSTANCE}/api/v1/ covering all object types (Accounts, Contacts, Leads, Items, Projects, Tasks, Tickets, Contracts, Documents, Users, Quotes, Orders, Deliveries, Invoices, Time Entries, Activities), custom field definitions from the fields table, file attachment count and total blob size, and the invoice chronology for any audit-locked records. We produce a written scope document with record counts, data quality flags, and a recommendation on whether to use GoHighLevel native objects or custom objects for ZeyOS's ERP-layer records.

  2. GoHighLevel schema design and custom object provisioning

    We design the GoHighLevel destination schema before any data moves. This includes creating custom objects for ZeyOS ERP-layer records (Contracts, Financial objects, Time Entries) that have no native GoHighLevel equivalent, configuring custom properties on Contact to receive ZeyOS extdata fields, designing the project model (Opportunity-based or Custom Project object), and defining the migration-specific tag taxonomy for ZeyOS Leads. Schema is created in GoHighLevel's test environment first for validation.

  3. Financial object chronology validation and invoice sequencing

    We extract the full invoice history from ZeyOS and validate that records are in strict chronological order by booking date. Any invoices with out-of-sequence booking dates are flagged for customer review because they cannot be modified or deleted post-booking in ZeyOS. We provide the customer with a written chronology report and require sign-off before proceeding to invoice import. This step is a prerequisite for the financial object migration phase.

  4. Test migration into GoHighLevel staging environment

    We run a full migration into GoHighLevel's staging or sandbox environment using production-like data volume. The customer reconciles record counts, spot-checks 25-50 records for data accuracy (name spelling, email validity, phone formats, date values, file attachment presence), and reviews the custom object structures. Any mapping corrections happen in this phase. We do not proceed to production migration without written customer sign-off on the test migration results.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Users (validated against GoHighLevel User list), Accounts (with Locations), Contacts (with Company linkage), Leads (with migration tags), Items (as GoHighLevel Products without inventory), Projects (as Opportunities or Custom Projects per the agreed model), Tasks (with parent linkage), Tickets, Contracts, Financial objects (Quotes, Orders, Deliveries, Invoices in chronological sequence), Activities, Time Entries, and Documents (binary blobs). Each phase emits a reconciliation report before the next phase begins.

  6. Cutover, delta sync, and automation inventory delivery

    We freeze ZeyOS writes during cutover, run a final delta migration of any records modified during the migration window, then enable GoHighLevel as the system of record. We deliver a written inventory of every ZeyOS workflow, iXML script, and automation rule with a description of its purpose and recommended GoHighLevel automation equivalent. We support a 72-hour hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild ZeyOS workflows as GoHighLevel automations inside the migration scope; that is a separate engagement.

Platform deep dives

Context on both ends of the pair

ZeyOS logo

ZeyOS

Source

Strengths

  • Unified platform combining CRM, ERP, and Groupware under a single subscription reduces tooling sprawl.
  • Free tier for up to five users enables teams to onboard and evaluate the platform without upfront cost.
  • Open PostgreSQL schema and REST API provide direct database access for migrations and integrations.
  • Audit-proof financial transactions (quotes, orders, invoices) satisfy compliance requirements for locked records.
  • Integrated inventory management with automated stock transactions on every delivery.

Weaknesses

  • Very limited public review presence reduces ability to gauge real-world customer satisfaction and longevity.
  • Smaller market footprint compared to Odoo, NetSuite, or HubSpot raises vendor risk concerns.
  • Custom iXML scripting language creates a learning curve for teams accustomed to standard integration approaches.
  • No documented bulk API means large migrations require iterative record-by-record API calls.
  • Pricing model is primarily per-user, which can become expensive as teams scale beyond 20-30 users.

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 migrations land between three and five weeks for accounts under 10,000 Contacts, 3,000 Projects, and a moderate file attachment library. Migrations with large invoice histories requiring chronology validation, over 500 binary file attachments, or complex project-to-opportunity restructuring move to seven to ten weeks. The ZeyOS REST API's lack of a bulk endpoint is the primary timeline driver; we can only paginate through records iteratively.
