Why teams connect Dun And Bradstreet and HubSpot

Run Dun And Bradstreet and HubSpot side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Dun And Bradstreet is a read-only source: Stacksync reads its data in real time and delivers it into HubSpot, so HubSpot always reflects the current state of Dun And Bradstreet — without exports, scripts, or schedulers.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Common use cases

  • 01 Sync the D&B corporate family tree (parent and subsidiary DUNS) into the CRM so ABM and territory owners see full account hierarchies and roll pipeline up to the global ultimate.
  • 02 Build target-account lists with Criteria Search and land the resulting DUNS plus firmographics in a database for outbound and TAM analysis.
  • 03 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • 04 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.

Common sync patterns

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.

How changes propagate between Dun And Bradstreet and HubSpot

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Dun And Bradstreet HubSpot Interval-based propagation

DetectionStacksync polls Dun And Bradstreet for changes on an incremental schedule, reading only records changed since the previous pass. Polling via D&B Monitoring - register a portfolio of DUNS and pull change notices from the notifications endpoint (retained ~60 days).

DeliveryEach detected change is written to HubSpot through its API, with automatic retries and rate-limit backoff.

HubSpot Dun And Bradstreet Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

DeliveryDun And Bradstreet does not accept inbound record writes, so this direction carries requests rather than records: Dun And Bradstreet's output flows back as field updates on the originating HubSpot records.

Rate-limit considerations

  • Dun And Bradstreet: Per-contract transactions-per-second cap plus weekly/monthly/yearly quotas; exceeding TPS returns HTTP 429 with error 0045/0046 (0047 on spike arrest). Quotas reset on UTC boundaries.
  • HubSpot: Request limits vary by subscription tier and API type.
