Overview
OnePageCRM and HubSpot take opposite approaches to contact management. OnePageCRM stores contacts with a flat schema of default and custom fields plus a unique Next Action date and text pair. HubSpot models contacts as a properties bag with lifecycle_stage as a unifying contact property. We map OnePageCRM contact_name to HubSpot firstname and lastname, OnePageCRM status labels to HubSpot lifecycle_stage custom properties, and Next Action (text + date) to a custom Next_Action_Text__c and Next_Action_Date__c property pair so your action history survives the migration. Organizations become HubSpot Companies. Deals migrate to HubSpot Deals with OnePageCRM stage names mapped to HubSpot pipeline stage values — each OnePageCRM deal pipeline becomes a HubSpot pipeline. Notes, calls, and meetings become HubSpot engagement notes and tasks. Custom fields migrate as custom HubSpot properties. OnePageCRM Autoflow workflows cannot migrate and must be rebuilt in HubSpot's automation tools — we export your Autoflow definitions as a rebuild reference before the migration runs. We read from OnePageCRM's v3 REST API using paginated endpoints, transform the JSON payloads to HubSpot property format, and load via HubSpot's CRM Objects and Associations bulk API with a 24–48 hour delta-pickup window to capture any records modified during cutover.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a OnePageCRM 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.
OnePageCRM
Contact
HubSpot
Contact
1:1OnePageCRM contacts map to HubSpot contacts. The contact_name field is split into firstname and lastname properties on the HubSpot contact. All standard contact fields (email, phone, jobtitle, address properties) map directly. OnePageCRM's primary organization becomes the HubSpot contact's primary company association via the associations API.
OnePageCRM
Organization
HubSpot
Company
1:1OnePageCRM organizations map to HubSpot companies. Organization name becomes the Company name property. Industry, phone, website, employee count, and annual revenue map to their HubSpot equivalents. Custom organization fields map to custom HubSpot company properties. HubSpot's company record must exist before contact associations are created.
OnePageCRM
Deal
HubSpot
Deal
1:1OnePageCRM deals map to HubSpot deals. Deal name, amount, close date, owner, and contact association carry over. OnePageCRM stage labels map to HubSpot pipeline stage values via a value-mapping table. Multi-contact deals in OnePageCRM map to one primary contact on the HubSpot deal plus additional contacts via Deal Contact Roles.
OnePageCRM
Pipeline
HubSpot
Pipeline
1:1Each OnePageCRM deal pipeline becomes a HubSpot pipeline. OnePageCRM does not enforce a 1:N pipeline-per-deal model the same way HubSpot does, so all deals from one OnePageCRM pipeline are assigned to the corresponding HubSpot pipeline. Multi-pipeline accounts require separate HubSpot pipeline setup before migration.
OnePageCRM
Contact Status
HubSpot
lifecycle_stage (custom property)
1:1OnePageCRM status labels (Prospect, Contacted, Qualified, Unqualified, Won, Lost) map to HubSpot lifecycle_stage values. If your OnePageCRM uses custom status labels, each label maps value-by-value to a custom picklist property on HubSpot contacts. HubSpot's built-in lifecycle_stage options can be used if the labels align, otherwise a custom property is created.
OnePageCRM
Next Action (text + date)
HubSpot
Next_Action_Text__c + Next_Action_Date__c (custom properties)
1:1OnePageCRM's Next Action is a first-class contact concept with both text and a due date. HubSpot has no native Next Action field. We create two custom contact properties (Next_Action_Text__c and Next_Action_Date__c) and migrate each contact's Next Action. The original Next Action timestamp is preserved in the date property. This is the most identity-specific migration item in this pair.
OnePageCRM
Custom Field (Contact)
HubSpot
Contact (custom property)
1:1OnePageCRM custom fields on contacts migrate to HubSpot custom contact properties. The property type is inferred from OnePageCRM's field type (text, number, date, picklist). HubSpot requires custom properties to be created in the portal before migration — we deliver a property creation checklist alongside the migration plan.
