OnePageCRM to HubSpot
Action-focused CRM for small sales teams, built around contacts, companies, deals and next actions.
OnePageCRM data can move into HubSpot, landing mainly in Sales Hub. 2 of 7 mapped objects move directly (Contacts and Deals); 4 items need manual work and 2 do not move. Plan roughly 1-2 weeks for a small move and 6-12 weeks for a large one.

No price list: cost follows volume, custom objects and how much logic must be rebuilt. Answer four quick questions for a planning range.
The three scenarios
Small migration
<5k contacts, <1k deals
CSV-based move.
Mid migration
5k-50k contacts, 1k-10k deals
API extraction for activities.
Large migration
>50k contacts, >10k deals
Custom scripts, multiple pipelines and automation rebuild.
What moves the number
Timeline ranges are planning estimates, not a quote. A partner confirms scope after discovery.
Access, mapping and limits
Start with how data leaves OnePageCRM: what you need to get in, what lands in HubSpot, and what will not.
REST API v3 (JSON), with webhooks, OQL and an MCP server
The user_id and API key from the Apps > API page, or an approved OAuth 2.1 app.
Not confirmed in sources. An admin-level user is assumed to be needed for a full-account export.
Choose your route
How will you move the data?
No native connector was found.
- You need: The user_id and API key from the Apps > API page, or an approved OAuth 2.1 app.
- Permission: Not confirmed in sources. An admin-level user is assumed to be needed for a full-account export.
Native imports often bring over only some data, so check coverage per object in the mapping below.
Export each object, clean it, then import it into HubSpot.
- Contacts CSV/Excel export, with an option to include notes and calls
- Deals CSV/Excel export (pending or closed)
- Deal List export from the Pipeline
- REST API read of contacts, companies, deals, actions, notes, calls and meetings
Limits: To confirm
Migration and sync tools can move more than a plain import. Confirm which objects each one supports before you choose.
Best when volume is high, custom objects are many or automation is heavy. That is the Large scenario: 6-12 weeks, usually phased.

Hover or tap anything on the left to see where it lands.
| Source object | In HubSpot | Moves | Notes |
|---|---|---|---|
| Contacts | Contacts | yes | CSV export can be filtered by tag, status, owner and so on. Custom fields export as columns. |
| Companies (organizations) | Companies | partial | The company name is a contact field in the CSV. The API exposes companies, so the dedupe and association logic needs building. |
| Deals | Deals | yes | The export includes Deal ID, contact, owner, amount, stage, pipeline name, close date, lost reason and custom fields. |
| Actions (next actions) | Tasks | partial | Actions are available via the API. Whether the CSV exports them is unconfirmed. |
| Notes, calls and meetings | Notes | partial | The contacts export has a dataset that includes notes and calls. Calls map to Calls and meetings to Meetings. The API is the more complete route. |
| Users (owners) | Contacts | manual | Owner appears as a name column in the exports. You must create or match HubSpot users and map owners yourself. |
| Pipelines and stages | Deals | manual | Sales and Delivery pipelines exist. Rebuild them in HubSpot from the stage names in the export. |
What to expect
No export of automation configuration was found, so they must be rebuilt in HubSpot.
Only record-level exports were found. Reports are rebuilt in HubSpot.
OnePageCRM's action-stream model and status labels have no direct HubSpot equivalent.
No permission export was found.
The contacts and deals exports are separate files that don't share fields.
The CSV may not carry every activity or contact-to-deal link.
Choose the dataset that includes notes and calls, or extract via the API.
Use the API to pull IDs and associations, and dedupe before import.
Activate all custom fields before exporting.
Throttle requests and follow the vendor's rate-limit page.
Data governance and compliance
Decide what is allowed to move before anything is exported. Tick each gate once it is agreed.
How we researched this page
How much to trust each section, and where it comes from.
Vendor API docs and export help pages support access and the main objects. HubSpot-side import mapping, a native connector, rate-limit figures, residency and certifications were not verified, so those rest on category-level knowledge.
