Overview
Kartra and HubSpot CRM take fundamentally different approaches to contact data architecture. Kartra stores everything on a single Lead object with tags, lists, and custom fields as properties — it does not have a separate Company object by default, and deals are handled through Kartra's product and transaction engine. HubSpot separates Contacts, Companies, and Deals into distinct objects with a lifecycle_stage property that drives reporting, automation, and marketing-contact billing. The migration must therefore restructure Kartra's flat lead model into HubSpot's relational graph, splitting address data into HubSpot's structured address fields, extracting company names into a Companies object, and mapping Kartra deal/product data into HubSpot Deals with pipeline and stage mapping. Tags and lists require resolution: HubSpot Lists are used for segmentation but do not carry the same automation-trigger semantics as Kartra's lists. Custom fields translate by type — Kartra radio buttons and drop-downs become HubSpot picklists, text areas become long-text fields, and checkboxes map to multi-checkbox or boolean properties. We use Kartra's export CSV as the primary data source (not their API, due to documented rate limits), enrich it with custom field definitions, and load through HubSpot's native import API with field-level validation before committing to the full migration.

Object mapping
Each row shows how a Kartra 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.
Kartra
Lead (Contact)
HubSpot
Contact
1:1Kartra's Lead object maps directly to HubSpot Contact. All standard fields (firstname, lastname, email, phone, address components) map to HubSpot's corresponding contact properties. The Kartra Lead ID is preserved as a custom Source_System_ID__c field on each HubSpot contact for traceability and delta-run deduplication.
Kartra
Lead.company (property)
HubSpot
Company
1:1Kartra stores company name as a property on the Lead. We extract unique company names from all Kartra leads, create a corresponding HubSpot Company record for each unique name, and link the Contact to that Company via HubSpot's 'Associated Company' property. This restructures Kartra's flat model into HubSpot's relational Contact-Company graph.
Kartra
Lead (contact with product purchase history)
HubSpot
Contact + Deal
many:1If a Kartra Lead has associated product purchases or subscriptions, we create a HubSpot Deal linked to the Contact. The Kartra product name becomes the Deal name, purchase amount maps to Deal amount, and subscription start dates map to the Deal's close date. Each product purchase can generate one Deal, preserving the transactional context in HubSpot's pipeline model.
Kartra
Kartra List membership
HubSpot
HubSpot List
1:1Kartra Lists are automation-triggered segments that define who receives sequences and broadcasts. We create a corresponding HubSpot List for each Kartra list and add all Kartra contacts that were members of that list. Note that HubSpot Lists are static by default when populated via import — dynamic list behavior requires HubSpot list-filter setup post-migration.
Kartra
Kartra Tag
HubSpot
HubSpot Contact property (tags)
1:1Kartra's tag field contains comma-separated tags per lead. We map these to HubSpot's native 'tags' property on the Contact, preserving the full tag vocabulary. Tags serve as flat labels in both platforms, though HubSpot's tag automation triggers require post-migration configuration in HubSpot workflows.
Kartra
Kartra Custom Fields (drop_down, radio_button)
HubSpot
HubSpot Contact custom properties (picklist)
1:1Kartra drop-down and radio-button custom fields map to HubSpot single-select picklist properties. Each Kartra pick-list value requires explicit mapping to the corresponding HubSpot pick-list option. We preserve the original Kartra option labels and flag any unmapped values for your team to resolve before migration commits.
Kartra
Kartra Custom Fields (checkbox)
HubSpot
HubSpot Contact custom properties (single-checkbox or multi-checkbox)
1:1Kartra checkbox fields (boolean) map to HubSpot single-checkbox (boolean) properties. For Kartra multi-checkbox fields, we create HubSpot multi-checkbox properties with options matching each Kartra option. We validate the data type mapping during the sample migration phase before committing to the full run, ensuring all boolean values translate correctly.
Kartra
Kartra Custom Fields (text_area, input_field)
HubSpot
HubSpot Contact custom properties (text or long-text)
1:1Kartra text-area and input-field custom fields map to HubSpot text (short) or long-text (textarea) properties based on content length analysis. HubSpot's 512-character limit for short text fields is respected; longer content lands in HubSpot's long-text property type. The content length threshold is applied automatically during the mapping phase.
Kartra
Kartra GDPR Status / GDPR Status Date
HubSpot
HubSpot Contact GDPR consent properties
1:1Kartra exports GDPR status and the date the status was set as separate properties on each lead. We map these to HubSpot's GDPR consent properties — GDPR_consent_to_communicate__c (boolean) and GDPR_date__c (date) — preserving the consent record and original consent timestamp for compliance continuity.
