Overview
Bigin by Zoho CRM and HubSpot take fundamentally different approaches to the same sales data. Bigin organizes everything around Team Pipelines and sub-pipelines, storing contacts, companies, and deals in a flat relationship model where associations are implicit. HubSpot splits Contacts and Companies into separate objects, uses lifecycle stages as a contact-state property, and models deal progress through named pipelines with configurable stages. The migration must therefore translate Bigin's pipeline-stage structure into HubSpot's deal pipeline model, re-establish contact-company associations using HubSpot's association API (which caps at two simultaneous association files during import), and handle the fact that Bigin has no native lifecycle stage equivalent that maps directly to HubSpot's contact lifecycle property. FlitStack AI sequences the migration so parent company records migrate before contacts (foreign-key resolution), resolves owners by email match against HubSpot users, and preserves original create/update timestamps as custom fields since HubSpot overwrites Createdate at import time. Tags migrate as HubSpot properties; workflow rules and automation logic do not transfer and must be rebuilt in HubSpot's automation tools. All standard objects — Contacts, Companies, Deals, Tasks, Events, Notes, and Products — transfer with their field-level data intact.
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 Bigin by Zoho 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.
Bigin by Zoho CRM
Contact
HubSpot
Contact
1:1Bigin contacts map directly to HubSpot contacts. The primary company association (stored as Account_Name in Bigin) translates to a Company association in HubSpot via the association API. Multi-company contacts require a primary selection rule — by default the most recently modified company is assigned as the primary, with secondary companies surfaced as additional company associations.
Bigin by Zoho CRM
Company
HubSpot
Company
1:1Bigin companies map to HubSpot companies. Parent-child company hierarchies in Bigin (represented via a Parent Company field) translate to HubSpot's subsidiary association model, preserving the corporate structure. All standard company fields including phone, website, industry, employee count, and address components map directly to their HubSpot counterparts. Bigin's industry pick-list values undergo value mapping to align with HubSpot's industry taxonomy before import.
Bigin by Zoho CRM
Deal
HubSpot
Deal (Opportunity)
1:1Bigin deals map to HubSpot deals (internally called Opportunities). Each Bigin Team Pipeline translates to a named HubSpot pipeline. The deal name, amount, expected close date, owner, and description fields carry over directly. Stage mapping is value-by-value per pipeline, handled in the Pipeline Stage value mapping row.
Bigin by Zoho CRM
Pipeline Stage
HubSpot
Deal Stage (per Pipeline)
1:1Bigin stage names (e.g., 'Qualification', 'Proposal Sent', 'Closed Won', 'Closed Lost') map to HubSpot deal stage names. HubSpot allows different stage sets per pipeline, so if Bigin has multiple pipelines, each pipeline's stage set is created as a separate HubSpot pipeline with its own stage sequence. Stage probabilities are applied per HubSpot's pipeline configuration.
Bigin by Zoho CRM
Tag
HubSpot
Contact / Company / Deal Property
1:1Bigin tags are module-level labels (a contact can have different tags than a deal). HubSpot has no native tag object for CRM records, but tags translate to a multi-value custom property called Tags__c on each object. Up to 20 tags per module migrate from Bigin; if a record has more than 20, the first 20 by modification date are retained per Bigin's import limit.
Bigin by Zoho CRM
Task
HubSpot
Task
1:1Bigin tasks map to HubSpot tasks with subject, due date, status, priority, and owner preserved. Task status values (Not Started, In Progress, Completed, Deferred) map to HubSpot task status equivalents. HubSpot tasks do not have a native priority field — priority is stored as a custom pick-list property if needed.
Bigin by Zoho CRM
Event
HubSpot
Meeting (Engagement)
1:1Bigin events (meetings, calls) map to HubSpot engagements of type MEETING or CALL. Original start time, end time, and location fields are preserved. HubSpot stores these as engagements on the associated contact or company record. Recurring events in Bigin are 'squashed' into a single event entry per Bigin's export limitation.
