Custom engineered CRM & Customer Success integration

HubSpot to HubSpot integration

Custom engineered for your business by SpotDev's accredited developers

Connect two HubSpot portals so contacts, companies, deals and tickets are shared between them on rules you set: which portal owns each property, which records qualify to cross and how associations are kept, for groups, subsidiaries and regional teams running separate HubSpot accounts.

  • 3–5 weeks typical turnaround
  • £5k-£15k typical investment
  • Private token

Why connect HubSpot to HubSpot

Groups end up with several HubSpot portals through acquisition, regional autonomy or brand separation. Each works on its own, but the moment a customer of one brand talks to another, or head office wants a group view, the portals need to exchange records, and HubSpot's built-in options only go so far.

  • HubSpot's data mirroring shows contact and company data from another account, matched on email or company website, but the mirrored data is read-only in the destination account
  • A lead created in the wrong portal has to be exported and imported by hand, losing activity history and associations
  • Two portals with different property sets and pipelines cannot be merged by field name alone. Each property needs an explicit mapping and an owner
  • Group reporting means someone rebuilding numbers in a spreadsheet from two exports every month

What you can do with a HubSpot to HubSpot integration

Flows we build between HubSpot portals:

  • Push qualifying contacts and companies from a regional or brand portal to a group portal when they reach a lifecycle stage, carrying associations and a link back to the source record ID
  • Sync deals created in one portal into the pipeline of another (for example a shared services or partner portal) and keep stage, amount and close date aligned in both directions with per-property ownership rules
  • Route tickets raised in a customer-facing brand portal to the portal where the support team actually works, and return status and resolution
  • Keep a group-level portal populated with all standard objects from several subsidiaries for consolidated reporting, refreshed on a schedule

HubSpot to HubSpot integration: FAQs

Can two HubSpot portals be connected with HubSpot's own tools?
Partly. HubSpot's multi-account management includes data mirroring, which lets users in one account see contact and company data, activities and associated deals from another account. It needs an Enterprise main account and Professional or Enterprise connected accounts, matches on email address and company website, and the mirrored data is read-only in the destination. If you need records created and updated in both portals, that is a custom integration.
How does a HubSpot to HubSpot integration authenticate?
Each portal gets a private app with only the scopes the sync needs, and the integration uses that portal's private app access token. HubSpot allows up to 20 private apps per account and applies API call limits by tier (190 requests per 10 seconds per app on Professional and Enterprise), and hourly scheduled runs keep comfortably within them.
How long does a HubSpot to HubSpot integration take?
3–5 weeks, depending on scope. Most of the time goes on the property map and the ownership rules between the two portals. The code that moves records is the smaller part.
How much does a HubSpot to HubSpot integration cost?
Custom HubSpot to HubSpot integrations from SpotDev typically start from £5k-£15k. Two portals sharing contacts and companies one way sits at the lower end. Several subsidiaries syncing all standard objects two-way with association mapping sits at the upper end.
