Overview
Grow CRM and HubSpot take fundamentally different approaches to data organization. Grow CRM uses a multi-module structure — clients, leads, opportunities, tasks, invoices, payments, estimates, help desk tickets, and a client-facing portal — all managed through a self-hosted PHP application with per-field custom field support. HubSpot consolidates this into a flat contact model with lifecycle_stage as the primary state property, deal pipelines with stage-level probability, companies, and a tickets object for support. The migration challenge is two-fold: Grow CRM's modular structure (invoices, payments, estimates) has no native HubSpot equivalent and must be stored as custom properties or custom objects, and Grow CRM's lead/opportunity split must be resolved into HubSpot's contact lifecycle model where a single contact record carries all stage history. We extract Grow CRM data via its export API, normalize field names to HubSpot's snake_case property naming convention, map custom field types to HubSpot's equivalent types (text, number, date, dropdown, multi-select), and load via HubSpot's Contacts API or bulk CSV import. Relationships between clients and companies are preserved as HubSpot company associations. The delta-pickup window (24–48 hours) captures any records modified during the cutover so the final HubSpot state matches Grow CRM's last-write-wins at go-live. Automations, workflows, and invoice templates do not migrate — we document Grow CRM's workflow logic for your team to rebuild natively in HubSpot.

Object mapping
Each row shows how a Grow CRM object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Grow CRM
Client
HubSpot
Contact
1:1Grow CRM clients map to HubSpot contacts. The contact's primary company is linked via HubSpot's company association. All standard client fields (name, email, phone, address) map to HubSpot's equivalent contact properties. Custom fields on the client record become HubSpot custom contact properties.
Grow CRM
Lead
HubSpot
Contact (lifecycle stage routing)
1:manyGrow CRM leads that are open and not yet converted to clients map to HubSpot contacts with a lifecycle stage value of 'lead'. If the lead has been contacted, the HubSpot lifecycle stage routes to 'lead' or 'mql' based on Grow CRM's lead status field. Converted leads that match existing clients merge into the existing HubSpot contact record.
Grow CRM
Company
HubSpot
Company
1:1Grow CRM companies map 1:1 to HubSpot companies. Company name, domain/website, industry, employee count, and annual revenue map to HubSpot's equivalent company properties. Parent-child company hierarchies in Grow CRM are preserved using HubSpot's parent company field, maintaining organizational structure across the migration.
Grow CRM
Opportunity
HubSpot
Deal
1:1Grow CRM opportunities map to HubSpot deals. The opportunity amount maps to deal amount, and the assigned user maps to the HubSpot deal owner. Grow CRM opportunity status (open/won/lost) maps to HubSpot deal pipeline stages — open maps to the first active stage, won/lost map to the terminal stages.
Grow CRM
Pipeline / Status
HubSpot
Deal Pipeline + Stage
1:1Grow CRM's opportunity status field (open/won/lost) becomes a HubSpot deal pipeline. If Grow CRM uses multiple custom status values, we create a HubSpot pipeline with stages named to match the source values. Stage probability is applied per HubSpot's pipeline configuration or set to a default 50% for mid-funnel stages.
Grow CRM
Task
HubSpot
Task
1:1Grow CRM tasks map to HubSpot tasks. Task subject, description, due date, priority, and assignee are mapped to HubSpot's equivalent task properties. The original create date is preserved as a custom datetime field since HubSpot's CreatedDate reflects migration time. Completed status maps to HubSpot task completion.
Grow CRM
Invoice
HubSpot
Custom Object: Invoice
1:1Grow CRM invoices have no native HubSpot equivalent. We create a custom HubSpot object (available on Professional and Enterprise plans) called 'Invoice' with properties for invoice number, amount, status, client link, issue date, and due date. Line items are stored as a JSON property or as a notes attachment since HubSpot custom objects do not support native sub-rows.
Grow CRM
Payment
HubSpot
Custom Object: Payment
1:1Grow CRM payment records migrate to a HubSpot custom object called 'Payment'. Each payment links to the related Invoice custom object and the Contact. Properties include payment amount, date, method (Stripe/PayPal), and status. Payment method values require value mapping since Grow CRM stores them differently than HubSpot accepts.
Grow CRM
Estimate
HubSpot
Custom Object: Estimate
1:1Grow CRM estimates migrate as a HubSpot custom object. Properties include estimate number, total amount, status (draft/sent/accepted/rejected), related contact, and line items stored as a text property. Accepted estimates that convert to invoices are flagged with a status property and cross-linked to the Invoice custom object.