Bigin by Zoho CRM
Note
HubSpot
Note
1:1Bigin notes map to HubSpot notes attached to the parent record (Contact, Company, or Deal). Note body text and the associated record link are preserved. Bigin notes that contain attachments re-upload those files as HubSpot file attachments; inline images in rich-text notes are extracted and re-hosted.
Bigin by Zoho CRM
Product
HubSpot
Product
1:1Bigin products map to HubSpot products with name, unit price, and description preserved. Bigin's product-to-deal line item relationship translates to HubSpot's deal-to-product association via line items. Products that exist only as deal-level descriptions (without a formal product record) are created as HubSpot products before the deal migration runs.
Bigin by Zoho CRM
User (Owner)
HubSpot
User (Owner)
1:1Bigin user records are resolved by email address against HubSpot portal users. If a Bigin owner email matches a HubSpot user email, the record is assigned to that HubSpot user. If no match is found, records are flagged before migration and assigned to a designated fallback HubSpot user of your choice. We do not create HubSpot users — that requires an admin action in the destination portal.
Bigin by Zoho CRM
Custom Field (per module)
HubSpot
Custom Property
1:1Bigin custom fields (up to 25 per module on Premier) map to HubSpot custom properties. For each custom field we inspect the field type (text, pick-list, date, number, checkbox) and create a matching HubSpot property of the same type. Bigin's custom field API naming convention (<namespace>__<field_label>) is preserved as the HubSpot property internal name for traceability.
Bigin by Zoho CRM
Attachment (record-level)
HubSpot
File (attached to record)
1:1Bigin file attachments on Contacts, Companies, and Deals are downloaded and re-uploaded to HubSpot Files, then attached to the corresponding record. Bigin's 10 export limit per module and per-file size limits are respected during extraction. HubSpot's file size limit is 25MB per file.

Migration approach
Inventory Bigin's schema and data volume
We connect to Bigin's v2 API using OAuth credentials and pull a full schema inventory: module list, field metadata per module, and record counts for Contacts, Companies, Deals, Tasks, Events, Notes, and Products. This inventory identifies every Bigin custom field (by API name and type), every pipeline and stage, and every tag in use. We also extract the user list to build the owner resolution map. No data leaves Bigin during this step — we only read schema metadata and volume statistics. The output is a migration plan document that lists every object, field, and association we will translate.
Pre-create HubSpot custom properties and pipelines
Before any data is written to HubSpot, we create all custom properties that do not have a built-in HubSpot equivalent. This includes Tags__c (multi-value text), source_system_id__c (single-line text), original_create_date__c (date), original_last_modified_date__c (date), and any Bigin custom fields that lack a direct HubSpot match. We also create HubSpot pipelines and stages by reading Bigin's pipeline names and stage names. This step requires a HubSpot admin token with permission to create properties and pipelines. We provide a setup checklist so your HubSpot admin can pre-create these if preferred.
Run sample migration with field-level diff
A representative slice of records — typically 100–500 across Contacts, Companies, Deals, and a sample of Notes and Tasks — is migrated first. We generate a field-level diff comparing each source field value against the corresponding HubSpot field value. The diff report is shared with you before the full run commits. This is the moment to verify lifecycle stage assignment rules, pipeline-to-stage mapping, tag preservation, and owner resolution. Any mapping adjustments are made before the full migration begins. FlitStack AI does not proceed to full migration until you sign off on the diff.
Execute full migration with delta-pickup window
The full migration runs against HubSpot's API. All standard objects are written in the correct dependency order: Companies first (HubSpot requires AccountId before Contact associations), then Contacts with company links, then Deals with contact associations. Owner resolution by email match is applied throughout. A delta-pickup window of 24–48 hours opens at migration completion — during this window, any records modified in Bigin after the initial extraction are re-read and updated in HubSpot. This ensures the final state reflects all changes made during the cutover period. An audit log records every write operation; one-click rollback is available if reconciliation identifies unexpected discrepancies.