OnePageCRM
Note
HubSpot
Note (engagement)
1:1OnePageCRM notes attached to contacts map to HubSpot engagement notes on the contact timeline. The note body becomes the HubSpot note body. Note create date and owner are preserved as engagement metadata. Notes on deals migrate to HubSpot deal notes.
OnePageCRM
Call / Meeting
HubSpot
Task / Event (engagement)
1:1OnePageCRM logged calls map to HubSpot engagement tasks with Type='Call'. Meetings map to HubSpot events with subject, start/end times, and owner preserved. The OnePageCRM call outcome (Connected, No Answer, Left Voicemail) migrates as a custom engagement property for reporting continuity.
OnePageCRM
Tag
HubSpot
HubSpot list or custom multi-select property
1:1OnePageCRM tags on contacts migrate to HubSpot contact properties. We map tags to a custom multi-select property (Contact_Tags__c) to preserve all tags on each contact record. If tag-based segmentation is critical, we also create static HubSpot lists matching each tag for use in workflows and campaigns.
OnePageCRM
Autoflow Workflow
HubSpot
HubSpot Workflow
1:1OnePageCRM Autoflow workflows (saved action sequences, email sequence triggers, and automation rules) have no migration path to HubSpot. We export your Autoflow definitions as a structured reference document — action triggers, sequence steps, and conditions — for your HubSpot admin to rebuild using HubSpot's workflow builder.
OnePageCRM
Email (conversations)
HubSpot
HubSpot Conversations (rebuild required)
1:1OnePageCRM email threads stored within the CRM cannot be exported via CSV or API. We preserve the contact's email address and association but cannot migrate the conversation history. Teams using OnePageCRM's shared inbox should plan to rebuild conversation context in HubSpot's Conversations inbox tool post-migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
OnePageCRM gotchas
Email bodies and attachments are not exported from OnePageCRM
Duplicate detection fires after import, not during
API rate limit of 5 req/s constrains bulk extraction
Custom Fields must be pre-created before import
Merge Import updates existing contacts rather than creating new ones
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Audit OnePageCRM data volume and schema
FlitStack runs a read-only API audit against your OnePageCRM account to count contacts, organizations, deals, custom field definitions, and pipeline configurations. We compare the record count against the 9,999-row CSV export cap to determine if batched extraction is required. We also capture your status label definitions, pipeline names, stage labels, and any custom field types before building the mapping plan.
Create HubSpot custom properties and pipelines
Before data loads, we deliver a HubSpot setup checklist: create the custom contact properties for Next Action text and date, lifecycle stage (or custom picklist for non-standard status labels), contact tags, and any custom deal and company properties identified during the audit. We also map each OnePageCRM pipeline to a HubSpot pipeline and configure stage names and probabilities to match your OnePageCRM stage labels. This checklist can be completed by your HubSpot admin or by FlitStack on your behalf.
Extract from OnePageCRM and transform data
We pull data from OnePageCRM's v3 REST API using paginated endpoints, handling the platform's rate limit of 5 requests per second average (10 per second burst). Data is extracted in JSON, transformed to HubSpot property format (splitting contact_name into firstname/lastname, mapping status labels to lifecycle_stage values, converting Next Action to custom properties), and validated against the mapping plan. Email attachments and conversation threads are flagged as unrecoverable — we document their absence in the audit report.
Run a sample migration with field-level diff
A representative slice of records (typically 100–500 per object type) migrates to HubSpot first. We generate a field-level diff report showing every source field, its mapped HubSpot property, the value on the source record, and the value inserted in HubSpot. You review the diff to confirm status-label mapping, Next Action preservation, owner resolution, and pipeline mapping before the full migration commits. Autoflow workflow export is delivered at this stage as a reference document for your HubSpot admin.
Execute full migration with delta-pickup and audit log
The full migration loads all validated records into HubSpot via the CRM Objects bulk API. During the cutover window your team continues working in OnePageCRM — scoped read access means no disruption to daily use. A delta-pickup window (24–48 hours) captures any records created or modified in OnePageCRM after the bulk run. Every operation is logged to an audit trail. One-click rollback reverts all migrated records if reconciliation reveals unexpected data issues. Once verified, your team goes live on HubSpot and OnePageCRM is decommissioned.