Kartra
Kartra Address fields (Street, City, Zip, Country, State)
HubSpot
HubSpot Contact address property (structured)
1:1Kartra exports address as separate fields: address, city, zip, country, state. HubSpot stores address as a structured address property with sub-fields. We parse Kartra's combined address field into HubSpot's address1, city, zip, country, and state sub-fields. If Kartra's address field contains multi-line content, the first line lands in address1 and additional lines are preserved in a custom notes field.
Kartra
Kartra IP, IP Country, Website
HubSpot
HubSpot Contact custom properties
1:1HubSpot does not have native fields for IP address or IP country. We create custom properties Kartra_IP_Address__c and Kartra_IP_Country__c to preserve this data for geo-targeting and compliance analysis. The Kartra website property maps directly to HubSpot's website property on the associated Company.
Kartra
Kartra social profiles (Facebook, Twitter, LinkedIn, Instagram)
HubSpot
HubSpot Contact social media properties
1:1Kartra stores individual social profile URLs per lead. HubSpot has native social media link properties for LinkedIn, Twitter, Facebook, and Instagram on the Contact record. We map each platform field-by-field to its HubSpot equivalent, preserving the original profile URL for each network.
Kartra
Kartra product/membership access
HubSpot
HubSpot custom object or Deal
1:1Kartra's membership and product access data — which courses or products a lead has purchased access to — has no direct HubSpot CRM equivalent. We preserve this data as custom text fields listing the product/membership names and access dates. For businesses that need active access management, this requires a separate membership management tool or HubSpot's custom objects feature post-migration.
Kartra
Kartra Sequence enrollment status
HubSpot
HubSpot workflow enrollment state
1:1Kartra Sequences are email automation programs with enrollment tracking. HubSpot workflows serve a similar purpose but operate on different trigger semantics. We cannot migrate sequence enrollment state directly — contacts' current sequence positions do not translate to HubSpot workflow enrollment. We preserve sequence names as a custom property (Sequences_Enrolled__c) listing past and current enrollments for reference, and sequence logic must be rebuilt in HubSpot workflows.

Pair-specific challenges
Migration approach
Export Kartra data and build the field mapping plan
We extract your Kartra data using Kartra's native CSV export for Leads, capturing all standard fields, custom fields, tags, list memberships, GDPR properties, and social profile URLs. We retrieve Kartra's custom field definitions via Kartra's API (type, label, options) to build a type-aware mapping table. We then analyze the extracted data for duplicates, missing required fields, and data quality issues — identifying records that will need a default company association in HubSpot and contacts with unmapped tag values. The field mapping plan documents every Kartra field's destination in HubSpot, including custom field creation requirements and value-mapping for pick-list fields.
Create HubSpot Companies from Kartra company-name data
Before loading any Contacts, we extract unique company names from all Kartra leads and create the corresponding HubSpot Company records. This step establishes the Company object so that HubSpot's foreign-key constraints are satisfied when we link Contacts to their primary company. We also populate each Company's website, industry (if inferable from domain), and country fields during this step. Companies are created in HubSpot via the native API with batch processing for efficiency. Any Kartra leads without a company name are flagged — your team decides whether to create a default 'No Company' placeholder Company or leave those contacts unassociated.
Create custom properties in HubSpot and run the sample migration
We create all required HubSpot custom contact properties — for IP address, IP country, GDPR consent fields, original create date, source system ID, and all Kartra custom field translations (picklists, checkboxes, text fields). We then run a sample migration using 100–300 representative Kartra records spanning different tag combinations, list memberships, and custom field values. The sample migration generates a field-level diff report showing every mapped value in Kartra alongside its HubSpot destination. Your team reviews the diff to verify custom field type mapping, pick-list value mapping, and company association accuracy before we commit to the full migration.
Load all Contacts with full field mapping and list enrollments
With the mapping plan approved from the sample, we load all Contacts into HubSpot using HubSpot's native import API with field-level validation. Each Contact receives its mapped standard properties, custom properties, tag assignments, and company association. List memberships are processed by creating a HubSpot List per Kartra list and enrolling the matching contacts. We preserve the original Kartra create date in a custom field since HubSpot's CreatedDate is set at import time. All Kartra lead IDs are stored in the source_system_id__c property for traceability and to support delta-run deduplication.
Capture delta records and validate the full migration
After the initial full migration load, we open a delta-pickup window (typically 24–48 hours) during which any new Kartra records or modified Kartra records are captured and migrated to HubSpot. This ensures that contacts added or updated in Kartra during the cutover window are reflected in HubSpot at go-live. We run a post-migration validation comparing record counts by object, checking for duplicate contacts (matched by email address), verifying custom property completeness, and spot-checking tag and list enrollment accuracy. The audit log captures every operation for reconciliation. One-click rollback is available if validation reveals critical data issues before you confirm acceptance.
