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
<10k contacts
CSV import is enough.
Mid migration
10k-100k records
API or report-based extraction plus workflow rebuild.
Large migration
>100k records with heavy activity
Custom API scripts, plus audit of associations and files.
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 BigContacts: what you need to get in, what lands in HubSpot, and what will not.
REST-style API (vendor announces an API; protocol details unverified)
Choose your route
How will you move the data?
No native connector was found.
- You need: To confirm
- Permission: To confirm
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.
- Report export (reports can be exported in one click)
- Data export for reporting or backup (format not documented in sources)
- Vendor API for custom extraction
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: 8-16 weeks, usually phased.

What to expect
Rules are not portable and must be rebuilt as HubSpot workflows or sequences.
No export path is documented. Rebuild as HubSpot teams and permission sets.
Report definitions don't transfer. Only report output can be exported.
The BigContacts workflow logic is not exportable.
Report builder definitions stay in BigContacts.
Reviewers say export is hard, and it is unclear whether history and associations are included.
Reviewers report limited duplicate detection and merging.
Run a sample export and API pull, then reconcile counts before committing.
Ask vendor support for API docs and a full-data export.
Clean and merge in the source or in staging before import.
Download files separately and re-attach them in HubSpot via Files.
Data governance and compliance
Decide what is allowed to move before anything is exported. Tick each gate once it is agreed.

How much to trust each section, and where it comes from.
Product, API existence, CSV import and report export are supported only by vendor marketing and review sites. No vendor API docs or export help pages were found. Object mapping, rate limits and auth details rest on category-level knowledge.