Grow CRM
Help Desk Ticket
HubSpot
Ticket
1:1Grow CRM help desk tickets map to HubSpot tickets. Ticket subject, description, status (new/open/resolved/closed), priority, and assignee map to HubSpot's ticket properties. Grow CRM's client-facing portal ticket thread becomes HubSpot ticket conversations. Original ticket create date is preserved as a custom datetime property.
Grow CRM
Knowledgebase Article
HubSpot
HubSpot Knowledge Base
1:1Grow CRM knowledgebase articles have no HubSpot equivalent at the CRM object level. Articles are exported as a structured JSON dataset and HTML content package. Your team can import these into HubSpot's Knowledge Base manually or via HubSpot's CMS import tools. The content and structure are preserved but migration requires a separate manual step.
Grow CRM
Proposal
HubSpot
Custom Object: Proposal
1:1Grow CRM proposals migrate as a HubSpot custom object with properties for proposal title, content (stored as a long-text or notes attachment), status, related contact, and proposal value. Attachments are re-uploaded to HubSpot file storage and linked via URL property. Proposal workflow status is preserved as a pick-list property.
Grow CRM
User / Team Member
HubSpot
HubSpot User
1:1Grow CRM user accounts (sales reps, admins) are matched to HubSpot users by email address. Active users are invited to HubSpot before migration. Unmatched users are flagged — their records are assigned to a fallback HubSpot owner (typically the admin) and the original user ID is preserved in a custom field for post-migration reconciliation.
Grow CRM
Client Portal / Project
HubSpot
Custom Object: Project (or Deal with custom properties)
1:1Grow CRM's client dashboard and project tracking have no direct HubSpot equivalent. Projects migrate as a HubSpot custom object with properties for project name, client link, status, start date, and end date. Tasks within a project link to the project record via a lookup property. The client-facing portal view must be rebuilt in HubSpot's portal product or via a CMS-based solution.
Grow CRM
Attachment / File
HubSpot
HubSpot File
1:1Grow CRM file attachments (on clients, leads, opportunities, tasks) are downloaded and re-uploaded to HubSpot's file storage. Files are linked to the destination record via HubSpot's file association model. File size limits apply — HubSpot's default is 10MB for individual files via the UI, higher via API.

Migration approach
Audit Grow CRM data structure and export via API
We connect to Grow CRM's export API and pull a complete inventory of all modules: clients, leads, opportunities, tasks, invoices, payments, estimates, help desk tickets, knowledgebase, and custom fields. We document every field's data type, pick-list values, and relationship links. This inventory becomes the source-of-truth for the field mapping spreadsheet and surfaces any modules (knowledgebase, client portal) that require post-migration manual work rather than automated import.
Create HubSpot schema: pipelines, custom objects, and properties
Before data moves, we set up HubSpot's destination schema: deal pipelines with named stages and probability per stage, custom objects for Invoice, Payment, and Estimate (requires Professional+), ticket pipeline, and all custom contact/company properties from Grow CRM. We match Grow CRM pick-list values to HubSpot pick-list values and create any HubSpot pick-list values that don't yet exist. This step runs in parallel with the source audit so both sides are ready simultaneously.
Resolve owners and users by email match
Grow CRM user accounts are matched to HubSpot user accounts by email address. Active Grow CRM users are pre-invited to HubSpot before migration so their user records exist to receive record assignments. Any Grow CRM user without a HubSpot counterpart is flagged — their records are assigned to a fallback HubSpot owner and the original user ID is preserved in a source_system_id__c property for post-migration reconciliation. This ensures zero records land in HubSpot without an owner.
Run a sample migration with field-level diff
A representative slice — typically 200–500 records spanning clients, leads, opportunities, tasks, invoices, and tickets — migrates first. We generate a field-level diff between the Grow CRM source record and the HubSpot destination record, verifying that field names, values, and types match correctly. Custom object records are spot-checked for property completeness. This pass identifies any field mapping corrections before the full migration commits. Any pick-list value mismatches are corrected in the mapping table before proceeding.
Execute full migration with delta-pickup window
The full Grow CRM dataset loads into HubSpot: companies first, then contacts (clients and leads), then deals, tasks, tickets, and custom objects. All relationships are resolved (contact-company links, deal-contact associations, ticket-contact links). A delta-pickup window (24–48 hours after initial load) captures any Grow CRM records created or modified during the cutover window. The audit log records every operation. If reconciliation finds discrepancies, one-click rollback reverts the HubSpot state to pre-migration. Client portal content, knowledgebase articles, and workflow definitions are delivered as structured exports for your team to rebuild in HubSpot.
